14NOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping
15from older versions of FreeBSD, try WITHOUT_CLANG and WITH_GCC to bootstrap to
16the tip of head, and then rebuild without this option. The bootstrap process
17from older version of current across the gcc/clang cutover is a bit fragile.
18
19NOTE TO PEOPLE WHO THINK THAT FreeBSD 12.x IS SLOW:
20	FreeBSD 12.x has many debugging features turned on, in both the kernel
21	and userland.  These features attempt to detect incorrect use of
22	system primitives, and encourage loud failure through extra sanity
23	checking and fail stop semantics.  They also substantially impact
24	system performance.  If you want to do performance measurement,
25	benchmarking, and optimization, you'll want to turn them off.  This
26	includes various WITNESS- related kernel options, INVARIANTS, malloc
27	debugging flags in userland, and various verbose features in the
28	kernel.  Many developers choose to disable these features on build
29	machines to maximize performance.  (To completely disable malloc
30	debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely
31	disable the most expensive debugging functionality run
32	"ln -s 'abort:false,junk:false' /etc/malloc.conf".)
33
34
35****************************** SPECIAL WARNING: ******************************
36
37	Due to a bug in some versions of clang that's very hard to workaround in
38	the upgrade process, to upgrade to -current you must first upgrade
39	either stable/9 after r286035 or stable/10 after r286033 (including
40	10.3-RELEASE) or current after r286007 (including stable/11 and
41	11.0-RELEASE). These revisions post-date the 10.2 and 9.3 releases, so
42	you'll need to take the unusual step of upgrading to the tip of the
43	stable branch before moving to 11 or -current via a source upgrade.
44	stable/11 and 11.0-RELEASE have working newer compiler. This differs
45	from the historical situation where one could upgrade from anywhere on
46	the last couple of stable branches, so be careful.
47
48	If you're running a hybrid system on 9.x or 10.x with an updated clang
49	compiler or are using an supported external toolchain, the build system
50	will allow the upgrade. Otherwise it will print a reminder.
51
52****************************** SPECIAL WARNING: ******************************
53
5420170112:
55	The EM_MULTIQUEUE kernel configuration option is deprecated now that
56	the em(4) driver conforms to iflib specifications.
57
5820170109:
59	The igb(4), em(4) and lem(4) ethernet drivers are now implemented via
60	IFLIB.  If you have a custom kernel configuration that excludes em(4)
61	but you use igb(4), you need to re-add em(4) to your custom configuration.
62
6320161217:
64	Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1.
65	Please see the 20141231 entry below for information about prerequisites
66	and upgrading, if you are not already using clang 3.5.0 or higher.
67
6820161124:
69	Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0.
70	Please see the 20141231 entry below for information about prerequisites
71	and upgrading, if you are not already using clang 3.5.0 or higher.
72
7320161119:
74	The layout of the pmap structure has changed for powerpc to put the pmap
75	statistics at the front for all CPU variations.  libkvm(3) and all tools
76	that link against it need to be recompiled.
77
7820161030:
79	isl(4) and cyapa(4) drivers now require a new driver,
80	chromebook_platform(4), to work properly on Chromebook-class hardware.
81	On other types of hardware the drivers may need to be configured using
82	device hints.  Please see the corresponding manual pages for details.
83
8420161017:
85	The urtwn(4) driver was merged into rtwn(4) and now consists of
86	rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific
87	parts.
88	Also, firmware for RTL8188CE was renamed due to possible name
89	conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B))
90
9120161015:
92	GNU rcs has been removed from base.  It is available as packages:
93	- rcs: Latest GPLv3 GNU rcs version.
94	- rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was
95	removed from base.
96
9720161008:
98	Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control
99	modules now requires that the kernel configuration contain the
100	TCP_HHOOK option. (This option is included in the GENERIC kernel.)
101
10220161003:
103	The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired.
104	ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy.
105
10620160924:
107	Relocatable object files with the extension of .So have been renamed
108	to use an extension of .pico instead.  The purpose of this change is
109	to avoid a name clash with shared libraries on case-insensitive file
110	systems.  On those file systems, foo.So is the same file as foo.so.
111
11220160918:
113	GNU rcs has been turned off by default.  It can (temporarily) be built
114	again by adding WITH_RCS knob in src.conf.
115	Otherwise, GNU rcs is available from packages:
116	- rcs: Latest GPLv3 GNU rcs version.
117	- rcs57: Copy of the latest version of GNU rcs (GPLv2) from base.
118
11920160918:
120	The backup_uses_rcs functionality has been removed from rc.subr.
121
12220160908:
123	The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into
124	two separate components, QUEUE_MACRO_DEBUG_TRACE and
125	QUEUE_MACRO_DEBUG_TRASH.  Define both for the original
126	QUEUE_MACRO_DEBUG behavior.
127
12820160824:
129	r304787 changed some ioctl interfaces between the iSCSI userspace
130	programs and the kernel.  ctladm, ctld, iscsictl, and iscsid must be
131	rebuilt to work with new kernels.  __FreeBSD_version has been bumped
132	to 1200005.
133
13420160818:
135	The UDP receive code has been updated to only treat incoming UDP
136	packets that were addressed to an L2 broadcast address as L3
137	broadcast packets.  It is not expected that this will affect any
138	standards-conforming UDP application.  The new behaviour can be
139	disabled by setting the sysctl net.inet.udp.require_l2_bcast to
140	0.
141
14220160818:
143	Remove the openbsd_poll system call.
144        __FreeBSD_version has been bumped because of this.
145
14620160622:
147	The libc stub for the pipe(2) system call has been replaced with
148	a wrapper that calls the pipe2(2) system call and the pipe(2)
149	system call is now only implemented by the kernels that include
150	"options COMPAT_FREEBSD10" in their config file (this is the
151	default).  Users should ensure that this option is enabled in
152	their kernel or upgrade userspace to r302092 before upgrading their
153	kernel.
154
15520160527:
156	CAM will now strip leading spaces from SCSI disks' serial numbers.
157	This will affect users who create UFS filesystems on SCSI disks using
158	those disk's diskid device nodes.  For example, if /etc/fstab
159	previously contained a line like
160	"/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should
161	change it to "/dev/diskid/DISK-ABCDEFG0123456".  Users of geom
162	transforms like gmirror may also be affected.  ZFS users should
163	generally be fine.
164
16520160523:
166	The bitstring(3) API has been updated with new functionality and
167	improved performance.  But it is binary-incompatible with the old API.
168	Objects built with the new headers may not be linked against objects
169	built with the old headers.
170
17120160520:
172	The brk and sbrk functions have been removed from libc on arm64.
173	Binutils from ports has been updated to not link to these
174	functions and should be updated to the latest version before
175	installing a new libc.
176
17720160517:
178	The armv6 port now defaults to hard float ABI. Limited support
179	for running both hardfloat and soft float on the same system
180	is available using the libraries installed with -DWITH_LIBSOFT.
181	This has only been tested as an upgrade path for installworld
182	and packages may fail or need manual intervention to run. New
183	packages will be needed.
184
185	To update an existing self-hosted armv6hf system, you must add
186	TARGET_ARCH=armv6 on the make command line for both the build
187	and the install steps.
188
18920160510:
190	Kernel modules compiled outside of a kernel build now default to
191	installing to /boot/modules instead of /boot/kernel.  Many kernel
192	modules built this way (such as those in ports) already overrode
193	KMODDIR explicitly to install into /boot/modules.  However,
194	manually building and installing a module from /sys/modules will
195	now install to /boot/modules instead of /boot/kernel.
196
19720160414:
198	The CAM I/O scheduler has been committed to the kernel. There should be
199	no user visible impact. This does enable NCQ Trim on ada SSDs. While the
200	list of known rogues that claim support for this but actually corrupt
201	data is believed to be complete, be on the lookout for data
202	corruption. The known rogue list is believed to be complete:
203
204		o Crucial MX100, M550 drives with MU01 firmware.
205		o Micron M510 and M550 drives with MU01 firmware.
206		o Micron M500 prior to MU07 firmware
207		o Samsung 830, 840, and 850 all firmwares
208		o FCCT M500 all firmwares
209
210	Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware
211	with working NCQ TRIM. For Micron branded drives, see your sales rep for
212	updated firmware. Black listed drives will work correctly because these
213	drives work correctly so long as no NCQ TRIMs are sent to them. Given
214	this list is the same as found in Linux, it's believed there are no
215	other rogues in the market place. All other models from the above
216	vendors work.
217
218	To be safe, if you are at all concerned, you can quirk each of your
219	drives to prevent NCQ from being sent by setting:
220		kern.cam.ada.X.quirks="0x2"
221	in loader.conf. If the drive requires the 4k sector quirk, set the
222	quirks entry to 0x3.
223
22420160330:
225	The FAST_DEPEND build option has been removed and its functionality is
226	now the one true way.  The old mkdep(1) style of 'make depend' has
227	been removed.  See 20160311 for further details.
228
22920160317:
230	Resource range types have grown from unsigned long to uintmax_t.  All
231	drivers, and anything using libdevinfo, need to be recompiled.
232
23320160311:
234	WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree
235	builds.  It no longer runs mkdep(1) during 'make depend', and the
236	'make depend' stage can safely be skipped now as it is auto ran
237	when building 'make all' and will generate all SRCS and DPSRCS before
238	building anything else.  Dependencies are gathered at compile time with
239	-MF flags kept in separate .depend files per object file.  Users should
240	run 'make cleandepend' once if using -DNO_CLEAN to clean out older
241	stale .depend files.
242
24320160306:
244	On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into
245	kernel modules.  Therefore, if you load any kernel modules at boot time,
246	please install the boot loaders after you install the kernel, but before
247	rebooting, e.g.:
248
249	make buildworld
250	make kernel KERNCONF=YOUR_KERNEL_HERE
251	make -C sys/boot install
252	<reboot in single user>
253
254	Then follow the usual steps, described in the General Notes section,
255	below.
256
25720160305:
258	Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0.  Please
259	see the 20141231 entry below for information about prerequisites and
260	upgrading, if you are not already using clang 3.5.0 or higher.
261
26220160301:
263	The AIO subsystem is now a standard part of the kernel.  The
264	VFS_AIO kernel option and aio.ko kernel module have been removed.
265	Due to stability concerns, asynchronous I/O requests are only
266	permitted on sockets and raw disks by default.  To enable
267	asynchronous I/O requests on all file types, set the
268	vfs.aio.enable_unsafe sysctl to a non-zero value.
269
27020160226:
271	The ELF object manipulation tool objcopy is now provided by the
272	ELF Tool Chain project rather than by GNU binutils. It should be a
273	drop-in replacement, with the addition of arm64 support. The
274	(temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set
275	to obtain the GNU version if necessary.
276
27720160129:
278	Building ZFS pools on top of zvols is prohibited by default.  That
279	feature has never worked safely; it's always been prone to deadlocks.
280	Using a zvol as the backing store for a VM guest's virtual disk will
281	still work, even if the guest is using ZFS.  Legacy behavior can be
282	restored by setting vfs.zfs.vol.recursive=1.
283
28420160119:
285	The NONE and HPN patches has been removed from OpenSSH.  They are
286	still available in the security/openssh-portable port.
287
28820160113:
289	With the addition of ypldap(8), a new _ypldap user is now required
290	during installworld. "mergemaster -p" can be used to add the user
291	prior to installworld, as documented in the handbook.
292
29320151216:
294	The tftp loader (pxeboot) now uses the option root-path directive. As a
295	consequence it no longer looks for a pxeboot.4th file on the tftp
296	server. Instead it uses the regular /boot infrastructure as with the
297	other loaders.
298
29920151211:
300	The code to start recording plug and play data into the modules has
301	been committed. While the old tools will properly build a new kernel,
302	a number of warnings about "unknown metadata record 4" will be produced
303	for an older kldxref. To avoid such warnings, make sure to rebuild
304	the kernel toolchain (or world). Make sure that you have r292078 or
305	later when trying to build 292077 or later before rebuilding.
306
30720151207:
308	Debug data files are now built by default with 'make buildworld' and
309	installed with 'make installworld'. This facilitates debugging but
310	requires more disk space both during the build and for the installed
311	world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes
312	in src.conf(5).
313
31420151130:
315	r291527 changed the internal interface between the nfsd.ko and
316	nfscommon.ko modules. As such, they must both be upgraded to-gether.
317	__FreeBSD_version has been bumped because of this.
318
31920151108:
320	Add support for unicode collation strings leads to a change of
321	order of files listed by ls(1) for example. To get back to the old
322	behaviour, set LC_COLLATE environment variable to "C".
323
324	Databases administrators will need to reindex their databases given
325	collation results will be different.
326
327	Due to a bug in install(1) it is recommended to remove the ancient
328	locales before running make installworld.
329
330	rm -rf /usr/share/locale/*
331
33220151030:
333	The OpenSSL has been upgraded to 1.0.2d.  Any binaries requiring
334	libcrypto.so.7 or libssl.so.7 must be recompiled.
335
33620151020:
337	Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0.
338	Kernel modules isp_2400_multi and isp_2500_multi were removed and
339	should be replaced with isp_2400 and isp_2500 modules respectively.
340
34120151017:
342	The build previously allowed using 'make -n' to not recurse into
343	sub-directories while showing what commands would be executed, and
344	'make -n -n' to recursively show commands.  Now 'make -n' will recurse
345	and 'make -N' will not.
346
34720151012:
348	If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster
349	and etcupdate will now use this file. A custom sendmail.cf is now
350	updated via this mechanism rather than via installworld.  If you had
351	excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may
352	want to remove the exclusion or change it to "always install".
353	/etc/mail/sendmail.cf is now managed the same way regardless of
354	whether SENDMAIL_MC/SENDMAIL_CF is used.  If you are not using
355	SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior.
356
35720151011:
358	Compatibility shims for legacy ATA device names have been removed.
359	It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases
360	and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.*
361	environment variables, /dev/ad* and /dev/ar* symbolic links.
362
36320151006:
364	Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0.
365	Please see the 20141231 entry below for information about prerequisites
366	and upgrading, if you are not already using clang 3.5.0 or higher.
367
36820150924:
369	Kernel debug files have been moved to /usr/lib/debug/boot/kernel/,
370	and renamed from .symbols to .debug. This reduces the size requirements
371	on the boot partition or file system and provides consistency with
372	userland debug files.
373
374	When using the supported kernel installation method the
375	/usr/lib/debug/boot/kernel directory will be renamed (to kernel.old)
376	as is done with /boot/kernel.
377
378	Developers wishing to maintain the historical behavior of installing
379	debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5).
380
38120150827:
382	The wireless drivers had undergone changes that remove the 'parent
383	interface' from the ifconfig -l output. The rc.d network scripts
384	used to check presence of a parent interface in the list, so old
385	scripts would fail to start wireless networking. Thus, etcupdate(3)
386	or mergemaster(8) run is required after kernel update, to update your
387	rc.d scripts in /etc.
388
38920150827:
390	pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl'
391	These configurations are now automatically interpreted as
392	'scrub fragment reassemble'.
393
39420150817:
395	Kernel-loadable modules for the random(4) device are back. To use
396	them, the kernel must have
397
398	device	random
399	options	RANDOM_LOADABLE
400
401	kldload(8) can then be used to load random_fortuna.ko
402	or random_yarrow.ko. Please note that due to the indirect
403	function calls that the loadable modules need to provide,
404	the build-in variants will be slightly more efficient.
405
406	The random(4) kernel option RANDOM_DUMMY has been retired due to
407	unpopularity. It was not all that useful anyway.
408
40920150813:
410	The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired.
411	Control over building the ELF Tool Chain tools is now provided by
412	the WITHOUT_TOOLCHAIN knob.
413
41420150810:
415	The polarity of Pulse Per Second (PPS) capture events with the
416	uart(4) driver has been corrected.  Prior to this change the PPS
417	"assert" event corresponded to the trailing edge of a positive PPS
418	pulse and the "clear" event was the leading edge of the next pulse.
419
420	As the width of a PPS pulse in a typical GPS receiver is on the
421	order of 1 millisecond, most users will not notice any significant
422	difference with this change.
423
424	Anyone who has compensated for the historical polarity reversal by
425	configuring a negative offset equal to the pulse width will need to
426	remove that workaround.
427
42820150809:
429	The default group assigned to /dev/dri entries has been changed
430	from 'wheel' to 'video' with the id of '44'. If you want to have
431	access to the dri devices please add yourself to the video group
432	with:
433
434	# pw groupmod video -m $USER
435
43620150806:
437	The menu.rc and loader.rc files will now be replaced during
438	upgrades. Please migrate local changes to menu.rc.local and
439	loader.rc.local instead.
440
44120150805:
442	GNU Binutils versions of addr2line, c++filt, nm, readelf, size,
443	strings and strip have been removed. The src.conf(5) knob
444	WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools.
445
44620150728:
447	As ZFS requires more kernel stack pages than is the default on some
448	architectures e.g. i386, it now warns if KSTACK_PAGES is less than
449	ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing).
450
451	Please consider using 'options KSTACK_PAGES=X' where X is greater
452	than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations.
453
45420150706:
455	sendmail has been updated to 8.15.2.  Starting with FreeBSD 11.0
456	and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by
457	default, i.e., they will not contain "::".  For example, instead
458	of ::1, it will be 0:0:0:0:0:0:0:1.  This permits a zero subnet
459	to have a more specific match, such as different map entries for
460	IPv6:0:0 vs IPv6:0.  This change requires that configuration
461	data (including maps, files, classes, custom ruleset, etc.) must
462	use the same format, so make certain such configuration data is
463	upgrading.  As a very simple check search for patterns like
464	'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'.  To return to the old
465	behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or
466	the cf option UseCompressedIPv6Addresses.
467
46820150630:
469	The default kernel entropy-processing algorithm is now
470	Fortuna, replacing Yarrow.
471
472	Assuming you have 'device random' in your kernel config
473	file, the configurations allow a kernel option to override
474	this default. You may choose *ONE* of:
475
476	options	RANDOM_YARROW	# Legacy /dev/random algorithm.
477	options	RANDOM_DUMMY	# Blocking-only driver.
478
479	If you have neither, you get Fortuna.  For most people,
480	read no further, Fortuna will give a /dev/random that works
481	like it always used to, and the difference will be irrelevant.
482
483	If you remove 'device random', you get *NO* kernel-processed
484	entropy at all. This may be acceptable to folks building
485	embedded systems, but has complications. Carry on reading,
486	and it is assumed you know what you need.
487
488	*PLEASE* read random(4) and random(9) if you are in the
489	habit of tweaking kernel configs, and/or if you are a member
490	of the embedded community, wanting specific and not-usual
491	behaviour from your security subsystems.
492
493	NOTE!! If you use RANDOM_DUMMY and/or have no 'device
494	random', you will NOT have a functioning /dev/random, and
495	many cryptographic features will not work, including SSH.
496	You may also find strange behaviour from the random(3) set
497	of library functions, in particular sranddev(3), srandomdev(3)
498	and arc4random(3). The reason for this is that the KERN_ARND
499	sysctl only returns entropy if it thinks it has some to
500	share, and with RANDOM_DUMMY or no 'device random' this
501	will never happen.
502
50320150623:
504	An additional fix for the issue described in the 20150614 sendmail
505	entry below has been been committed in revision 284717.
506
50720150616:
508	FreeBSD's old make (fmake) has been removed from the system. It is
509	available as the devel/fmake port or via pkg install fmake.
510
51120150615:
512	The fix for the issue described in the 20150614 sendmail entry
513	below has been been committed in revision 284436.  The work
514	around described in that entry is no longer needed unless the
515	default setting is overridden by a confDH_PARAMETERS configuration
516	setting of '5' or pointing to a 512 bit DH parameter file.
517
51820150614:
519	ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from
520	atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf
521	and devel/kyua to version 0.20+ and adjust any calling code to work
522	with Kyuafile and kyua.
523
52420150614:
525	The import of openssl to address the FreeBSD-SA-15:10.openssl
526	security advisory includes a change which rejects handshakes
527	with DH parameters below 768 bits.  sendmail releases prior
528	to 8.15.2 (not yet released), defaulted to a 512 bit
529	DH parameter setting for client connections.  To work around
530	this interoperability, sendmail can be configured to use a
531	2048 bit DH parameter by:
532
533	1. Edit /etc/mail/`hostname`.mc
534	2. If a setting for confDH_PARAMETERS does not exist or
535	   exists and is set to a string beginning with '5',
536	   replace it with '2'.
537	3. If a setting for confDH_PARAMETERS exists and is set to
538	   a file path, create a new file with:
539		openssl dhparam -out /path/to/file 2048
540	4. Rebuild the .cf file:
541		cd /etc/mail/; make; make install
542	5. Restart sendmail:
543		cd /etc/mail/; make restart
544
545	A sendmail patch is coming, at which time this file will be
546	updated.
547
54820150604:
549	Generation of legacy formatted entries have been disabled by default
550	in pwd_mkdb(8), as all base system consumers of the legacy formatted
551	entries were converted to use the new format by default when the new,
552	machine independent format have been added and supported since FreeBSD
553	5.x.
554
555	Please see the pwd_mkdb(8) manual page for further details.
556
55720150525:
558	Clang and llvm have been upgraded to 3.6.1 release.  Please see the
559	20141231 entry below for information about prerequisites and upgrading,
560	if you are not already using 3.5.0 or higher.
561
56220150521:
563	TI platform code switched to using vendor DTS files and this update
564	may break existing systems running on Beaglebone, Beaglebone Black,
565	and Pandaboard:
566
567	- dtb files should be regenerated/reinstalled. Filenames are the
568	  same but content is different now
569	- GPIO addressing was changed, now each GPIO bank (32 pins per bank)
570	  has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old
571	  addressing scheme is now pin 25 on /dev/gpioc3.
572	- Pandaboard: /etc/ttys should be updated, serial console device is
573	  now /dev/ttyu2, not /dev/ttyu0
574
57520150501:
576	soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim.
577	If you need the GNU extension from groff soelim(1), install groff
578	from package: pkg install groff, or via ports: textproc/groff.
579
58020150423:
581	chmod, chflags, chown and chgrp now affect symlinks in -R mode as
582	defined in symlink(7); previously symlinks were silently ignored.
583
58420150415:
585	The const qualifier has been removed from iconv(3) to comply with
586	POSIX.  The ports tree is aware of this from r384038 onwards.
587
58820150416:
589	Libraries specified by LIBADD in Makefiles must have a corresponding
590	DPADD_<lib> variable to ensure correct dependencies.  This is now
591	enforced in src.libnames.mk.
592
59320150324:
594	From legacy ata(4) driver was removed support for SATA controllers
595	supported by more functional drivers ahci(4), siis(4) and mvs(4).
596	Kernel modules ataahci and ataadaptec were removed completely,
597	replaced by ahci and mvs modules respectively.
598
59920150315:
600	Clang, llvm and lldb have been upgraded to 3.6.0 release.  Please see
601	the 20141231 entry below for information about prerequisites and
602	upgrading, if you are not already using 3.5.0 or higher.
603
60420150307:
605	The 32-bit PowerPC kernel has been changed to a position-independent
606	executable. This can only be booted with a version of loader(8)
607	newer than January 31, 2015, so make sure to update both world and
608	kernel before rebooting.
609
61020150217:
611	If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014),
612	but before r278950, the RNG was not seeded properly.  Immediately
613	upgrade the kernel to r278950 or later and regenerate any keys (e.g.
614	ssh keys or openssl keys) that were generated w/ a kernel from that
615	range.  This does not affect programs that directly used /dev/random
616	or /dev/urandom.  All userland uses of arc4random(3) are affected.
617
61820150210:
619	The autofs(4) ABI was changed in order to restore binary compatibility
620	with 10.1-RELEASE.  The automountd(8) daemon needs to be rebuilt to work
621	with the new kernel.
622
62320150131:
624	The powerpc64 kernel has been changed to a position-independent
625	executable. This can only be booted with a new version of loader(8),
626	so make sure to update both world and kernel before rebooting.
627
62820150118:
629	Clang and llvm have been upgraded to 3.5.1 release.  This is a bugfix
630	only release, no new features have been added.  Please see the 20141231
631	entry below for information about prerequisites and upgrading, if you
632	are not already using 3.5.0.
633
63420150107:
635	ELF tools addr2line, elfcopy (strip), nm, size, and strings are now
636	taken from the ELF Tool Chain project rather than GNU binutils. They
637	should be drop-in replacements, with the addition of arm64 support.
638	The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the
639	binutils tools, if necessary. See 20150805 for updated information.
640
64120150105:
642	The default Unbound configuration now enables remote control
643	using a local socket.  Users who have already enabled the
644	local_unbound service should regenerate their configuration
645	by running "service local_unbound setup" as root.
646
64720150102:
648	The GNU texinfo and GNU info pages have been removed.
649	To be able to view GNU info pages please install texinfo from ports.
650
65120141231:
652	Clang, llvm and lldb have been upgraded to 3.5.0 release.
653
654	As of this release, a prerequisite for building clang, llvm and lldb is
655	a C++11 capable compiler and C++11 standard library.  This means that to
656	be able to successfully build the cross-tools stage of buildworld, with
657	clang as the bootstrap compiler, your system compiler or cross compiler
658	should either be clang 3.3 or later, or gcc 4.8 or later, and your
659	system C++ library should be libc++, or libdstdc++ from gcc 4.8 or
660	later.
661
662	On any standard FreeBSD 10.x or 11.x installation, where clang and
663	libc++ are on by default (that is, on x86 or arm), this should work out
664	of the box.
665
666	On 9.x installations where clang is enabled by default, e.g. on x86 and
667	powerpc, libc++ will not be enabled by default, so libc++ should be
668	built (with clang) and installed first.  If both clang and libc++ are
669	missing, build clang first, then use it to build libc++.
670
671	On 8.x and earlier installations, upgrade to 9.x first, and then follow
672	the instructions for 9.x above.
673
674	Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by
675	default, and do not build clang.
676
677	Many embedded systems are resource constrained, and will not be able to
678	build clang in a reasonable time, or in some cases at all.  In those
679	cases, cross building bootable systems on amd64 is a workaround.
680
681	This new version of clang introduces a number of new warnings, of which
682	the following are most likely to appear:
683
684	-Wabsolute-value
685
686	This warns in two cases, for both C and C++:
687	* When the code is trying to take the absolute value of an unsigned
688	  quantity, which is effectively a no-op, and almost never what was
689	  intended.  The code should be fixed, if at all possible.  If you are
690	  sure that the unsigned quantity can be safely cast to signed, without
691	  loss of information or undefined behavior, you can add an explicit
692	  cast, or disable the warning.
693
694	* When the code is trying to take an absolute value, but the called
695	  abs() variant is for the wrong type, which can lead to truncation.
696	  If you want to disable the warning instead of fixing the code, please
697	  make sure that truncation will not occur, or it might lead to unwanted
698	  side-effects.
699
700	-Wtautological-undefined-compare and
701	-Wundefined-bool-conversion
702
703	These warn when C++ code is trying to compare 'this' against NULL, while
704	'this' should never be NULL in well-defined C++ code.  However, there is
705	some legacy (pre C++11) code out there, which actively abuses this
706	feature, which was less strictly defined in previous C++ versions.
707
708	Squid and openjdk do this, for example.  The warning can be turned off
709	for C++98 and earlier, but compiling the code in C++11 mode might result
710	in unexpected behavior; for example, the parts of the program that are
711	unreachable could be optimized away.
712
71320141222:
714	The old NFS client and server (kernel options NFSCLIENT, NFSSERVER)
715	kernel sources have been removed. The .h files remain, since some
716	utilities include them. This will need to be fixed later.
717	If "mount -t oldnfs ..." is attempted, it will fail.
718	If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used,
719	the utilities will report errors.
720
72120141121:
722	The handling of LOCAL_LIB_DIRS has been altered to skip addition of
723	directories to top level SUBDIR variable when their parent
724	directory is included in LOCAL_DIRS.  Users with build systems with
725	such hierarchies and without SUBDIR entries in the parent
726	directory Makefiles should add them or add the directories to
727	LOCAL_DIRS.
728
72920141109:
730	faith(4) and faithd(8) have been removed from the base system. Faith
731	has been obsolete for a very long time.
732
73320141104:
734	vt(4), the new console driver, is enabled by default. It brings
735	support for Unicode and double-width characters, as well as
736	support for UEFI and integration with the KMS kernel video
737	drivers.
738
739	You may need to update your console settings in /etc/rc.conf,
740	most probably the keymap. During boot, /etc/rc.d/syscons will
741	indicate what you need to do.
742
743	vt(4) still has issues and lacks some features compared to
744	syscons(4). See the wiki for up-to-date information:
745	  https://wiki.freebsd.org/Newcons
746
747	If you want to keep using syscons(4), you can do so by adding
748	the following line to /boot/loader.conf:
749	  kern.vty=sc
750
75120141102:
752	pjdfstest has been integrated into kyua as an opt-in test suite.
753	Please see share/doc/pjdfstest/README for more details on how to
754	execute it.
755
75620141009:
757	gperf has been removed from the base system for architectures
758	that use clang. Ports that require gperf will obtain it from the
759	devel/gperf port.
760
76120140923:
762	pjdfstest has been moved from tools/regression/pjdfstest to
763	contrib/pjdfstest .
764
76520140922:
766	At svn r271982, The default linux compat kernel ABI has been adjusted
767	to 2.6.18 in support of the linux-c6 compat ports infrastructure
768	update.  If you wish to continue using the linux-f10 compat ports,
769	add compat.linux.osrelease=2.6.16 to your local sysctl.conf.  Users are
770	encouraged to update their linux-compat packages to linux-c6 during
771	their next update cycle.
772
77320140729:
774	The ofwfb driver, used to provide a graphics console on PowerPC when
775	using vt(4), no longer allows mmap() of all physical memory. This
776	will prevent Xorg on PowerPC with some ATI graphics cards from
777	initializing properly unless x11-servers/xorg-server is updated to
778	1.12.4_8 or newer.
779
78020140723:
781	The xdev targets have been converted to using TARGET and
782	TARGET_ARCH instead of XDEV and XDEV_ARCH.
783
78420140719:
785	The default unbound configuration has been modified to address
786	issues with reverse lookups on networks that use private
787	address ranges.  If you use the local_unbound service, run
788	"service local_unbound setup" as root to regenerate your
789	configuration, then "service local_unbound reload" to load the
790	new configuration.
791
79220140709:
793	The GNU texinfo and GNU info pages are not built and installed
794	anymore, WITH_INFO knob has been added to allow to built and install
795	them again.
796	UPDATE: see 20150102 entry on texinfo's removal
797
79820140708:
799	The GNU readline library is now an INTERNALLIB - that is, it is
800	statically linked into consumers (GDB and variants) in the base
801	system, and the shared library is no longer installed.  The
802	devel/readline port is available for third party software that
803	requires readline.
804
80520140702:
806	The Itanium architecture (ia64) has been removed from the list of
807	known architectures. This is the first step in the removal of the
808	architecture.
809
81020140701:
811	Commit r268115 has added NFSv4.1 server support, merged from
812	projects/nfsv4.1-server.  Since this includes changes to the
813	internal interfaces between the NFS related modules, a full
814	build of the kernel and modules will be necessary.
815	__FreeBSD_version has been bumped.
816
81720140629:
818	The WITHOUT_VT_SUPPORT kernel config knob has been renamed
819	WITHOUT_VT.  (The other _SUPPORT knobs have a consistent meaning
820	which differs from the behaviour controlled by this knob.)
821
82220140619:
823	Maximal length of the serial number in CTL was increased from 16 to
824	64 chars, that breaks ABI.  All CTL-related tools, such as ctladm
825	and ctld, need to be rebuilt to work with a new kernel.
826
82720140606:
828	The libatf-c and libatf-c++ major versions were downgraded to 0 and
829	1 respectively to match the upstream numbers.  They were out of
830	sync because, when they were originally added to FreeBSD, the
831	upstream versions were not respected.  These libraries are private
832	and not yet built by default, so renumbering them should be a
833	non-issue.  However, unclean source trees will yield broken test
834	programs once the operator executes "make delete-old-libs" after a
835	"make installworld".
836
837	Additionally, the atf-sh binary was made private by moving it into
838	/usr/libexec/.  Already-built shell test programs will keep the
839	path to the old binary so they will break after "make delete-old"
840	is run.
841
842	If you are using WITH_TESTS=yes (not the default), wipe the object
843	tree and rebuild from scratch to prevent spurious test failures.
844	This is only needed once: the misnumbered libraries and misplaced
845	binaries have been added to OptionalObsoleteFiles.inc so they will
846	be removed during a clean upgrade.
847
84820140512:
849	Clang and llvm have been upgraded to 3.4.1 release.
850
85120140508:
852	We bogusly installed src.opts.mk in /usr/share/mk. This file should
853	be removed to avoid issues in the future (and has been added to
854	ObsoleteFiles.inc).
855
85620140505:
857	/etc/src.conf now affects only builds of the FreeBSD src tree. In the
858	past, it affected all builds that used the bsd.*.mk files. The old
859	behavior was a bug, but people may have relied upon it. To get this
860	behavior back, you can .include /etc/src.conf from /etc/make.conf
861	(which is still global and isn't changed). This also changes the
862	behavior of incremental builds inside the tree of individual
863	directories. Set MAKESYSPATH to ".../share/mk" to do that.
864	Although this has survived make universe and some upgrade scenarios,
865	other upgrade scenarios may have broken. At least one form of
866	temporary breakage was fixed with MAKESYSPATH settings for buildworld
867	as well... In cases where MAKESYSPATH isn't working with this
868	setting, you'll need to set it to the full path to your tree.
869
870	One side effect of all this cleaning up is that bsd.compiler.mk
871	is no longer implicitly included by bsd.own.mk. If you wish to
872	use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk
873	as well.
874
87520140430:
876	The lindev device has been removed since /dev/full has been made a
877	standard device.  __FreeBSD_version has been bumped.
878
87920140424:
880	The knob WITHOUT_VI was added to the base system, which controls
881	building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1)
882	in order to reorder files share/termcap and didn't build ex(1) as a
883	build tool, so building/installing with WITH_VI is highly advised for
884	build hosts for older releases.
885
886	This issue has been fixed in stable/9 and stable/10 in r277022 and
887	r276991, respectively.
888
88920140418:
890	The YES_HESIOD knob has been removed. It has been obsolete for
891	a decade. Please move to using WITH_HESIOD instead or your builds
892	will silently lack HESIOD.
893
89420140405:
895	The uart(4) driver has been changed with respect to its handling
896	of the low-level console. Previously the uart(4) driver prevented
897	any process from changing the baudrate or the CLOCAL and HUPCL
898	control flags. By removing the restrictions, operators can make
899	changes to the serial console port without having to reboot.
900	However, when getty(8) is started on the serial device that is
901	associated with the low-level console, a misconfigured terminal
902	line in /etc/ttys will now have a real impact.
903	Before upgrading the kernel, make sure that /etc/ttys has the
904	serial console device configured as 3wire without baudrate to
905	preserve the previous behaviour. E.g:
906	    ttyu0  "/usr/libexec/getty 3wire"  vt100  on  secure
907
90820140306:
909	Support for libwrap (TCP wrappers) in rpcbind was disabled by default
910	to improve performance.  To re-enable it, if needed, run rpcbind
911	with command line option -W.
912
91320140226:
914	Switched back to the GPL dtc compiler due to updates in the upstream
915	dts files not being supported by the BSDL dtc compiler. You will need
916	to rebuild your kernel toolchain to pick up the new compiler. Core dumps
917	may result while building dtb files during a kernel build if you fail
918	to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler.
919
92020140216:
921	Clang and llvm have been upgraded to 3.4 release.
922
92320140216:
924	The nve(4) driver has been removed.  Please use the nfe(4) driver
925	for NVIDIA nForce MCP Ethernet adapters instead.
926
92720140212:
928	An ABI incompatibility crept into the libc++ 3.4 import in r261283.
929	This could cause certain C++ applications using shared libraries built
930	against the previous version of libc++ to crash.  The incompatibility
931	has now been fixed, but any C++ applications or shared libraries built
932	between r261283 and r261801 should be recompiled.
933
93420140204:
935	OpenSSH will now ignore errors caused by kernel lacking of Capsicum
936	capability mode support.  Please note that enabling the feature in
937	kernel is still highly recommended.
938
93920140131:
940	OpenSSH is now built with sandbox support, and will use sandbox as
941	the default privilege separation method.  This requires Capsicum
942	capability mode support in kernel.
943
94420140128:
945	The libelf and libdwarf libraries have been updated to newer
946	versions from upstream. Shared library version numbers for
947	these two libraries were bumped. Any ports or binaries
948	requiring these two libraries should be recompiled.
949	__FreeBSD_version is bumped to 1100006.
950
95120140110:
952	If a Makefile in a tests/ directory was auto-generating a Kyuafile
953	instead of providing an explicit one, this would prevent such
954	Makefile from providing its own Kyuafile in the future during
955	NO_CLEAN builds.  This has been fixed in the Makefiles but manual
956	intervention is needed to clean an objdir if you use NO_CLEAN:
957	  # find /usr/obj -name Kyuafile | xargs rm -f
958
95920131213:
960	The behavior of gss_pseudo_random() for the krb5 mechanism
961	has changed, for applications requesting a longer random string
962	than produced by the underlying enctype's pseudo-random() function.
963	In particular, the random string produced from a session key of
964	enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will
965	be different at the 17th octet and later, after this change.
966	The counter used in the PRF+ construction is now encoded as a
967	big-endian integer in accordance with RFC 4402.
968	__FreeBSD_version is bumped to 1100004.
969
97020131108:
971	The WITHOUT_ATF build knob has been removed and its functionality
972	has been subsumed into the more generic WITHOUT_TESTS.  If you were
973	using the former to disable the build of the ATF libraries, you
974	should change your settings to use the latter.
975
97620131025:
977	The default version of mtree is nmtree which is obtained from
978	NetBSD.  The output is generally the same, but may vary
979	slightly.  If you found you need identical output adding
980	"-F freebsd9" to the command line should do the trick.  For the
981	time being, the old mtree is available as fmtree.
982
98320131014:
984	libbsdyml has been renamed to libyaml and moved to /usr/lib/private.
985	This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg
986	1.1.4_8 and verify bsdyml not linked in, before running "make
987	delete-old-libs":
988	  # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean
989	  or
990	  # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml
991
99220131010:
993	The stable/10 branch has been created in subversion from head
994	revision r256279.
995
99620131010:
997	The rc.d/jail script has been updated to support jail(8)
998	configuration file.  The "jail_<jname>_*" rc.conf(5) variables
999	for per-jail configuration are automatically converted to
1000	/var/run/jail.<jname>.conf before the jail(8) utility is invoked.
1001	This is transparently backward compatible.  See below about some
1002	incompatibilities and rc.conf(5) manual page for more details.
1003
1004	These variables are now deprecated in favor of jail(8) configuration
1005	file.  One can use "rc.d/jail config <jname>" command to generate
1006	a jail(8) configuration file in /var/run/jail.<jname>.conf without
1007	running the jail(8) utility.   The default pathname of the
1008	configuration file is /etc/jail.conf and can be specified by
1009	using $jail_conf or $jail_<jname>_conf variables.
1010
1011	Please note that jail_devfs_ruleset accepts an integer at
1012	this moment.  Please consider to rewrite the ruleset name
1013	with an integer.
1014
101520130930:
1016	BIND has been removed from the base system.  If all you need
1017	is a local resolver, simply enable and start the local_unbound
1018	service instead.  Otherwise, several versions of BIND are
1019	available in the ports tree.   The dns/bind99 port is one example.
1020
1021	With this change, nslookup(1) and dig(1) are no longer in the base
1022	system.  Users should instead use host(1) and drill(1) which are
1023	in the base system.  Alternatively, nslookup and dig can
1024	be obtained by installing the dns/bind-tools port.
1025
102620130916:
1027	With the addition of unbound(8), a new unbound user is now
1028	required during installworld.  "mergemaster -p" can be used to
1029	add the user prior to installworld, as documented in the handbook.
1030
103120130911:
1032	OpenSSH is now built with DNSSEC support, and will by default
1033	silently trust signed SSHFP records.  This can be controlled with
1034	the VerifyHostKeyDNS client configuration setting.  DNSSEC support
1035	can be disabled entirely with the WITHOUT_LDNS option in src.conf.
1036
103720130906:
1038	The GNU Compiler Collection and C++ standard library (libstdc++)
1039	are no longer built by default on platforms where clang is the system
1040	compiler.  You can enable them with the WITH_GCC and WITH_GNUCXX
1041	options in src.conf.
1042
104320130905:
1044	The PROCDESC kernel option is now part of the GENERIC kernel
1045	configuration and is required for the rwhod(8) to work.
1046	If you are using custom kernel configuration, you should include
1047	'options PROCDESC'.
1048
104920130905:
1050	The API and ABI related to the Capsicum framework was modified
1051	in backward incompatible way. The userland libraries and programs
1052	have to be recompiled to work with the new kernel. This includes the
1053	following libraries and programs, but the whole buildworld is
1054	advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl,
1055	kdump, procstat, rwho, rwhod, uniq.
1056
105720130903:
1058	AES-NI intrinsic support has been added to gcc.  The AES-NI module
1059	has been updated to use this support.  A new gcc is required to build
1060	the aesni module on both i386 and amd64.
1061
106220130821:
1063	The PADLOCK_RNG and RDRAND_RNG kernel options are now devices.
1064	Thus "device padlock_rng" and "device rdrand_rng" should be
1065	used instead of "options PADLOCK_RNG" & "options RDRAND_RNG".
1066
106720130813:
1068	WITH_ICONV has been split into two feature sets.  WITH_ICONV now
1069	enables just the iconv* functionality and is now on by default.
1070	WITH_LIBICONV_COMPAT enables the libiconv api and link time
1071	compatibility.  Set WITHOUT_ICONV to build the old way.
1072	If you have been using WITH_ICONV before, you will very likely
1073	need to turn on WITH_LIBICONV_COMPAT.
1074
107520130806:
1076	INVARIANTS option now enables DEBUG for code with OpenSolaris and
1077	Illumos origin, including ZFS.  If you have INVARIANTS in your
1078	kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG
1079	explicitly.
1080	DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS)
1081	locks if WITNESS option was set.  Because that generated a lot of
1082	witness(9) reports and all of them were believed to be false
1083	positives, this is no longer done.  New option OPENSOLARIS_WITNESS
1084	can be used to achieve the previous behavior.
1085
108620130806:
1087	Timer values in IPv6 data structures now use time_uptime instead
1088	of time_second.  Although this is not a user-visible functional
1089	change, userland utilities which directly use them---ndp(8),
1090	rtadvd(8), and rtsold(8) in the base system---need to be updated
1091	to r253970 or later.
1092
109320130802:
1094	find -delete can now delete the pathnames given as arguments,
1095	instead of only files found below them or if the pathname did
1096	not contain any slashes. Formerly, the following error message
1097	would result:
1098
1099	find: -delete: <path>: relative path potentially not safe
1100
1101	Deleting the pathnames given as arguments can be prevented
1102	without error messages using -mindepth 1 or by changing
1103	directory and passing "." as argument to find. This works in the
1104	old as well as the new version of find.
1105
110620130726:
1107	Behavior of devfs rules path matching has been changed.
1108	Pattern is now always matched against fully qualified devfs
1109	path and slash characters must be explicitly matched by
1110	slashes in pattern (FNM_PATHNAME). Rulesets involving devfs
1111	subdirectories must be reviewed.
1112
111320130716:
1114	The default ARM ABI has changed to the ARM EABI. The old ABI is
1115	incompatible with the ARM EABI and all programs and modules will
1116	need to be rebuilt to work with a new kernel.
1117
1118	To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set.
1119
1120	NOTE: Support for the old ABI will be removed in the future and
1121	users are advised to upgrade.
1122
112320130709:
1124	pkg_install has been disconnected from the build if you really need it
1125	you should add WITH_PKGTOOLS in your src.conf(5).
1126
112720130709:
1128	Most of network statistics structures were changed to be able
1129	keep 64-bits counters. Thus all tools, that work with networking
1130	statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.)
1131
113220130618:
1133	Fix a bug that allowed a tracing process (e.g. gdb) to write
1134	to a memory-mapped file in the traced process's address space
1135	even if neither the traced process nor the tracing process had
1136	write access to that file.
1137
113820130615:
1139	CVS has been removed from the base system.  An exact copy
1140	of the code is available from the devel/cvs port.
1141
114220130613:
1143	Some people report the following error after the switch to bmake:
1144
1145		make: illegal option -- J
1146		usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable]
1147			...
1148		*** [buildworld] Error code 2
1149
1150	this likely due to an old instance of make in
1151	${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE})
1152	which src/Makefile will use that blindly, if it exists, so if
1153	you see the above error:
1154
1155		rm -rf `make -V MAKEPATH`
1156
1157	should resolve it.
1158
115920130516:
1160	Use bmake by default.
1161	Whereas before one could choose to build with bmake via
1162	-DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old
1163	make. The goal is to remove these knobs for 10-RELEASE.
1164
1165	It is worth noting that bmake (like gmake) treats the command
1166	line as the unit of failure, rather than statements within the
1167	command line.  Thus '(cd some/where && dosomething)' is safer
1168	than 'cd some/where; dosomething'. The '()' allows consistent
1169	behavior in parallel build.
1170
117120130429:
1172        Fix a bug that allows NFS clients to issue READDIR on files.
1173
117420130426:
1175	The WITHOUT_IDEA option has been removed because
1176	the IDEA patent expired.
1177
117820130426:
1179	The sysctl which controls TRIM support under ZFS has been renamed
1180	from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been
1181	enabled by default.
1182
118320130425:
1184	The mergemaster command now uses the default MAKEOBJDIRPREFIX
1185	rather than creating it's own in the temporary directory in
1186	order allow access to bootstrapped versions of tools such as
1187	install and mtree.  When upgrading from version of FreeBSD where
1188	the install command does not support -l, you will need to
1189	install a new mergemaster command if mergemaster -p is required.
1190	This can be accomplished with the command (cd src/usr.sbin/mergemaster
1191	&& make install).
1192
119320130404:
1194	Legacy ATA stack, disabled and replaced by new CAM-based one since
1195	FreeBSD 9.0, completely removed from the sources.  Kernel modules
1196	atadisk and atapi*, user-level tools atacontrol and burncd are
1197	removed.  Kernel option `options ATA_CAM` is now permanently enabled
1198	and removed.
1199
120020130319:
1201	SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2)
1202	and socketpair(2). Software, in particular Kerberos, may
1203	automatically detect and use these during building. The resulting
1204	binaries will not work on older kernels.
1205
120620130308:
1207	CTL_DISABLE has also been added to the sparc64 GENERIC (for further
1208	information, see the respective 20130304 entry).
1209
121020130304:
1211	Recent commits to callout(9) changed the size of struct callout,
1212	so the KBI is probably heavily disturbed. Also, some functions
1213	in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced
1214	by macros. Every kernel module using it won't load, so rebuild
1215	is requested.
1216
1217	The ctl device has been re-enabled in GENERIC for i386 and amd64,
1218	but does not initialize by default (because of the new CTL_DISABLE
1219	option) to save memory.  To re-enable it, remove the CTL_DISABLE
1220	option from the kernel config file or set kern.cam.ctl.disable=0
1221	in /boot/loader.conf.
1222
122320130301:
1224	The ctl device has been disabled in GENERIC for i386 and amd64.
1225	This was done due to the extra memory being allocated at system
1226	initialisation time by the ctl driver which was only used if
1227	a CAM target device was created.  This makes a FreeBSD system
1228	unusable on 128MB or less of RAM.
1229
123020130208:
1231	A new compression method (lz4) has been merged to -HEAD.  Please
1232	refer to zpool-features(7) for more information.
1233
1234	Please refer to the "ZFS notes" section of this file for information
1235	on upgrading boot ZFS pools.
1236
123720130129:
1238	A BSD-licensed patch(1) variant has been added and is installed
1239	as bsdpatch, being the GNU version the default patch.
1240	To inverse the logic and use the BSD-licensed one as default,
1241	while having the GNU version installed as gnupatch, rebuild
1242	and install world with the WITH_BSD_PATCH knob set.
1243
124420130121:
1245	Due to the use of the new -l option to install(1) during build
1246	and install, you must take care not to directly set the INSTALL
1247	make variable in your /etc/make.conf, /etc/src.conf, or on the
1248	command line.  If you wish to use the -C flag for all installs
1249	you may be able to add INSTALL+=-C to /etc/make.conf or
1250	/etc/src.conf.
1251
125220130118:
1253	The install(1) option -M has changed meaning and now takes an
1254	argument that is a file or path to append logs to.  In the
1255	unlikely event that -M was the last option on the command line
1256	and the command line contained at least two files and a target
1257	directory the first file will have logs appended to it.  The -M
1258	option served little practical purpose in the last decade so its
1259	use is expected to be extremely rare.
1260
126120121223:
1262	After switching to Clang as the default compiler some users of ZFS
1263	on i386 systems started to experience stack overflow kernel panics.
1264	Please consider using 'options KSTACK_PAGES=4' in such configurations.
1265
126620121222:
1267	GEOM_LABEL now mangles label names read from file system metadata.
1268	Mangling affect labels containing spaces, non-printable characters,
1269	'%' or '"'. Device names in /etc/fstab and other places may need to
1270	be updated.
1271
127220121217:
1273	By default, only the 10 most recent kernel dumps will be saved.  To
1274	restore the previous behaviour (no limit on the number of kernel dumps
1275	stored in the dump directory) add the following line to /etc/rc.conf:
1276
1277		savecore_flags=""
1278
127920121201:
1280	With the addition of auditdistd(8), a new auditdistd user is now
1281	required during installworld.  "mergemaster -p" can be used to
1282	add the user prior to installworld, as documented in the handbook.
1283
128420121117:
1285	The sin6_scope_id member variable in struct sockaddr_in6 is now
1286	filled by the kernel before passing the structure to the userland via
1287	sysctl or routing socket.  This means the KAME-specific embedded scope
1288	id in sin6_addr.s6_addr[2] is always cleared in userland application.
1289	This behavior can be controlled by net.inet6.ip6.deembed_scopeid.
1290	__FreeBSD_version is bumped to 1000025.
1291
129220121105:
1293	On i386 and amd64 systems WITH_CLANG_IS_CC is now the default.
1294	This means that the world and kernel will be compiled with clang
1295	and that clang will be installed as /usr/bin/cc, /usr/bin/c++,
1296	and /usr/bin/cpp.  To disable this behavior and revert to building
1297	with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions
1298	of current may need to bootstrap WITHOUT_CLANG first if the clang
1299	build fails (its compatibility window doesn't extend to the 9 stable
1300	branch point).
1301
130220121102:
1303	The IPFIREWALL_FORWARD kernel option has been removed. Its
1304	functionality now turned on by default.
1305
130620121023:
1307	The ZERO_COPY_SOCKET kernel option has been removed and
1308	split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP.
1309	NB: SOCKET_SEND_COW uses the VM page based copy-on-write
1310	mechanism which is not safe and may result in kernel crashes.
1311	NB: The SOCKET_RECV_PFLIP mechanism is useless as no current
1312	driver supports disposeable external page sized mbuf storage.
1313	Proper replacements for both zero-copy mechanisms are under
1314	consideration and will eventually lead to complete removal
1315	of the two kernel options.
1316
131720121023:
1318	The IPv4 network stack has been converted to network byte
1319	order. The following modules need to be recompiled together
1320	with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4),
1321	pf(4), ipfw(4), ng_ipfw(4), stf(4).
1322
132320121022:
1324	Support for non-MPSAFE filesystems was removed from VFS. The
1325	VFS_VERSION was bumped, all filesystem modules shall be
1326	recompiled.
1327
132820121018:
1329	All the non-MPSAFE filesystems have been disconnected from
1330	the build. The full list includes: codafs, hpfs, ntfs, nwfs,
1331	portalfs, smbfs, xfs.
1332
133320121016:
1334	The interface cloning API and ABI has changed. The following
1335	modules need to be recompiled together with kernel:
1336	ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4),
1337	vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4),
1338	faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4).
1339
134020121015:
1341	The sdhci driver was split in two parts: sdhci (generic SD Host
1342	Controller logic) and sdhci_pci (actual hardware driver).
1343	No kernel config modifications are required, but if you
1344	load sdhc as a module you must switch to sdhci_pci instead.
1345
134620121014:
1347	Import the FUSE kernel and userland support into base system.
1348
134920121013:
1350	The GNU sort(1) program has been removed since the BSD-licensed
1351	sort(1) has been the default for quite some time and no serious
1352	problems have been reported.  The corresponding WITH_GNU_SORT
1353	knob has also gone.
1354
135520121006:
1356	The pfil(9) API/ABI for AF_INET family has been changed. Packet
1357	filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled
1358	with new kernel.
1359
136020121001:
1361	The net80211(4) ABI has been changed to allow for improved driver
1362	PS-POLL and power-save support.  All wireless drivers need to be
1363	recompiled to work with the new kernel.
1364
136520120913:
1366	The random(4) support for the VIA hardware random number
1367	generator (`PADLOCK') is no longer enabled unconditionally.
1368	Add the padlock_rng device in the custom kernel config if
1369	needed.  The GENERIC kernels on i386 and amd64 do include the
1370	device, so the change only affects the custom kernel
1371	configurations.
1372
137320120908:
1374	The pf(4) packet filter ABI has been changed. pfctl(8) and
1375	snmp_pf module need to be recompiled to work with new kernel.
1376
137720120828:
1378	A new ZFS feature flag "com.delphix:empty_bpobj" has been merged
1379	to -HEAD. Pools that have empty_bpobj in active state can not be
1380	imported read-write with ZFS implementations that do not support
1381	this feature. For more information read the zpool-features(5)
1382	manual page.
1383
138420120727:
1385	The sparc64 ZFS loader has been changed to no longer try to auto-
1386	detect ZFS providers based on diskN aliases but now requires these
1387	to be explicitly listed in the OFW boot-device environment variable.
1388
138920120712:
1390	The OpenSSL has been upgraded to 1.0.1c.  Any binaries requiring
1391	libcrypto.so.6 or libssl.so.6 must be recompiled.  Also, there are
1392	configuration changes.  Make sure to merge /etc/ssl/openssl.cnf.
1393
139420120712:
1395	The following sysctls and tunables have been renamed for consistency
1396	with other variables:
1397	  kern.cam.da.da_send_ordered   -> kern.cam.da.send_ordered
1398	  kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered
1399
140020120628:
1401	The sort utility has been replaced with BSD sort.  For now, GNU sort
1402	is also available as "gnusort" or the default can be set back to
1403	GNU sort by setting WITH_GNU_SORT.  In this case, BSD sort will be
1404	installed as "bsdsort".
1405
140620120611:
1407	A new version of ZFS (pool version 5000) has been merged to -HEAD.
1408	Starting with this version the old system of ZFS pool versioning
1409	is superseded by "feature flags". This concept enables forward
1410	compatibility against certain future changes in functionality of ZFS
1411	pools. The first read-only compatible "feature flag" for ZFS pools
1412	is named "com.delphix:async_destroy". For more information
1413	read the new zpool-features(5) manual page.
1414	Please refer to the "ZFS notes" section of this file for information
1415	on upgrading boot ZFS pools.
1416
141720120417:
1418	The malloc(3) implementation embedded in libc now uses sources imported
1419	as contrib/jemalloc.  The most disruptive API change is to
1420	/etc/malloc.conf.  If your system has an old-style /etc/malloc.conf,
1421	delete it prior to installworld, and optionally re-create it using the
1422	new format after rebooting.  See malloc.conf(5) for details
1423	(specifically the TUNING section and the "opt.*" entries in the MALLCTL
1424	NAMESPACE section).
1425
142620120328:
1427	Big-endian MIPS TARGET_ARCH values no longer end in "eb".  mips64eb
1428	is now spelled mips64.  mipsn32eb is now spelled mipsn32.  mipseb is
1429	now spelled mips.  This is to aid compatibility with third-party
1430	software that expects this naming scheme in uname(3).  Little-endian
1431	settings are unchanged. If you are updating a big-endian mips64 machine
1432	from before this change, you may need to set MACHINE_ARCH=mips64 in
1433	your environment before the new build system will recognize your machine.
1434
143520120306:
1436	Disable by default the option VFS_ALLOW_NONMPSAFE for all supported
1437	platforms.
1438
143920120229:
1440	Now unix domain sockets behave "as expected" on	nullfs(5). Previously
1441	nullfs(5) did not pass through all behaviours to the underlying layer,
1442	as a result if we bound to a socket on the lower layer we could connect
1443	only to the lower path; if we bound to the upper layer we could connect
1444	only to	the upper path. The new behavior is one can connect to both the
1445	lower and the upper paths regardless what layer path one binds to.
1446
144720120211:
1448	The getifaddrs upgrade path broken with 20111215 has been restored.
1449	If you have upgraded in between 20111215 and 20120209 you need to
1450	recompile libc again with your kernel.  You still need to recompile
1451	world to be able to configure CARP but this restriction already
1452	comes from 20111215.
1453
145420120114:
1455	The set_rcvar() function has been removed from /etc/rc.subr.  All
1456	base and ports rc.d scripts have been updated, so if you have a
1457	port installed with a script in /usr/local/etc/rc.d you can either
1458	hand-edit the rcvar= line, or reinstall the port.
1459
1460	An easy way to handle the mass-update of /etc/rc.d:
1461	rm /etc/rc.d/* && mergemaster -i
1462
146320120109:
1464	panic(9) now stops other CPUs in the SMP systems, disables interrupts
1465	on the current CPU and prevents other threads from running.
1466	This behavior can be reverted using the kern.stop_scheduler_on_panic
1467	tunable/sysctl.
1468	The new behavior can be incompatible with kern.sync_on_panic.
1469
147020111215:
1471	The carp(4) facility has been changed significantly. Configuration
1472	of the CARP protocol via ifconfig(8) has changed, as well as format
1473	of CARP events submitted to devd(8) has changed. See manual pages
1474	for more information. The arpbalance feature of carp(4) is currently
1475	not supported anymore.
1476
1477	Size of struct in_aliasreq, struct in6_aliasreq has changed. User
1478	utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8),
1479	need to be recompiled.
1480
148120111122:
1482	The acpi_wmi(4) status device /dev/wmistat has been renamed to
1483	/dev/wmistat0.
1484
148520111108:
1486	The option VFS_ALLOW_NONMPSAFE option has been added in order to
1487	explicitely support non-MPSAFE filesystems.
1488	It is on by default for all supported platform at this present
1489	time.
1490
149120111101:
1492	The broken amd(4) driver has been replaced with esp(4) in the amd64,
1493	i386 and pc98 GENERIC kernel configuration files.
1494
149520110930:
1496	sysinstall has been removed
1497
149820110923:
1499	The stable/9 branch created in subversion.  This corresponds to the
1500	RELENG_9 branch in CVS.
1501
1502COMMON ITEMS:
1503
1504	General Notes
1505	-------------
1506	Avoid using make -j when upgrading.  While generally safe, there are
1507	sometimes problems using -j to upgrade.  If your upgrade fails with
1508	-j, please try again without -j.  From time to time in the past there
1509	have been problems using -j with buildworld and/or installworld.  This
1510	is especially true when upgrading between "distant" versions (eg one
1511	that cross a major release boundary or several minor releases, or when
1512	several months have passed on the -current branch).
1513
1514	Sometimes, obscure build problems are the result of environment
1515	poisoning.  This can happen because the make utility reads its
1516	environment when searching for values for global variables.  To run
1517	your build attempts in an "environmental clean room", prefix all make
1518	commands with 'env -i '.  See the env(1) manual page for more details.
1519
1520	When upgrading from one major version to another it is generally best to
1521	upgrade to the latest code in the currently installed branch first, then
1522	do an upgrade to the new branch. This is the best-tested upgrade path,
1523	and has the highest probability of being successful.  Please try this
1524	approach if you encounter problems with a major version upgrade.  Since
1525	the stable 4.x branch point, one has generally been able to upgade from
1526	anywhere in the most recent stable branch to head / current (or even the
1527	last couple of stable branches). See the top of this file when there's
1528	an exception.
1529
1530	When upgrading a live system, having a root shell around before
1531	installing anything can help undo problems. Not having a root shell
1532	around can lead to problems if pam has changed too much from your
1533	starting point to allow continued authentication after the upgrade.
1534
1535	This file should be read as a log of events. When a later event changes
1536	information of a prior event, the prior event should not be deleted.
1537	Instead, a pointer to the entry with the new information should be
1538	placed in the old entry. Readers of this file should also sanity check
1539	older entries before relying on them blindly. Authors of new entries
1540	should write them with this in mind.
1541
1542	ZFS notes
1543	---------
1544	When upgrading the boot ZFS pool to a new version, always follow
1545	these two steps:
1546
1547	1.) recompile and reinstall the ZFS boot loader and boot block
1548	(this is part of "make buildworld" and "make installworld")
1549
1550	2.) update the ZFS boot block on your boot drive
1551
1552	The following example updates the ZFS boot block on the first
1553	partition (freebsd-boot) of a GPT partitioned drive ada0:
1554	"gpart bootcode -p /boot/gptzfsboot -i 1 ada0"
1555
1556	Non-boot pools do not need these updates.
1557
1558	To build a kernel
1559	-----------------
1560	If you are updating from a prior version of FreeBSD (even one just
1561	a few days old), you should follow this procedure.  It is the most
1562	failsafe as it uses a /usr/obj tree with a fresh mini-buildworld,
1563
1564	make kernel-toolchain
1565	make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
1566	make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
1567
1568	To test a kernel once
1569	---------------------
1570	If you just want to boot a kernel once (because you are not sure
1571	if it works, or if you want to boot a known bad kernel to provide
1572	debugging information) run
1573	make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel
1574	nextboot -k testkernel
1575
1576	To just build a kernel when you know that it won't mess you up
1577	--------------------------------------------------------------
1578	This assumes you are already running a CURRENT system.  Replace
1579	${arch} with the architecture of your machine (e.g. "i386",
1580	"arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc).
1581
1582	cd src/sys/${arch}/conf
1583	config KERNEL_NAME_HERE
1584	cd ../compile/KERNEL_NAME_HERE
1585	make depend
1586	make
1587	make install
1588
1589	If this fails, go to the "To build a kernel" section.
1590
1591	To rebuild everything and install it on the current system.
1592	-----------------------------------------------------------
1593	# Note: sometimes if you are running current you gotta do more than
1594	# is listed here if you are upgrading from a really old current.
1595
1596	<make sure you have good level 0 dumps>
1597	make buildworld
1598	make kernel KERNCONF=YOUR_KERNEL_HERE
1599							[1]
1600	<reboot in single user>				[3]
1601	mergemaster -Fp					[5]
1602	make installworld
1603	mergemaster -Fi					[4]
1604	make delete-old					[6]
1605	<reboot>
1606
1607	To cross-install current onto a separate partition
1608	--------------------------------------------------
1609	# In this approach we use a separate partition to hold
1610	# current's root, 'usr', and 'var' directories.   A partition
1611	# holding "/", "/usr" and "/var" should be about 2GB in
1612	# size.
1613
1614	<make sure you have good level 0 dumps>
1615	<boot into -stable>
1616	make buildworld
1617	make buildkernel KERNCONF=YOUR_KERNEL_HERE
1618	<maybe newfs current's root partition>
1619	<mount current's root partition on directory ${CURRENT_ROOT}>
1620	make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC
1621	make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
1622	make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
1623	cp /etc/fstab ${CURRENT_ROOT}/etc/fstab 		   # if newfs'd
1624	<edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
1625	<reboot into current>
1626	<do a "native" rebuild/install as described in the previous section>
1627	<maybe install compatibility libraries from ports/misc/compat*>
1628	<reboot>
1629
1630
1631	To upgrade in-place from stable to current
1632	----------------------------------------------
1633	<make sure you have good level 0 dumps>
1634	make buildworld					[9]
1635	make kernel KERNCONF=YOUR_KERNEL_HERE		[8]
1636							[1]
1637	<reboot in single user>				[3]
1638	mergemaster -Fp					[5]
1639	make installworld
1640	mergemaster -Fi					[4]
1641	make delete-old					[6]
1642	<reboot>
1643
1644	Make sure that you've read the UPDATING file to understand the
1645	tweaks to various things you need.  At this point in the life
1646	cycle of current, things change often and you are on your own
1647	to cope.  The defaults can also change, so please read ALL of
1648	the UPDATING entries.
1649
1650	Also, if you are tracking -current, you must be subscribed to
1651	freebsd-current@freebsd.org.  Make sure that before you update
1652	your sources that you have read and understood all the recent
1653	messages there.  If in doubt, please track -stable which has
1654	much fewer pitfalls.
1655
1656	[1] If you have third party modules, such as vmware, you
1657	should disable them at this point so they don't crash your
1658	system on reboot.
1659
1660	[3] From the bootblocks, boot -s, and then do
1661		fsck -p
1662		mount -u /
1663		mount -a
1664		cd src
1665		adjkerntz -i		# if CMOS is wall time
1666	Also, when doing a major release upgrade, it is required that
1667	you boot into single user mode to do the installworld.
1668
1669	[4] Note: This step is non-optional.  Failure to do this step
1670	can result in a significant reduction in the functionality of the
1671	system.  Attempting to do it by hand is not recommended and those
1672	that pursue this avenue should read this file carefully, as well
1673	as the archives of freebsd-current and freebsd-hackers mailing lists
1674	for potential gotchas.  The -U option is also useful to consider.
1675	See mergemaster(8) for more information.
1676
1677	[5] Usually this step is a noop.  However, from time to time
1678	you may need to do this if you get unknown user in the following
1679	step.  It never hurts to do it all the time.  You may need to
1680	install a new mergemaster (cd src/usr.sbin/mergemaster && make
1681	install) after the buildworld before this step if you last updated
1682	from current before 20130425 or from -stable before 20130430.
1683
1684	[6] This only deletes old files and directories. Old libraries
1685	can be deleted by "make delete-old-libs", but you have to make
1686	sure that no program is using those libraries anymore.
1687
1688	[8] In order to have a kernel that can run the 4.x binaries needed to
1689	do an installworld, you must include the COMPAT_FREEBSD4 option in
1690	your kernel.  Failure to do so may leave you with a system that is
1691	hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is
1692	required to run the 5.x binaries on more recent kernels.  And so on
1693	for COMPAT_FREEBSD6 and COMPAT_FREEBSD7.
1694
1695	Make sure that you merge any new devices from GENERIC since the
1696	last time you updated your kernel config file.
1697
1698	[9] When checking out sources, you must include the -P flag to have
1699	cvs prune empty directories.
1700
1701	If CPUTYPE is defined in your /etc/make.conf, make sure to use the
1702	"?=" instead of the "=" assignment operator, so that buildworld can
1703	override the CPUTYPE if it needs to.
1704
1705	MAKEOBJDIRPREFIX must be defined in an environment variable, and
1706	not on the command line, or in /etc/make.conf.  buildworld will
1707	warn if it is improperly defined.

1710This file contains a list, in reverse chronological order, of major
1711breakages in tracking -current.  It is not guaranteed to be a complete
1712list of such breakages, and only contains entries since September 23, 2011.
1713If you need to see UPDATING entries from before that date, you will need
1714to fetch an UPDATING file from an older FreeBSD release.
