6a883e9d3SWarner Losh19990620:
7a883e9d3SWarner Losh	IPFW uid/gid-based filtering support has been committed. This
8a883e9d3SWarner Losh	breaks binary compatibility with previous copies of
9a883e9d3SWarner Losh	ipfw(8). Any utilities using the ioctl()s of ipfw (especially
10a883e9d3SWarner Losh	ipfw(8)) need to be recompiled with the newest headers
11a883e9d3SWarner Losh	installed.
12a883e9d3SWarner Losh
13a883e9d3SWarner Losh19990618:
14a883e9d3SWarner Losh	Inetd now wraps all stream-based services, including internals.
15a883e9d3SWarner Losh	Syslog "severity" options are honoured. Installed syslog.conf
16a883e9d3SWarner Losh	and hosts.allow should be checked.
17a883e9d3SWarner Losh
1807b72539SWarner Losh19990509:
1907b72539SWarner Losh	Most of the problems with newbus have been corrected, but
2007b72539SWarner Losh	it is still current and evolving.
2107b72539SWarner Losh
2207b72539SWarner Losh	libcam's ABI has changed.  You must recompile the world and
2307b72539SWarner Losh	any ports that use it.
2407b72539SWarner Losh
2509fcf3f9SWarner Losh19990427:
2609fcf3f9SWarner Losh	Massive changes to SMP went into the tree that should speed
2709fcf3f9SWarner Losh	things up.  However, if you experience problems with SMP
2809fcf3f9SWarner Losh	machines, you can back off to the PRE_SMP_VMSHARE tag in the
2909fcf3f9SWarner Losh	CVS repository (or run an MP kernel).
3009fcf3f9SWarner Losh
3109fcf3f9SWarner Losh19990420:
3209fcf3f9SWarner Losh	Pccardd and the pccard bus in general seem to be broken or
3309fcf3f9SWarner Losh	most people.  Soren has patches to make it better for some,
3409fcf3f9SWarner Losh	but not all people.  Work is underway to make it better for
3509fcf3f9SWarner Losh	all people.
3609fcf3f9SWarner Losh
37ea31d04dSWarner Losh19990416:
38ea31d04dSWarner Losh	new bus changes integrated into -current.  Many problems were
39ea31d04dSWarner Losh	initially reported, but most have been fixed.  You'll need a
40ea31d04dSWarner Losh	new config and to tweak your kernel config file the way that
41ea31d04dSWarner Losh	GENERIC was tweaked.  Keep a copy of your old kernel when
42ea31d04dSWarner Losh	upgrading in case your new kernel doesn't work (and report the
43ea31d04dSWarner Losh	breakage to current@freebsd.org).
44ea31d04dSWarner Losh
45ea31d04dSWarner Losh	As of 19990421 the remaining problems/quirks are
46ea31d04dSWarner Losh
47ea31d04dSWarner Losh	o sio no longer supports pnp nor pccard.  This will be corrected,
48ea31d04dSWarner Losh	  but the new pccard code needs to be completed.
49ea31d04dSWarner Losh	o Some of the sound drivers broke for some people.  It seems
50ea31d04dSWarner Losh	  inconsistant as to who/what/when/where things broke.
51ea31d04dSWarner Losh	o Duplicate device entries in your config do not work.  Previously
52ea31d04dSWarner Losh	  they were silently ignored.  psm0 seems to be the most common
53ea31d04dSWarner Losh	  duplicate choice, although some reports have come in from people
54ea31d04dSWarner Losh	  that wired their scsi disk entries.
55ea31d04dSWarner Losh	o You must move the keyboard and mouse attachments from the
56ea31d04dSWarner Losh	  isa bus to the atkbdc bus.  See GENERIC for details.
57ea31d04dSWarner Losh	o Machines with multiple host-pci bridges (Intel 450NX) will not
58ea31d04dSWarner Losh	  probe the second pci bus.
59ea31d04dSWarner Losh	o Some probe ordering may have changed, so device naming may change
60ea31d04dSWarner Losh	  with the new kernel.  If you have multiple devices, please double
61ea31d04dSWarner Losh	  check to make sure they didn't move.  This is especially true
62ea31d04dSWarner Losh	  for cards on different buses.
63ea31d04dSWarner Losh	o The bus attachment for vga0 is always isa0 and never pci0 when
64ea31d04dSWarner Losh	  it is in fact a pci card.  It is safe to ignore this.
65ea31d04dSWarner Losh	o The format of the boot messages has changed (and is not
66ea31d04dSWarner Losh	  guaranteed to be constant for a while) so you may see this
67ea31d04dSWarner Losh	  in some shell scripts that diff dmesg from day to day as well
68ea31d04dSWarner Losh	  as scripts that parse dmesg output.
69f8c77507SWarner Losh
70d24adca8SWarner Losh19990414:
71d24adca8SWarner Losh	cc -aout sometimes has problems compiling with -g, remove -g
72d24adca8SWarner Losh	from those compilation units affected until this is corrected.
73d24adca8SWarner Losh
74d24adca8SWarner Losh	cc -aout has problems with producing some threaded libraries,
75d24adca8SWarner Losh	so make world -DWANT_AOUT is not functional at this time.
76d24adca8SWarner Losh
77ea31d04dSWarner Losh	Since make world for a.out isn't functional, you cannot do
78ea31d04dSWarner Losh	make aout-to-elf from a pre-egcs a.out system.  To work around
79ea31d04dSWarner Losh	this problem, make aout-to-elf using 3.1-stable first (or a
80ea31d04dSWarner Losh	pre egcs -current) and then a simple make world will take you
81ea31d04dSWarner Losh	the rest of the way with a -current source base.
82ea31d04dSWarner Losh
83d5ca0636SWarner Losh19990413:
84d24adca8SWarner Losh	Make -j works again for make world.  As always, use it with
85d24adca8SWarner Losh	care, and be sure to try a make world w/o -j before reporting
86d24adca8SWarner Losh	problems (that is, know if the problem exists w/o -j before
87d24adca8SWarner Losh	reporting the problem with -j).
88d24adca8SWarner Losh
89d24adca8SWarner Losh19990413:
90d24adca8SWarner Losh	Note cc -aout, which had been broken since the conversion to
91ea31d04dSWarner Losh	egcs, now supposedly works.  If you have rebuilt things like
92d24adca8SWarner Losh	XFree86 a.out libraries, you should rebuild them again or
93ea31d04dSWarner Losh	progams that use them, including netscape, will fail to work.
94d5ca0636SWarner Losh
951f692d40SWarner Losh19990409:
961f692d40SWarner Losh	NOTE: New c++ compiler cannot be used with c++ binaries from
971f692d40SWarner Losh	the old compiler and vice versa.
981f692d40SWarner Losh
991f692d40SWarner Losh19990408:
10081725689SWarner Losh	In recent days egcs has been imported into the tree.  A number
10181725689SWarner Losh	of problems have been discussed in -current.  Here is a highlight
10281725689SWarner Losh	of a few of the more common ones.  With the exception of make
10381725689SWarner Losh	-j n, they have been claimed to have been fixed.
10481725689SWarner Losh
10581725689SWarner Losh	c++ is broken after make world: This is correct.  Because we
10681725689SWarner Losh	changed compilers two make worlds are necessary to get C++
10781725689SWarner Losh	working again.  The code generated by the old compiler and new
10881725689SWarner Losh	compiler are not compatible, so things wind up being
10981725689SWarner Losh	undefined.
11081725689SWarner Losh
11181725689SWarner Losh	cpp is broken in make world:  There was a window where cpp
11281725689SWarner Losh	would be built incorrectly.  The fix for this is
113420d4744SMasafumi Max NAKANE		cd src/gnu/usr.bin/cc
11481725689SWarner Losh		make clean
11581725689SWarner Losh		make all
11681725689SWarner Losh		make install
11781725689SWarner Losh	and this should correct your problems.  See the -current
11881725689SWarner Losh	archives for a version of this that does moer cleaning.
11981725689SWarner Losh
12081725689SWarner Losh	Make -j n doesn't work.  Work contiunes to make this work,
12181725689SWarner Losh	I've seen no reports of success as of April 7th.
12281725689SWarner Losh
123ff5e1f79SWarner Losh19990329:
124ff5e1f79SWarner Losh	Previously, one would define "NOAOUT" to keep from building
125ff5e1f79SWarner Losh	the legacy a.out bits.  Now one would define "WANT_AOUT" to
126ff5e1f79SWarner Losh	build them.
127ff5e1f79SWarner Losh
128fe9af953SWarner Losh19990316:
129fe9af953SWarner Losh	The name of the old wd.c and atapi.c based CDROM driver has
130fe9af953SWarner Losh	been changed back to wcd. So update your config file to use
131fe9af953SWarner Losh	"device wcd" instead of "device acd".
132fe9af953SWarner Losh
133fe9af953SWarner Losh19990314:
134fe9af953SWarner Losh	For those of you using the VN device as a loadable module,
135fe9af953SWarner Losh	please be aware that the new VN device has been committed to
136fe9af953SWarner Losh	-4.x and cannot yet be used as a loadable module.  This will
137fe9af953SWarner Losh	be fixed in the future.
138fe9af953SWarner Losh
139ce32355fSWarner Losh19990309:
140fe9af953SWarner Losh	New loader.rc mechanism.  Please see src/sys/boot/README for
141fe9af953SWarner Losh	details.
142ce32355fSWarner Losh
143f8c77507SWarner Losh19990225:
144f8c77507SWarner Losh	struct proc size changed.  Recompile kernel and the
145f8c77507SWarner Losh	usual suspects.  Make world if in doubt.
1461fc1a0dcSWarner Losh
1470edeb9e7SWarner Losh19990214:
1480edeb9e7SWarner Losh	The nlpt driver has changed names back to be the lpt driver.
1497dd38e55SWarner Losh	See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html
1507dd38e55SWarner Losh	for proper configuration details.
1510edeb9e7SWarner Losh
1521fc1a0dcSWarner Losh19990210:
1531fc1a0dcSWarner Losh	The 'lpt' driver is now obsolete.  Replace it with the 'nlpt'
1540edeb9e7SWarner Losh	driver and 'ppbus' controller combination.
15557199806SWarner Losh
1567dd38e55SWarner Losh19990209:
1577dd38e55SWarner Losh	New devstat API requires recompilation of libdevstat, systat,
1587dd38e55SWarner Losh	iostat, vmstat and rpc.rstatd.  A new kernel is also required.
1597dd38e55SWarner Losh	make world + building a kernel should do all of this.  Any
1607dd38e55SWarner Losh	ports that use devstat need to be recompiled as well.
1617dd38e55SWarner Losh
1629a3105eeSWarner Losh19990125:
1639a3105eeSWarner Losh	Linux threads options has gone away (they are now standard in
1649a3105eeSWarner Losh	the FreeBSD kernel).  A recompile of all libkvm using programs
1659a3105eeSWarner Losh	is in order (or better yet a make world).
1669a3105eeSWarner Losh
1679a3105eeSWarner Losh19990122:
1689a3105eeSWarner Losh	On or about this date there was a small window when the boot
1699a3105eeSWarner Losh	blocks had some minor problems which seemed to force one to
1709a3105eeSWarner Losh	edit /etc/fstab.  This has been corrected, if you are seeing this
1719a3105eeSWarner Losh	problem, please rebuild and reinstall your boot blocks.
1729a3105eeSWarner Losh
1739a3105eeSWarner Losh19990121:
1748cd37f69SWarner Losh	Vinum has changed.  The "vinum read" command has changed.  For
1758cd37f69SWarner Losh	updates, please see
1763652181cSWarner Losh
1778cd37f69SWarner Loshhttp://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current
1783652181cSWarner Losh
1798cd37f69SWarner Losh	for details.
1808cd37f69SWarner Losh
1818cd37f69SWarner Losh	Matt Dillon committed a boatload of VM changes, for
1828cd37f69SWarner Losh	information please see
1833652181cSWarner Losh
1848cd37f69SWarner Loshhttp://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current
1858cd37f69SWarner Losh	or
1868cd37f69SWarner Loshhttp://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current
1873652181cSWarner Losh
1888cd37f69SWarner Losh	for details.  These changes will likely not impact anybody,
1898cd37f69SWarner Losh	but large chagnes to the VM need at least a heads up.
1908cd37f69SWarner Losh
1918cd37f69SWarner Losh19990120:
1928cd37f69SWarner Losh	Stable branch created.  You might want to consider using this
1938cd37f69SWarner Losh	branch.  It is tagged with RELENG_3.
1948cd37f69SWarner Losh
195ad56ea87SWarner Losh19990119:
196ad56ea87SWarner Losh	More work on the syscons driver has been committed.  Since
197ad56ea87SWarner Losh	files moved around, you will need to reconfigure your kernel,
198ad56ea87SWarner Losh	and make clean; make depend before rebuilding the kernel.  No
199ad56ea87SWarner Losh	config file changes are needed.
200ad56ea87SWarner Losh
20157199806SWarner Losh19990111:
202a85c0f55SWarner Losh	New keyboard and video card drivers are introduced as the first
203a85c0f55SWarner Losh	stage of console driver reorganization.  You are required to
204a85c0f55SWarner Losh	update the kernel configuration file and rebuild the kernel.
205a85c0f55SWarner Losh	kbdcontrol, vidcontrol, and screen savers also need recompilation.
206a85c0f55SWarner Losh	The instruction can be found in
20757199806SWarner Losh
2087dafbc29SWarner Losh		http://www.freebsd.org/~yokota/sc_update.txt
20957199806SWarner Losh
210a85c0f55SWarner Losh	It has notes on splash screen too.
21157199806SWarner Losh
21257199806SWarner Losh19990106:
2139857e582SWarner Losh	Robert Nordier was kind enough to make this page to enable people to
214db23c94fSWarner Losh	install the new bootblocks:
21557199806SWarner Losh
2167dafbc29SWarner Losh		http://www.freebsd.org/~rnordier/boot.txt
21757199806SWarner Losh
2189ba54ae0SWarner Losh	When updating to ELF, make sure that you have updated your
2199ba54ae0SWarner Losh	/etc/rc files which have different ldconfig invocations for
2209ba54ae0SWarner Losh	elf and aout.  Otherwise things like X will stop working with
2219857e582SWarner Losh	messages about being unable to find library files.  The
2229857e582SWarner Losh	mergemaster utility in ports/sysutils/mergemaster helps to
2239857e582SWarner Losh	keep critical files like this in sync, and its use is
2249857e582SWarner Losh	recommended.
22557199806SWarner Losh
22657199806SWarner Losh19990104:
2272c558794SWarner Losh	Information about ELF day (see 19981230) can be found in
22857199806SWarner Losh
2297dafbc29SWarner Losh		http://www.freebsd.org/~peter/elfday.html
23057199806SWarner Losh
2312c558794SWarner Losh	about the upcoming change, its motivations and instructions
2322c558794SWarner Losh	for doing the upgrade.
23357199806SWarner Losh
23457199806SWarner Losh19981230:
235d5513f53SWarner Losh	You should install new bootblocks now.  The ELF kernel will
236e363c17bSWarner Losh	become default soon.  In addition, you'll need to upgrade
237e363c17bSWarner Losh	your userland programs to ELF before then as well.  Use
238e363c17bSWarner Losh	make aout-to-elf to upgrade your userland programs (old
239e363c17bSWarner Losh	a.out programs in, for example, /usr/local/bin will
240e363c17bSWarner Losh	continue to work, even after the upgrade).  See src/Makefile
241e363c17bSWarner Losh	for more details.
24257199806SWarner Losh
24357199806SWarner Losh19981224:
244355edc3eSWarner Losh	The old wcd driver has been deleted from the kernel.  The
245355edc3eSWarner Losh	driver that replaces it is named acd.  You'll need to change
246355edc3eSWarner Losh	this in your configuration files.
24757199806SWarner Losh
248355edc3eSWarner Losh	Failure to do this will result in "ATAPI CD-ROMs not
249355edc3eSWarner Losh	configured" at boot time.
25057199806SWarner Losh
251355edc3eSWarner Losh	The floppy tape driver (ft) has been removed from the kernel,
252355edc3eSWarner Losh	with no replacement driver.
25357199806SWarner Losh
25457199806SWarner Losh19981202:
255ab308df6SWarner Losh	New groups from 19981201 commented out of mtree, so they
256ab308df6SWarner Losh	aren't strictly needed, but still a good idea to have.
25757199806SWarner Losh
25857199806SWarner Losh19981201:
259ab308df6SWarner Losh	New user/group added: bind.  From src/etc/master.passwd and

26757199806SWarner Losh
26857199806SWarner Losh19981118:
26953dfde79SWarner Losh	PAM integrated into the tree.   Requires new /etc/pam.conf file
27053dfde79SWarner Losh	to silence warnings from authentication programs (login, etc).
27153dfde79SWarner Losh	See src/etc/pam.conf for a sample.
