1Updating Information for FreeBSD current users. 2 3This file is maintained and copyrighted by M. Warner Losh <imp@freebsd.org>. 4See end of file for further details. For commonly done items, please see the 5COMMON ITEMS: section later in the file. These instructions assume that you 6basically know what you are doing. If not, then please consult the FreeBSD 7handbook: 8 9 http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before running portupgrade. 13 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 from 17older version of current across the gcc/clang cutover is a bit fragile. 18 19NOTE TO PEOPLE WHO THINK THAT FreeBSD 11.x IS SLOW: 20 FreeBSD 11.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 3420150604: 35 Generation of legacy formatted entries have been disabled by default 36 in pwd_mkdb(8), as all base system consumers of the legacy formatted 37 entries were converted to use the new format by default when the new, 38 machine independent format have been added and supported since FreeBSD 39 5.x. 40 41 Please see the pwd_mkdb(8) manual page for further details. 42 4320150525: 44 Clang and llvm have been upgraded to 3.6.1 release. Please see the 45 20141231 entry below for information about prerequisites and upgrading, 46 if you are not already using 3.5.0 or higher. 47 4820150521: 49 TI platform code switched to using vendor DTS files and this update 50 may break existing systems running on Beaglebone, Beaglebone Black, 51 and Pandaboard: 52 53 - dtb files should be regenerated/reinstalled. Filenames are the 54 same but content is different now 55 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 56 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 57 addressing scheme is now pin 25 on /dev/gpioc3. 58 - Pandaboard: /etc/ttys should be updated, serial console device is 59 now /dev/ttyu2, not /dev/ttyu0 60 6120150501: 62 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 63 If you need the GNU extension from groff soelim(1), install groff 64 from package: pkg install groff, or via ports: textproc/groff. 65 6620150423: 67 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 68 defined in symlink(7); previously symlinks were silently ignored. 69 7020150415: 71 The const qualifier has been removed from iconv(3) to comply with 72 POSIX. The ports tree is aware of this from r384038 onwards. 73 7420150416: 75 Libraries specified by LIBADD in Makefiles must have a corresponding 76 DPADD_<lib> variable to ensure correct dependencies. This is now 77 enforced in src.libnames.mk. 78 7920150324: 80 From legacy ata(4) driver was removed support for SATA controllers 81 supported by more functional drivers ahci(4), siis(4) and mvs(4). 82 Kernel modules ataahci and ataadaptec were removed completely, 83 replaced by ahci and mvs modules respectively. 84 8520150315: 86 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 87 the 20141231 entry below for information about prerequisites and 88 upgrading, if you are not already using 3.5.0 or higher. 89 9020150307: 91 The 32-bit PowerPC kernel has been changed to a position-independent 92 executable. This can only be booted with a version of loader(8) 93 newer than January 31, 2015, so make sure to update both world and 94 kernel before rebooting. 95 9620150217: 97 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 98 but before r278950, the RNG was not seeded properly. Immediately 99 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 100 ssh keys or openssl keys) that were generated w/ a kernel from that 101 range. This does not affect programs that directly used /dev/random 102 or /dev/urandom. All userland uses of arc4random(3) are affected. 103 10420150210: 105 The autofs(4) ABI was changed in order to restore binary compatibility 106 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 107 with the new kernel. 108 10920150131: 110 The powerpc64 kernel has been changed to a position-independent 111 executable. This can only be booted with a new version of loader(8), 112 so make sure to update both world and kernel before rebooting. 113 11420150118: 115 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 116 only release, no new features have been added. Please see the 20141231 117 entry below for information about prerequisites and upgrading, if you 118 are not already using 3.5.0. 119 12020150107: 121 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 122 taken from the ELF Tool Chain project rather than GNU binutils. They 123 should be drop-in replacements, with the addition of arm64 support. 124 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 125 binutils tools, if necessary. 126 12720150105: 128 The default Unbound configuration now enables remote control 129 using a local socket. Users who have already enabled the 130 local_unbound service should regenerate their configuration 131 by running "service local_unbound setup" as root. 132 13320150102: 134 The GNU texinfo and GNU info pages have been removed. 135 To be able to view GNU info pages please install texinfo from ports. 136 13720141231: 138 Clang, llvm and lldb have been upgraded to 3.5.0 release. 139 140 As of this release, a prerequisite for building clang, llvm and lldb is 141 a C++11 capable compiler and C++11 standard library. This means that to 142 be able to successfully build the cross-tools stage of buildworld, with 143 clang as the bootstrap compiler, your system compiler or cross compiler 144 should either be clang 3.3 or later, or gcc 4.8 or later, and your 145 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 146 later. 147 148 On any standard FreeBSD 10.x or 11.x installation, where clang and 149 libc++ are on by default (that is, on x86 or arm), this should work out 150 of the box. 151 152 On 9.x installations where clang is enabled by default, e.g. on x86 and 153 powerpc, libc++ will not be enabled by default, so libc++ should be 154 built (with clang) and installed first. If both clang and libc++ are 155 missing, build clang first, then use it to build libc++. 156 157 On 8.x and earlier installations, upgrade to 9.x first, and then follow 158 the instructions for 9.x above. 159 160 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 161 default, and do not build clang. 162 163 Many embedded systems are resource constrained, and will not be able to 164 build clang in a reasonable time, or in some cases at all. In those 165 cases, cross building bootable systems on amd64 is a workaround. 166 167 This new version of clang introduces a number of new warnings, of which 168 the following are most likely to appear: 169 170 -Wabsolute-value 171 172 This warns in two cases, for both C and C++: 173 * When the code is trying to take the absolute value of an unsigned 174 quantity, which is effectively a no-op, and almost never what was 175 intended. The code should be fixed, if at all possible. If you are 176 sure that the unsigned quantity can be safely cast to signed, without 177 loss of information or undefined behavior, you can add an explicit 178 cast, or disable the warning. 179 180 * When the code is trying to take an absolute value, but the called 181 abs() variant is for the wrong type, which can lead to truncation. 182 If you want to disable the warning instead of fixing the code, please 183 make sure that truncation will not occur, or it might lead to unwanted 184 side-effects. 185 186 -Wtautological-undefined-compare and 187 -Wundefined-bool-conversion 188 189 These warn when C++ code is trying to compare 'this' against NULL, while 190 'this' should never be NULL in well-defined C++ code. However, there is 191 some legacy (pre C++11) code out there, which actively abuses this 192 feature, which was less strictly defined in previous C++ versions. 193 194 Squid and openjdk do this, for example. The warning can be turned off 195 for C++98 and earlier, but compiling the code in C++11 mode might result 196 in unexpected behavior; for example, the parts of the program that are 197 unreachable could be optimized away. 198 19920141222: 200 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 201 kernel sources have been removed. The .h files remain, since some 202 utilities include them. This will need to be fixed later. 203 If "mount -t oldnfs ..." is attempted, it will fail. 204 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 205 the utilities will report errors. 206 20720141121: 208 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 209 directories to top level SUBDIR variable when their parent 210 directory is included in LOCAL_DIRS. Users with build systems with 211 such hierarchies and without SUBDIR entries in the parent 212 directory Makefiles should add them or add the directories to 213 LOCAL_DIRS. 214 21520141109: 216 faith(4) and faithd(8) have been removed from the base system. Faith 217 has been obsolete for a very long time. 218 21920141104: 220 vt(4), the new console driver, is enabled by default. It brings 221 support for Unicode and double-width characters, as well as 222 support for UEFI and integration with the KMS kernel video 223 drivers. 224 225 You may need to update your console settings in /etc/rc.conf, 226 most probably the keymap. During boot, /etc/rc.d/syscons will 227 indicate what you need to do. 228 229 vt(4) still has issues and lacks some features compared to 230 syscons(4). See the wiki for up-to-date information: 231 https://wiki.freebsd.org/Newcons 232 233 If you want to keep using syscons(4), you can do so by adding 234 the following line to /boot/loader.conf: 235 kern.vty=sc 236 23720141102: 238 pjdfstest has been integrated into kyua as an opt-in test suite. 239 Please see share/doc/pjdfstest/README for more details on how to 240 execute it. 241 24220141009: 243 gperf has been removed from the base system for architectures 244 that use clang. Ports that require gperf will obtain it from the 245 devel/gperf port. 246 24720140923: 248 pjdfstest has been moved from tools/regression/pjdfstest to 249 contrib/pjdfstest . 250 25120140922: 252 At svn r271982, The default linux compat kernel ABI has been adjusted 253 to 2.6.18 in support of the linux-c6 compat ports infrastructure 254 update. If you wish to continue using the linux-f10 compat ports, 255 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 256 encouraged to update their linux-compat packages to linux-c6 during 257 their next update cycle. 258 25920140729: 260 The ofwfb driver, used to provide a graphics console on PowerPC when 261 using vt(4), no longer allows mmap() of all physical memory. This 262 will prevent Xorg on PowerPC with some ATI graphics cards from 263 initializing properly unless x11-servers/xorg-server is updated to 264 1.12.4_8 or newer. 265 26620140723: 267 The xdev targets have been converted to using TARGET and 268 TARGET_ARCH instead of XDEV and XDEV_ARCH. 269 27020140719: 271 The default unbound configuration has been modified to address 272 issues with reverse lookups on networks that use private 273 address ranges. If you use the local_unbound service, run 274 "service local_unbound setup" as root to regenerate your 275 configuration, then "service local_unbound reload" to load the 276 new configuration. 277 27820140709: 279 The GNU texinfo and GNU info pages are not built and installed 280 anymore, WITH_INFO knob has been added to allow to built and install 281 them again. 282 UPDATE: see 20150102 entry on texinfo's removal 283 28420140708: 285 The GNU readline library is now an INTERNALLIB - that is, it is 286 statically linked into consumers (GDB and variants) in the base 287 system, and the shared library is no longer installed. The 288 devel/readline port is available for third party software that 289 requires readline. 290 29120140702: 292 The Itanium architecture (ia64) has been removed from the list of 293 known architectures. This is the first step in the removal of the 294 architecture. 295 29620140701: 297 Commit r268115 has added NFSv4.1 server support, merged from 298 projects/nfsv4.1-server. Since this includes changes to the 299 internal interfaces between the NFS related modules, a full 300 build of the kernel and modules will be necessary. 301 __FreeBSD_version has been bumped. 302 30320140629: 304 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 305 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 306 which differs from the behaviour controlled by this knob.) 307 30820140619: 309 Maximal length of the serial number in CTL was increased from 16 to 310 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 311 and ctld, need to be rebuilt to work with a new kernel. 312 31320140606: 314 The libatf-c and libatf-c++ major versions were downgraded to 0 and 315 1 respectively to match the upstream numbers. They were out of 316 sync because, when they were originally added to FreeBSD, the 317 upstream versions were not respected. These libraries are private 318 and not yet built by default, so renumbering them should be a 319 non-issue. However, unclean source trees will yield broken test 320 programs once the operator executes "make delete-old-libs" after a 321 "make installworld". 322 323 Additionally, the atf-sh binary was made private by moving it into 324 /usr/libexec/. Already-built shell test programs will keep the 325 path to the old binary so they will break after "make delete-old" 326 is run. 327 328 If you are using WITH_TESTS=yes (not the default), wipe the object 329 tree and rebuild from scratch to prevent spurious test failures. 330 This is only needed once: the misnumbered libraries and misplaced 331 binaries have been added to OptionalObsoleteFiles.inc so they will 332 be removed during a clean upgrade. 333 33420140512: 335 Clang and llvm have been upgraded to 3.4.1 release. 336 33720140508: 338 We bogusly installed src.opts.mk in /usr/share/mk. This file should 339 be removed to avoid issues in the future (and has been added to 340 ObsoleteFiles.inc). 341 34220140505: 343 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 344 past, it affected all builds that used the bsd.*.mk files. The old 345 behavior was a bug, but people may have relied upon it. To get this 346 behavior back, you can .include /etc/src.conf from /etc/make.conf 347 (which is still global and isn't changed). This also changes the 348 behavior of incremental builds inside the tree of individual 349 directories. Set MAKESYSPATH to ".../share/mk" to do that. 350 Although this has survived make universe and some upgrade scenarios, 351 other upgrade scenarios may have broken. At least one form of 352 temporary breakage was fixed with MAKESYSPATH settings for buildworld 353 as well... In cases where MAKESYSPATH isn't working with this 354 setting, you'll need to set it to the full path to your tree. 355 356 One side effect of all this cleaning up is that bsd.compiler.mk 357 is no longer implicitly included by bsd.own.mk. If you wish to 358 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 359 as well. 360 36120140430: 362 The lindev device has been removed since /dev/full has been made a 363 standard device. __FreeBSD_version has been bumped. 364 36520140424: 366 The knob WITHOUT_VI was added to the base system, which controls 367 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 368 in order to reorder files share/termcap and didn't build ex(1) as a 369 build tool, so building/installing with WITH_VI is highly advised for 370 build hosts for older releases. 371 372 This issue has been fixed in stable/9 and stable/10 in r277022 and 373 r276991, respectively. 374 37520140418: 376 The YES_HESIOD knob has been removed. It has been obsolete for 377 a decade. Please move to using WITH_HESIOD instead or your builds 378 will silently lack HESIOD. 379 38020140405: 381 The uart(4) driver has been changed with respect to its handling 382 of the low-level console. Previously the uart(4) driver prevented 383 any process from changing the baudrate or the CLOCAL and HUPCL 384 control flags. By removing the restrictions, operators can make 385 changes to the serial console port without having to reboot. 386 However, when getty(8) is started on the serial device that is 387 associated with the low-level console, a misconfigured terminal 388 line in /etc/ttys will now have a real impact. 389 Before upgrading the kernel, make sure that /etc/ttys has the 390 serial console device configured as 3wire without baudrate to 391 preserve the previous behaviour. E.g: 392 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 393 39420140306: 395 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 396 to improve performance. To re-enable it, if needed, run rpcbind 397 with command line option -W. 398 39920140226: 400 Switched back to the GPL dtc compiler due to updates in the upstream 401 dts files not being supported by the BSDL dtc compiler. You will need 402 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 403 may result while building dtb files during a kernel build if you fail 404 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 405 40620140216: 407 Clang and llvm have been upgraded to 3.4 release. 408 40920140216: 410 The nve(4) driver has been removed. Please use the nfe(4) driver 411 for NVIDIA nForce MCP Ethernet adapters instead. 412 41320140212: 414 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 415 This could cause certain C++ applications using shared libraries built 416 against the previous version of libc++ to crash. The incompatibility 417 has now been fixed, but any C++ applications or shared libraries built 418 between r261283 and r261801 should be recompiled. 419 42020140204: 421 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 422 capability mode support. Please note that enabling the feature in 423 kernel is still highly recommended. 424 42520140131: 426 OpenSSH is now built with sandbox support, and will use sandbox as 427 the default privilege separation method. This requires Capsicum 428 capability mode support in kernel. 429 43020140128: 431 The libelf and libdwarf libraries have been updated to newer 432 versions from upstream. Shared library version numbers for 433 these two libraries were bumped. Any ports or binaries 434 requiring these two libraries should be recompiled. 435 __FreeBSD_version is bumped to 1100006. 436 43720140110: 438 If a Makefile in a tests/ directory was auto-generating a Kyuafile 439 instead of providing an explicit one, this would prevent such 440 Makefile from providing its own Kyuafile in the future during 441 NO_CLEAN builds. This has been fixed in the Makefiles but manual 442 intervention is needed to clean an objdir if you use NO_CLEAN: 443 # find /usr/obj -name Kyuafile | xargs rm -f 444 44520131213: 446 The behavior of gss_pseudo_random() for the krb5 mechanism 447 has changed, for applications requesting a longer random string 448 than produced by the underlying enctype's pseudo-random() function. 449 In particular, the random string produced from a session key of 450 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 451 be different at the 17th octet and later, after this change. 452 The counter used in the PRF+ construction is now encoded as a 453 big-endian integer in accordance with RFC 4402. 454 __FreeBSD_version is bumped to 1100004. 455 45620131108: 457 The WITHOUT_ATF build knob has been removed and its functionality 458 has been subsumed into the more generic WITHOUT_TESTS. If you were 459 using the former to disable the build of the ATF libraries, you 460 should change your settings to use the latter. 461 46220131025: 463 The default version of mtree is nmtree which is obtained from 464 NetBSD. The output is generally the same, but may vary 465 slightly. If you found you need identical output adding 466 "-F freebsd9" to the command line should do the trick. For the 467 time being, the old mtree is available as fmtree. 468 46920131014: 470 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 471 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 472 1.1.4_8 and verify bsdyml not linked in, before running "make 473 delete-old-libs": 474 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 475 or 476 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 477 47820131010: 479 The rc.d/jail script has been updated to support jail(8) 480 configuration file. The "jail_<jname>_*" rc.conf(5) variables 481 for per-jail configuration are automatically converted to 482 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 483 This is transparently backward compatible. See below about some 484 incompatibilities and rc.conf(5) manual page for more details. 485 486 These variables are now deprecated in favor of jail(8) configuration 487 file. One can use "rc.d/jail config <jname>" command to generate 488 a jail(8) configuration file in /var/run/jail.<jname>.conf without 489 running the jail(8) utility. The default pathname of the 490 configuration file is /etc/jail.conf and can be specified by 491 using $jail_conf or $jail_<jname>_conf variables. 492 493 Please note that jail_devfs_ruleset accepts an integer at 494 this moment. Please consider to rewrite the ruleset name 495 with an integer. 496 49720130930: 498 BIND has been removed from the base system. If all you need 499 is a local resolver, simply enable and start the local_unbound 500 service instead. Otherwise, several versions of BIND are 501 available in the ports tree. The dns/bind99 port is one example. 502 503 With this change, nslookup(1) and dig(1) are no longer in the base 504 system. Users should instead use host(1) and drill(1) which are 505 in the base system. Alternatively, nslookup and dig can 506 be obtained by installing the dns/bind-tools port. 507 50820130916: 509 With the addition of unbound(8), a new unbound user is now 510 required during installworld. "mergemaster -p" can be used to 511 add the user prior to installworld, as documented in the handbook. 512 51320130911: 514 OpenSSH is now built with DNSSEC support, and will by default 515 silently trust signed SSHFP records. This can be controlled with 516 the VerifyHostKeyDNS client configuration setting. DNSSEC support 517 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 518 51920130906: 520 The GNU Compiler Collection and C++ standard library (libstdc++) 521 are no longer built by default on platforms where clang is the system 522 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 523 options in src.conf. 524 52520130905: 526 The PROCDESC kernel option is now part of the GENERIC kernel 527 configuration and is required for the rwhod(8) to work. 528 If you are using custom kernel configuration, you should include 529 'options PROCDESC'. 530 53120130905: 532 The API and ABI related to the Capsicum framework was modified 533 in backward incompatible way. The userland libraries and programs 534 have to be recompiled to work with the new kernel. This includes the 535 following libraries and programs, but the whole buildworld is 536 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 537 kdump, procstat, rwho, rwhod, uniq. 538 53920130903: 540 AES-NI intrinsic support has been added to gcc. The AES-NI module 541 has been updated to use this support. A new gcc is required to build 542 the aesni module on both i386 and amd64. 543 54420130821: 545 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 546 Thus "device padlock_rng" and "device rdrand_rng" should be 547 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 548 54920130813: 550 WITH_ICONV has been split into two feature sets. WITH_ICONV now 551 enables just the iconv* functionality and is now on by default. 552 WITH_LIBICONV_COMPAT enables the libiconv api and link time 553 compatability. Set WITHOUT_ICONV to build the old way. 554 If you have been using WITH_ICONV before, you will very likely 555 need to turn on WITH_LIBICONV_COMPAT. 556 55720130806: 558 INVARIANTS option now enables DEBUG for code with OpenSolaris and 559 Illumos origin, including ZFS. If you have INVARIANTS in your 560 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 561 explicitly. 562 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 563 locks if WITNESS option was set. Because that generated a lot of 564 witness(9) reports and all of them were believed to be false 565 positives, this is no longer done. New option OPENSOLARIS_WITNESS 566 can be used to achieve the previous behavior. 567 56820130806: 569 Timer values in IPv6 data structures now use time_uptime instead 570 of time_second. Although this is not a user-visible functional 571 change, userland utilities which directly use them---ndp(8), 572 rtadvd(8), and rtsold(8) in the base system---need to be updated 573 to r253970 or later. 574 57520130802: 576 find -delete can now delete the pathnames given as arguments, 577 instead of only files found below them or if the pathname did 578 not contain any slashes. Formerly, the following error message 579 would result: 580 581 find: -delete: <path>: relative path potentially not safe 582 583 Deleting the pathnames given as arguments can be prevented 584 without error messages using -mindepth 1 or by changing 585 directory and passing "." as argument to find. This works in the 586 old as well as the new version of find. 587 58820130726: 589 Behavior of devfs rules path matching has been changed. 590 Pattern is now always matched against fully qualified devfs 591 path and slash characters must be explicitly matched by 592 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 593 subdirectories must be reviewed. 594 59520130716: 596 The default ARM ABI has changed to the ARM EABI. The old ABI is 597 incompatible with the ARM EABI and all programs and modules will 598 need to be rebuilt to work with a new kernel. 599 600 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 601 602 NOTE: Support for the old ABI will be removed in the future and 603 users are advised to upgrade. 604 60520130709: 606 pkg_install has been disconnected from the build if you really need it 607 you should add WITH_PKGTOOLS in your src.conf(5). 608 60920130709: 610 Most of network statistics structures were changed to be able 611 keep 64-bits counters. Thus all tools, that work with networking 612 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 613 61420130629: 615 Fix targets that run multiple make's to use && rather than ; 616 so that subsequent steps depend on success of previous. 617 618 NOTE: if building 'universe' with -j* on stable/8 or stable/9 619 it would be better to start the build using bmake, to avoid 620 overloading the machine. 621 62220130618: 623 Fix a bug that allowed a tracing process (e.g. gdb) to write 624 to a memory-mapped file in the traced process's address space 625 even if neither the traced process nor the tracing process had 626 write access to that file. 627 62820130615: 629 CVS has been removed from the base system. An exact copy 630 of the code is available from the devel/cvs port. 631 63220130613: 633 Some people report the following error after the switch to bmake: 634 635 make: illegal option -- J 636 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 637 ... 638 *** [buildworld] Error code 2 639 640 this likely due to an old instance of make in 641 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 642 which src/Makefile will use that blindly, if it exists, so if 643 you see the above error: 644 645 rm -rf `make -V MAKEPATH` 646 647 should resolve it. 648 64920130516: 650 Use bmake by default. 651 Whereas before one could choose to build with bmake via 652 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 653 make. The goal is to remove these knobs for 10-RELEASE. 654 655 It is worth noting that bmake (like gmake) treats the command 656 line as the unit of failure, rather than statements within the 657 command line. Thus '(cd some/where && dosomething)' is safer 658 than 'cd some/where; dosomething'. The '()' allows consistent 659 behavior in parallel build. 660 66120130429: 662 Fix a bug that allows NFS clients to issue READDIR on files. 663 66420130426: 665 The WITHOUT_IDEA option has been removed because 666 the IDEA patent expired. 667 66820130426: 669 The sysctl which controls TRIM support under ZFS has been renamed 670 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 671 enabled by default. 672 67320130425: 674 The mergemaster command now uses the default MAKEOBJDIRPREFIX 675 rather than creating it's own in the temporary directory in 676 order allow access to bootstrapped versions of tools such as 677 install and mtree. When upgrading from version of FreeBSD where 678 the install command does not support -l, you will need to 679 install a new mergemaster command if mergemaster -p is required. 680 This can be accomplished with the command (cd src/usr.sbin/mergemaster 681 && make install). 682 68320130404: 684 Legacy ATA stack, disabled and replaced by new CAM-based one since 685 FreeBSD 9.0, completely removed from the sources. Kernel modules 686 atadisk and atapi*, user-level tools atacontrol and burncd are 687 removed. Kernel option `options ATA_CAM` is now permanently enabled 688 and removed. 689 69020130319: 691 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 692 and socketpair(2). Software, in particular Kerberos, may 693 automatically detect and use these during building. The resulting 694 binaries will not work on older kernels. 695 69620130308: 697 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 698 information, see the respective 20130304 entry). 699 70020130304: 701 Recent commits to callout(9) changed the size of struct callout, 702 so the KBI is probably heavily disturbed. Also, some functions 703 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 704 by macros. Every kernel module using it won't load, so rebuild 705 is requested. 706 707 The ctl device has been re-enabled in GENERIC for i386 and amd64, 708 but does not initialize by default (because of the new CTL_DISABLE 709 option) to save memory. To re-enable it, remove the CTL_DISABLE 710 option from the kernel config file or set kern.cam.ctl.disable=0 711 in /boot/loader.conf. 712 71320130301: 714 The ctl device has been disabled in GENERIC for i386 and amd64. 715 This was done due to the extra memory being allocated at system 716 initialisation time by the ctl driver which was only used if 717 a CAM target device was created. This makes a FreeBSD system 718 unusable on 128MB or less of RAM. 719 72020130208: 721 A new compression method (lz4) has been merged to -HEAD. Please 722 refer to zpool-features(7) for more information. 723 724 Please refer to the "ZFS notes" section of this file for information 725 on upgrading boot ZFS pools. 726 72720130129: 728 A BSD-licensed patch(1) variant has been added and is installed 729 as bsdpatch, being the GNU version the default patch. 730 To inverse the logic and use the BSD-licensed one as default, 731 while having the GNU version installed as gnupatch, rebuild 732 and install world with the WITH_BSD_PATCH knob set. 733 73420130121: 735 Due to the use of the new -l option to install(1) during build 736 and install, you must take care not to directly set the INSTALL 737 make variable in your /etc/make.conf, /etc/src.conf, or on the 738 command line. If you wish to use the -C flag for all installs 739 you may be able to add INSTALL+=-C to /etc/make.conf or 740 /etc/src.conf. 741 74220130118: 743 The install(1) option -M has changed meaning and now takes an 744 argument that is a file or path to append logs to. In the 745 unlikely event that -M was the last option on the command line 746 and the command line contained at least two files and a target 747 directory the first file will have logs appended to it. The -M 748 option served little practical purpose in the last decade so its 749 use is expected to be extremely rare. 750 75120121223: 752 After switching to Clang as the default compiler some users of ZFS 753 on i386 systems started to experience stack overflow kernel panics. 754 Please consider using 'options KSTACK_PAGES=4' in such configurations. 755 75620121222: 757 GEOM_LABEL now mangles label names read from file system metadata. 758 Mangling affect labels containing spaces, non-printable characters, 759 '%' or '"'. Device names in /etc/fstab and other places may need to 760 be updated. 761 76220121217: 763 By default, only the 10 most recent kernel dumps will be saved. To 764 restore the previous behaviour (no limit on the number of kernel dumps 765 stored in the dump directory) add the following line to /etc/rc.conf: 766 767 savecore_flags="" 768 76920121201: 770 With the addition of auditdistd(8), a new auditdistd user is now 771 required during installworld. "mergemaster -p" can be used to 772 add the user prior to installworld, as documented in the handbook. 773 77420121117: 775 The sin6_scope_id member variable in struct sockaddr_in6 is now 776 filled by the kernel before passing the structure to the userland via 777 sysctl or routing socket. This means the KAME-specific embedded scope 778 id in sin6_addr.s6_addr[2] is always cleared in userland application. 779 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 780 __FreeBSD_version is bumped to 1000025. 781 78220121105: 783 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 784 This means that the world and kernel will be compiled with clang 785 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 786 and /usr/bin/cpp. To disable this behavior and revert to building 787 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 788 of current may need to bootstrap WITHOUT_CLANG first if the clang 789 build fails (its compatibility window doesn't extend to the 9 stable 790 branch point). 791 79220121102: 793 The IPFIREWALL_FORWARD kernel option has been removed. Its 794 functionality now turned on by default. 795 79620121023: 797 The ZERO_COPY_SOCKET kernel option has been removed and 798 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 799 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 800 mechanism which is not safe and may result in kernel crashes. 801 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 802 driver supports disposeable external page sized mbuf storage. 803 Proper replacements for both zero-copy mechanisms are under 804 consideration and will eventually lead to complete removal 805 of the two kernel options. 806 80720121023: 808 The IPv4 network stack has been converted to network byte 809 order. The following modules need to be recompiled together 810 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 811 pf(4), ipfw(4), ng_ipfw(4), stf(4). 812 81320121022: 814 Support for non-MPSAFE filesystems was removed from VFS. The 815 VFS_VERSION was bumped, all filesystem modules shall be 816 recompiled. 817 81820121018: 819 All the non-MPSAFE filesystems have been disconnected from 820 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 821 portalfs, smbfs, xfs. 822 82320121016: 824 The interface cloning API and ABI has changed. The following 825 modules need to be recompiled together with kernel: 826 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 827 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 828 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 829 83020121015: 831 The sdhci driver was split in two parts: sdhci (generic SD Host 832 Controller logic) and sdhci_pci (actual hardware driver). 833 No kernel config modifications are required, but if you 834 load sdhc as a module you must switch to sdhci_pci instead. 835 83620121014: 837 Import the FUSE kernel and userland support into base system. 838 83920121013: 840 The GNU sort(1) program has been removed since the BSD-licensed 841 sort(1) has been the default for quite some time and no serious 842 problems have been reported. The corresponding WITH_GNU_SORT 843 knob has also gone. 844 84520121006: 846 The pfil(9) API/ABI for AF_INET family has been changed. Packet 847 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 848 with new kernel. 849 85020121001: 851 The net80211(4) ABI has been changed to allow for improved driver 852 PS-POLL and power-save support. All wireless drivers need to be 853 recompiled to work with the new kernel. 854 85520120913: 856 The random(4) support for the VIA hardware random number 857 generator (`PADLOCK') is no longer enabled unconditionally. 858 Add the padlock_rng device in the custom kernel config if 859 needed. The GENERIC kernels on i386 and amd64 do include the 860 device, so the change only affects the custom kernel 861 configurations. 862 86320120908: 864 The pf(4) packet filter ABI has been changed. pfctl(8) and 865 snmp_pf module need to be recompiled to work with new kernel. 866 86720120828: 868 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 869 to -HEAD. Pools that have empty_bpobj in active state can not be 870 imported read-write with ZFS implementations that do not support 871 this feature. For more information read the zpool-features(5) 872 manual page. 873 87420120727: 875 The sparc64 ZFS loader has been changed to no longer try to auto- 876 detect ZFS providers based on diskN aliases but now requires these 877 to be explicitly listed in the OFW boot-device environment variable. 878 87920120712: 880 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 881 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 882 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 883 88420120712: 885 The following sysctls and tunables have been renamed for consistency 886 with other variables: 887 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 888 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 889 89020120628: 891 The sort utility has been replaced with BSD sort. For now, GNU sort 892 is also available as "gnusort" or the default can be set back to 893 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 894 installed as "bsdsort". 895 89620120611: 897 A new version of ZFS (pool version 5000) has been merged to -HEAD. 898 Starting with this version the old system of ZFS pool versioning 899 is superseded by "feature flags". This concept enables forward 900 compatibility against certain future changes in functionality of ZFS 901 pools. The first read-only compatible "feature flag" for ZFS pools 902 is named "com.delphix:async_destroy". For more information 903 read the new zpool-features(5) manual page. 904 Please refer to the "ZFS notes" section of this file for information 905 on upgrading boot ZFS pools. 906 90720120417: 908 The malloc(3) implementation embedded in libc now uses sources imported 909 as contrib/jemalloc. The most disruptive API change is to 910 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 911 delete it prior to installworld, and optionally re-create it using the 912 new format after rebooting. See malloc.conf(5) for details 913 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 914 NAMESPACE section). 915 91620120328: 917 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 918 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 919 now spelled mips. This is to aid compatibility with third-party 920 software that expects this naming scheme in uname(3). Little-endian 921 settings are unchanged. If you are updating a big-endian mips64 machine 922 from before this change, you may need to set MACHINE_ARCH=mips64 in 923 your environment before the new build system will recognize your machine. 924 92520120306: 926 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 927 platforms. 928 92920120229: 930 Now unix domain sockets behave "as expected" on nullfs(5). Previously 931 nullfs(5) did not pass through all behaviours to the underlying layer, 932 as a result if we bound to a socket on the lower layer we could connect 933 only to the lower path; if we bound to the upper layer we could connect 934 only to the upper path. The new behavior is one can connect to both the 935 lower and the upper paths regardless what layer path one binds to. 936 93720120211: 938 The getifaddrs upgrade path broken with 20111215 has been restored. 939 If you have upgraded in between 20111215 and 20120209 you need to 940 recompile libc again with your kernel. You still need to recompile 941 world to be able to configure CARP but this restriction already 942 comes from 20111215. 943 94420120114: 945 The set_rcvar() function has been removed from /etc/rc.subr. All 946 base and ports rc.d scripts have been updated, so if you have a 947 port installed with a script in /usr/local/etc/rc.d you can either 948 hand-edit the rcvar= line, or reinstall the port. 949 950 An easy way to handle the mass-update of /etc/rc.d: 951 rm /etc/rc.d/* && mergemaster -i 952 95320120109: 954 panic(9) now stops other CPUs in the SMP systems, disables interrupts 955 on the current CPU and prevents other threads from running. 956 This behavior can be reverted using the kern.stop_scheduler_on_panic 957 tunable/sysctl. 958 The new behavior can be incompatible with kern.sync_on_panic. 959 96020111215: 961 The carp(4) facility has been changed significantly. Configuration 962 of the CARP protocol via ifconfig(8) has changed, as well as format 963 of CARP events submitted to devd(8) has changed. See manual pages 964 for more information. The arpbalance feature of carp(4) is currently 965 not supported anymore. 966 967 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 968 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 969 need to be recompiled. 970 97120111122: 972 The acpi_wmi(4) status device /dev/wmistat has been renamed to 973 /dev/wmistat0. 974 97520111108: 976 The option VFS_ALLOW_NONMPSAFE option has been added in order to 977 explicitely support non-MPSAFE filesystems. 978 It is on by default for all supported platform at this present 979 time. 980 98120111101: 982 The broken amd(4) driver has been replaced with esp(4) in the amd64, 983 i386 and pc98 GENERIC kernel configuration files. 984 98520110930: 986 sysinstall has been removed 987 98820110923: 989 The stable/9 branch created in subversion. This corresponds to the 990 RELENG_9 branch in CVS. 991 992COMMON ITEMS: 993 994 General Notes 995 ------------- 996 Avoid using make -j when upgrading. While generally safe, there are 997 sometimes problems using -j to upgrade. If your upgrade fails with 998 -j, please try again without -j. From time to time in the past there 999 have been problems using -j with buildworld and/or installworld. This 1000 is especially true when upgrading between "distant" versions (eg one 1001 that cross a major release boundary or several minor releases, or when 1002 several months have passed on the -current branch). 1003 1004 Sometimes, obscure build problems are the result of environment 1005 poisoning. This can happen because the make utility reads its 1006 environment when searching for values for global variables. To run 1007 your build attempts in an "environmental clean room", prefix all make 1008 commands with 'env -i '. See the env(1) manual page for more details. 1009 1010 When upgrading from one major version to another it is generally best 1011 to upgrade to the latest code in the currently installed branch first, 1012 then do an upgrade to the new branch. This is the best-tested upgrade 1013 path, and has the highest probability of being successful. Please try 1014 this approach before reporting problems with a major version upgrade. 1015 1016 When upgrading a live system, having a root shell around before 1017 installing anything can help undo problems. Not having a root shell 1018 around can lead to problems if pam has changed too much from your 1019 starting point to allow continued authentication after the upgrade. 1020 1021 ZFS notes 1022 --------- 1023 When upgrading the boot ZFS pool to a new version, always follow 1024 these two steps: 1025 1026 1.) recompile and reinstall the ZFS boot loader and boot block 1027 (this is part of "make buildworld" and "make installworld") 1028 1029 2.) update the ZFS boot block on your boot drive 1030 1031 The following example updates the ZFS boot block on the first 1032 partition (freebsd-boot) of a GPT partitioned drive ada0: 1033 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1034 1035 Non-boot pools do not need these updates. 1036 1037 To build a kernel 1038 ----------------- 1039 If you are updating from a prior version of FreeBSD (even one just 1040 a few days old), you should follow this procedure. It is the most 1041 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1042 1043 make kernel-toolchain 1044 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1045 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1046 1047 To test a kernel once 1048 --------------------- 1049 If you just want to boot a kernel once (because you are not sure 1050 if it works, or if you want to boot a known bad kernel to provide 1051 debugging information) run 1052 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1053 nextboot -k testkernel 1054 1055 To just build a kernel when you know that it won't mess you up 1056 -------------------------------------------------------------- 1057 This assumes you are already running a CURRENT system. Replace 1058 ${arch} with the architecture of your machine (e.g. "i386", 1059 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1060 1061 cd src/sys/${arch}/conf 1062 config KERNEL_NAME_HERE 1063 cd ../compile/KERNEL_NAME_HERE 1064 make depend 1065 make 1066 make install 1067 1068 If this fails, go to the "To build a kernel" section. 1069 1070 To rebuild everything and install it on the current system. 1071 ----------------------------------------------------------- 1072 # Note: sometimes if you are running current you gotta do more than 1073 # is listed here if you are upgrading from a really old current. 1074 1075 <make sure you have good level 0 dumps> 1076 make buildworld 1077 make kernel KERNCONF=YOUR_KERNEL_HERE 1078 [1] 1079 <reboot in single user> [3] 1080 mergemaster -Fp [5] 1081 make installworld 1082 mergemaster -Fi [4] 1083 make delete-old [6] 1084 <reboot> 1085 1086 To cross-install current onto a separate partition 1087 -------------------------------------------------- 1088 # In this approach we use a separate partition to hold 1089 # current's root, 'usr', and 'var' directories. A partition 1090 # holding "/", "/usr" and "/var" should be about 2GB in 1091 # size. 1092 1093 <make sure you have good level 0 dumps> 1094 <boot into -stable> 1095 make buildworld 1096 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1097 <maybe newfs current's root partition> 1098 <mount current's root partition on directory ${CURRENT_ROOT}> 1099 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1100 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1101 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1102 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1103 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1104 <reboot into current> 1105 <do a "native" rebuild/install as described in the previous section> 1106 <maybe install compatibility libraries from ports/misc/compat*> 1107 <reboot> 1108 1109 1110 To upgrade in-place from stable to current 1111 ---------------------------------------------- 1112 <make sure you have good level 0 dumps> 1113 make buildworld [9] 1114 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1115 [1] 1116 <reboot in single user> [3] 1117 mergemaster -Fp [5] 1118 make installworld 1119 mergemaster -Fi [4] 1120 make delete-old [6] 1121 <reboot> 1122 1123 Make sure that you've read the UPDATING file to understand the 1124 tweaks to various things you need. At this point in the life 1125 cycle of current, things change often and you are on your own 1126 to cope. The defaults can also change, so please read ALL of 1127 the UPDATING entries. 1128 1129 Also, if you are tracking -current, you must be subscribed to 1130 freebsd-current@freebsd.org. Make sure that before you update 1131 your sources that you have read and understood all the recent 1132 messages there. If in doubt, please track -stable which has 1133 much fewer pitfalls. 1134 1135 [1] If you have third party modules, such as vmware, you 1136 should disable them at this point so they don't crash your 1137 system on reboot. 1138 1139 [3] From the bootblocks, boot -s, and then do 1140 fsck -p 1141 mount -u / 1142 mount -a 1143 cd src 1144 adjkerntz -i # if CMOS is wall time 1145 Also, when doing a major release upgrade, it is required that 1146 you boot into single user mode to do the installworld. 1147 1148 [4] Note: This step is non-optional. Failure to do this step 1149 can result in a significant reduction in the functionality of the 1150 system. Attempting to do it by hand is not recommended and those 1151 that pursue this avenue should read this file carefully, as well 1152 as the archives of freebsd-current and freebsd-hackers mailing lists 1153 for potential gotchas. The -U option is also useful to consider. 1154 See mergemaster(8) for more information. 1155 1156 [5] Usually this step is a noop. However, from time to time 1157 you may need to do this if you get unknown user in the following 1158 step. It never hurts to do it all the time. You may need to 1159 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1160 install) after the buildworld before this step if you last updated 1161 from current before 20130425 or from -stable before 20130430. 1162 1163 [6] This only deletes old files and directories. Old libraries 1164 can be deleted by "make delete-old-libs", but you have to make 1165 sure that no program is using those libraries anymore. 1166 1167 [8] In order to have a kernel that can run the 4.x binaries needed to 1168 do an installworld, you must include the COMPAT_FREEBSD4 option in 1169 your kernel. Failure to do so may leave you with a system that is 1170 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1171 required to run the 5.x binaries on more recent kernels. And so on 1172 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1173 1174 Make sure that you merge any new devices from GENERIC since the 1175 last time you updated your kernel config file. 1176 1177 [9] When checking out sources, you must include the -P flag to have 1178 cvs prune empty directories. 1179 1180 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1181 "?=" instead of the "=" assignment operator, so that buildworld can 1182 override the CPUTYPE if it needs to. 1183 1184 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1185 not on the command line, or in /etc/make.conf. buildworld will 1186 warn if it is improperly defined. 1187FORMAT: 1188 1189This file contains a list, in reverse chronological order, of major 1190breakages in tracking -current. It is not guaranteed to be a complete 1191list of such breakages, and only contains entries since October 10, 2007. 1192If you need to see UPDATING entries from before that date, you will need 1193to fetch an UPDATING file from an older FreeBSD release. 1194 1195Copyright information: 1196 1197Copyright 1998-2009 M.
