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 342015mmdd: 35 Clang and llvm have been upgraded to 3.7.0. Please see the 36 20141231 entry below for information about prerequisites and upgrading, 37 if you are not already using 3.5.0 or higher. 38 3920150525: 40 Clang and llvm have been upgraded to 3.6.1 release. Please see the 41 20141231 entry below for information about prerequisites and upgrading, 42 if you are not already using 3.5.0 or higher. 43 4420150521: 45 TI platform code switched to using vendor DTS files and this update 46 may break existing systems running on Beaglebone, Beaglebone Black, 47 and Pandaboard: 48 49 - dtb files should be regenerated/reinstalled. Filenames are the 50 same but content is different now 51 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 52 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 53 addressing scheme is now pin 25 on /dev/gpioc3. 54 - Pandaboard: /etc/ttys should be updated, serial console device is 55 now /dev/ttyu2, not /dev/ttyu0 56 5720150501: 58 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 59 If you need the GNU extension from groff soelim(1), install groff 60 from package: pkg install groff, or via ports: textproc/groff. 61 6220150423: 63 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 64 defined in symlink(7); previously symlinks were silently ignored. 65 6620150415: 67 The const qualifier has been removed from iconv(3) to comply with 68 POSIX. The ports tree is aware of this from r384038 onwards. 69 7020150416: 71 Libraries specified by LIBADD in Makefiles must have a corresponding 72 DPADD_<lib> variable to ensure correct dependencies. This is now 73 enforced in src.libnames.mk. 74 7520150324: 76 From legacy ata(4) driver was removed support for SATA controllers 77 supported by more functional drivers ahci(4), siis(4) and mvs(4). 78 Kernel modules ataahci and ataadaptec were removed completely, 79 replaced by ahci and mvs modules respectively. 80 8120150315: 82 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 83 the 20141231 entry below for information about prerequisites and 84 upgrading, if you are not already using 3.5.0 or higher. 85 8620150307: 87 The 32-bit PowerPC kernel has been changed to a position-independent 88 executable. This can only be booted with a version of loader(8) 89 newer than January 31, 2015, so make sure to update both world and 90 kernel before rebooting. 91 9220150217: 93 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 94 but before r278950, the RNG was not seeded properly. Immediately 95 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 96 ssh keys or openssl keys) that were generated w/ a kernel from that 97 range. This does not affect programs that directly used /dev/random 98 or /dev/urandom. All userland uses of arc4random(3) are affected. 99 10020150210: 101 The autofs(4) ABI was changed in order to restore binary compatibility 102 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 103 with the new kernel. 104 10520150131: 106 The powerpc64 kernel has been changed to a position-independent 107 executable. This can only be booted with a new version of loader(8), 108 so make sure to update both world and kernel before rebooting. 109 11020150118: 111 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 112 only release, no new features have been added. Please see the 20141231 113 entry below for information about prerequisites and upgrading, if you 114 are not already using 3.5.0. 115 11620150107: 117 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 118 taken from the ELF Tool Chain project rather than GNU binutils. They 119 should be drop-in replacements, with the addition of arm64 support. 120 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 121 binutils tools, if necessary. 122 12320150105: 124 The default Unbound configuration now enables remote control 125 using a local socket. Users who have already enabled the 126 local_unbound service should regenerate their configuration 127 by running "service local_unbound setup" as root. 128 12920150102: 130 The GNU texinfo and GNU info pages have been removed. 131 To be able to view GNU info pages please install texinfo from ports. 132 13320141231: 134 Clang, llvm and lldb have been upgraded to 3.5.0 release. 135 136 As of this release, a prerequisite for building clang, llvm and lldb is 137 a C++11 capable compiler and C++11 standard library. This means that to 138 be able to successfully build the cross-tools stage of buildworld, with 139 clang as the bootstrap compiler, your system compiler or cross compiler 140 should either be clang 3.3 or later, or gcc 4.8 or later, and your 141 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 142 later. 143 144 On any standard FreeBSD 10.x or 11.x installation, where clang and 145 libc++ are on by default (that is, on x86 or arm), this should work out 146 of the box. 147 148 On 9.x installations where clang is enabled by default, e.g. on x86 and 149 powerpc, libc++ will not be enabled by default, so libc++ should be 150 built (with clang) and installed first. If both clang and libc++ are 151 missing, build clang first, then use it to build libc++. 152 153 On 8.x and earlier installations, upgrade to 9.x first, and then follow 154 the instructions for 9.x above. 155 156 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 157 default, and do not build clang. 158 159 Many embedded systems are resource constrained, and will not be able to 160 build clang in a reasonable time, or in some cases at all. In those 161 cases, cross building bootable systems on amd64 is a workaround. 162 163 This new version of clang introduces a number of new warnings, of which 164 the following are most likely to appear: 165 166 -Wabsolute-value 167 168 This warns in two cases, for both C and C++: 169 * When the code is trying to take the absolute value of an unsigned 170 quantity, which is effectively a no-op, and almost never what was 171 intended. The code should be fixed, if at all possible. If you are 172 sure that the unsigned quantity can be safely cast to signed, without 173 loss of information or undefined behavior, you can add an explicit 174 cast, or disable the warning. 175 176 * When the code is trying to take an absolute value, but the called 177 abs() variant is for the wrong type, which can lead to truncation. 178 If you want to disable the warning instead of fixing the code, please 179 make sure that truncation will not occur, or it might lead to unwanted 180 side-effects. 181 182 -Wtautological-undefined-compare and 183 -Wundefined-bool-conversion 184 185 These warn when C++ code is trying to compare 'this' against NULL, while 186 'this' should never be NULL in well-defined C++ code. However, there is 187 some legacy (pre C++11) code out there, which actively abuses this 188 feature, which was less strictly defined in previous C++ versions. 189 190 Squid and openjdk do this, for example. The warning can be turned off 191 for C++98 and earlier, but compiling the code in C++11 mode might result 192 in unexpected behavior; for example, the parts of the program that are 193 unreachable could be optimized away. 194 19520141222: 196 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 197 kernel sources have been removed. The .h files remain, since some 198 utilities include them. This will need to be fixed later. 199 If "mount -t oldnfs ..." is attempted, it will fail. 200 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 201 the utilities will report errors. 202 20320141121: 204 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 205 directories to top level SUBDIR variable when their parent 206 directory is included in LOCAL_DIRS. Users with build systems with 207 such hierarchies and without SUBDIR entries in the parent 208 directory Makefiles should add them or add the directories to 209 LOCAL_DIRS. 210 21120141109: 212 faith(4) and faithd(8) have been removed from the base system. Faith 213 has been obsolete for a very long time. 214 21520141104: 216 vt(4), the new console driver, is enabled by default. It brings 217 support for Unicode and double-width characters, as well as 218 support for UEFI and integration with the KMS kernel video 219 drivers. 220 221 You may need to update your console settings in /etc/rc.conf, 222 most probably the keymap. During boot, /etc/rc.d/syscons will 223 indicate what you need to do. 224 225 vt(4) still has issues and lacks some features compared to 226 syscons(4). See the wiki for up-to-date information: 227 https://wiki.freebsd.org/Newcons 228 229 If you want to keep using syscons(4), you can do so by adding 230 the following line to /boot/loader.conf: 231 kern.vty=sc 232 23320141102: 234 pjdfstest has been integrated into kyua as an opt-in test suite. 235 Please see share/doc/pjdfstest/README for more details on how to 236 execute it. 237 23820141009: 239 gperf has been removed from the base system for architectures 240 that use clang. Ports that require gperf will obtain it from the 241 devel/gperf port. 242 24320140923: 244 pjdfstest has been moved from tools/regression/pjdfstest to 245 contrib/pjdfstest . 246 24720140922: 248 At svn r271982, The default linux compat kernel ABI has been adjusted 249 to 2.6.18 in support of the linux-c6 compat ports infrastructure 250 update. If you wish to continue using the linux-f10 compat ports, 251 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 252 encouraged to update their linux-compat packages to linux-c6 during 253 their next update cycle. 254 25520140729: 256 The ofwfb driver, used to provide a graphics console on PowerPC when 257 using vt(4), no longer allows mmap() of all physical memory. This 258 will prevent Xorg on PowerPC with some ATI graphics cards from 259 initializing properly unless x11-servers/xorg-server is updated to 260 1.12.4_8 or newer. 261 26220140723: 263 The xdev targets have been converted to using TARGET and 264 TARGET_ARCH instead of XDEV and XDEV_ARCH. 265 26620140719: 267 The default unbound configuration has been modified to address 268 issues with reverse lookups on networks that use private 269 address ranges. If you use the local_unbound service, run 270 "service local_unbound setup" as root to regenerate your 271 configuration, then "service local_unbound reload" to load the 272 new configuration. 273 27420140709: 275 The GNU texinfo and GNU info pages are not built and installed 276 anymore, WITH_INFO knob has been added to allow to built and install 277 them again. 278 UPDATE: see 20150102 entry on texinfo's removal 279 28020140708: 281 The GNU readline library is now an INTERNALLIB - that is, it is 282 statically linked into consumers (GDB and variants) in the base 283 system, and the shared library is no longer installed. The 284 devel/readline port is available for third party software that 285 requires readline. 286 28720140702: 288 The Itanium architecture (ia64) has been removed from the list of 289 known architectures. This is the first step in the removal of the 290 architecture. 291 29220140701: 293 Commit r268115 has added NFSv4.1 server support, merged from 294 projects/nfsv4.1-server. Since this includes changes to the 295 internal interfaces between the NFS related modules, a full 296 build of the kernel and modules will be necessary. 297 __FreeBSD_version has been bumped. 298 29920140629: 300 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 301 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 302 which differs from the behaviour controlled by this knob.) 303 30420140619: 305 Maximal length of the serial number in CTL was increased from 16 to 306 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 307 and ctld, need to be rebuilt to work with a new kernel. 308 30920140606: 310 The libatf-c and libatf-c++ major versions were downgraded to 0 and 311 1 respectively to match the upstream numbers. They were out of 312 sync because, when they were originally added to FreeBSD, the 313 upstream versions were not respected. These libraries are private 314 and not yet built by default, so renumbering them should be a 315 non-issue. However, unclean source trees will yield broken test 316 programs once the operator executes "make delete-old-libs" after a 317 "make installworld". 318 319 Additionally, the atf-sh binary was made private by moving it into 320 /usr/libexec/. Already-built shell test programs will keep the 321 path to the old binary so they will break after "make delete-old" 322 is run. 323 324 If you are using WITH_TESTS=yes (not the default), wipe the object 325 tree and rebuild from scratch to prevent spurious test failures. 326 This is only needed once: the misnumbered libraries and misplaced 327 binaries have been added to OptionalObsoleteFiles.inc so they will 328 be removed during a clean upgrade. 329 33020140512: 331 Clang and llvm have been upgraded to 3.4.1 release. 332 33320140508: 334 We bogusly installed src.opts.mk in /usr/share/mk. This file should 335 be removed to avoid issues in the future (and has been added to 336 ObsoleteFiles.inc). 337 33820140505: 339 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 340 past, it affected all builds that used the bsd.*.mk files. The old 341 behavior was a bug, but people may have relied upon it. To get this 342 behavior back, you can .include /etc/src.conf from /etc/make.conf 343 (which is still global and isn't changed). This also changes the 344 behavior of incremental builds inside the tree of individual 345 directories. Set MAKESYSPATH to ".../share/mk" to do that. 346 Although this has survived make universe and some upgrade scenarios, 347 other upgrade scenarios may have broken. At least one form of 348 temporary breakage was fixed with MAKESYSPATH settings for buildworld 349 as well... In cases where MAKESYSPATH isn't working with this 350 setting, you'll need to set it to the full path to your tree. 351 352 One side effect of all this cleaning up is that bsd.compiler.mk 353 is no longer implicitly included by bsd.own.mk. If you wish to 354 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 355 as well. 356 35720140430: 358 The lindev device has been removed since /dev/full has been made a 359 standard device. __FreeBSD_version has been bumped. 360 36120140424: 362 The knob WITHOUT_VI was added to the base system, which controls 363 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 364 in order to reorder files share/termcap and didn't build ex(1) as a 365 build tool, so building/installing with WITH_VI is highly advised for 366 build hosts for older releases. 367 368 This issue has been fixed in stable/9 and stable/10 in r277022 and 369 r276991, respectively. 370 37120140418: 372 The YES_HESIOD knob has been removed. It has been obsolete for 373 a decade. Please move to using WITH_HESIOD instead or your builds 374 will silently lack HESIOD. 375 37620140405: 377 The uart(4) driver has been changed with respect to its handling 378 of the low-level console. Previously the uart(4) driver prevented 379 any process from changing the baudrate or the CLOCAL and HUPCL 380 control flags. By removing the restrictions, operators can make 381 changes to the serial console port without having to reboot. 382 However, when getty(8) is started on the serial device that is 383 associated with the low-level console, a misconfigured terminal 384 line in /etc/ttys will now have a real impact. 385 Before upgrading the kernel, make sure that /etc/ttys has the 386 serial console device configured as 3wire without baudrate to 387 preserve the previous behaviour. E.g: 388 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 389 39020140306: 391 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 392 to improve performance. To re-enable it, if needed, run rpcbind 393 with command line option -W. 394 39520140226: 396 Switched back to the GPL dtc compiler due to updates in the upstream 397 dts files not being supported by the BSDL dtc compiler. You will need 398 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 399 may result while building dtb files during a kernel build if you fail 400 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 401 40220140216: 403 Clang and llvm have been upgraded to 3.4 release. 404 40520140216: 406 The nve(4) driver has been removed. Please use the nfe(4) driver 407 for NVIDIA nForce MCP Ethernet adapters instead. 408 40920140212: 410 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 411 This could cause certain C++ applications using shared libraries built 412 against the previous version of libc++ to crash. The incompatibility 413 has now been fixed, but any C++ applications or shared libraries built 414 between r261283 and r261801 should be recompiled. 415 41620140204: 417 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 418 capability mode support. Please note that enabling the feature in 419 kernel is still highly recommended. 420 42120140131: 422 OpenSSH is now built with sandbox support, and will use sandbox as 423 the default privilege separation method. This requires Capsicum 424 capability mode support in kernel. 425 42620140128: 427 The libelf and libdwarf libraries have been updated to newer 428 versions from upstream. Shared library version numbers for 429 these two libraries were bumped. Any ports or binaries 430 requiring these two libraries should be recompiled. 431 __FreeBSD_version is bumped to 1100006. 432 43320140110: 434 If a Makefile in a tests/ directory was auto-generating a Kyuafile 435 instead of providing an explicit one, this would prevent such 436 Makefile from providing its own Kyuafile in the future during 437 NO_CLEAN builds. This has been fixed in the Makefiles but manual 438 intervention is needed to clean an objdir if you use NO_CLEAN: 439 # find /usr/obj -name Kyuafile | xargs rm -f 440 44120131213: 442 The behavior of gss_pseudo_random() for the krb5 mechanism 443 has changed, for applications requesting a longer random string 444 than produced by the underlying enctype's pseudo-random() function. 445 In particular, the random string produced from a session key of 446 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 447 be different at the 17th octet and later, after this change. 448 The counter used in the PRF+ construction is now encoded as a 449 big-endian integer in accordance with RFC 4402. 450 __FreeBSD_version is bumped to 1100004. 451 45220131108: 453 The WITHOUT_ATF build knob has been removed and its functionality 454 has been subsumed into the more generic WITHOUT_TESTS. If you were 455 using the former to disable the build of the ATF libraries, you 456 should change your settings to use the latter. 457 45820131025: 459 The default version of mtree is nmtree which is obtained from 460 NetBSD. The output is generally the same, but may vary 461 slightly. If you found you need identical output adding 462 "-F freebsd9" to the command line should do the trick. For the 463 time being, the old mtree is available as fmtree. 464 46520131014: 466 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 467 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 468 1.1.4_8 and verify bsdyml not linked in, before running "make 469 delete-old-libs": 470 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 471 or 472 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 473 47420131010: 475 The rc.d/jail script has been updated to support jail(8) 476 configuration file. The "jail_<jname>_*" rc.conf(5) variables 477 for per-jail configuration are automatically converted to 478 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 479 This is transparently backward compatible. See below about some 480 incompatibilities and rc.conf(5) manual page for more details. 481 482 These variables are now deprecated in favor of jail(8) configuration 483 file. One can use "rc.d/jail config <jname>" command to generate 484 a jail(8) configuration file in /var/run/jail.<jname>.conf without 485 running the jail(8) utility. The default pathname of the 486 configuration file is /etc/jail.conf and can be specified by 487 using $jail_conf or $jail_<jname>_conf variables. 488 489 Please note that jail_devfs_ruleset accepts an integer at 490 this moment. Please consider to rewrite the ruleset name 491 with an integer. 492 49320130930: 494 BIND has been removed from the base system. If all you need 495 is a local resolver, simply enable and start the local_unbound 496 service instead. Otherwise, several versions of BIND are 497 available in the ports tree. The dns/bind99 port is one example. 498 499 With this change, nslookup(1) and dig(1) are no longer in the base 500 system. Users should instead use host(1) and drill(1) which are 501 in the base system. Alternatively, nslookup and dig can 502 be obtained by installing the dns/bind-tools port. 503 50420130916: 505 With the addition of unbound(8), a new unbound user is now 506 required during installworld. "mergemaster -p" can be used to 507 add the user prior to installworld, as documented in the handbook. 508 50920130911: 510 OpenSSH is now built with DNSSEC support, and will by default 511 silently trust signed SSHFP records. This can be controlled with 512 the VerifyHostKeyDNS client configuration setting. DNSSEC support 513 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 514 51520130906: 516 The GNU Compiler Collection and C++ standard library (libstdc++) 517 are no longer built by default on platforms where clang is the system 518 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 519 options in src.conf. 520 52120130905: 522 The PROCDESC kernel option is now part of the GENERIC kernel 523 configuration and is required for the rwhod(8) to work. 524 If you are using custom kernel configuration, you should include 525 'options PROCDESC'. 526 52720130905: 528 The API and ABI related to the Capsicum framework was modified 529 in backward incompatible way. The userland libraries and programs 530 have to be recompiled to work with the new kernel. This includes the 531 following libraries and programs, but the whole buildworld is 532 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 533 kdump, procstat, rwho, rwhod, uniq. 534 53520130903: 536 AES-NI intrinsic support has been added to gcc. The AES-NI module 537 has been updated to use this support. A new gcc is required to build 538 the aesni module on both i386 and amd64. 539 54020130821: 541 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 542 Thus "device padlock_rng" and "device rdrand_rng" should be 543 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 544 54520130813: 546 WITH_ICONV has been split into two feature sets. WITH_ICONV now 547 enables just the iconv* functionality and is now on by default. 548 WITH_LIBICONV_COMPAT enables the libiconv api and link time 549 compatability. Set WITHOUT_ICONV to build the old way. 550 If you have been using WITH_ICONV before, you will very likely 551 need to turn on WITH_LIBICONV_COMPAT. 552 55320130806: 554 INVARIANTS option now enables DEBUG for code with OpenSolaris and 555 Illumos origin, including ZFS. If you have INVARIANTS in your 556 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 557 explicitly. 558 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 559 locks if WITNESS option was set. Because that generated a lot of 560 witness(9) reports and all of them were believed to be false 561 positives, this is no longer done. New option OPENSOLARIS_WITNESS 562 can be used to achieve the previous behavior. 563 56420130806: 565 Timer values in IPv6 data structures now use time_uptime instead 566 of time_second. Although this is not a user-visible functional 567 change, userland utilities which directly use them---ndp(8), 568 rtadvd(8), and rtsold(8) in the base system---need to be updated 569 to r253970 or later. 570 57120130802: 572 find -delete can now delete the pathnames given as arguments, 573 instead of only files found below them or if the pathname did 574 not contain any slashes. Formerly, the following error message 575 would result: 576 577 find: -delete: <path>: relative path potentially not safe 578 579 Deleting the pathnames given as arguments can be prevented 580 without error messages using -mindepth 1 or by changing 581 directory and passing "." as argument to find. This works in the 582 old as well as the new version of find. 583 58420130726: 585 Behavior of devfs rules path matching has been changed. 586 Pattern is now always matched against fully qualified devfs 587 path and slash characters must be explicitly matched by 588 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 589 subdirectories must be reviewed. 590 59120130716: 592 The default ARM ABI has changed to the ARM EABI. The old ABI is 593 incompatible with the ARM EABI and all programs and modules will 594 need to be rebuilt to work with a new kernel. 595 596 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 597 598 NOTE: Support for the old ABI will be removed in the future and 599 users are advised to upgrade. 600 60120130709: 602 pkg_install has been disconnected from the build if you really need it 603 you should add WITH_PKGTOOLS in your src.conf(5). 604 60520130709: 606 Most of network statistics structures were changed to be able 607 keep 64-bits counters. Thus all tools, that work with networking 608 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 609 61020130629: 611 Fix targets that run multiple make's to use && rather than ; 612 so that subsequent steps depend on success of previous. 613 614 NOTE: if building 'universe' with -j* on stable/8 or stable/9 615 it would be better to start the build using bmake, to avoid 616 overloading the machine. 617 61820130618: 619 Fix a bug that allowed a tracing process (e.g. gdb) to write 620 to a memory-mapped file in the traced process's address space 621 even if neither the traced process nor the tracing process had 622 write access to that file. 623 62420130615: 625 CVS has been removed from the base system. An exact copy 626 of the code is available from the devel/cvs port. 627 62820130613: 629 Some people report the following error after the switch to bmake: 630 631 make: illegal option -- J 632 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 633 ... 634 *** [buildworld] Error code 2 635 636 this likely due to an old instance of make in 637 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 638 which src/Makefile will use that blindly, if it exists, so if 639 you see the above error: 640 641 rm -rf `make -V MAKEPATH` 642 643 should resolve it. 644 64520130516: 646 Use bmake by default. 647 Whereas before one could choose to build with bmake via 648 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 649 make. The goal is to remove these knobs for 10-RELEASE. 650 651 It is worth noting that bmake (like gmake) treats the command 652 line as the unit of failure, rather than statements within the 653 command line. Thus '(cd some/where && dosomething)' is safer 654 than 'cd some/where; dosomething'. The '()' allows consistent 655 behavior in parallel build. 656 65720130429: 658 Fix a bug that allows NFS clients to issue READDIR on files. 659 66020130426: 661 The WITHOUT_IDEA option has been removed because 662 the IDEA patent expired. 663 66420130426: 665 The sysctl which controls TRIM support under ZFS has been renamed 666 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 667 enabled by default. 668 66920130425: 670 The mergemaster command now uses the default MAKEOBJDIRPREFIX 671 rather than creating it's own in the temporary directory in 672 order allow access to bootstrapped versions of tools such as 673 install and mtree. When upgrading from version of FreeBSD where 674 the install command does not support -l, you will need to 675 install a new mergemaster command if mergemaster -p is required. 676 This can be accomplished with the command (cd src/usr.sbin/mergemaster 677 && make install). 678 67920130404: 680 Legacy ATA stack, disabled and replaced by new CAM-based one since 681 FreeBSD 9.0, completely removed from the sources. Kernel modules 682 atadisk and atapi*, user-level tools atacontrol and burncd are 683 removed. Kernel option `options ATA_CAM` is now permanently enabled 684 and removed. 685 68620130319: 687 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 688 and socketpair(2). Software, in particular Kerberos, may 689 automatically detect and use these during building. The resulting 690 binaries will not work on older kernels. 691 69220130308: 693 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 694 information, see the respective 20130304 entry). 695 69620130304: 697 Recent commits to callout(9) changed the size of struct callout, 698 so the KBI is probably heavily disturbed. Also, some functions 699 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 700 by macros. Every kernel module using it won't load, so rebuild 701 is requested. 702 703 The ctl device has been re-enabled in GENERIC for i386 and amd64, 704 but does not initialize by default (because of the new CTL_DISABLE 705 option) to save memory. To re-enable it, remove the CTL_DISABLE 706 option from the kernel config file or set kern.cam.ctl.disable=0 707 in /boot/loader.conf. 708 70920130301: 710 The ctl device has been disabled in GENERIC for i386 and amd64. 711 This was done due to the extra memory being allocated at system 712 initialisation time by the ctl driver which was only used if 713 a CAM target device was created. This makes a FreeBSD system 714 unusable on 128MB or less of RAM. 715 71620130208: 717 A new compression method (lz4) has been merged to -HEAD. Please 718 refer to zpool-features(7) for more information. 719 720 Please refer to the "ZFS notes" section of this file for information 721 on upgrading boot ZFS pools. 722 72320130129: 724 A BSD-licensed patch(1) variant has been added and is installed 725 as bsdpatch, being the GNU version the default patch. 726 To inverse the logic and use the BSD-licensed one as default, 727 while having the GNU version installed as gnupatch, rebuild 728 and install world with the WITH_BSD_PATCH knob set. 729 73020130121: 731 Due to the use of the new -l option to install(1) during build 732 and install, you must take care not to directly set the INSTALL 733 make variable in your /etc/make.conf, /etc/src.conf, or on the 734 command line. If you wish to use the -C flag for all installs 735 you may be able to add INSTALL+=-C to /etc/make.conf or 736 /etc/src.conf. 737 73820130118: 739 The install(1) option -M has changed meaning and now takes an 740 argument that is a file or path to append logs to. In the 741 unlikely event that -M was the last option on the command line 742 and the command line contained at least two files and a target 743 directory the first file will have logs appended to it. The -M 744 option served little practical purpose in the last decade so its 745 use is expected to be extremely rare. 746 74720121223: 748 After switching to Clang as the default compiler some users of ZFS 749 on i386 systems started to experience stack overflow kernel panics. 750 Please consider using 'options KSTACK_PAGES=4' in such configurations. 751 75220121222: 753 GEOM_LABEL now mangles label names read from file system metadata. 754 Mangling affect labels containing spaces, non-printable characters, 755 '%' or '"'. Device names in /etc/fstab and other places may need to 756 be updated. 757 75820121217: 759 By default, only the 10 most recent kernel dumps will be saved. To 760 restore the previous behaviour (no limit on the number of kernel dumps 761 stored in the dump directory) add the following line to /etc/rc.conf: 762 763 savecore_flags="" 764 76520121201: 766 With the addition of auditdistd(8), a new auditdistd user is now 767 required during installworld. "mergemaster -p" can be used to 768 add the user prior to installworld, as documented in the handbook. 769 77020121117: 771 The sin6_scope_id member variable in struct sockaddr_in6 is now 772 filled by the kernel before passing the structure to the userland via 773 sysctl or routing socket. This means the KAME-specific embedded scope 774 id in sin6_addr.s6_addr[2] is always cleared in userland application. 775 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 776 __FreeBSD_version is bumped to 1000025. 777 77820121105: 779 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 780 This means that the world and kernel will be compiled with clang 781 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 782 and /usr/bin/cpp. To disable this behavior and revert to building 783 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 784 of current may need to bootstrap WITHOUT_CLANG first if the clang 785 build fails (its compatibility window doesn't extend to the 9 stable 786 branch point). 787 78820121102: 789 The IPFIREWALL_FORWARD kernel option has been removed. Its 790 functionality now turned on by default. 791 79220121023: 793 The ZERO_COPY_SOCKET kernel option has been removed and 794 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 795 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 796 mechanism which is not safe and may result in kernel crashes. 797 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 798 driver supports disposeable external page sized mbuf storage. 799 Proper replacements for both zero-copy mechanisms are under 800 consideration and will eventually lead to complete removal 801 of the two kernel options. 802 80320121023: 804 The IPv4 network stack has been converted to network byte 805 order. The following modules need to be recompiled together 806 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 807 pf(4), ipfw(4), ng_ipfw(4), stf(4). 808 80920121022: 810 Support for non-MPSAFE filesystems was removed from VFS. The 811 VFS_VERSION was bumped, all filesystem modules shall be 812 recompiled. 813 81420121018: 815 All the non-MPSAFE filesystems have been disconnected from 816 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 817 portalfs, smbfs, xfs. 818 81920121016: 820 The interface cloning API and ABI has changed. The following 821 modules need to be recompiled together with kernel: 822 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 823 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 824 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 825 82620121015: 827 The sdhci driver was split in two parts: sdhci (generic SD Host 828 Controller logic) and sdhci_pci (actual hardware driver). 829 No kernel config modifications are required, but if you 830 load sdhc as a module you must switch to sdhci_pci instead. 831 83220121014: 833 Import the FUSE kernel and userland support into base system. 834 83520121013: 836 The GNU sort(1) program has been removed since the BSD-licensed 837 sort(1) has been the default for quite some time and no serious 838 problems have been reported. The corresponding WITH_GNU_SORT 839 knob has also gone. 840 84120121006: 842 The pfil(9) API/ABI for AF_INET family has been changed. Packet 843 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 844 with new kernel. 845 84620121001: 847 The net80211(4) ABI has been changed to allow for improved driver 848 PS-POLL and power-save support. All wireless drivers need to be 849 recompiled to work with the new kernel. 850 85120120913: 852 The random(4) support for the VIA hardware random number 853 generator (`PADLOCK') is no longer enabled unconditionally. 854 Add the padlock_rng device in the custom kernel config if 855 needed. The GENERIC kernels on i386 and amd64 do include the 856 device, so the change only affects the custom kernel 857 configurations. 858 85920120908: 860 The pf(4) packet filter ABI has been changed. pfctl(8) and 861 snmp_pf module need to be recompiled to work with new kernel. 862 86320120828: 864 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 865 to -HEAD. Pools that have empty_bpobj in active state can not be 866 imported read-write with ZFS implementations that do not support 867 this feature. For more information read the zpool-features(5) 868 manual page. 869 87020120727: 871 The sparc64 ZFS loader has been changed to no longer try to auto- 872 detect ZFS providers based on diskN aliases but now requires these 873 to be explicitly listed in the OFW boot-device environment variable. 874 87520120712: 876 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 877 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 878 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 879 88020120712: 881 The following sysctls and tunables have been renamed for consistency 882 with other variables: 883 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 884 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 885 88620120628: 887 The sort utility has been replaced with BSD sort. For now, GNU sort 888 is also available as "gnusort" or the default can be set back to 889 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 890 installed as "bsdsort". 891 89220120611: 893 A new version of ZFS (pool version 5000) has been merged to -HEAD. 894 Starting with this version the old system of ZFS pool versioning 895 is superseded by "feature flags". This concept enables forward 896 compatibility against certain future changes in functionality of ZFS 897 pools. The first read-only compatible "feature flag" for ZFS pools 898 is named "com.delphix:async_destroy". For more information 899 read the new zpool-features(5) manual page. 900 Please refer to the "ZFS notes" section of this file for information 901 on upgrading boot ZFS pools. 902 90320120417: 904 The malloc(3) implementation embedded in libc now uses sources imported 905 as contrib/jemalloc. The most disruptive API change is to 906 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 907 delete it prior to installworld, and optionally re-create it using the 908 new format after rebooting. See malloc.conf(5) for details 909 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 910 NAMESPACE section). 911 91220120328: 913 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 914 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 915 now spelled mips. This is to aid compatibility with third-party 916 software that expects this naming scheme in uname(3). Little-endian 917 settings are unchanged. If you are updating a big-endian mips64 machine 918 from before this change, you may need to set MACHINE_ARCH=mips64 in 919 your environment before the new build system will recognize your machine. 920 92120120306: 922 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 923 platforms. 924 92520120229: 926 Now unix domain sockets behave "as expected" on nullfs(5). Previously 927 nullfs(5) did not pass through all behaviours to the underlying layer, 928 as a result if we bound to a socket on the lower layer we could connect 929 only to the lower path; if we bound to the upper layer we could connect 930 only to the upper path. The new behavior is one can connect to both the 931 lower and the upper paths regardless what layer path one binds to. 932 93320120211: 934 The getifaddrs upgrade path broken with 20111215 has been restored. 935 If you have upgraded in between 20111215 and 20120209 you need to 936 recompile libc again with your kernel. You still need to recompile 937 world to be able to configure CARP but this restriction already 938 comes from 20111215. 939 94020120114: 941 The set_rcvar() function has been removed from /etc/rc.subr. All 942 base and ports rc.d scripts have been updated, so if you have a 943 port installed with a script in /usr/local/etc/rc.d you can either 944 hand-edit the rcvar= line, or reinstall the port. 945 946 An easy way to handle the mass-update of /etc/rc.d: 947 rm /etc/rc.d/* && mergemaster -i 948 94920120109: 950 panic(9) now stops other CPUs in the SMP systems, disables interrupts 951 on the current CPU and prevents other threads from running. 952 This behavior can be reverted using the kern.stop_scheduler_on_panic 953 tunable/sysctl. 954 The new behavior can be incompatible with kern.sync_on_panic. 955 95620111215: 957 The carp(4) facility has been changed significantly. Configuration 958 of the CARP protocol via ifconfig(8) has changed, as well as format 959 of CARP events submitted to devd(8) has changed. See manual pages 960 for more information. The arpbalance feature of carp(4) is currently 961 not supported anymore. 962 963 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 964 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 965 need to be recompiled. 966 96720111122: 968 The acpi_wmi(4) status device /dev/wmistat has been renamed to 969 /dev/wmistat0. 970 97120111108: 972 The option VFS_ALLOW_NONMPSAFE option has been added in order to 973 explicitely support non-MPSAFE filesystems. 974 It is on by default for all supported platform at this present 975 time. 976 97720111101: 978 The broken amd(4) driver has been replaced with esp(4) in the amd64, 979 i386 and pc98 GENERIC kernel configuration files. 980 98120110930: 982 sysinstall has been removed 983 98420110923: 985 The stable/9 branch created in subversion. This corresponds to the 986 RELENG_9 branch in CVS. 987 988COMMON ITEMS: 989 990 General Notes 991 ------------- 992 Avoid using make -j when upgrading. While generally safe, there are 993 sometimes problems using -j to upgrade. If your upgrade fails with 994 -j, please try again without -j. From time to time in the past there 995 have been problems using -j with buildworld and/or installworld. This 996 is especially true when upgrading between "distant" versions (eg one 997 that cross a major release boundary or several minor releases, or when 998 several months have passed on the -current branch). 999 1000 Sometimes, obscure build problems are the result of environment 1001 poisoning. This can happen because the make utility reads its 1002 environment when searching for values for global variables. To run 1003 your build attempts in an "environmental clean room", prefix all make 1004 commands with 'env -i '. See the env(1) manual page for more details. 1005 1006 When upgrading from one major version to another it is generally best 1007 to upgrade to the latest code in the currently installed branch first, 1008 then do an upgrade to the new branch. This is the best-tested upgrade 1009 path, and has the highest probability of being successful. Please try 1010 this approach before reporting problems with a major version upgrade. 1011 1012 When upgrading a live system, having a root shell around before 1013 installing anything can help undo problems. Not having a root shell 1014 around can lead to problems if pam has changed too much from your 1015 starting point to allow continued authentication after the upgrade. 1016 1017 ZFS notes 1018 --------- 1019 When upgrading the boot ZFS pool to a new version, always follow 1020 these two steps: 1021 1022 1.) recompile and reinstall the ZFS boot loader and boot block 1023 (this is part of "make buildworld" and "make installworld") 1024 1025 2.) update the ZFS boot block on your boot drive 1026 1027 The following example updates the ZFS boot block on the first 1028 partition (freebsd-boot) of a GPT partitioned drive ada0: 1029 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1030 1031 Non-boot pools do not need these updates. 1032 1033 To build a kernel 1034 ----------------- 1035 If you are updating from a prior version of FreeBSD (even one just 1036 a few days old), you should follow this procedure. It is the most 1037 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1038 1039 make kernel-toolchain 1040 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1041 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1042 1043 To test a kernel once 1044 --------------------- 1045 If you just want to boot a kernel once (because you are not sure 1046 if it works, or if you want to boot a known bad kernel to provide 1047 debugging information) run 1048 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1049 nextboot -k testkernel 1050 1051 To just build a kernel when you know that it won't mess you up 1052 -------------------------------------------------------------- 1053 This assumes you are already running a CURRENT system. Replace 1054 ${arch} with the architecture of your machine (e.g. "i386", 1055 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1056 1057 cd src/sys/${arch}/conf 1058 config KERNEL_NAME_HERE 1059 cd ../compile/KERNEL_NAME_HERE 1060 make depend 1061 make 1062 make install 1063 1064 If this fails, go to the "To build a kernel" section. 1065 1066 To rebuild everything and install it on the current system. 1067 ----------------------------------------------------------- 1068 # Note: sometimes if you are running current you gotta do more than 1069 # is listed here if you are upgrading from a really old current. 1070 1071 <make sure you have good level 0 dumps> 1072 make buildworld 1073 make kernel KERNCONF=YOUR_KERNEL_HERE 1074 [1] 1075 <reboot in single user> [3] 1076 mergemaster -Fp [5] 1077 make installworld 1078 mergemaster -Fi [4] 1079 make delete-old [6] 1080 <reboot> 1081 1082 To cross-install current onto a separate partition 1083 -------------------------------------------------- 1084 # In this approach we use a separate partition to hold 1085 # current's root, 'usr', and 'var' directories. A partition 1086 # holding "/", "/usr" and "/var" should be about 2GB in 1087 # size. 1088 1089 <make sure you have good level 0 dumps> 1090 <boot into -stable> 1091 make buildworld 1092 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1093 <maybe newfs current's root partition> 1094 <mount current's root partition on directory ${CURRENT_ROOT}> 1095 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1096 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1097 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1098 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1099 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1100 <reboot into current> 1101 <do a "native" rebuild/install as described in the previous section> 1102 <maybe install compatibility libraries from ports/misc/compat*> 1103 <reboot> 1104 1105 1106 To upgrade in-place from stable to current 1107 ---------------------------------------------- 1108 <make sure you have good level 0 dumps> 1109 make buildworld [9] 1110 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1111 [1] 1112 <reboot in single user> [3] 1113 mergemaster -Fp [5] 1114 make installworld 1115 mergemaster -Fi [4] 1116 make delete-old [6] 1117 <reboot> 1118 1119 Make sure that you've read the UPDATING file to understand the 1120 tweaks to various things you need. At this point in the life 1121 cycle of current, things change often and you are on your own 1122 to cope. The defaults can also change, so please read ALL of 1123 the UPDATING entries. 1124 1125 Also, if you are tracking -current, you must be subscribed to 1126 freebsd-current@freebsd.org. Make sure that before you update 1127 your sources that you have read and understood all the recent 1128 messages there. If in doubt, please track -stable which has 1129 much fewer pitfalls. 1130 1131 [1] If you have third party modules, such as vmware, you 1132 should disable them at this point so they don't crash your 1133 system on reboot. 1134 1135 [3] From the bootblocks, boot -s, and then do 1136 fsck -p 1137 mount -u / 1138 mount -a 1139 cd src 1140 adjkerntz -i # if CMOS is wall time 1141 Also, when doing a major release upgrade, it is required that 1142 you boot into single user mode to do the installworld. 1143 1144 [4] Note: This step is non-optional. Failure to do this step 1145 can result in a significant reduction in the functionality of the 1146 system. Attempting to do it by hand is not recommended and those 1147 that pursue this avenue should read this file carefully, as well 1148 as the archives of freebsd-current and freebsd-hackers mailing lists 1149 for potential gotchas. The -U option is also useful to consider. 1150 See mergemaster(8) for more information. 1151 1152 [5] Usually this step is a noop. However, from time to time 1153 you may need to do this if you get unknown user in the following 1154 step. It never hurts to do it all the time. You may need to 1155 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1156 install) after the buildworld before this step if you last updated 1157 from current before 20130425 or from -stable before 20130430. 1158 1159 [6] This only deletes old files and directories. Old libraries 1160 can be deleted by "make delete-old-libs", but you have to make 1161 sure that no program is using those libraries anymore. 1162 1163 [8] In order to have a kernel that can run the 4.x binaries needed to 1164 do an installworld, you must include the COMPAT_FREEBSD4 option in 1165 your kernel. Failure to do so may leave you with a system that is 1166 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1167 required to run the 5.x binaries on more recent kernels. And so on 1168 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1169 1170 Make sure that you merge any new devices from GENERIC since the 1171 last time you updated your kernel config file. 1172 1173 [9] When checking out sources, you must include the -P flag to have 1174 cvs prune empty directories. 1175 1176 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1177 "?=" instead of the "=" assignment operator, so that buildworld can 1178 override the CPUTYPE if it needs to. 1179 1180 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1181 not on the command line, or in /etc/make.conf. buildworld will 1182 warn if it is improperly defined. 1183FORMAT: 1184 1185This file contains a list, in reverse chronological order, of major 1186breakages in tracking -current. It is not guaranteed to be a complete 1187list of such breakages, and only contains entries since October 10, 2007. 1188If you need to see UPDATING entries from before that date, you will need 1189to fetch an UPDATING file from an older FreeBSD release. 1190 1191Copyright information: 1192 1193Copyright 1998-2009 M.
