Recent changes: ^^^^^^^^^^^^^^^ +20120319: + sys/conf/Makefile.kern.inc has been modified to adjust the + size of db_symtab automatically. You need to update dbsym in + your $TOOLDIR to build kernels with options SYMTAB_SPACE. If + you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your + mk.conf. + +20120216: + Default for MKCATPAGES changed to NO. Update builds will fail + unless DESTDIR is cleaned manually. If you built between 20120207 + and 20120216, daily and weekly could have created an unreable + /var/db/man.db index for apropos. Running makemandb -f or + the next run of weekly will fix it. + +20111227: + If you built between 20111225 and 20111227 you need to remove + /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the + bump has been reverted. + +20111125: + The "rnd" pseudodevice has been added to sys/conf/std, which + means it should no longer be explicitly listed in kernel + configuration files. The line "pseudo-device rnd" should be + removed from any custom kernel config files users may have. + +20111119: + A problem with the datastructures used by the rndctl(8) + utility (pointers in datastructures in an array, making 32->64 + bit compatibility very painful) has been fixed in a + non-backwards-compatible way. If you replace your kernel, + replace your rndctl executable too. + +20111001: + the prop_*_send_syscall() functions from proplib(3) have been + changed and their new version is not backward compatible with the old + one. So ensure that all consumers of these functions (currently: + quota2 code and its tests) are updated together with the new lib. + +20110817: + sparc has been changed to use GCC 4.5.3, so any objdir or + DESTDIR for them should be deleted before updating. + +20110806: + i386 and amd64 have been changed to use GCC 4.5.3, so any + objdir or DESTDIR for them should be deleted before updating. + +20110805: + The update to GCC 4.5.3 requires a non-trivial portion of + the tree to be cleaned. Best to delete both objdir and + DESTDIR before running this update. So far, only the + sparc64, mips and powerpc platforms have changed. + +20110803: + The layout of external/public-domain/xz has changed. To do an + update build you will have to remove the contents of the OBJDIR + for external/public-domain/xz/bin by hand as the xz entry there + is now a directory. + +20110410: + The configuration of src/tools/gcc has changed. To do an + update build you have to clean both tools/binutils and + tools/gcc by hand. + +20110328: + Building the Xorg binary was moved into a subdirectory to fix + ordering issues with "make all". It may be necessary to remove + the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86 + if your update build fails, as the "Xorg" entry there is now a + directory. + +20110121: + Assembler files no longer use -traditional-cpp. This can break + the build of individual parts of the tree. This is handled + correctly by build.sh. Manual builds have to update /usr/share/mk + and re-run config(1) for any kernel configurations as needed. + +20101217: + The tcpdump(8) program was changed to drop privileges and chroot(2) + by default. It may be necessary to manually update passwd(5) and + group(5) in order to make the program work with existing setups. + +20101125: + The latest changes to setenv(3) dissallow setting environment + variables with names that contain '='. Revision 1.18 of env.c + assumed that this was allowed. Installing a new libc with an + old copy of /usr/bin/env causes env x=1 printenv | grep x= to + break which affects the autoconf tests for dependency finding, + so building gcc will end up printing: + checking dependency style of gcc... none + configure: error: no usable dependency style found + Fix it by rebuilding and re-installing env. + +20101119: + Recent Xorg updates in xsrc/external/mit/ may cause various build + or run-time problems. Delete your entire DESTDIR and OBJDIR if you + have any build problems with xsrc, or problems with mismatched + versions between xorg-server and drivers. + +20100604: + The update of ATF to 0.9 causes old tests written in shell to fail + unless they are rebuilt. If you are building with MKUPDATE=yes, + you need to clean the src/external/bsd/atf/tests/ and the src/tests/ + trees by hand. + +20100522: + Recent Xorg updates in xsrc/external/mit/ will cause various build + problems. Delete your entire DESTDIR and OBJDIR if you have any + build problems with xsrc. + +20100522: + private section of was splitted, and now mklocale(1) + include ctype_local.h, so you have to make cleandir in tools/mklocale. + +20100520: + The location of the xkb compiled descriptions has changed.

All now stale regular .so files can be removed from + your object directories. + +20100204: + The termcap database has been removed from the sources, + but has not been marked obsolete so it is not removed + from the system when upgrading. + As such, you will need to remove them from your object + and destination directories. + +20091101: + After updating, it may be necessary to make the 'cleandir' + target in src/tools/yacc/ and in src/usr.bin/yacc/ before a + 'build.sh -u tools' or 'build.sh -u distribution'.
