 ^^^^^^^^^^^^^^^  ^^^^^^^^^^^^^^^
   
   20160418:
           libedit needs manual removal of all autogenerated files since
           some of them are not autogenerated anymore.
   
   20160410:
           amd64 needs full "make cleandir" or deletion of objdir now that
           PIE has been enabled for amd64.  PIE, or position-independent
           executables, means all code, including executables and not just
           shared libraries, is position-independent and hence able to be
           relocated by ASLR, address space layout randomization.
   
           The change was made in Makefile variables for compiler and
           linker flags, for which make(1) does not record dependencies,
           hence it is unable to detect that all .o files need rebuilding.
   
           Partial rebuilds with some modified source files will likely
           fail when linking executables, since the linker refuses to mix
           position-independent code with position-dependent code in
           position-independent executables:
   
                   .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
   
   20160401:
           Ports switching to GCC 5.3 will need a full "make cleandir".
           Some people have found that cleandir is not sufficient, so if
           in doubt delete the entire object directory tree for gcc.
   
   20160306:
           NetBSD's regexp implementation is now part of libnbcompat.
           Nblex, nbm4, nbpax, nbsed use it and they may crash on
           non-NetBSD hosts if linked with stale object files produced
           while they included a non-NetBSD regex.h.
           In any case, you should "make cleandir" at least these tools
           before updating your toolchain.
   
   20160125:
           Dtrace has been enabled by default on some architectures.
           When doing an update build, make sure to clean the etc/mtree
           object directory before starting the build - otherwise the
           needed directories in destdir will not be created.
           An easy way to do this is:
              cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
   
   20150818:
           New acpica requires "make cleandir" in src/external/bsd/acpica
           again.
   
   20150413:
           New acpica requires "make cleandir" and reinstalling yacc
           in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
           also "make cleandir" in /usr/src/external/bsd/acpica.
   
   20150404:
           Lint changes require a full rebuild of the tool, so make
           sure to build without -u option to build.sh, or manually
           do a make cleandir in src/tools/lint1 and
           src/usr.bin/xlint.
   
   20150310:
           Improvements to openssl for arm mean that update builds of
           the openssl libraries will fail. A make cleandir in
           external/bsd/openssl/lib is needed
   
   20141026:
           A mishap during the import of pppd may cause your corruption
           in your cvs directory if you happened to do a cvs update
           during a short period of time. To fix, just remove the
           directory src/external/bsd/ppp/dist/pppd completely
           and let cvs restore it on next update.
   
   20140721:
           The src/external/mit/lua/src directory was accidentally created
           and then deleted in the CVS repository.  If you get errors like
   
           cvs [update aborted]: cannot open directory
           /cvsroot/src/external/mit/lua/src: No such file or directory
   
           then delete your local copy of that directory tree and try again.
   
   20140530:
           ARM eABI switched to DWARF based exception handling. This requires
           rebuilding all C++ code. It is strongly advised to do a clean build.
   
   20140131:
           The new compiler_rt/libc integration moved a few things. It is strongly
           advised to do a clean build. At least lib/libc, the compat version(s)
           of libc, libkern, rump and the kernels need to be cleaned.
   
   20131227:
           1. The new ntpd runs in a restricted mode to prevent amplification
              attacks. If you need ntpdc to work you need to explicitly enable
              mode7 in your config file. Make sure you put the necessary restrict
              statements to avoid being exposed.
           2. strncat has moved from lib/libc to common/lib/libc; you might need
              to make clean in libc
   
   20131129:
           The GMP sources were updated, and builds will likely fail without
           cleaning their build trees for both tools and in-tree, like below.
   
   20131128:
           The MPC and MPFR sources were updated, and builds may require their
           tools and in-tree directories cleaned for successful updates.
   
   20130605:
           The kernel option FAST_IPSEC no longer exists, it's been renamed
           to IPSEC (and the older IPSEC version removed).
   
   20130605:
           Previous freetype installations eroneously installed private
           header files. If you are building against a non-empty $DESTDIR,
           please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/.
   
   20130531:
           The xdm update may cause build failure due to xdm.man being
           in the obj tree.  Make sure to ensure any like this:
                   nbmake: nbmake: don't know how to make xdm.man. Stop
           is fixed by deleting the xdm.man in the obj tree.
   
   20130530:
           Updates of many xsrc packages will leave old .pc files around.
           Best to clean out the xsrc objdir entirely before rebuilds.
   
   20130301:
           The removal of netiso requires manual removal of /usr/include/netiso
           prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump}
   
   20120726:
           The update of OpenSSL requires cleaning both the OpenSSL build
           directory and DESTDIR.  *Even non-update builds require cleaning
           DESTDIR.* Builds done without taking these steps may fail, or in
           some cases may succeed and install broken OpenSSL libraries that
           cause third-party software to link incorrectly and/or crash.
   
   20120507:
           The database schema for makemandb was changed.  You will
           need to update the database using 'makemandb -f' or wait
           for the next weekly run to fix it.
   
   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 unreadable
           /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 <ctype.h> 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.  Please
           remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR.
   
   20100222:
           The shared objects file extension has been changed from .so to
           .pico, in order to avoid conflicts with shared libraries names
           libXX.so.  All now stale regular .so files can be removed from
           your object directories.

   Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
           No such file or directory.
   Cause:  If a directory is created by mistake, then it is sometimes
           deleted from the CVS repository using administrative commands
           that bypass the normal cvs access controls.  If your cvs working tree
           contains references to a directory that has been deleted on the
           server in this way, then "cvs update" reports this error.
   Fix:    Recursively delete the affected directory from your working tree
           and try the update again.
