 Recent changes:
 ^^^^^^^^^^^^^^^
+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

 Symptom:lint does not understand the '-X' option
 Fix:    May need to build & install libs with NOLINT=1 before rebuilding lint

+Symptom:Update build fails in src/tools/gcc complaining that a variable

+Fix:    Run "nbmake-${ARCH} clean" in src/tools/gcc or do a clean build.
