 Recent changes:
 ^^^^^^^^^^^^^^^
 
+20180414:
+	Existing binutils was migrated to binutils.old.  Manual
+	removal of tools/binutils objects directory may be required
+	to fix tools build failure.
+
+20180311:
+	bdftopcf was updated and may need cleaning in the
+	src/external/mit/xorg/tools/bdftopcf subdirectory if there are
+	link errors.
+
+20180212:
+	between OpenSSL and GCC updates, many things may fail to build.
+	any failure that looks like GCC or openssl is best handled by
+	a clean destdir and objdir.  Full cleandir and destdir deletion
+	is recommended if build failures occur.
+
+20171225:
+	removal of the vadvise syscall requires manual removal of all
+	associated files from the libc build object directory (including
+	the .depend files) - a command like:
+		cd $OBJ && find . -type d -name libc | xargs rm -rf
+	For architectures that support multiple "compat" binary targets,
+	you'll need to cleanup both the regular libc directory and the
+	compat ones (the above command will do that).
+
+20171010:
+	a change to the build structure of external/bsd/acpica/bin/iasl
+	means that its objdir (or *.d and .depend at least) might need
+	to be manually removed - or a build done once without -u.
+
+20170822:
+	a new version of GMP has been imported and probably
+	will break parts of builds related to themselves or GCC, both
+	in the tools and the native section.  Remove all GCC, GMP, MPFR
+	and MPC objdirs or build once without -u.
+
+20170816:
+	a new version of MPFR and MPC have been imported and probably
+	will break parts of builds related to themselves or GCC, both
+	in the tools and the native section.  Remove all GCC, GMP, MPFR
+	and MPC objdirs or build once without -u.
+
+20170402:
+	a new version of dhcpcd has been imported, which does not support
+	update builds from the previous version. Remove your
+	external/bsd/dhcpcd object dir or build once without -u.
+
+20170211:
+	a new terminfo database has been imported.
+	The structure of it has changed slightly from prior versions and
+	an updated tic tool is required.
+	If you build.sh, don't use -u
+
+20170207:
+	various arch dependent libc/exect.S files were removed
+	Either remove the obj directories (lib/libc and compat/amd64/i386/lib
+	if it exists) or do a clean build.
+	(This is a bug in the make system, it should be corrected without
+	human intervention, but isn't.)
+
 20170104:
 	xinput build options have changed.
 	Remove the obj directory (external/mit/xorg/bin/xinput)
