 Recent changes:
 ^^^^^^^^^^^^^^^
 
+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)
+	if you build.sh -u
+
+20170103:
+	a new version of flex has been imported.
+	Remove the file from obj (external/bsd/flex)
+	if you build.sh -u
+
+20161014:
+	a new version of OpenSSL has been imported.
+	Remove the files from obj (crypto/external/bsd/openssl) 
+	if you build.sh -u
+
+20161009:
+	a new version of dhcpcd has been imported with slightly changed
+	build infrastructure. When doing a build.sh -u this requires
+	pruning the external/bsd/dhcpcd objdir.
+
+20160914:
+	i386, amd64, shark, ofppc and macppc have joined shark and x68k
+	ports in using xorg-server 1.18. This requires a clean destdir
+	and a clean objdir.
+
+20160527:
+	i386 needs a full cleandir or objdir deletion because PIE has
+	been enabled. (see the amd64 entry two down for further info)
+
 20160418:
 	libedit needs manual removal of all autogenerated files since
 	some of them are not autogenerated anymore. Remember that there
