-20140131:
-	The new compile_rt/libc integration moved a few things. If not
-	starting with a clean objdir, cd to the objdir and do:
-		rm -rf lib/libc
-	and if you are on a 64bit arch with 32bit compat, additionally:
-		rm -rf compat/sparc64/sparc/lib/libc
-	(substitute proper archs for sparc/sparc64)
+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.

@@ -668,3 +707,13 @@ Fix:    May need to build & install libs
 Symptom:Update build fails in src/tools/gcc complaining that a variable
 	(e.g. CPPFLAGS) has changed since the previous run.
 Fix:    Run "nbmake-${ARCH} clean" in src/tools/gcc or do a clean build.

+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.
