Just a quick heads up to all library, package, documentation, and
translation developers, barring any unexpected critical bugs I will be
tagging stable release version 6.0.1 late on Tuesday, January 11 (EST)
for official release on January 15th. If you have anything you want to
push before 6.0.1, now would be a good time.
