Relnotes usually have a gccgo subsection in the Tools section explaining how's gccgo doing and what version to expect in the next release (e.g. http://tip.golang.org/doc/go1.8#gccgo, http://tip.golang.org/doc/go1.7#gccgo, http://tip.golang.org/doc/go1.6#gccgo). Currently missing from the 1.9 relnotes.

https://github.com/golang/go/issues/21289 - crypto/x509 change I believe is missing, though it's probably too late now...
