Red Hat's Nick Clifton has written a lengthy update concerning the state of the GNU Toolchain as we near the end of the first quarter, 2017.

GNU tooling updates we have seen recently include GLIBC 2.25, GDB 7.12.1, Newlib 2.5, GCC 6.3, GCC 7 nearing release, and Binutils 2.28.

While we have covered most of the changes individually to these GNU toolchain components, if you want a synopsis of what's been happening to the GNU compiler stack, see this mailing list post for the quarterly write-up by Clifton.
