GCC 5.5 Will Come Before Killing Off GCC5

Red Hat's Jakub Jelinek has announced that GCC 5.5 will be released soon.

Jakub is planning to do a release candidate of GCC 5.5 at the end of next week followed by the official release. This will mark the end of the GCC 5 series.

GCC 5 has remained open for bug fixes even though GCC 7 is the current stable series, GCC 6.x continues being maintained too, and GCC 8 is the version under development for release next year. GCC 5.5 will be the final step before GCC 5 is no longer maintained.

So if you still rely upon GCC 5 in production and there are any fixes you need to see backported, now is your time to act. More details in this mailing list post.
