GCC 5 was formally released this week with under their new versioning scheme the initial stable release being GCC 5.1. GCC 6.0 is now in development as the next major release due out in about one year's time while the next GCC 5 point release will be GCC 5.2.

The point release / stable update to GCC 5.1 isn't going to be GCC 5.1.1, but that's the version right now reflecting the post-5.1's release development state. When this next release is ready, it will be called GCC 5.2.0.

Jakub Jelinek of Red Hat issued the first GCC 5.1.1 status report this week on the GCC mailing list. For those interested, Jakub feels the GCC 5.2 stable update will be ready for release in two to three months. However, if any urgent issues are uncovered, GCC 5.2 could happen before that.
