The first release candidate for the second release from the GCC 6 branch, GCC 6.2.0, from SVN revision r239476, is available from
ftp://gcc.gnu.org/pub/gcc/snapshots/6.2.0-RC-20160815/ and shortly its mirrors. I have so far bootstrapped and tested the release candidate on x86_64-unknown-linux-gnu. Please test it and report any issues to bugzilla. If all goes well, we'd like to release GCC 6.2.0 early next week.
