News and articles from around the web

LLVM/Clang 3.9 has now branched. A first release candidate should be available shortly. As you may recall there was a very long mailing list discussion about what the successor to 3.9 would be. In the end, it was decided it should be 4.0.

As a reminder, I am organising a one-day LLVM conference the LLVM Cauldron to be held in Hebden Bridge, UK on September 8th. This is immediately followed by the GNU Tools Cauldron. The submission deadline is August 8th, so get your talk proposals in now.
