This is the first release candidate in preparation for the upcoming 2.17.0 release. We will appreciate any feedback we can get from testing of this snapshot.
The basis of this release are to push out a couple of critical stability fixes for SandyBridge and IvyBridge. There is very little else to see here. Those 200+ other commits do not exist... -Chris Bugs fixed in this snapshot (compared to 2.16.0) -------------------------------------------------- * Workaround blitter hang on SandyBridge and
