## New\r
\r
-- Added APIDumpFile to write APIDump directly to a file\r
-- Added MemTracker validation layer\r
-- Added various turn-on tests for variety of driver / compiler features\r
-- Fix to wsiPresent to avoid deadlock with X server\r
-- Misc. fixes to layers and Intel sample driver\r
+- Added mutex to APIDump, APIDumpFile and DrawState to prevent apparent threading issues using printf\r
+- Fix support for {Fill,Copy}Memory\r
+- MemTracker can report issues to application via debug callback\r
+- Update test infrastructure to improve ease of writing new tests. Add image comparison feature for regression testing. Requires ImageMagick library.\r
+- Misc. fixes to demos, layers and Intel sample driver\r
