New features and improvements:

• Fix AMD GPU DCE-8+ display engine handling on Linux and OSX. Latest generation AMD gaphics cards are now fully supported.
• Fix OSX PsychtoolboxKernelDriver multi-display handling bugs introduced by the “Puking Rainbow Unicorn” beta.
• Improve 10 bpc pixelformat selection for OSX for native 10 bit framebuffer support. Untested due to lack of iMac 5k hardware.
• Minor bug fixes and documentation updates in various places.
• OSX: Maybe improve detection and handling of USB-DAQ devices. PsychHID for OSX may now support USB device selection by HID interfaceID, which might improve robustness of USB-DAQ detection and DaqAInScan functionality. Completely untested due to lack of hardware.
• Windows: Improve visual stimulus timing on Windows-10, and maybe on Windows 8/8.1 (untested). On a Windows-10 test system with a 5 year old AMD Radeon HD-5770 this makes visual stimulation timing and timestamping work ok, despite the DWM being permanently enabled. More tests are needed, but this might allow at least basic use of Windows-10.
