An update to the DirectX SDK is now available. Here is a brief list of changes:
PIX - Call capture and playback, Asynchronous events, Triggers and Actions
Maya Exporter - Maya 6 Support, Procedural texture support, Updated installer
C++ - AntiAliasing, Instancing, ConfigSystem
Managed - PrtPerVertex, FragmentLinker , SimpleAnimation
D3DX - Debug Output Muting, PRT Blocker meshes no longer have a 65,535 vertex limit, texture UV coordinate transformation)
DirectX for Managed Code - memory leak in TextureLoader.FromFile, unhandled exception errors)
I am especially excited about the Maya 6 exporter. The last SDK only included support for Maya 5 and it didn't work with the new version.
Here are the links to the downloads. This is "breaking" news, so the main portal page, http://msdn.microsoft.com/directx, hasn't been updated yet.
