2. 2013 Recap
 Initial implementation shipped with IE11
 Simple goals
 Security
 Interoperability
 Breadth
 API support mainly limited by time

3. Product feedback
 Most common feedback is about feature gaps
 Trying to release aggressively to fix this
 Next most common is performance
 Fallback because of drivers #1 issue
 Hardware diversity is a challenge
 Some feature gaps too
 A lot of great feedback overall
 Some great partners helping out (AGI, Google)

4. Release progress
 IE11 RTM in Aug 2013
 IE11 GA in Oct 2013
 D3D10 level feature support
 IE11 S14 in April 2014
 Compressed textures
 Standard derivatives
 Much much more
 IE11 Update 2 shipped yesterday!
 Instancing extension
 Fan / loop primitive support
 S14 equivalent shipping in preview on WP8.1 now

7. Demos
 Vill.ee eye
 Photosynth
 Google maps

8. Security
 Expanding capabilities only as needed
 Pass conformance test
 Meet site expectations
 Still some shader restrictions
 Instruction limits still there, but relaxed
 Still no loops that cannot unroll
 No changes to software fallback
 Drivers remain a challenge

9. My WebGL *still* does not
work in IE!
 Are you running the latest IE11 (v 0.94)
 Have you tried the preview?
 Can your hardware run it?
 IE11 cannot access some D3D9 features
 Error messages have been enhanced
 If they are not good enough, let us know!
 We still have some missing features
 Feedback about ordering is still very helpful

10. Looking forward
 Still more conformance work ahead
 Preview builds should help see this
 Continue to evolve the standard
 More conformance tests
 More extensions
 We welcome feedback
