Aside from OpenJPEG, lots of stuff in this release, including
With line-specific correcting in the 0.9 release, you can find out which lines actually run into such problems, and tell Emscripten to generate the 100% correct code only in them. Most of the time, the slow and correct code isn't needed, so this option is very useful. I will write a wiki page soon to give more examples of how to use it to optimize the generated code (meanwhile, check out the linespecific test).
- 20% faster compilation, mainly from optimizing the analyzer pass.
