  • 14. heavily-requested features →Other ↑Alpha channel in PNG images ↑“Native” XMLHTTPRequest the Programming Experience →Improved ↑Improved JavaScript GC performance ↑Fixed some major memory leaks ↑Fixed Caching of gzipped files 14
  • 15. “I’m really concerned that we’re breaking stuff in the name of goodness and that all users and developers will walk away with is ‘stuff broke.’” 15
  • 16. → Compatibility is critical adoption/deployment factor → We must balance compliance with site compatibility → In IE7, “quirks mode” stays the same - most standards changes are only in “strict mode” → Unfortunately,standards mode is increasingly popular, and developers expect behavior to not change – except when they want it to 16
