New features I've uncovered:
• CoreGraphics to PDF API for sure, printer API is being prototyped
• Spell checker in text fields and web views using AppleSpell
- multiple languages
- grammar checking (English-only so far)
- address book integration
- user added words
- SDK access
- Included dictionaries: Apple Dictionary, New Oxford American Dictionary, Oxford American Writer's Thesaurus, Shogakukan Daijisen, Shogakukan Progressive English-Japanese Japanese-English Dictionary, and Shogakukan Ruigo Reikai Jiten (may also be used for a Dictionary app perhaps?)
• USB Host support or expanded Bluetooth support
- PTP support for transferring images
- MobileStorageMounter (perhaps used for PTP; perhaps used to mount external USB storage?)
- Hardware keyboard: USBKeyboardLayouts.plist
• Much richer text API including low-level access to font data and highlevel support for drawing formatted text
• Support for querying attached screens and choosing which screen a window draws on (App Store approved?)
• The beginnings of file upload in Safari
• Location-sensitive ads are being prototyped in integrated Maps application (and applications that use the maps framework)
• Ability for applications to modify the standard cut/copy/paste menu
• "Handwriting keyboard" is being prototyped.
