Seas0nPass has been updated to support a tethered jailbreak of the new AppleTV 4.2 (iOS 4.3) software. Big thanks to @nitoTV, @DjayB6, @p0sixninja and @msft_guy for help getting everything together.
What's new in AppleTV 4.2? Should I update?
- AirPlay for apps and websites
- MLB.TV & NBA Game Time live streaming
- Netflix Dolby Digital 5.1
- Other minor improvements and fixes
If you choose to update to the new version you will lose your current jailbreak and aTV Flash (black) plugins.
If the above features don't excite you the auto-update feature can be disabled through the Maintenance --> Settings menu.
Is aTV Flash (black) Beta3 compatible?
For the most part yes. However, you may see a few oddities with text entry screens in plugins like Couch Surfer and nitoTV. These are relatively minor issues and should be a quick fix.
Update 3/11: New 4.3 compatible versions of Couch Surfer and Last.fm are now available.
Additionally there are some hardware decoding issues present in XBMC which will take a bit more work to get right.
The updated version, and user guides can be found at Seas0nPass.com
