Google’s VP of Android Product Management, Hugo Barra, tweeted today that his company has posted the updated Jelly Bean changelog, a list of all the new stuff in the Jelly Bean version of the Android operating system since 4.1, just in time for 4.2.2 to roll out.

Some of those changes include Google Now, Photo Sphere, Gesture Typing, and Project Butter, along with a host of other changes, like triple tapping in the center of the screen to magnify when Magnification gestures are enabled, improved Wi-Fi Direct support, a brand new photo editor with new filters, borders, and other tools, and a host of accessibility improvements as well.

This changelog is posted now, not too log after Android 4.2.2 started hitting Nexus devices, and includes some features like the long press on WiFi and Bluetooth icons in the Quick Settings to toggle the features on or off.

From the changelog

Android 4.2, Jelly Bean improves on the speed and simplicity of Android 4.1 and includes all new features – Photo Sphere and a completely redesigned camera app, new Gesture Typing keyboard, Google Now with all new cards, and much more.

• Everything in Jelly Bean feels fast, fluid, and smooth. Moving between home screens and switching between apps is effortless, like turning the pages of a book.
• Jelly Bean improves performance throughout the system, including faster orientation changes, quicker switching between recent apps, and smoother and more consistent rendering across the system through vsync and triple buffering.
• Jelly Bean has more reactive and uniform touch responses, and makes your Android device even more responsive by boosting your device’s CPU instantly when you touch the screen, and turns it down when you don’t need it to improve battery life.

For full details, head on over to the posted changelog.
