[Nook Color Android Development] eyeballer:
Team Win Recovery Project 2.3, or twrp2 for short, is a custom recovery built with ease of use and customization in mind. It’s a fully touch driven user interface – no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

CHANGELOG for 2.3.1.0:

-Unmount system after boot to prevent some status 7 symlink failed errors on zip install

-USB Mass Storage code improvements

-Better handling of mounting storage during boot for some devices

-Fixed a problem with sizes of images (boot & recovery) after resetting defaults

-Fixed size errors during backup for some devices on recovery, etc.

-Fixed a problem with restoring backups when multiple archives were present

CHANGELOG for 2.3.0.0:

-Rebased onto AOSP Jelly Bean source code

-Rewrote backup, restore, wipe, and mount code in C++ classes for easier maintenance going forward

NOTE: backups from prior versions of TWRP are still compatible with 2.3

-ADB sideload functionality from AOSP is included in 2.3, see this link for more info

-Re-wrote fix permissions entirely in C++ and runs in a few seconds instead of a few minutes (thanks to bigbiff)

-Improvements to zip finding in OpenRecoveryScript (should be a lot fewer GooManager automation issues)

-Faster boot times

-Added charging indicator while in recovery (only updates once every 60 seconds)

While this update may not bring a host of new must-have features, this update is a significant re-write of much of the core TWRP code. AOSP Jelly Bean recovery source moved to mostly C++ code and now all of the "TWRP" code is fully rewritten into C++ as well. Now that we've laid this groundwork, we're in a much better position to pull in future AOSP recovery updates as well as implementing more great new features.

Since TWRP 2.3 is based on AOSP jelly bean sources, TWRP now uses recovery API 3 instead of 2. Some zips may no longer work if the developer is using an out-of-date update-binary. This API change should not be a problem on newer devices, but older devices will probably encounter several zips that need to be updated. If needed, you can try using this update-binary that was compiled with current sources. It goes in your zip file in the META-INF/com/google/android folder.

BUGS:

If you have found a bug, please consider posting it to our github issues log. It's pretty much impossible for us to keep up with the more than 30 threads that we have for the devices that we "directly" support. If you have a significant problem that cannot be answered in this thread, your best bet is to PM me directly, contact us via our website, or find us in our IRC channel below. If you see someone that's struggling, feel free to point it out to us. We need your help to help us keep track of all of our devices! Thanks!
