TWRP 2.4 is out. Easy way to install is via
Goo Manager (menu... install open recovery script)
CHANGELOG for 2.4.0.0:
-Using libtar instead of busybox's tar for better control over tar file creation and breaking the 2GB barrier that busybox imposes (thanks to bigbiff)
-Support for exFAT formatted sdcards (also thanks to bigbiff)
-Support for decrypting Samsung TouchWiz encrypted devices including internal and external storage (special thanks to a3955269 for figuring it out)
-Improvements to OpenRecoveryScript including displaying a proper GUI while the script is running
-Added wipe cache and dalvik after ADB Sideload
-Replaced many system calls with their native C counterparts
-Fixed bugs in file manager where it would display an empty list after moving or deleting a folder
-Fixed AOSP recovery commands to run after decryption on encrypted devices
-Improvements for building TWRP in CM10.1
-Other minor bugfixes and improvements
NOTE: 2.4.0.0 is, as always, still compatible with your older backups!
