What's new in 2.7.1.0:
Add GUI option to change or repair file systems on individual partitions. The change is destructive so backup your data including internal sdcard first. This option should make it a little easier to migrate a device from ext4 -> f2fs, for instance. You will find this option under Wipe -> Advanced Wipe, then select only one partition and then press the Repair or Change File System button. If a developer has added f2fs support for your device and we don't have it in TWRP, please contact me via PM to arrange for it to be added.
