The Team Win Recovery Project has released version 188.8.131.52 of its custom recovery, known simply as TWRP. This update brings a system read-only option that's intended to help you make a pure backup of your system image that you can later flash to receive over-the-air updates after having rooted or ROMed your device.
Android 5.0 devices and higher check the system partition to see if it has ever changed from read-only to read/write. Users can now opt to install TWRP as read only. It then won't prompt to install SuperSU, nor will it patch your ROM to prevent itself from being replaced with the stock recovery.
184.108.40.206 also brings a resize2fs feature that lets you resize your data partition to use your full amount of available memory in those cases when you flash a factory image intended for a 32GB device to a 64GB one.
