Fork of TWRP

This fork differs from the original in the following ways:

• Designed to be built with CyanogenMod 13.0 only
• Require fstab v2 syntax (see examples and supported flags below)
• Use external repositories for pigz, exfat, fuse
• Power key toggles screen on/off
• Remove the need to specify either DEVICE_RESOLUTION or TW_THEME so long as TARGET_SCREEN_HEIGHT and TARGET_SCREEN_WIDTH are set
• Other minor customizations (see change history)

Versioning

To help distinguish builds of recovery made from this fork, the minor version digit is replaced with M#. Minor version increments will be handled as needed, independent of TWRP. The major and semi-major version digits follow upstream to roughly indicate feature parity (as close as possible with a fork, anyways).

Convention:

• 3.0.M0-0 incorporates all major features from TWRP 3.0.0-0
• 3.0.M1-0 is the minor version increment after 3.0.M0-0 and is independent of any TWRP minor version increment(s)
• 3.1.M0-0 is the semi-major version increment after 3.0.M4-2 and is tied to a TWRP semi-major version increment
• 3.0.M0-1 is a device-specific fix to 3.0.M0-0; this device digit resets when any other version increments

Examples of fstab v2 for TWRP

Example fstab v2 for device mt2:

Worth noting in this example: encryptable= does not need to be specified if encryption keys are stored at the footer of /data. This is the default, assumed location.
