 ## Branches
 
 `master` branch is for developing the next major Jackson version -- 3.0 -- but there
 are active maintenance branches in which much of development happens:
 
-* `2.14` is for developing the next minor 2.x version
+* `2.15` is for developing the next minor 2.x version
+* `2.14` is for backported fixes to include in 2.14.x patch versions
 * `2.13` is for backported fixes to include in 2.13.x patch versions
-* `2.12` is for backported fixes to include in 2.12.x patch versions
 
 Older branches are usually not changed but are available for historic reasons.
 All released versions have matching git tags (`jackson-dataformats-text-2.9.4`).

 ## Android quirks
 
 Usage of this library on Android is currently not supported. This is due to the fact that the Stax API is unavailable on the Android platform, and attempts to declare an explicit dependency on the Stax API library will result in errors at build time (since the inclusion of the `javax.*` namespace in apps is restricted).
