 `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 2.x version
-* `2.13` and `2.12` are for backported fixes for 2.13/2.12 versions (respectively)
+* `2.19` is for developing the next 2.x version
+* `2.18` and `2.17` are for backported fixes for 2.18/2.17 versions (respectively)
