+=========================
+Airflow's release process
+=========================
+
+Since Airflow 2.0.0 the release numbering works as follows:
+
+- Versions are numbered in the form X.Y.Z.
+- X is the major version number.
+- Y is the minor version number, also called the *feature release* version number.
+- Z is the patch number, which is incremented for bugfix and security releases- Before every new release, we’ll make a release candidate available, and often alpha or beta release too. These are of the form X.Y.Z alpha/beta/rc N, which means the Nth alpha/beta/release candidate of version X.Y.Z
+
+In git, each minor version will have its own branch, called ``vX-Y-stable`` where bugfix/security releases will be issued from.
+
+Each Airflow release will also have a tag in git indicating its version number, signed with the release manager's key. Additionally, each release series has its own branch, called stable/A.B.x, and bugfix/security releases will be issued from those branches.

Review comment:
       Yep. Signed tags for releases!
