The liberty, mitaka, and newton branches are closed so there is no
reason to scan for release notes dynamically. Use static content for

We had 14.0.0 for Newton but weren't specifying these
for Liberty, Mitaka or Ocata release notes.
The Liberty tag starts at 12.0.1 since that's the first
tagged release in the stable/liberty branch where we
started using reno:
5207013fddd296d062d1f375dfafde382a98f92d
