That is an ambitious agenda and I sincerely wish you the best on pulling
it together.
Not sure if these are already covered as sub-points
- Minor version upgrades vs major version upgrades
Make clear that the version numbering that distinguishes this is
changing with version 10.

A new point.

someone went from using a self compiled version to one from a package or
pulled from different repos.
