Nova/ReleaseChecklist

This page is for tracking things that we should be doing in the code before or after each release.

Merge latest translations
Bump rpc major versions. See RpcMajorVersionUpdates
If products drop out of support, or have stopped being tested, we should ensure we warn users, so we have the option to remove them in the following release, if needed.
Ideally add the RPC version alias just before opening the next release
Add a reno 'prelude' section describing the most important changes in the release
Make sure there are no *-rc-potential bugs in launchpad, or anything that was an rc-potential bug is properly deferred.

Add database migration placeholders to allow backportable DB migrations
Drop old rpc compat code. See RpcMajorVersionUpdates
Update version aliases for rpc outbound version control. For example, the Newton RPC aliases were added in Ocata: https://review.openstack.org/#/c/386625/
