Drop the notes about listing all the github issues with the release
notes. That was a huge list of github issues sorted by closing time,
very noisy and hard to maintain.
The unfiltered list of changes is already in the commit history, a
distilled list is now in the blog posts and a final list is in the notes
summary.
The issue list has been skipped in 3.4 already, let's just drop it from
the process.
