During the Boston Summit education session there were
questions about stable branches during the 'Release Cycle'
presentation. We decided it would be good to add slides for
this to that presentation.
This patch adds those slides. Also, it appears that the way
that ReST is processed by the latest tooling is slightly different.
If you don't have spaces before and after an indented section it
doesn't indent the bullets. This patch fixes that for this
set of slides as well.
There was also some awkward wording that was caught in review.
This fixes those issues as well.
