Note that the new versioning proposal starts to land in projects, so
you may need a series of fixes to add epochs to your server packages.

F.e. see neutron series in delorean:

Those patches were all failing because of semver rules enforced by
pbr.  The fix is to add a version tag for an earlier version (that
is, to make the 1.0.0 version change in setup.cfg work we need a
1.0.0a0 tag). I'm starting to push those tags today, and I will be
rechecking the setup.cfg updates as I do.

If you start seeing unexpected versions appear in your local sandbox,
the tags are why. I don't expect that to cause issues with any local
builds, but if you see problems start by rebuilding your tox
virtualenvs.

We did identify one potential issue with heat's reliance on its package
version for indicating deprecations and supported features. I'll be
waiting to make any of these changes to heat until I've had a chance to
confer with the core team about the best approach for ensuring the
version change won't cause issues.

Doug
