Subject Re: Moving forward on AURORA-1503

It seems that this is not a correct usage of semver and that we should
release the link to 0.23.0 as 0.10.0. Given the mesos deprecation cycle
described in that ticket, 0.22.0 would be compatible with 0.21.0. IMO a
patch release should never break compatibility with versions that the
previous patch version worked with - it should be for things like
showstopper security or reliability bugs.

I'd be +1 to releasing a 0.10.0 that contains only the patch changing our
link target to 0.23.0 and pushing our next "feature release" to 0.11.0.
