Just like Ubuntu itself, upstream releases long term support releases, as is 2.0 and then periodic point releases including all the accumulated bugfixes.

Only the latest upstream release gets full support from the upstream
developers, everyone else is expected to first update to it before
receiving any kind of support.

This should qualify under the minor upstream bugfix release allowance of
the SRU policy, letting us SRU this without paperwork for every single
change included in this upstream release.

Once the SRU hits -updates, we will be backporting this to trusty-
backports as well, making sure we have the same version everywhere.

  Just like Ubuntu itself, upstream releases long term support releases, as is 2.0 and then periodic point releases including all the accumulated bugfixes.

  Only the latest upstream release gets full support from the upstream
  developers, everyone else is expected to first update to it before
  receiving any kind of support.

  This should qualify under the minor upstream bugfix release allowance
  of the SRU policy, letting us SRU this without paperwork for every
  single change included in this upstream release.

  Once the SRU hits -updates, we will be backporting this to trusty-
  backports as well, making sure we have the same version everywhere.
