all the releases are releases, with new features and whole new versions of stuff they contain. These get maintained, security patches and other fixes get made to the releases for the support period of that release, there is no service pack or patch tuesday type process, fixes get released when ready.
https://wiki.ubuntu.com/Releases The LTS releases tend to aim for long term supportability, with ends up being a bit contradictory, sometimes using not the cutting edge version of certain components because they might have to be changed a lot, sometimes deliberately going for something that is only just ready so not to have to support an obsolete architecture of something for a long time.
