 LibreOffice 4.4.x series stable backports ppa (and SRU-testing for vivid)
http://sweetshark.livejournal.com/10977.html

This ppa will:
- not contain alpha and beta releases like 4.4.0~beta2
- not contain updates to the next major (4.5.x)
- contain minor release updates and their release candidates -- these can be
  considered stable

Note that for minor release updates (4.4.1, 4.4.2, 4.4.3 ...) an rc2 is almost always exactly the same as the final version.

See: https://wiki.documentfoundation.org/ReleasePlan for details,
and: http://www.libreoffice.org/discover/new-features/ and https://wiki.documentfoundation.org/ReleaseNotes/4.4 for new features and fixes.
