No secret I prefer the pace of LibreOffice development, but Apache OpenOffice is not dead, just glacial.

Developers and QA participants have drifted away but still a solid offering.

In fact Apache OpenOffice project is wrapping up builds of the 4.1.4 branch with Release Candidate 2 (rc2) just posted:

The 4.1.3 build was released October 12, 2016 and is available here:
