Question is if we should upgrade to 4.x or wait for 5.x

The PyLucene project has gone dormant for lack of interest: it can no longer
garner the votes, needed from the Lucene PMC, and appreciated from users, to
authorize a release via the Apache Foundation. The 4.10.4 release has been
languishing in release limbo since March 10, 2015.

Doing a port to 5.x is certainly possible but requires some work, especially
in porting (some) unit tests from Java to Python. General lack of interest is
not a motivating factor. As of now, the way to revive the project would be to
vote for releases when they're announced (Lucene PMC _and_ users) and send in
patches towards a 5.x port.
It would also be a useful move to enable JCC to support Python 3.

I'd be happy to get the projects (PyLucene and JCC) going again but not into a

Thank you for your interest in PyLucene all these years (over 10 years now) !
