I'd like to go ahead with 3.1.0.
The work on a query cache for Fuseki [*] was tested by Osma and found to
be useful. There was also feedback on configuration and bounding the
resources consumed by the caches. Without the ability to configure it
(including turn it off) I don't think that putting it in right before a
release is a good idea. There are is still some discussion to be had
about the detailed design goals.
So what I suggest is release Jena 3.1.0 now as-is, and start a
testing/evaluation phase for a configurable cache.
As a cache is most important under load, and Fuseki is used in deployed
and public facing systems, I'm concerned that we block people picking up
all the other things in 3.1.0. I think it would be good to get wider
testing via users@. That will take time. (And then if people don't test
it until after its in a release ... well, we can only do our best.)

Hi Andy!
I'm happy with the current state of Jena and would support a release.
This time I've been more diligent in using recent snapshots so there
should be less chance of problems that surface only around release time.
I have no outstanding work that I want to do for jena-text currently.
JENA-1134/AnalyzingQueryParser (which you can consider including in the
release notes) was the major item for me since the previous release,
plus some bugfixes that were done earlier.

Version 3.1.0 has quite a few good things in it1
I think it is about time we released it.
So this is a first ping for anything you want to get done for it.
As for timing - I can RM it sometime in the next few weeks though it
will have to fit around other things.
