Hi Saikat!
I'd love to see this merged. I can do a bit of testing if necessary.
Sorry for my ignorance but I couldn't find answers to these questions
easily in the PR or on Jira:
How is this configured? Is it always on when compiled in? Can the
parameters (e.g. cache size, maximum TTL) be configured? Is the cache
stored in RAM, on disk, or is that selectable?
From my perspective, I'd like to have a cache with a tunable size (say
1GB of RAM, preferably in some memory-efficient/compressed form), a LRU
invalidation policy, and a very long TTL (say 1 week or more) unless the
underlying data changes and thus the cache has to be invalidated, which
should happen immediately.
We currently use Varnish for this sort of caching but this feature could
eliminate that dependency, at least for simple setups.

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.
