Freeradius cassandra driver not available in latest stable version

Question

I would like to make my Freeradius environment to store data in a Cassandra DB, but when looking to the repository https://github.com/FreeRADIUS/freeradius-server, the following branches don't have this driver:

• release_3_0_25 (STABLE)
• release_3_2_0 (LATEST STABLE)
• branch_4_0_0 (NOT STABLE)

The branches that have this driver but are NOT STABLE:

• master
• python-v4-rework

The last time the cassandra driver was worked on was 3 years ago according to what I see on both of the above branches but it was never actually released, so I don't think that is a good sign.

So, I would like to know if the Freeradius developers intend to eventually release a stable version with the Cassandra driver or not and when it is estimated for this release to happen? I couldn't find this information anywhere.
