Question: state of 3.0 / 3.1 branches

Background:
We are using mimalloc 2 for some time under Windows, and it works great, except for a problem with large memory allocations after version 2.1.7. This may have been by design, and is not the issue here - but the problem is gone in the dev3 branch, so we want to switch to version 3 ASAP.

Question:
There are the 3.0 and 3.1 branches, both are actively developed, and the release notes indicate that 3.1.5 is still beta, while there are no release notes for 3.0.10 (the last ones are for 3.0.3, which also stated it as beta). The question is: is the 3.0 branch the stable (or LTS) branch? What is it's state, it is still considered beta? What is the difference between the 3.0 and 3.1 releases, and which one is better suited for production?

Thanks!

(creating a question issue, as there are no discussions available)

Start by comparing the 3.0 and 3.1 branches, their release notes, and the dev3 branch referenced in the issue. The work is done when the branch stability, beta status, release differences, and production recommendation are clearly documented or answered.
