Please test the 2.113 release candidate. It contains features 
from up to March 2026, since it was tagged then, but the release 
stalled afterwards. I asked Razvan (our project manager) for a 
status update throughout July, but he wanted to prioritize 
getting a release done ASAP, so here it is. Expect more details 
from him soon.

Also, expect a 2.114 beta soon with all the latest features! Note 
that with the new release workflow on GitHub, 2.113 can still get 
point releases even after 2.114 is released. So if the jump from 
2.112 to 2.114 is too big, you can stick with 2.113 for a while.

The current schedule is:

But as always, feedback is welcome.
