The issue comes then to what is needed to make a stable release?

Some question to developers:
1. Or asking in another way what is the current state of 2.5?
2. What do we need to do to enter the freeze stage?
3. What are your plans for features that you

The purpose of the above question is have an idea about the current state of the
development.

2.4.0 was released in May of 2024, the first release candidate was released in
January. In terms of testing it is easier if the releases are smaller than
larger.

I am in no hurry to have 2.5 released but on the other hand I would like to
avoid having it slip for several years.
