stable branches update

[Bruno Haible]

I updated the branches stable-202301 and stable-202307 with the bug fixes
up to 2023-12-31.

Also, I created a new stable branch stable-202401.

The branch stable-202301 being one year old, it will no longer be updated.
Users of this branch are recommended to switch to stable-202307.
