IdExtenso version 2.31008 (Oct. 8, 2023) has just been released on GitHub. It contains some essential additions and fixes in the core branch, but above all an impressive number of new etc modules that I could not summarize here.

The best is therefore to go to the CHANGELOG page which gives you a complete inventory of all the progress made in recent months.
