I think it is time to prepare the 3.2 manual as soon as you have time.
I hope you still have the script you used for 3.1. If I remember
correct you did the following, which should now be done for 3.2:
1/list all manual pages in all languages for 3.1
3/change all links from 3.1 to 3.2, change all page names from 3.1 to 3.2
4/upload the new pages
5/lock the 3.1 manual so it is only editable by admins. All new edits
should go to the 3.2 manual.
