Gustaf,
Thanks for all your work on this. It looks great. I've just upgraded to 5.2.3 and xowiki 0.36 encountering 2 issues - both are now sorted, but just for reference.
1. Had to update xotcl to 1.4.0 (from 1.3.6) after experiencing the xowiki::Package error - I should have started with this one!!
2. There is a missing dependency to acs-datetime for the mini-calendar display - dt_systime is not found without this package.
Thanks again
Matthew
