To folks who have the "Mocca Calendar"[1] application installed in their XWiki instances: I have just released a new version 2.2.1 to which you might want to update to, as it contains quite a few bugfixes and improvements, thanks to patches send in by several contributors.[2] However the new release does not show up when you try to update via the "Extension Updater" in your wiki admin; instead the latest version found there will be 2.1.9. This happened due to a glitch when reorganizing the code which changed the Extension-Id for that application. Instead please go to "Add extensions", search for "Mocca Calendar" and when the search result comes up, the extension manager should propose you to update to the correct version 2.2.1 Also while upgrading at least in my test instances I got a few spurious conflicts. If you get them too, even while you have made no modifications to the "code" part of the calendar, please choose to keep the new version to get all updates installed property. Best regards and sorry for the hiccup, Clemens [1] http://extensions.xwiki.org/xwiki/bin/view/Extension/MoccaCalendar [2] http://jira.xwiki.org/browse/MOCCACAL-32?filter=13491
