Just an update for any other sites using the Open University's Moodle 2 modules that I am responsible for, such as ForumNG, OU blog, OU wiki, and subpage.
Currently these modules are available and maintained for Moodle 2.2, with stable versions updated monthly (and occasionally at other times) when there are changes. In order to get the updates, you have to grab them from our GitHub site as I do not have time to do the manual update process for the Moodle plugin site.
Moodle 2.3 is about to be released but the OU will not be using it immediately. There are changes in Moodle 2.3 which break some of our modules, especially ForumNG. If you rely on our modules and don't want to do without them, it would be advisable not to upgrade to 2.3 until we do.
I don't promise dates and these might change but I would expect that we will have 2.3-compatible but untested versions of these modules in our code repositories at some point during September. It looks likely that our first 2.3 stable branch will be in early December.
Before then, if people wish to submit patches (using our GitHub site) to fix problems so that the modules do actually work in 2.3 earlier, you could do and if it seems safe I will include it. But please test the patch fully against 2.2 before submitting.
