The UHU5 upgrades to Regions & Places are coming along nicely, which should put off any further refactoring until PHP 5.3 is released (late static binding FTW!). The Region & Places upgrades are of course holding up the Events upgrade, since an Event object will have a Parcel sub-object (I’m sure I’ll have fun working around the issue of old events being held long-nuked regions/parcels).
Once these upgrades have been finished, I’ll continuing work on the SLOpenID upgrade (preliminary testing on a replacement server has been completed).
