Something I noticed while watching colleval.log today was that by updating All Systems, every collection limited to All Systems also immediately updated. So no longer do we need to update All Systems, then update the collection we might be after, instead it happens automatically. I confirmed with a few other MVP’s that is the behavior for 2012, although I’m sure not necessarily widely known. This will apply to all collections that are limited, not just the All Systems limited collections. This could be interesting in very large environments with hundreds of collections.
Hope you find this information useful.
