Well seems as if the DotNetNuke core team has given all us DNN developers a late Christmas present. Seems on Boxing day we had a new maintenance release which can be found at the DNN Downloads.
As with all releases it bears reminding to always do a backup of your current installation if you are going to do an upgrade. For best results it is better to do a backup and then restore it to a test environment if you have the abilities and then perform your upgrade and do some testing. If all the tests go well then do your upgrade to your production environment.
Also to take note of with this release is that if you are using the Active Directory provider and looking to upgrade then please take a look at this post on the DotNetNuke forum found here.

For anyone looking to build a new site build on DNN. I would install this new version and do some testing to see if anything shakes out that would cause concern for further development.
