UAG SP3 is released and one of its main functions is the support for Windows 8 for accessing the UAG Portal or the UAG DirectAccess as well as supporting the new Exchange 2013 and SharePoint 2013 publish as well as other features.

There were couple of bugs with the UAG SP3 and they are addressed in the below 2 articles and how to fix them manually.

However Microsoft released later on the UAG SP3 Rollup 1, with this fix all mentioned bugs and more were fixed.

You must install the SP3 first then this Rollup 1.
