AlwaysOn Read-Intent Support
SharePoint 2013 SP1 + Apr 2014 CU support Read-Only instances with AlwaysOn Availability Groups, but SharePoint does not implement Read-Intent, allowing the read routing functionality native to AGs. Read-Intent would allow administrators to make use of the secondary node in the AG for read-only queries, thereby potentially increasing performance of the farm.

This will be pretty cool if Microsoft will implement this!
