Following the ARRv1 RTW release last month, the ARR team has released ARRv2 Beta1 release today. (The "official" announcement can be found here.)
ARRv2 is an incremental release that has all the features of ARRv1, but we added a support for disk cache. What is really exciting about this feature is that now we can start thinking about using ARR as a cache proxy. (Read about the disk cache feature here.) Also, we have added support for CARP (Cache Array Routing Protocol) and cache hierarchy management that will enable customers to build a network of ARR cache nodes in CDN (Content Delivery Network)/ECN (Edge Cache Network).
You can learn more about ARRv2 Beta 1 here.
