New in Previews this Week

Two early release previews received new updates this week.

Velocity is a highly scalable application cache that reduces the number of data lookups in a distributed system. Cache management is provided to make building caches into these types of applications easier. This week's update brings Velocity to a third release. A readme and documentation are available at the same location as the download.

MEF is an extensibility framework for building applications that use interchangeable components. This week's update brings MEF to a fifth release, with the amount of changes here smaller than in some of the previous ones. You can get a list of changes for the release in the release notes.
