Highlights

Revert of Default TTL Behavior Change

In the previous release, the default TTL behavior was modified but a backwards compatibility issue was discovered. This version changes it back to the original behavior of deleting the data from both Alluxio and the underlying storage as opposed to only deleting the data from Alluxio. See more details in the corresponding github PR.
