   * Run explain plans on parameterized slow queries in AR4
 
   In our ActiveRecord 4 instrumentation, we moved to tracing slow queries
-  using the payloads from subscribing to ActiveSupport::Notifications for
-  `sql.active_record` events. As a result, we were unable to run explain
-  plans on parameterized queries. This has now been updated to pass along
-  and use the parameter values, when available, to get the explain plans.

   * Fix getMore metric grouping issue in Mongo 2.2.x instrumentation
 
-  A metric grouping issue had cropped up again when using the most recent
-  Mongo driver (2.2.0) with the most recent release of the database (3.2.4).
-  We now have a (hopefully) more futureproof setup for preventing these.

   * Padrino 0.13.1 Support
 
-  We have incorporated changes from the community that bring the agent up to
-  date with the new routing engine in Padrino 0.13.x. These changes address
-  how the agent generates a transaction name from a Padrino route. Users of
-  the latest versions of Padrino were previously seeing the default transaction
-  name "(unknown)" for all of their Padrino 0.13.x routes. With these changes,
-  users will instead see the full Padrino route template in their transaction
-  names, including any parameter placeholders. Thanks Robert Schulze for the
-  contribution!
