New table_copy destination plugin. Useful when you just have to make a straight copy of one table from legacy to drupal and you would rather use migration framework instead of export/import. Migration also has handy highwater feature.

Allow individual migrations to have prepare methods. These are called last by MigrateDestinationEntity::prepare. Illustrate this feature in the BeerUser migration by converting a Denver ISO time to unix timestamp.

A different direction. This one starts fresh with migrate as a drush based application. Its only web component will be a read-only dashboard. All content sets and their fetching callbacks are defined in code. See migrate_example module as an example. Still lots of work to do. Don't bother running this yet.
