- Adds support down to SQL Server 2012
- The adapter is now automatically tested with Fishtowns official adapter-tests to increase stability when making
changes and upgrades to the adapter.

Fixes:

- Fix for lack of precision in the snapshot check strategy. Previously when executing two check snapshots the same

NOTE: This fix will create a new snapshot version in the target table
on first run after upgrade.
