version 0.7.3 (24-July-2014):
	* Bug Fixes:
		* Fixed issues evolving unique_together attributes on models.

		  When adding unique_together constraints and then changing them within
		  a single evolve operation, any constraints listed more than once
		  would result in unnecessary duplicate SQL statements. These would
		  cause errors that would prevent the transaction from completing.

		* Adding and removing a unique_together constraint within an evolve
		  operation no longer breaks on PostgreSQL.

		* Errors importing a database backend on a modern Django no longer
		  results in unrelated errors about settings.DATABASE_ENGINE.
