Django Evolution 0.7.3

Release date: July 24, 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.
