======================
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``.
