3.27 (not yet released)
=======================

New features
------------

* Tests can now be run concurrently across multiple processes. You can use
  `pytest-xdist`_ for that. For tests using `PostgresApptestConfiguration` you
  should be aware that `startpgcluster()` can't run concurrently. Workaround is
  to call pytest with ``--dist=loadfile`` to use a single test process per test
  module or use an existing database cluster and set ``db-host`` and
  ``db-port`` of ``devtools.DEFAULT_PSQL_SOURCES['system']`` accordingly.
