I'm announcing the release of Postorius 1.0.3.

It contains an important security fix[1], so we strongly recommend that all sites running Mailman 3.0 in combination with Postorius update their instances to this version.

The easiest way to upgrade is via pip:

pip install --upgrade postorius

The latest tarball is also available on https://pypi.python.org/pypi/postorius.
