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.
