Considering the project is in the heavy WIP stage, only the latest released version will receive support.

If you found or think you have found a vulnerability/security flaw in the software, email me directly at mathieu@viales.fr You can expect a response within one or two days.

If you want to report a "normal" bug, that is a bug not related to security, or request a new feature, create an issue in the issue tracker. You should get a response within 2 days.
