Flood does NOT provide LTS support. Older revisions are deprecated as soon as a newer revision is released.

Generally only the latest revision (HEAD of master) is supported. However, issue tracker is still open to reports from users of the Latest released revision. In rare circumstances, if there is a vulnerability that requires urgent attention, and, if the HEAD of master is occupied with changes which maintainers are not comfortable to release, relevant changes may be backported to the Latest released revision to release a patch revision.

You are advised to upgrade to the latest release as soon as possible.

If you discover a security vulnerability within Flood, please send an e-mail to maintainer.

Suggestions for general security enhancements and/or mitigations shall be reported to issue tracker.

If you are unsure about the severity, send an email first.
