+## Supported Versions
+
+|          Version         | Supported          |
+| ------------------------ | ------------------ |
+| HEAD of master           | :white_check_mark: |
+| Latest released revision | :white_check_mark: |
+| All old revisions        | :x:                |
+
+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](https://github.com/jesec/flood/issues) 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. 
+

+
+Suggestions for general security enhancements and/or mitigations shall be reported to [issue tracker](https://github.com/jesec/flood/issues).

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