Supported Versions

Unless explicitly stated otherwise, we only support the latest released version (and the current development version) of firejail, which should be the one in the following page:

Versions older than the latest usually have outdated profiles and may contain bugs and security vulnerabilities that were already fixed in a later version.

See Installing for distribution-specific instructions and recommendations.

If the firejail version in your distribution is older than the latest released version (and at least a few days have passed since the release), please contact the maintainers for your distribution and request an update to the relevant package(s).

In the meantime, you can build and install the current development version.

See also CONTRIBUTING.md.

Released versions are listed in the table below, which is mostly intended for historical reference and may be outdated and/or incomplete.
