=== ADDITIONS ===

- Added the possibility to add for each post to a remailer of the
headers.

- The PGP backend "back-gpg" now uses a unique keyring and no longer
pollutes the user's keyring.

- The path to the config can now be set via the CLI.

=== CHANGES ===

- License change : Switching from GPLv3 to CeCILL v2.1. No major change
since the CeCILL license is fully compatible with the GPL licenses.

- Change of the Github Actions setup, artifactes will only be built on
Linux (Windows failed because not supported by
softprops/action-gh-release).

- Disabling some remailers (because they don't respond to MX requests).
