Eurion 1.6.4

Fixed

Updates stopped by the certificates. After Traefik had obtained or renewed a certificate, the service that copies the certificates to the mail server could crash over and over again. The next update then failed and was rolled back. The service now handles Traefik's new file format, and a failed attempt is retried after one minute instead of stopping the update.
SAML responses from real providers. Identity providers send the SAML response as a form post, and it was rejected. It is now accepted. SAML is still not supported for use, see SAML 2.0.

Installed as usual from System Updates in the admin portal. No change to the configuration is needed.
