However, critical security vulnerabilities in dependencies or other unanticipated circumstances may arise which necessitate breaking compatibility earlier. + +We intend to continue producing .deb packages for Debian 9 (Stretch) and Ubuntu 16.04 (Xenial) through the transition period. + Synapse 1.25.0rc1 (2021-01-06) ============================== |
