Package: gajim-omemo Version: 1.0.0-1 Severity: grave Set to grave, because "makes the package in question unusable by most ... users".
As outcome of a security audit of the OMEMO protocol (XMPP e2e encryption method), it has been changed: The auth tag is no longer appended to the payload, but now to the key. Because all clients now change to the new scheme, gajim-omemo needs to change, too. Upstream is updated already.
