No attempt +has been made to preserve backwards-compatibility: + +* Attempting to restore old pickles will give ``OLM_CORRUPTED_PICKLE``. +* Attempting to send session_keys between old and new versions will give + ``OLM_BAD_SESSION_KEY``. +* Attempting to send messages between old and new versions will give one of a + number of errors. + +There were also a number of implementation changes made as part of this +release, aimed at making the codebase more consistent, and to help with the +implementation of the group message signatures. + + Changes in `1.1.0 <http://matrix.org/git/olm/commit/?h=1.1.0>`_ =============================================================== |
