Monal 4.3 is going to be a huge update the iOS and Mac UI. It is feature complete and has been in testing for a few weeks. I expect to release it next week. When it comes out though, I will have switched to Apple’s GCM library this will also allow me to release in France. The change in libraries will prevent OMEMO from working with some other clients. Clients that send with a 16 byte iv will not be able to send to Monal anymore. Client that can’t accept the 12 byte iv will not be able to accept message from Monal anymore.
