What's New in This Release: [ read full changelog ]
· IMPORTANT: Due to changes to multiparty key generation (in order to be compatible with the upcoming mobile apps), this version of Cryptocat cannot have multiparty conversations with previous versions. However private conversations still work.
· Fixed a bug found in the encryption libraries that could partially weaken the security of multiparty Cryptocat messages.
