-This release add support for RNodes with multiple radio transceivers, courtesy of @jacobeva. It also brings a number of functionality and performance improvements, and fixes several bugs.
+This release adds support for automatic encryption key ratcheting for all packets, not just those sent over Reticulum links. In practical terms, this adds forward secrecy to packets sent with the raw `Packet` API.
+
+In this release, the ratchets feature must be enabled on a per-destination basis by calling the `enable_ratchets` method on the relevant destination. In a future release, ratchets may become the default option, but for backwards-compatibility, it is currently optional. For more information, read the API documentation.
+
+**Please note!** Versions of RNS prior to `0.7.7` will not be able to pass announces for destinations with ratchets enabled! If you use applications that can use ratchets (for example, LXMF version `0.5.0` and up), it is important that you update all transport instances on your network to `0.7.7`.
+
+Thanks to @deavmi, @faragher, @jacobeva, @jeremy and @jeremybox for contributing to this release!
