+### 2024-09-09: RNS β 0.7.7
+
+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!
+
+**Changes**
+- Added key ratchet rotation and signalling
+- Added ratchet API to documentation
+- Added initial support for flashing T-Echo devices to `rnodeconf`
+- Added remote management config options to example config
+- Added automtic integration tests to source repository
+- Fixed a regression that caused RNS not to work on Python versions lower than 3.10
+- Fixed missing `establishment_rate` property init on Link objects
+
+**Release Hashes**

 For each release cycle of Reticulum, improvements and additions from the five [Primary Efforts](#primary-efforts) are selected as active work areas, and can be expected to be included in the upcoming releases within that cycle. While not entirely set in stone for each release cycle, they serve as a pointer of what to expect in the near future.
 
 - The current `0.7.x` release cycle aims at completing
+  - [x] Automatic asynchronous key ratcheting for non-link traffic
+  - [ ] API improvements based on real-world usage and feedback
+  - [ ] Expanded hardware support
   - [ ] Overhauling and updating the documentation
   - [ ] Distributed Destination Naming System
   - [ ] Create a standalone RNS Daemon app for Android
