+```
+
+### 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**

+### 2023-10-31: RNS β 0.6.3
+
+This release brings a series of under-the-hood reliability improvements and bugfixes. But most notably, Reticulum can now establish links over even ultra low bandwidth mediums, all the way down to 5 bits per second.
+
+Thanks to @jschulthess, who contributed to this release!
+
+**Changes**
+- Implemented link establishment on ultra low bandwidth links
+- Added link quality calculations to RNode interfaces
+- Added physical layer link stats to Link and Packet classes
+- Added userspace service documentation to the manual
+- Improved path rediscovery in quickly changing topographies
+- Improved shared interface reconnection on service restart
+- Improved exception handling on interface detachment
+- Updated formatted print functions
+
+**Bugfixes**
+- Fixed a missing USB command definition in the RNode interface driver
+- Fixed a bug in link error handling that could cause an interface to detach
+
+**Release Hashes**

 Welcome, and thank you for your interest in contributing to Reticulum!

-Apart from writing code, there are many ways in which you can contribute. Before getting started, please read these guidelines.
+Apart from writing code, there are many ways in which you can contribute. Before interacting with this community, read these short and simple guidelines.
+
+## Expected Conduct
+
+First and foremost, there is one simple requirement for taking part in this community: While we primarily interact virtually, your actions matter and have real consequences. Therefore: **Act like a responsible, civilized person** - also in the face of disputes and heated disagreements. Speak your mind here, discussions are welcome. Just do so in the spirit of being face-to-face with everyone else. Thank you.

 ## Asking Questions

-If you want to ask a question, do not open an issue.
+If you want to ask a question, **do not open an issue**. The issue tracker is used by people *working on Reticulum* to track bugs, issues and improvements.

-Instead, ask away on the [discussions](https://github.com/markqvist/Reticulum/discussions) or on the [Reticulum Matrix channel](https://unsigned.io/contact.html#reticulum:matrix.org) at `#reticulum:matrix.org`

+## Providing Feedback & Ideas

-Likewise, feedback, ideas and feature requests are a very welcome way to contribute, and should also be posted on the [discussions](https://github.com/markqvist/Reticulum/discussions), or on the [Reticulum Matrix channel](https://unsigned.io/contact.html#reticulum:matrix.org) at `#reticulum:matrix.org`

+
+Please do not post feature requests or general ideas on the issue tracker, or in direct messages to the primary developers. You are much more likely to get a response and start a constructive discussion by posting your ideas in the public channels created for these purposes.

 ## Reporting Issues

-If you have found a bug or issue in Reticulum, please report it on the [issue tracker](https://github.com/markqvist/Reticulum/issues).
+If you have found a bug or issue in this project, please report it using the [issue tracker](https://github.com/markqvist/Reticulum/issues). If at all possible, be sure to include details on how to reproduce the bug.
+
+Anything submitted to the issue tracker that does not follow these guidelines will be closed and removed without comments or explanation.

 ## Writing Code

-If you are interested in contributing code, fixing open issues or adding features, please coordinate the effort with the maintainer or one of the main developers first, to ensure your efforts are in alignment with the [Roadmap](./Roadmap.md) and current development focus.
+If you are interested in contributing code, fixing open issues or adding features, please coordinate the effort with the maintainer or one of the main developers **before** submitting a pull request. Before deciding to contribute, it is also a good idea to ensure your efforts are in alignment with the [Roadmap](./Roadmap.md) and current development focus.
+
+Pull requests have a high chance of being accepted if they are:
+
+- In alignment with the [Roadmap](./Roadmap.md) or solve an open issue or feature request
+- Sufficiently tested to work with all API functions, and pass the standard test suite
+- Functionally and conceptually complete and well-designed
+- Not simply formatting or code style changes
+- Well-documented
+
+Even new ideas and proposals that have not been approved by a maintainer, or fall outside the established roadmap, are *occasionally* accepted - if they possess the remaining of the above qualities. If not, they will be closed and removed without comments or explanation.

+Remote Management
+-----------------
+
+It is possible to allow remote management of Reticulum
+systems using the various built-in utilities, such as
+``rnstatus`` and ``rnpath``. To do so, you will need to set
+the ``enable_remote_management`` directive in the ``[reticulum]``
+section of the configuration file. You will also need to specify
+one or more Reticulum Identity hashes for authenticating the
+queries from client programs. For this purpose, you can use
+existing identity files, or generate new ones with the rnid utility.
+
+The following is a truncated example of enabling remote management
+in the Reticulum configuration file:

 The ``TCPServerInterface`` allows users to host an instance accessible over TCP/IP. This
 method is generally faster, lower latency, and more energy efficient than using ``I2PInterface``,
 however it also leaks more data about the server host.

 inspecting your packets may be able to record packet metadata like time of transmission and packet size.
 Even though Reticulum encrypts traffic, TCP does not, so an adversary may be able to use
 packet inspection to learn that a system is running Reticulum, and what other IP addresses connect to it.
 Hosting a publicly reachable instance over TCP also requires a publicly reachable IP address,
 which most Internet connections don't offer anymore.
