+```
+
+### 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**

 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

 Hosting a publicly reachable instance over TCP also requires a publicly reachable IP address,

+
+MacOS
+^^^^^^^^^^^^^^^^^^^^^^^^^
+To install Reticulum on macOS, you will need to have Python and the ``pip`` package

+and if it is, which version is installed, and whether the ``pip`` package manager is
+also installed and set up. If in doubt, you can `download and install <https://www.python.org/downloads/>`_
+Python manually.

+
+.. code::
+
+   # Install Reticulum and utilities with pip:
+   pip3 install rns

+   cases lead to version conflicts, it does not generally pose any problems, especially
+   not in the case of installing Reticulum.
+
+Additionally, some version combinations of macOS and Python require you to
+manually add your installed ``pip`` packages directory to your `PATH` environment
+variable, before you can use installed commands in your terminal. Usually, adding
+the following line to your shell init script (for example ``~/.zshrc``) will be enough:

+   and `reticulum-openwrt <https://github.com/gretel/reticulum-openwrt>`_
+   repositories for more information.
+

+
+.. code::
+
+   # Install dependencies
+   opkg install python3 python3-pip python3-cryptography python3-pyserial
+   
+   # Install Reticulum

+   It is likely that other versions may require slightly altered installation
+   commands or package names. You will also need enough free space in your
+   overlay FS, and enough free RAM to actually run Reticulum and any related
+   programs and utilities.
+
+Depending on your device configuration, you may need to adjust firewall rules
+for Reticulum connectivity to and from your device to work. Until proper
+packaging is ready, you will also need to manually create a service or startup
+script to automatically laucnh Reticulum at boot time.
+
+Please also note that the `AutoInterface` requires link-local IPv6 addresses
+to be enabled for any Ethernet and WiFi devices you intend to use. If ``ip a``
+shows an address starting with ``fe80::`` for the device in question,
+``AutoInterface`` should work for that device.
+
+Raspberry Pi
+^^^^^^^^^^^^^^^^^^^^^^^^^
+It is currently recommended to use a 64-bit version of the Raspberry Pi OS
+if you want to run Reticulum on Raspberry Pi computers, since 32-bit versions
+don't always have packages available for some dependencies. If Python and the
+`pip` package manager is not already installed, do that first, and then
+install Reticulum using `pip`.
+
+.. code::
+
+   # Install dependencies
+   sudo apt install python3 python3-pip python3-cryptography python3-pyserial
+   
+   # Install Reticulum
+   pip install rns --break-system-packages
+
+.. note::
+   The ``--break-system-packages`` directive is a somewhat misleading choice
+   of words. Setting it will of course not break any system packages, but will simply
+   allow installing ``pip`` packages user- and system-wide. While this *could* in rare
+   cases lead to version conflicts, it does not generally pose any problems, especially
+   not in the case of installing Reticulum.
+
+While it is possible to install and run Reticulum on 32-bit Rasperry Pi OSes,
+it will require manually configuring and installing required build dependencies,
+and is not detailed in this manual.
+
+
+RISC-V
+^^^^^^^^^^^^^^^^^^^^^^^^
+On some architectures, including RISC-V, not all dependencies have precompiled
+binaries. On such systems, you may need to install ``python3-dev`` (or similar) before
+installing Reticulum or programs that depend on Reticulum.
+
+.. code::
+
+   # Install Python and development packages
+   sudo apt update
+   sudo apt install python3 python3-pip python3-dev
+
+   # Install Reticulum
+   python3 -m pip install rns
+
+With these packages installed, ``pip`` will be able to build any missing dependencies
+on your system locally.

+Windows
+^^^^^^^^^^^^^^^^^^^^^^^^^
+On Windows operating systems, the easiest way to install Reticulum is by using the
+``pip`` package manager from the command line (either the command prompt or Windows
+Powershell).
+
+If you don't already have Python installed, `download and install Python <https://www.python.org/downloads/>`_.
+At the time of publication of this manual, the recommended version is `Python 3.12.7 <https://www.python.org/downloads/release/python-3127>`_.
+
+**Important!** When asked by the installer, make sure to add the Python program to
+your PATH environment variables. If you don't do this, you will not be able to
+use the ``pip`` installer, or run the included Reticulum utility programs (such as
+``rnsd`` and ``rnstatus``) from the command line.
+
+After installing Python, open the command prompt or Windows Powershell, and type:
+
+.. code::
+
+   pip install rns
+
+You can now use Reticulum and all included utility programs directly from your
+preferred command line interface.

+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:

+
+
+MacOS
+^^^^^^^^^^^^^^^^^^^^^^^^^
+To install Reticulum on macOS, you will need to have Python and the ``pip`` package
+manager installed.
+
+Systems running macOS can vary quite widely in whether or not Python is pre-installed,
+and if it is, which version is installed, and whether the ``pip`` package manager is
+also installed and set up. If in doubt, you can `download and install <https://www.python.org/downloads/>`_
+Python manually.
+
+When Python and ``pip`` is available on your system, simply open a terminal window
+and use one of the following commands:
+
+.. code::
+
+   # Install Reticulum and utilities with pip:
+   pip3 install rns
+   
+   # On some versions, you may need to use the
+   # flag --break-system-packages to install:
+   pip3 install rns --break-system-packages
+
+.. note::
+   The ``--break-system-packages`` directive is a somewhat misleading choice
+   of words. Setting it will of course not break any system packages, but will simply
+   allow installing ``pip`` packages user- and system-wide. While this *could* in rare
+   cases lead to version conflicts, it does not generally pose any problems, especially
+   not in the case of installing Reticulum.
+
+Additionally, some version combinations of macOS and Python require you to
+manually add your installed ``pip`` packages directory to your `PATH` environment
+variable, before you can use installed commands in your terminal. Usually, adding
+the following line to your shell init script (for example ``~/.zshrc``) will be enough:
+
+.. code::
+
+   export PATH=$PATH:~/Library/Python/3.9/bin
+
+Adjust Python version and shell init script location according to your system.

+
+OpenWRT
+^^^^^^^^^^^^^^^^^^^^^^^^^
+On OpenWRT systems with sufficient storage and memory, you can install
+Reticulum and related utilities using the `opkg` package manager and `pip`.
+
+.. note::
+
+   At the time of releasing this manual, work is underway to create pre-built
+   Reticulum packages for OpenWRT, with full configuration, service
+   and ``uci`` integration. Please see the `feed-reticulum <https://github.com/gretel/feed-reticulum>`_
+   and `reticulum-openwrt <https://github.com/gretel/reticulum-openwrt>`_
+   repositories for more information.
+
+To install Reticulum on OpenWRT, first log into a command line session, and
+then use the following instructions:
+
+.. code::
+
+   # Install dependencies
+   opkg install python3 python3-pip python3-cryptography python3-pyserial
+   
+   # Install Reticulum
+   pip install rns
+
+   # Start rnsd with debug logging enabled
+   rnsd -vvv
+
+.. note::
+   
+   The above instructions have been verified and tested on OpenWRT 21.02 only.
+   It is likely that other versions may require slightly altered installation
+   commands or package names. You will also need enough free space in your
+   overlay FS, and enough free RAM to actually run Reticulum and any related
+   programs and utilities.
+
+Depending on your device configuration, you may need to adjust firewall rules
+for Reticulum connectivity to and from your device to work. Until proper
+packaging is ready, you will also need to manually create a service or startup
+script to automatically laucnh Reticulum at boot time.
+
+Please also note that the `AutoInterface` requires link-local IPv6 addresses
+to be enabled for any Ethernet and WiFi devices you intend to use. If ``ip a``
+shows an address starting with ``fe80::`` for the device in question,
+``AutoInterface`` should work for that device.
