+### 2023-05-12: RNS β 0.5.2
+
+This maintenance release brings a number of bugfixes and improvements.
+
+**Important!** This release breaks backwards compatibility with `Channel` and `Buffer` for all previous releases, due to the addition of compression and windowing.
+
+**Changes**
+- Added ability to trust external signing keys to `rnodeconf`
+- Added basic windowing to `Channel` and `Buffer`, improving performance over faster links
+- Added per-packet compression to `Channel`
+- Added automatic multi-interface duplicate deque to AutoInterface
+- Fixed received link packet proofs not resetting link watchdog stale timer
+- Fixed a missing exception isolation of packet delivery callbacks
+- Fixed resent packets not getting repacked
+
+**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 `0.5.x` release cycle aims at completing
+  - [x] Reach feature-completion of the Reticulum API
+  - [x] Improve performance and efficiency of the `Buffer` and `Channel` API
   - [ ] Overhauling and updating the documentation
   - [ ] Performance and memory optimisations of the Python reference implementation
   - [ ] Fixing potential bugs
   - [ ] Add automatic retries to all use cases of the `Request` API
-  - [ ] Improve performance and efficiency of the `Buffer` and `Channel` API
 
 ## Primary Efforts
 The development path for Reticulum is currently laid out in five distinct areas: *Comprehensibility*, *Universality*, *Functionality*, *Usability & Utility* and *Interfaceability*. Conceptualising the development of Reticulum into these areas serves to advance the implementation and work towards the Foundational Goals & Values of Reticulum.

+Resolving Dependency & Installation Issues
+=============================================
+On some platforms, there may not be binary packages available for all dependencies, and
+``pip`` installation may fail with an error message. In these cases, the issue can usually
+be resolved by installing the development essentials packages for your platform:
+
+.. code::

+
+    # Arch / Manjaro / Derivatives
+    sudo pamac install base-devel
+
+    # Fedora
+    sudo dnf groupinstall "Development Tools" "Development Libraries"
+
+With the base development packages installed, ``pip`` should be able to compile any missing
+dependencies from source, and complete installation even on platforms that don't have pre-
+compiled packages available.

+Resolving Dependency & Installation Issues
+=============================================
+On some platforms, there may not be binary packages available for all dependencies, and
+``pip`` installation may fail with an error message. In these cases, the issue can usually
+be resolved by installing the development essentials packages for your platform:
+
+.. code::
+
+    # Debian / Ubuntu / Derivatives
+    sudo apt install build-essential
+
+    # Arch / Manjaro / Derivatives
+    sudo pamac install base-devel
+
+    # Fedora
+    sudo dnf groupinstall "Development Tools" "Development Libraries"
+
+With the base development packages installed, ``pip`` should be able to compile any missing
+dependencies from source, and complete installation even on platforms that don't have pre-
+compiled packages available.

-Reticulum on ARM64
+Platform-Specific Install Notes
 ==============================================
-On some architectures, including ARM64, not all dependencies have precompiled
-binaries. On such systems, you may need to install ``python3-dev`` before
-installing Reticulum or programs that depend on Reticulum.
 
-.. code::
+Some platforms require a slightly different installation procedure, or have
+various quirks that are worth being aware of. These are listed here.
 
-   # Install Python and development packages
-   sudo apt update

-Reticulum on 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.

-Reticulum on Android
-==============================================
+Android
+^^^^^^^^^^^^^^^^^^^^^^^^
 Reticulum can be used on Android in different ways. The easiest way to get
 started is using an app like `Sideband <https://unsigned.io/sideband>`_.
