-### 2023-03-08: RNS β 0.5.1
+### 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**
