+# 4.26.0
+Released 6th December 2023.
+
+**For Minecraft: Bedrock Edition 1.20.50**
+
+This is a support release for Minecraft: Bedrock Edition 1.20.50.
+
+**Plugin compatibility:** Plugins for previous 4.x versions will run unchanged on this release, unless they use internal APIs, reflection, or packages like the `pocketmine\network\mcpe` namespace.
+Do not update plugin minimum API versions unless you need new features added in this release.
+
+**WARNING: If your plugin uses the `pocketmine\network\mcpe` namespace, you're not shielded by API change constraints.**
+Consider using the `mcpe-protocol` directive in `plugin.yml` as a constraint if you're using packets directly.
+
+## General
+- Added support for Minecraft: Bedrock Edition 1.20.50.
+- Removed support for older versions.
