+### Note about API versions
+Plugins which don't touch the protocol and compatible with any previous 3.x.y version will also run on these releases and do not need API bumps.
+Plugin developers should **only** update their required API to this version if you need the changes in this build.
+
+**WARNING: If your plugin uses the protocol, you're not shielded by API change constraints.** You should consider using the `mcpe-protocol` directive in `plugin.yml` as a constraint if you do.

+- Removed compatibility with earlier versions.
+
+# 3.26.1
+- Fixed a bug in chunk sending that caused double chests to not be paired, signs to be blank, and various other issues.
+
+# 3.26.2
+- Improved error messages shown by `start.cmd`, `start.sh` and `start.ps1` when the PHP binary was not found.
+- The value of PHPRC is now shown when erroring out due to unsatisfied PHP requirements.
+- Removed restriction on the range of valid channels for `auto-updater.channel` in `pocketmine.yml`.
+
+# 3.26.3
+- `PlayerExperienceChangeEvent->setNewProgress()` now performs range checks. This fixes the root of a very old and confusing crash bug which took several years to identify the cause of.
+  - Note that the defective plugin(s) which caused this problem will still cause a server crash, but the plugin responsible will now get blamed correctly.

+- Fixed skins appearing black when using RTX resource packs.
+- Fixed chunks containing furnaces in old worlds (pre-2017) being discarded as corrupted.
+  - This was caused by a strict corruption check detecting bad data created by a bug in PocketMine-MP that was fixed in 2017.
