+**For Minecraft: Bedrock Edition 1.14.0**
+
+### 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.
+
+# 3.11.0
+- Added support for Minecraft: Bedrock Edition 1.14.0
+- Removed compatibility with 1.13.0
+
+# 3.11.1
+- Fixed blocks with incorrect properties when placed or interacted with.
