+**For Minecraft: Bedrock Edition 1.17.0**
+
+### 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.
+
+# 3.20.0
+- Added support for Minecraft: Bedrock Edition 1.17.0
+- Removed compatibility with earlier versions.
