-## Unreleased
+## 0.5.0-alpha.0 / 28 Feb 2021
+
+This is an alpha release, but new servers should use this version rather than an older "stable" one.
 
 The `u-wave-http-api` package has been merged into `u-wave-core`. This package now contains both the library and the HTTP and WebSocket API for üWave servers.
 
+The minimum supported Node.js version is v12.20.0.
+
+`u-wave-core` now includes a basic CLI with some default configuration.
+
+```bash
+npm install --global u-wave-core@next
+u-wave-core --help
+```
