 **Health check timeout** is configured per-plugin via `HEALTH_TIMEOUT` (default: 5 seconds).
 
+## Protocol Versioning
+
+The plugin protocol uses explicit version negotiation to ensure forward compatibility. Both the server and plugin exchange their supported protocol version during `Initialize`:
+
+1. The server sends `protocol_version = 1` in `InitializeRequest`
+2. The plugin returns `protocol_version = 1` in `InitializeResponse`
+3. The server stores the plugin's version and checks it before calling any RPCs added in later versions
+
+**What this means for plugin developers:**
+
+- **You don't need to recompile** when the server adds new fields to existing messages. Protobuf handles this automatically — unknown fields are ignored, missing fields use zero-value defaults.
+- **You don't need to recompile** when the server adds new event types. Your plugin only receives events it subscribed to.
+- **You only need to update** if you want to use features from a newer protocol version (e.g., new RPCs added in protocol v2).
+
+**Version history:**
+
+| Version | RPCs | Notes |
+|---------|------|-------|
+| 1 | Initialize, Shutdown, HealthCheck, GetManifest, OnEvent, HandleHTTP | Initial release |
+
+**Pre-versioning plugins** (those that don't set `protocol_version` in their response) return `0`, which the server treats as version `1`. This means all existing plugins are compatible without changes.
+
 ## Configuration
 
 Plugins are configured in the server's `app.ini`.
