 **Authentication**: Not required for read-only access
 
 **API Versions**:
-- `/v0/` - Development version with latest features (may receive additive changes)
+- `/v0/` - Development version with latest features (may receive breaking changes)
 - `/v0.1/` - Stable version (only backward-compatible changes)
 
 **Recommendation**: Use `/v0.1/` for production applications requiring API stability. Both versions currently have identical functionality.
+We may add breaking changes _only_ to `/v0/` in the future, and we reserve the possibility of deprecating `/v0/` entirely.
 
 **Core endpoints:**
 - **`GET /v0.1/servers`** - List all servers with pagination
