 ### Breaking Configuration Changes
 
-- **`custom` engine removed** (v0.46.1) - The `custom` engine type is no longer supported. Workflows using `engine: custom` must migrate to `copilot`, `claude`, or `codex`.
-- **`copilot-sdk` engine removed** (v0.46.1) - The `copilot-sdk` engine has been removed. Update any workflows referencing this engine.
+- **`custom` engine removed** - The `custom` engine type is no longer supported. Workflows using `engine: custom` must migrate to `copilot`, `claude`, `codex`, or `gemini`.
+- **`copilot-sdk` engine removed** - The `copilot-sdk` engine has been removed. Update any workflows referencing this engine.
 - **Status Comments**: Status comments must now be explicitly enabled with `status-comment: true`. Previously coupled with `reaction`, now independently configured.
 - **Temporary ID Format**: Changed from `aw_` + 12 hex chars to `aw_` + 3-8 alphanumeric chars. Update references in existing workflows accordingly.
