 ### Added
 
 - Automatic changelog viewer on startup in interactive mode. When starting a new session (not continuing/resuming), the agent will display all changelog entries since the last version you used in a scrollable markdown viewer. The last shown version is tracked in `~/.pi/agent/settings.json`.
+- OpenRouter Auto Router model support ([#5](https://github.com/badlogic/pi-mono/pull/5))
 
 ### Changed
 
 - **BREAKING**: Renamed project context file from `AGENT.md` to `AGENTS.md`. The system now looks for `AGENTS.md` or `CLAUDE.md` (with `AGENTS.md` preferred). Existing `AGENT.md` files will need to be renamed to `AGENTS.md` to continue working. (fixes [#9](https://github.com/badlogic/pi-mono/pull/9))
+- **BREAKING**: Session file format changed to store provider and model ID separately instead of as a single `provider/modelId` string. Existing sessions will not restore the model correctly when resumed - you'll need to manually set the model again using `/model`. (fixes [#4](https://github.com/badlogic/pi-mono/pull/4))
+
+### Fixed
+
+- Fixed markdown list rendering bug where bullets were not displayed when list items contained inline code with cyan color formatting
