- Fix //tmp issue: distinguish slash commands from file paths by checking if anything precedes the /
- Fix symlinks to directories (like /tmp) not getting trailing slash

 ## [Unreleased]
 
+## [0.25.1] - 2025-12-21
+
+### Fixed
+
+- **Gemini image reading broken**: Fixed the `read` tool returning images causing flaky/broken responses with Gemini models. Images in tool results are now properly formatted per the Gemini API spec.
+
+- **Tab completion for absolute paths**: Fixed tab completion for absolute paths like `/tmp` producing `//tmp`. Also fixed inability to continue tabbing through subdirectories after completing an absolute path.
