 ## [Unreleased]
 
+### Added
+
+- **`/clear` Command**: New slash command to reset the conversation context and start a fresh session. Aborts any in-flight agent work, clears all messages, and creates a new session file. ([#48](https://github.com/badlogic/pi-mono/pull/48))
+
+### Fixed
+
+- **Markdown Link Rendering**: Fixed links with identical text and href (e.g., `https://github.com/badlogic/pi-mono/pull/48/files`) being rendered twice. Now correctly compares raw text instead of styled text (which contains ANSI codes) when determining if link text matches href.
+
+## [0.8.5] - 2025-11-21
+
+### Fixed
+
+- **Path Completion Hanging**: Fixed catastrophic regex backtracking in path completion that caused the terminal to hang when text contained many `/` characters (e.g., URLs). Replaced complex regex with simple string operations. ([#18](https://github.com/badlogic/pi-mono/issues/18))
+- **Autocomplete Arrow Keys**: Fixed issue where arrow keys would move both the autocomplete selection and the editor cursor simultaneously when the file selector list was shown.
+
 ## [0.8.4] - 2025-11-21
 
 ### Fixed
