+
+### Fixed
+- **MCP transport stability**: Fixed critical issue where server logs written to stdout caused MCP transport disconnects. Logs now correctly route to stderr, preventing JSON-RPC stream corruption.
+
 ### Added
 - **Automatic counting in list_tasks responses**: New `returnedCount` field always shows how many items are in the current response
 - **Optional total count with includeTotalCount**: Set `includeTotalCount: true` in the filter to get `totalCount` (total matching items without pagination)

 - **Project completion filtering**: Filter projects by `completed`, `completedAfter`, `completedBefore` to find completed projects in time windows
 - **Automatic sorting by completion date**: Results sorted by `completionDate` descending when filtering by completion (matches OmniFocus Completed perspective)
 - **Enhanced get_task_counts**: Now supports full filtering including completion date windows for accurate time-window counts
+- **Regression test**: Added test to ensure MCP logs go to stderr not stdout
+
+### Removed
 - **Removed staleThreshold**: Removed deprecated convenience filter in favor of explicit date windows
-- Initial release with core MCP server functionality
-- OmniFocus plugin for automation
-- Timezone-aware queries
-- Project health analysis
-- Tag analytics
-- Stale task detection
