+## Changes
+
+- Thread history now stays in sync across the chat toolbar, thread picker, and Threads view while loading older threads or refreshing.
+- Thread search now uses fuzzy title matching across the complete active history instead of matching thread IDs.
+- Running subagent summaries now show each agent's latest activity instead of only its initial status.
+- Opening the thread picker again now closes the previous picker, and accepted MCP links are preserved in conversation history.

+`release:prepare` updates version files and drafts `## Changes` from selected Conventional Commits since the previous version. Use those commits to locate candidate changes, then compare the resulting user-visible behavior with the previous release before choosing the version. Review the draft against the full diff for complete, user-facing notes; consolidate and reorder entries as needed, and replace an empty placeholder.
 
 Run `release:preflight` after the release commit is on `main`; it validates the commit range and release readiness.
