What's new in v1.0.20

Highlights
- Added a /security-review slash command to start a security review of the current diffs.
- In local sessions, you can now edit a previous message to rewind the conversation and resend it as a new turn.
- Nested sessions in the sidebar now show connected hierarchy lines between parent and child rows for easier scanning.
- Simplified the loading state of the pull request checks panel to show a single animated header instead of duplicate loading indicators.

Added
- Added a /security-review slash command to start a security review of the current diffs.
- In local sessions, you can now edit a previous message to rewind the conversation from that point and resend it as a new turn.

Changed
- Nested sessions in the sidebar now show connected hierarchy lines between parent and child rows, making it easier to scan deeper session relationships.
- Simplified the loading state of the pull request checks panel to show a single animated header instead of a duplicate loading message and skeleton.

Fixed
- Clicking the header of a session plan file in the diff view now opens the Plan tab instead of doing nothing.
- Collapsed project rows in the sidebar keep their project icon for working, paused, or completed sessions, only replacing it when a session needs input, is interrupted, or has failed.
- Collapsed repository groups in the sidebar now keep showing the repository icon when all sessions are completed or ready to merge, instead of looking like a single session.
- Fixed a spurious "Model changed to..." message appearing in the transcript when resuming a session with an unchanged model.
- Fixed agent merge getting stuck and not re-prompting after a required check finished running while another check was still failing.
- Fixed empty draft sessions sometimes remaining after leaving the multi-session grid view
- Fixed pull requests briefly jumping out of "Ready to merge" in the sidebar while a merge was in progress before landing in "Done".
- Fixed repository labels in the sidebar fading too early; hover and keyboard actions now only reserve space when revealed
- Fixed the auto-merge agent sending unnecessary follow-up replies triggered by its own previous comments on a pull request.
- Fixed the line-selection hint in the file header overlapping the toolbar buttons on narrow panels
- Fixed the project removal confirmation dialog remaining visible after deleting a project in Settings.
- Fixed the pull request author sometimes appearing as their own reviewer in the Reviewers panel.
- Improved screen reader support in the Health Check dialog: diagnostic rows now announce their labels and pass/warning/error status, and copy-path buttons have distinct, descriptive names.
- The Create PR action no longer appears for a workspace after a pull request has already been created for it.
