- Added a keyboard shortcut (Cmd+L / Ctrl+L) to quickly quote selected text into the chat input.
- Added support for attaching.json and.md files to the input box with distinct visual badges.
- Added preview (temporary) tabs to the auxiliary pane, allowing files to open in a temporary slot that is reused until promoted to a permanent tab (e.g., via double-click).
- Added a timeout for MCP server connections and tool calls to prevent the agent from hanging indefinitely.
- Added an 'Only Unread' filter option to the Conversation History dropdown.
- Added support for uploading and attaching CSV (.csv) files in chat as plain text.
- Added a 'Download Diagnostics' command to the command palette to download a diagnostics package (containing logs and agent state) for troubleshooting.
- Added tooltips to file links in markdown views, showing their full path on hover.
- Refined command approval rules to reduce redundant permission prompts for everyday tools.
- Improved the speed of conversation switching by optimizing trajectory summary list selectors.
- Improved authentication error messages to show the specific failure reason.
- Draft comments are now automatically saved and preserved across sessions.

- Improved accessibility in the Settings modal with better heading hierarchy and keyboard focus management.

- Restored the default 5-second auto-dismiss behavior for in-app notifications.
- Optimized scroll performance in conversation lists and panels, especially during long chats.
- Fixed an issue where configuring duplicate tool names in customizations (such as MCP servers) caused the agent to fail to initialize.
- Fixed a potential crash in the image generation tool.
- Fixed a bug where terminal commands with quoted arguments (e.g., arguments containing pipes or special characters) were incorrectly parsed, which could cause permission checks to fail or behave unexpectedly.
- Fixed an issue where queued agent messages could be delivered and displayed out of order on Windows clients.
- Fixed an issue where live-streamed subagent steps would display as generic text instead of rich cards.
- Fixed an issue where inline markdown diff blocks could occasionally render as empty boxes.
- Fixed a bug where the Settings dialog would close unexpectedly when clicking outside an open dropdown.
- Fixed an issue where the UI would show an infinite loading spinner instead of falling back to agent edits when version control features were unavailable.
