Google Antigravity 2.4.2

What's new in this version:

Improved:
- 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 interface responsiveness by preventing unnecessary re-renders when toggling sidebars or auxiliary panes
- Improved accessibility in the Settings modal with better heading hierarchy and keyboard focus management
- Updated the default settings screen name from 'Agent' to 'General' and updated copy for inherited settings ('Use Global' to 'Inherit General')
- 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:
- 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
- Added view options (grouping, sorting, filtering) and fixed search filtering on the Conversation History page
- Fixed an issue where the app doesn't request microphone permission when enabling "Record Audio" for the first time
