- **fixed** — Fixed chrome.tabs.query() returning tab url and title to extensions without the tabs permission or host access, aligning with tabs.get
- **fixed** — Fixed a renderer crash when an array with a throwing property getter is passed across contextBridge, and several main/utility-process crashes when option objects passed to Electron APIs contain throwing accessors or Proxy traps
- **fixed** — Fixed an intermittent crash at startup on Linux caused by a race between Pango and the main thread initializing fontconfig
- **fixed** — Fixed an issue where an exception thrown by a property getter on an object passed through contextBridge was swallowed instead of being thrown back to the caller
- **fixed** — Fixed main process crashes when navigating to http://accessibility/ or http://devtools/, when an extension background page used navigator.mediaDevices, and when calling SerialPort.forget() for a disconnected device
- **fixed** — Fixed the PDF viewer failing to save an edited PDF with NotAllowedError: Third party iframes are not allowed to show a file picker
- **fixed** — Fixed xdg-desktop-portal misidentifying Electron apps whose desktopName contains dashes, which broke globalShortcut and other portal-based APIs on Linux
