Release Notes for v45.0.0-alpha.5

Fixes

• File System Access permission requests and the file-system-access-restricted event are scoped to the requesting document, grants are reset when the origin's last page closes, and write access works in in-memory sessions. #53690 ^{(Also in 43)}
• Fixed Tray icons not appearing when running inside Flatpak or Snap sandboxes on Linux. #53654 ^{(Also in 44)}
• Fixed app.getGPUInfo('complete') stalling the GPU process for several seconds on some Windows systems. #53645 ^{(Also in 44)}
• Fixed session.setPermissionCheckHandler receiving the top-level origin and a null webContents for hid and usb checks made from a subframe. #53679 ^{(Also in 43, 44)}
• Fixed webContents.on(), removeListener() and removeAllListeners() throwing "Object has been destroyed" for console-message listeners after the WebContents was destroyed. #53495 ^{(Also in 42, 43, 44)}
• Fixed a crash on Linux when process.env was written while another thread was reading the environment, and a memory leak when a worker thread exits. #53508 ^{(Also in 42, 43, 44)}
• Fixed a possible crash on Windows when a file dialog was shown for a window that was being closed at the same time. #53586 ^{(Also in 42, 43, 44)}
• Fixed a renderer crash when the main process sent IPC to, or a page navigated, a same-process window.open() child whose contextIsolation differed from its opener's. #53538 ^{(Also in 42, 43, 44)}
• Fixed a spurious node_init error being logged when creating a ShadowRealm with Node.js integration enabled. #53578 ^{(Also in 44)}
• Fixed crashes in setDisplayMediaRequestHandler when the granted frame had been destroyed or another tab was granted by id. #53673 ^{(Also in 42, 43, 44)}
• Fixed several non-functional DevTools integrations: the Security panel's "View certificate" button, Ctrl+wheel zooming inside DevTools, and DevTools keyboard shortcuts (e.g. F8) while the inspected page has focus. #53471 ^{(Also in 43, 44)}
• Fixed window state not being persisted when a window entered or left fullscreen, or was maximized or unmaximized, without also being moved or resized. #53577 ^{(Also in 44)}
• openExternal permission requests started by a frame that has since gone away are attributed to that frame's origin rather than to the navigating page. #53696 ^{(Also in 42, 43)}
• pointerLock and keyboardLock permission requests now report the requesting frame, and execCommand('paste') requires user activation in the frame that calls it. #53692 ^{(Also in 44)}

Other Changes

• Electron's internal JavaScript bundles are no longer listed in require('module').builtinModules or loadable through process.getBuiltinModule(). #53624
• Fixed the app becoming unresponsive when a page has a very large number of app-region draggable elements. #53596 ^{(Also in 43, 44)}
• Improved throughput of responses that protocol.handle handlers return straight from net.fetch. #53379 ^{(Also in 44)}
