Release Notes for v44.0.0-beta.5

Fixes

• Fixed registerFileProtocol and registerHttpProtocol returning readable responses to cross-origin no-cors fetches; they now return opaque responses like protocol.handle. #52852 (Also in 41, 42, 43)
• Fixed a WebContentsView staying blank after its window is shown when setBackgroundThrottling(false) was called while the window was hidden. #52863 (Also in 42, 43)
• Fixed a crash when resolving a path inside a malformed ASAR archive that contains cyclic link entries. #52858 (Also in 42, 43)
• Fixed a crash with app.setLoginItemSettings if a non-UTF8 service name is used. #52801
• Fixed a memory leak when creating BrowserWindows. #52894 (Also in 42, 43)

• Fixed custom V8 snapshots (electron-mksnapshot, and the loadBrowserProcessSpecificV8Snapshot fuse) having no effect in the main process on macOS arm64, Linux x64 and Windows x64. #52878 (Also in 42, 43)
