• Added a Windows Error Reporting helper (electron_wer.dll, renamed to <app>_wer.dll alongside the executable) so crashReporter captures __fastfail and other crashes that bypass the in-process handler on Windows. #53851

• Fixed a memory leak on Windows when app.getPreferredSystemLanguages() was called. #53869 ^{(Also in 43, 44)}
• Fixed a potential UAF in app.getPreferredSystemLanguages() on Windows. #53864 ^{(Also in 43, 44)}
• Fixed a renderer crash when an iframe was removed right after loading with nodeIntegrationInSubFrames enabled and sandbox disabled, e.g. on pages that embed Meta Pixel. #53883 ^{(Also in 42, 43, 44)}
• Fixed helper executables on macOS starting a second app instance when launched without a process type, for example through child_process.fork() with the runAsNode fuse disabled; fork() now throws in that configuration. #53839 ^{(Also in 44)}

• Deprecated the synchronous safeStorage.isEncryptionAvailable(), safeStorage.encryptString() and safeStorage.decryptString() in favor of isAsyncEncryptionAvailable(), encryptStringAsync() and decryptStringAsync(). #53850
• Improved the performance of fs operations and require() on files inside asar archives. #53919
• Improved the performance of building and showing menus. #53914
