ASAR 完整性升级为稳定版
¥ASAR Integrity graduates to stable
"experimental" 的一项长期功能 - ASAR 完整性 - 现已在 Electron 39 中稳定运行。启用此功能后，它会在运行时根据构建时哈希值验证你打包的 app.asar 文件，以检测任何篡改。如果不存在哈希值或者哈希值不匹配，则应用将强制终止。
¥A long-standing "experimental" feature -- ASAR integrity -- is now stable in Electron 39. When you enable this feature, it validates your packaged app.asar at runtime against a build-time hash to detect any tampering. If no hash is present or if there is a mismatch in the hashes, the app will forcefully terminate.
有关此功能的工作原理、如何在应用中使用它以及如何在 Electron Forge 和 Electron Packager 中使用它的完整信息，请参阅 ASAR 完整性文档 文档。
¥See the ASAR integrity documentation for full information on how on the feature works, on how to use it in your application, and how to use it in Electron Forge and Electron Packager.
相关消息：Electron Packager v19 现在默认启用 ASAR。#1841
¥In related news, Electron Packager v19 now enables ASAR by default. #1841

重大变化
¥Breaking Changes
已弃用：--host-rules 命令行开关
¥Deprecated: --host-rules command line switch
Chromium 正在弃用 --host-rules 开关。
¥Chromium is deprecating the --host-rules switch.
你应该改用 --host-resolver-rules。
¥You should use --host-resolver-rules instead.
行为改变：window.open 弹出窗口始终可调整大小
¥Behavior Changed: window.open popups are always resizable
根据当前的 WHATWG 规范，window.open API 现在始终会创建一个可调整大小的弹出窗口。
¥Per current WHATWG spec, the window.open API will now always create a resizable popup window.
恢复先前行为：
¥To restore previous behavior:
webContents.setWindowOpenHandler((details) => {
return {
action: 'allow',
overrideBrowserWindowOptions: {
resizable: details.features.includes('resizable=yes'),
},
};
});
行为改变：共享纹理 OSR paint 事件数据结构
¥Behavior Changed: shared texture OSR paint event data structure
使用共享纹理离屏渲染功能时，paint 事件现在会发出结构更清晰的对象。它将 sharedTextureHandle、planes 和 modifier 合并为一个统一的 handle 属性。详细信息请参见 OffscreenSharedTexture 文档。
¥When using the shared texture offscreen rendering feature, the paint event now emits a more structured object.
It moves the sharedTextureHandle, planes, modifier into a unified handle property.
See the OffscreenSharedTexture documentation for more details.
