Electron 团队很高兴发布了 Electron 6.0.0.0！ 您可以通过 npm 安装electron@later 或者从我们的 发布网站 下载它。 这次发布包含升级、修复和新功能。 We can't wait to see what you build with them! Continue reading for details about this release, and please share any feedback you have!

What's New​

Today marks a first for the Electron project: this is the first time we've made a stable Electron release on the same day as the corresponding Chrome stable release! 🎉

Much of Electron's functionality is provided by the core components of Chromium, Node.js, and V8. Electron keeps up-to-date with these projects to provide our users with new JavaScript features, performance improvements, and security fixes. Each of these packages has a major version bump in Electron 6:

This release also includes improvements to Electron's APIs. The release notes have a more complete list, but here are the highlights:

Promisification​

Electron 6.0 continues the modernization initiative started in 5.0 to improve Promise support.

These functions now return Promises and still support older callback-based invocation:

  • contentTracing.getCategories() #16583
  • contentTracing.getCategories() #16583
  • contentTracking.getTraceBufferUs() #16600
  • contents.executeJavaScript() #17312
  • cookies.flushStore() #16464
  • cookies.get() #16464
  • cookies.remove() #16464
  • cookies.set() #16464
  • dialog.showCertificateTrustDialog() #17181
  • inAppPurchase.getProducts() #17355
  • inAppPurchase.purchaseProduct()#17355
  • netLog.stopLogging() #16862
  • session.clearAuthCache() #17259
  • session.clearCache() #17185
  • session.clearHostResolverCache() #17229
  • session.clearStorageData() #17249
  • session.getBlobData() #17303
  • session.getCacheSize() #17185
  • session.resolveProxy() #17222
  • session.setProxy() #17222
  • webContents.hasServiceWorker() #16535
  • webContents.printToPDF() #16795
  • webContents.savePage() #16742
  • webFrame.executeJavaScript() #17312
  • webFrame.executeJavaScriptInIsolatedWorld() #17312
  • webviewTag.executeJavaScript() #17312

这些功能现在有两种形式，即同步和基于Promise的异步：

  • dialog.showMessageBox()/dialog.showMessageBoxSync() #17298
  • dialog.showOpenDialog()/dialog.showOpenDialogSync() #16973
  • dialog.showSaveDialog()/dialog.showSaveDialogSync() #17054

These functions now return Promises:

Electron Helper (Renderer).app, Electron Helper (GPU).app and Electron Helper (Plugin).app​

In order to enable the hardened runtime, which restricts things like writable-executable memory and loading code signed by a different Team ID, special code signing entitlements needed to be granted to the Helper.

To keep these entitlements scoped to the process types that require them, Chromium added three new variants of the Helper app: one for renderers (Electron Helper (Renderer).app), one for the GPU process (Electron Helper (GPU).app) and one for plugins (Electron Helper (Plugin).app).

Folks using electron-osx-sign to codesign their Electron app shouldn't have to make any changes to their build logic. If you're codesigning your app with custom scripts, you should ensure that the three new Helper applications are correctly codesigned.

In order to package your application correctly with these new helpers you need to be using electron-packager@14.0.4 or higher. If you are using electron-builder you should follow this issue to track support for these new helpers.

重大更改​

  • This release begins laying the groundwork for a future requirement that native Node modules loaded in the renderer process be either N-API or Context Aware. The reasons for this change are faster performance, stronger security, and reduced maintenance workload. Read the full details including the proposed timeline in this issue. This change is expected to be completed in Electron v11.

  • net.IncomingMessage headers have changed slightly to more closely match Node.js behavior, particularly with the value of set-cookie and how duplicate headers are handled. #17517.

  • shell.showItemInFolder() now returns void and is an asynchronous call. #17121

  • Apps must now explicitly set a log path by calling the new function app.setAppLogPath() before using app.getPath('log'). #17841

终止对 3.x.y 的支持​

Per our support policy, 3.x.y has reached end of life. 我们鼓励开发者将应用程序升级到更新的 Electron 版本。

应用反馈项目​

We continue to use our App Feedback Program for testing. Projects who participate in this program test Electron betas on their apps; and in return, the new bugs they find are prioritized for the stable release. If you'd like to participate or learn more, check out our blog post about the program.

接下来​

在短期内，您可以期待团队继续专注于跟上构成 Electron 的主要组件的开发，包括 Chromium、Node 和 V8。 尽管我们谨慎地避免对发布日期做出承诺，但我们的计划是大约每季度发布一次 Electron 的新主要版本以及这些组件的新版本。 暂定 7.0.0 时间表 展示了 Electron 7 开发生命周期中的关键日期。 Also, see our versioning document for more detailed information about versioning in Electron.
