Electron 2.0.0 released

After more than four months of development, eight beta releases, and worldwide testing from many apps' staged rollouts, the release of Electron 2.0.0 is now available from electronjs.org.

Electron 2.0.0 released

Release Process

Starting with 2.0.0, Electron's releases will follow semantic versioning. This means the major version will bump more often and will usually be a major update to Chromium. Patch releases should be more stable because they will contain only high-priority bug fixes.

Electron 2.0.0 also represents an improvement to how Electron is stabilized before a major release. Several large scale Electron apps have included 2.0.0 betas in staged rollouts, providing the best feedback loop Electron's ever had for a beta series.

What is Electron?

Electron (formerly known as Atom Shell) is an open-source framework developed and maintained by GitHub. It was created in 2012 by Cheng Zhao while interning at Intel, in an attempt to work around the problems of node-webkit, a similar framework. Electron allows for the development of desktop GUI applications using front and back end components originally developed for web applications: Node.js runtime for the backend and Chromium for the frontend. Electron is the main GUI framework behind several notable open-source projects including GitHub's Atom and Microsoft's Visual Studio Code source code editors, the Tidal music streaming service desktop application and the Light Table IDE, in addition to the freeware desktop client for the Discord chat service and Spotify.
