NW.js v0.20.2 Released

[Roger Wang]

NW.js 0.20.2 is here with multiple bug fixes on the stable branch.

Previously we launched 0.20 based on Chromium 56, which contains under-the-hood performance and stability tweaks, and some cool new features to explore like CSS position: sticky and Web Bluetooth. See the upstream announcement for more information. NW20 also features V8 5.6, which delivers a number of key improvements in memory and performance footprint, as well as Ignition and TurboFan pipeline for ES.next. This version is going to ship the WebAssembly browser preview, which is a new runtime and compilation target for the web. Please refer to the dedicated upstream blog post for further information.

Chromium 56 introduces an optimization to save CPU when tabs are in the background. It's done by throttling background tabs' timers. See this blog post for more information. If you don't want this in your NW.js application, you can use the --disable-raf-throttling switch to disable it.

We've been working on 3 branches simultaneously: a released branch on current Chromium stable, a beta branch on Chromium beta and a 0.14 branch for legacy OS support.

For more information on the new milestone 0.13 and later versions, please see our blog "What's New in 0.13" for a better introduction.
