NW.js v0.44.0 Released with Chromium 80


I'm excited to release NW.js 0.44.0 in stable branch. It ships Chromium 80 and two new features: full page screenshot and silent autoprint.

A new API Window.captureScreenshot() is added to support full page screenshot. The full webpage beyond the visible area can be captured with it. See the document for more information and example.

The autoprint API Window.print() adds a silent option to hide the print window.

Chromium 80 contains usual under-the-hood performance and stability tweaks, but there are also some cool new features to explore. It supports Content Indexing, ECMAScript Modules in Web Workers, Compression Streams and more. V8 JavaScript Engine 8.0 adds Optional chaining and reduces heap by 40% via Pointer compression. Please check Chromium blog and v8 blog for details. For a complete list of all features (including experimental features) in this release, see the Chrome 80 milestone hotlist.

I've made the 0.44 branch ready soon after Chromium beta bumps to 80. Thanks to the testers for their valuable feedback and bug reports. I've been working on 2 branches simultaneously: a released branch on current Chromium stable and a beta branch on Chromium beta.

Best regards,
Roger Wang
