NW.js v0.29.0 Released with Chromium 65 Upgrade, Capturing and Offscreen Support
We're excited to announce NW.js 0.29.0 with Chromium 65 stable upgrade, 45 security updates within it and Node.js 9.7.1. The new feature included in this release is tab capture, offscreen rendering and experimental Widevine CDM support.
New Features: Tab Capture, Offscreen Rendering, Widevine CDM
The new supported API captures visible area of web contents, or creates a off-screen web contents with a given URL. Once the capture is started, it returns a Media Stream object which you can view live in a video element, make a screenshot with the MediaStream Image Capture API, or send it over the network through WebRTC.
In terms of performance the solution in NW should be superior than many other (OnPaint based) solutions as we're using the latest architecture inside Chromium. It's also supports more usage scenarios such as accelerated graphics/video and plugins elements etc.
To enable the Widevine CDM support, just put the plugin ('WidevineCdm' directory of Chrome) in the directory of NW. This feature is still experimental. There is ongoing discussion here.
What's New in Chromium 65
Chromium 65 contains usual under-the-hood performance and stability tweaks, but there are also some cool new features to explore. It supports CSS Paint API, the ServerTiming API, CSS
display: contents property and many more. Please check upstream information for details. For a complete list of all features (including experimental features) in this release, see the Chrome 65 milestone hotlist.
We've made the 0.29 branch ready soon after Chromium beta bumps to 65. Please try it and give your valuable feedback. We've been working on 2 branches simultaneously: a released branch on current Chromium stable and a beta branch on Chromium beta.
