NW.js 0.22.1 is here with Chromium 58 update. Since the patents on MP3 decoding are expired in the last month, NW.js enables the mp3 decoding support in this version.
Chromium 58 contains under-the-hood performance and stability tweaks, and some cool new features to explore like IndexedDB 2.0 and an improvement to iframe navigation. See the upstream announcement for more information. We've made the 0.22 branch ready soon after Chromium beta bumps to 58. And 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.
