NW.js v0.102.0 Released with Chromium 139

2025/07/31

I'm pleased to announce NW 0.102.0 with Chromium 139 stable upgrade. Per upstream, Chromium 139 requires at least macOS 12.

In NW v0.102, Chromium 139 contains usual under-the-hood performance and stability tweaks, but there are also some cool new features to explore. It supports new CSS features, async attribute for SVG script elements, On-device Web Speech API and much more. Please check upstream release notes for details. For a complete list of all features (including experimental features) in this release, see the Chrome 139 milestone hotlist.

I've made the 0.102 branch ready soon after Chromium beta bumps to 139. Thanks to the testers for their valuable feedback and bug reports. I've been working on 2 branches simultaneously: a released branch on the current Chromium stable and a beta branch on Chromium beta.

Best regards,
Roger Wang
