Where Are WebView/Chromium Release Notes?
It took me a few searches to find detailed release notes for Android WebView/Chromium, so I thought I'd share a couple of links that others may find useful.
Detailed release notes by version can be found on the Chrome Status Web Platform Features page. Click the version number on the left to see features and fixes included in each release. You can also see proposed and in-development features.
And news about major updates across all of Google Chrome can be found on their Chrome Releases blog.
