Deprecations and removals in Chrome 86

Web Components v0 was removed from desktop and Android in Chrome 80. Chromium 86 removes them from WebView. This removal includes Custom Elements v0, Shadow DOM v0, and HTML Imports.
Deprecate FTP support
Chrome is deprecating and removing support for FTP URLs. The current FTP implementation in Google Chrome has no support for encrypted connections (FTPS), nor proxies. Usage of FTP in the browser is sufficiently low that it is no longer viable to invest in improving the existing FTP client. In addition, more capable FTP clients are available on all affected platforms.
Google Chrome 72 and later removed support for fetching document subresources over FTP and rendering of top level FTP resources. Currently navigating to FTP URLs results in showing a directory listing or a download depending on the type of resource. A bug in Google Chrome 74 and later resulted in dropping support for accessing FTP URLs over HTTP proxies. Proxy support for FTP was removed entirely in Google Chrome 76.
The remaining capabilities of Google Chrome’s FTP implementation are restricted to either displaying a directory listing or downloading a resource over unencrypted connections.
Deprecation of support will follow this timeline:
Chrome 86
FTP is still enabled by default for most users, but turned off for pre-release
channels (Canary and Beta) and will be experimentally turned off for one percent
of stable users. In this version you can re-enable it from the command line
using either the --enable-ftp command line flag or the
--enable-features=FtpProtocol flag.
Chrome 87
FTP support will be disabled by default for fifty percent of users but can be enabled using the flags listed above.
###Chrome 88
FTP support will be disabled.
