Deprecations and removals in Chrome 87
Comma separator in iframe allow attribute
Permissions policy declarations in an <iframe> tag can no longer use
commas as a separator
between items. Developers should use semicolons instead.
-webkit-font-size-delta
Blink will no longer support the rarely-used -webkit-font-size-delta property. Developers should use font-size to control font size instead.
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. In Chrome 86, FTP was turned off for pre-release channels (Canary and Beta) and was experimentally turned off for one percent of stable users.
The remaining capabilities of Google Chrome’s FTP implementation are restricted to either displaying a directory listing or downloading a resource over unencrypted connections.
Remainder of the deprecation follows this timeline:
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.
