Google announced that support in Chrome for "plan-b" SDP semantics will be removed this August:

As I understand it, this means that FS' verto js library will stop working unless it's updated to use "unified-plan" semantics.

I searched github and google for "verto" and "jquery.verto.js" to see if I'd missed an announcement that this change was in-progress or done, but I don't get a good match at either. Has it been moved out of https://github.com/signalwire/freeswitch to a community repo? Does it have a maintainer?

I can't become the maintainer, but this is a serious problem for us if we don't have a solution by August.

Btw, Brian, thank you for your answer about HLS.
