Re: SVG pathSegList Deprecated via Chrome's version 48 TODAY!

Hi Philip,

It seems to me that the SVG2 updates via Chrome will take a few years to
complete. Chrome and developers will need a specific location to announce
and communicate. The best place for this to occur would be at
http://www.chromium.org/developers/discussion-groups
Merely include the group : Chromium-SVG.
Even following the SVG2 process, this could endure for any future SVG
changes. Believe me, the word will get out that any/all discussions for
Chrome's SVG will happen here. This should make the SVG transitions a
seamless and positive process for Chrome, allowing developers to appreciate
and understand Chrome's strategies relative to SVG.

Regards,
Francis
