Also adding relnote request as per comment 5:

Release Note Request (optional, but appreciated)
[Why is this notable]: CSS filters are now available to canvas as well
[Suggested wording]: The Canvas2D filter property has been implemented. It provides filter effects like blurring or gray-scaling similar to the CSS filter property.

I think that the note on MDN is enough. Please need info me if you disagree
Depends on: CVE-2016-9077
I think this fix effect ctx.shadowBlur ?
I have been using a mixture of globalAlpha, shadowColor, and shadowBlur to blur text in my canvas elements. Since the release this technique is now failing, would the implementation of the blur filter be effecting it?
It's possible that the interaction with the filter code has broken something. Can you please file a new bug and attach a minimal testcase?
Will do
I found Bug 1306027, and added a link to my example[] there.
