In the next few days I intend to turn on the Element.getAnimations() and
Document.getAnimations() functions by default for release channels.
This feature allows developers to fetch and manipulate animations generated

Hi,
As of some time next week (week of Mar 2) I intend to turn on the following
two Web Animations API features by default for release channels:
* Implicit to/from keyframes (e.g. elem.animate({ opacity: 0 }, 500) to
fade out an element).
* Automatically removing filling animations that have

trigger indefinitely-filling animations in a manner that effectively leaks
memory. Recently-specified automatic removal behavior requires user agents

As per my recent "Intent to ship: Web Animations core interfaces"[1], we do
not intend to ship Animation composite modes until various spec work has
been completed.
However, when we implemented this feature, although we implemented it

As of 19 July or thereabouts, I intend to turn on the Web Animations core

* Animation finish / cancel events

suitability of the frames() name.[1]
In order to allow the standards discussion to play out without being bound
by shipping implementations, Chrome have decided to abort shipping their

There used to be a steps-middle timing function which is what the

Hi,
Today I was digging through the test expectations in
web-platform-tests/meta and came across some failure annotations for
tests added to w-p-t by Blink engineers that were since synced to m-c.
Looking into them, one of them turned out to be a real bug in our
code.[1]
Apart from being stoked
Hi,
It seems like the MANIFEST.json for web platform tests now includes a
checksum of test file contents. As a result, if you run './mach
web-platform-tests --manifest-update yer' on a clean checkout of m-c
you're likely to get a bunch of changes to MANIFEST.json showing up.
Should we be

No, you can't. We explicitly forbid that, precisely because of
