Dear all,

In the interests of iterating more quickly, the editors of the Web 
Animations specification decided to defer the animation group and 
animation sequence features from Web Animations to the next level of the 

We believe these grouping primitives are still very powerful and 
important but that the first level of the specification should focus on 
exposing the existing features of the platform.

Furthermore, we are keen to see more and more of the Web Animations API 
ship this year which suggests we focus on stabilising the core features.

As a result, the current Editor's Draft[2] no longer includes animation 
groups or animation sequences. However, we continue to build a level 2 
specification[3] at the same time and from the same sources which 
includes these features. We hope this means that level 2 can ship soon 
after level 1.

At the same time, I have also moved the animation node-specific playback 
rate to level 2. This is because it is of little use without groups and 
is likely to confuse authors because there also exists a playback rate 
on players. This was resolved last November 2014.[4]

It's quite possible that in the process of splitting the spec I've 
introduced new bugs or that further simplifications are now possible. 
Please feel free to file issues on the spec[5] as you notice them, or 
report them here.

Best regards,
