It’s live! :slight_smile: We should update the ‘spec’ link on

Nice diff view

I updated to say that 04 is now the live spec, and changed the ‘Spec’ link in the header of to point to the data tracker, so you can see all versions from there.


Tweeted on the Twitters as well now.

Want to post it to the Unhosted mailing list, too?
