I'm a VIP Wrangler with the WordPress.com VIP team and I'm commenting on behalf of Automattic:

Folks, we’re sorry that it looks as though we’ve abandoned Edit Flow. We certainly haven’t, and we should have at least updated the tested tag for the plugin as you rightly point out.

We’ve done that today, as well as make sure Github and WordPress.org are in sync.

(Note the WordPress.org page hasn't updated as I type.)

Internally I’m working on an effort to make Automattic better at maintaining our own plugins. We want to avoid this situation as much as we can, and I promise we’re trying.

Thank you for calling us out on this. Let’s see what we can all do about getting some attention for Edit Flow.
