How to detect that a scheduled entry has been published?

[goraxan]

I need to notify users when a new entry is published, if the entry is published (status = Live) from the begining I can detect it easily, by checking the firstSave attribute at the Entry::EVENT_AFTER_SAVE event and checking that the status is Live.
The problem comes when the entry is first saved schedule ti be published in the future (with a post date in the future, meaning it's saved with a status = Pending).

When the entry is automatically published, I can't detect it. I've tried to use $entry->isAttributeDirty('status') in the EVENT_AFTER_SAVE event in order to see if that attribute changed but it looks like it's always false.

Any ideas?

This module can be used to track the moment an entry goes live.
