FW 3.0 is Out

Yes but still no sleep widget :/

It will add like the my day and health stats I guess.

have a look at DC Rainmakers review of the 745 - sleep will come but at a later stage.

What has changed? Where can I find the release notes?

Are there any release notes available? Or what has changed?

Sleep widget was removed due to an error. It shoud be released in future FW.

I tried to find. I was unsuccessful. 3.0 versions I thin It should be similar with beta firmware 2.64. DO you have notes for it?

Yes 

but why is it released to all beta softwares on fenix 6 etc and it is removed from 745 ? 
the hardware is not that mich different - also why are there no updates on the 745 forums from any Moderator ? 
the Watch is out 1.5 weeks now and there is no word about that bug or when the sleep widget will be back ? 
not a word about 3.0 changelogs ? 

It's been on the Fenix 6 for a while now and is therefore not a part of the latest 11.75 beta update for those watches.  I've had the sleep widget on my F6 since at least 11.10 which came out over a month ago.

I still don’t have 3.0...
