New Sleep Feature Notification but Where?

When I opened Channels today, I got an amazing message that I can now set a sleep timer but I cannot find any reference to this feature in any menu during playback, in settings, or here on the forum. There were two other announcements related to temporarily disabling auto play and stats for nerds.

Where is the documentation on how to access these neat new features?

Swipe down in the player to access the new Options tab

That was where I looked first and swear it wasn't there! But, I looked again and I see it. I'm sorry I was that user. UGH! Thank you!
