What is "Restart flow" in Webforms? And "Get URL" removed from the three dot ellipse menu?

I noticed a “Restart flow” button in the upper right hand corner of the web form screen (after clicking on an existing web form from the templates tab → My Web Forms.) Is it new? What does it do? I couldn’t find anything about it in the last few release notes. Also, I needed to get an activated webform URL, but could only get it after clicking on the “Use” button. Are there release notes on the recent webform updates? Thanks in advance for any guidance. I hadn’t had to make any updates to my webforms since earlier in the year, and noticed some of these changes.
