[Beta] Where are the Publish and Unpublish buttons?

I am lost too at pushing modifications to published version.
What are the correct steps?
I found these, but I ask Anvil Central if this is the correct sequence.
Ok let’s assume I modify my code.
Old IDE: Save version → Publish
New IDE:
firefox_5xAy9HKK0q

  1. while on “master”, click commit
  2. change branch to “published”
  3. right-click on last commit
  4. choose “Reset published branch to here” (reset sounds like we’re zapping away our published branch history…)

OR

  1. choose “Merge” and in the popup we see we’re merging INTO published branch

What’s the correct way to publish?

As @stefano.menci noted, I cannot see any “Publish” menu voice either.
