Under a right click on a video in the media pool. I did that many times in the past, and I really don't remember going anywhere else than the menu of the clip itself.
I looked at the right click menu 20 times to be sure I wasn't missing something. So used to have it at the same place for years. And even with reading the menu line by line I didn't caught the "clip operations".
But hey, they do that all the time with updates, they don't put all the changes in the changelogs - and they should!
It's not that hard to have a complete and accurate changelogs.
