So, first... this is the wrong place for this ticket.

You would want to file tickets about updates content in the rel-eng trac.

That said, the last 2 updates have no request, and won't be pushed anywhere until you request testing for them.

The first 3 are in a push that is currently ongoing. Thats why you can't unpush them. You must wait until that push is done, then you can unpush them and they will disappear from testing in the following push.

Hope that helps.

I understand, Kevin. Thank you!
