Left the catalogue this week

Observed by diffing the live catalogue every day. A model that simply stops being listed was never on anyone's calendar, because there was no date to put on one.

Dates the vendor withdrew this week

The vendor published a retirement date and its page no longer carries one. The model is still listed and still callable; what changed is what the vendor says about it.

nothing this week

The long tail nobody tracks

Models their vendor has already retired that the catalogue no longer lists at all. These are not this week's news - they are what is still sitting in code written last year.

Reading a list is work. This checks a whole repository against all of it:
