Regex Changes in Latest Versions?

So in the latest versions of Grafana, it appears how regex is interpreted has changed. I have a list of items I want to filter for a graph, for example:

CPU Nice Time
CPU Steal Time
CPU User Time
CPU Idle Time
Processor Load
Iowait time

And I want to build a graph that just shows all the CPU items, but not the CPU Idle Time.

This used to work: /CPU (?!idle)/

What is the best way to do this now?

Thank you!

hi @jedthehead

just confirming: are you talking about the value mapping by regex feature? Or is this regex inside a query-editor? thx
