I tried searching and I didn't see any reference to this in any of the online product docs. If I missed it, please instruct me and chastise appropriately.
I noticed something new when I updated a custom command I had written, back in version 2.0.2, now imported on version 2.2. When I hit the discover parameters, I noticed this pipeline variable in the param definition tab. First, did I some how cause this to happen by doing something wrong or is this part of some new feature I need to learn about.
Thanks everyone.
