Somebody who shall be nameless from a company we all know and love, today mentioned a tool available to analyse a setup against a new release, and flag all conflicts, schema changes, deprecated nuts and bolts, etc; then quickly backpedaled and said he’d better be careful what he said and wasn’t sure. Someone senior to him coughed meaningfully (or maybe I imagined that 
) .
Anyhow, it definitely caught my attention and I wonder if anyone else knows what that might be? I haven’t actually followed up and asked for it, but it sure sounds cool.
