Are you referring to "move fast and break things"?
If so, it's definitely newish for those of us who started programming twenty+ years ago. Back then waterfall was the way to develop applications. Once it was burned to CDs or DVDs, that was it. We could not afford shipping broken things.
Ever since internet became ubiquitous we moved to on-the-fly patching for installed software and fast deployment cycles on cloud.
That said, the lack of forethought in design and backward compatibility is nowadays definitely on the rise and occurs likely on an order of magnitude more often.
