Please tread with care—
Adobe is branching Lightroom into two versions: Lightroom Classic CC (aka just Lightroom Classic) and Lightroom CC.
Is this confusing? You betcha.
Please Do Not Change from old Lightroom CC (Now called Lightroom Classic CC) to Lightroom CC unless you really know what you are doing. Always best to wait a while with Adobe.
