In reply to Climbing Pieman:
Very disappointing - but hardly unexpected. Currently I have LR6, and fortunately my RAW files are all in DNG format - I shoot with Pentax.
So I won't need to upgrade LR for any new camera purchases, not that I am considering any in the near or indeed medium term.
I really like Lightroom, and on my current kit it is fast and stable, so my thinking is that I'll just stay as I am on LR6 for a number of years. Maybe somewhere down the line I will consider moving to something else, but I dislike Adobe's subscription model, so not going to be going there anytime soon.
