I think it's a bit harsh criticising the lack of progress in 6 over 5.
The HDR feature seems to work pretty well and has a good hit rate IME.
The pano feature isn't as poor as some here would have you believe. When it works, it works well and delivers decent workable files.
The FR was frequently asked for too. It's just a shame it's not as well implemented as one would hope for.
GPU acceleration was also requested a lot, but seems to be pretty much a dead loss.
So the above seem 'version one' features that might come to maturity in future upgrades.
The last two upgrades have also been dirt cheap, so there's not too much to moan about on that score either.
The real disappointment has been the lack of the little improvements that could make the program more usable, but don't make great headlines.
I have added the compare list of features between LR5 and LR6 and LRCC. Not much in LR6 and most of the list for LRCC compared to LR5 was in LR5 with CC subscription.
There's absolutely nothing at all that appeals to me in the CC offering over the LR6 feature set, so I can't see why people think it's a strategy to move people to CC by adding compelling new 'CC only' features.
