"... adding functionality requested by users, including additional advanced imaging features..."
Thanks for posting which to me indicates that we don't have to wait too ling for LR6.
It looks like they are softening us up to the idea of 64-bit only, recent operating systems only, to mimimse the grumbling when they launch it.
Is anyone running 32-bit Windows?
I am now using LR4 but am thinking about getting a new camera which is only supported by LR5. If I upgrade to LR5 now rather than waiting for LR6, what is the likelihood that LR6 will come out the next week and I will feel like an idiot?
At this point I would buy the camera and use the DNG Converter in order to stay with LR4 a bit longer. Chances seem good that a LR6 Beta or RC will be along soon.
Thanks for the suggestions. Maybe as a public service I should upgrade to LR5 now so as to accelerate release of LR6 for everyone else's benefit.
