I hardly use Lightroom so I didn't mention it when I received notice that the new version of it has now been released. I assumed one of the many Lightroom users here at CiC would have brought it to everyone's attention by now, but that hasn't happened.
The branding of the subscription-based model is Lightroom CC and the branding of the perpetual license model is LR 6.
To review an explanation of the new capabilities, see this provided by the Lightroom Queen.
If you prefer buying or upgrading to LR 6 (the perpetual license), reports are that Adobe has done a pretty good job of hiding those options. Use the above link to access a link that provides information about how to easily to purchase the license.
The above link also provides information about how to purchase the subscription-based license.
To review a comparison of the subscription and perpetual license models, see this provided by Laura Shoe.
PLEASE do not turn this thread into a bashing of Adobe's subscription model. Thank you!
