It appears that Adobe is moving toward a subscription only based model. In my case, the Adobe Creative Cloud Photography bundle at $9.99 per month worked out. However, you still have a choice with Lightroom 6 although I think losing the mobile features would be a major detriment.
The major improvements in this new release included: HDR Merge, Panorama Merge, Performance improvements, Facial Recognition, Filter Brush Improvements, Adding to Collections on Import, Slideshow Improvements, CMYK now supported in soft-proofing an Pet Eye Removal.
While the performance enhancements are hidden from view they are remarkable. In my limited use of the new product I have seen up to a 200% increase in speed on some tasks.
You can now perform an HDR Merge from within Lightroom and it is impressive in its simplicity (as compared to third-party products) and its speed of operation. I tested the feature with some of my HDR images and it worked great. One of the great features of the HDR Merge is that the output is to a DNG file (in other words, it is a full dynamic range RAW file that you can adjust and enhance in Lightroom just like a regular image).
Another new feature of the new Lightroom is Panorama Merge directly from Lightroom.
This is such an amazing implementation that it seems like it has very few limitations. I saw today a post that said a photographer had created an amazing medium format, 18 photo, HDR panoramic image in Lightroom 6. This file ended up being 705 megabytes in size. See the story at: http://resourcemagonline.com/2015/04/i-just-made-a-medium-format-18-image-hdr-panoramic-image-with-lightroom-6/51338/
The next major feature of the new Lightroom is Face Tagging or Facial Recognition. This is an extensive feature set that allows you to identify and tag people in your photos. It would be very helpful for those sports shooters that have to caption their images for production.
While the process to set up the facial recognition seems a little cumbersome I think it might be useful in some situations.
Other improvements were made to the Slideshow module with the ability to pan and zoom into a slide making it look even more professional and to allow extensive new music options. You can now add to an existing collection as you are importing your images. Those of you who take pet photos now will have a feature (in the Red Eye Removal section) to remove those glowing eyes in your pet photos. And finally you can now do a soft proof with a CMYK color space.
All in all this is a significant upgrade to the Lightroom brand and continues on a path to have Lightroom be able to do almost everything that you need to do as a photographer in one package.
One strange thing happened when I first installed Lightroom CC. It would not run! Several people reported the same thing and it did not matter whether you were on Mac or PC. Adobe has posted a simple fix to the problem and it worked for me: https://forums.adobe.com/thread/1822807
