Adobe released Adobe Lightroom CC 2015.8 (and 6.8) and Adobe Converter Raw (ACR) 9.8. These new versions include support for the Nikon D5600, the 70-200mm f/2.8E FL, four Sigma Art lenses, the Tamron 150-600 with and without converters, and three Zeiss Milvus lenses.
Other new supported products include the Canon EOS M5, Fujifilm X-A3, Hasselblad X1D, Leica TL, Olympus E-M1 Mark II and E-PL8, the Panasonic Z2500, the Pentax K-70, Sony A6500 and A99 Mark II, the Sony RX-100 Mark V, and recent Google and Samsung phones shooting in raw.
In addition, Lightroom now has a “reference view” mode in the Develop module that allows you to compare two different images, which helps in processing to a consistent color/style. Smart Collections can now be filtered or created based upon whether images have Snapshots associated with them. You can export a Collection Set as a new catalog.
As usual, there are bug fixes and performance improvements. The full description is on the Adobe blog.
