Schmitz Adobe has released the standalone Lightroom 6.6 and [1]Lightroom CC 2015.6 (available as part of Adobe's Creative Cloud Photography plan) with a new feature for Creative Cloud members only. The Guided Upright tool enables Lightroom CC 2015.6 to straighten images, fix horizons, and reduce or eliminate the keystone effect in buildings (see this [2]YouTube video from the Lightroom team for a brief tutorial). Both editions of Lightroom ensure that Merge to Panorama and HDR works properly with Smart Previews, adds a Pending Sync Activity to the mobile section of Lightroom Preferences, add support for new cameras (Canon PowerShot G7 X Mark II, Leica M-D (Typ 262), Nikon COOLPIX B700, and Panasonic DMC-GX85) and tethered cameras (Canon EOS-1D X Mark II, Canon EOS 80D, and Canon EOS 1300D / Canon Rebel T6), add lens profile support to over 60 lenses, and fix numerous bugs. ($9.99 monthly subscription or $149 for the standalone app, free update, [3]release notes, 10.8+ for Lightroom CC 2015.6 and 10.9+ for standalone Lightroom 6.6) References 1. http://www.adobe.com/products/photoshop-lightroom.html 2. https://youtu.be/jlp8iXoWvU8 3. https://blogs.adobe.com/lightroomjournal/2016/06/lightroom-cc-2015-6-now-available.html .
