Saved with the link. Notes from 2007 to 2016 are mostly the page's own words, so this is probably an excerpt.
With this release, our goal was to add some highly-desired features that allow photographers to quickly process and enhance their images. Weve added more robusthealing options, the ability tocreate off-center vignettes, and a one-click autoperspective correctiontool. Weve also added the ability to edit photos when not connected to your original images. Each of these improvements is a result of feedback provided by the Lightroom community. Thank you.
