Adobe Photoshop Lightroom 5.7.1 (released in 2014) is a legacy version, but it still offers several helpful features for photographers who prefer its classic workflow or have older hardware. Here are the standout features in this specific version:
Work on images without the original RAW files being present. Smart Previews are smaller, lossy DNG copies that let you edit full-resolution images when your external drive is disconnected—a lifesaver for laptop users.
With one click, Upright analyzes an image and corrects keystone distortion (e.g., converging vertical lines in buildings). It offers four auto modes (Level, Vertical, Full, Auto) plus manual fine-tuning.
The spot healing tool in 5.7.1 includes a feather slider to soften the edge of the repair, making it blend better than in LR4.
