Photoshop ships with technology preview features that you can try out. These features may not be completely production-ready yet, so exercise discretion while using them.
Default state: On
Photoshop now features artificial intelligence-assisted upscaling to preserve important details and textures while resizing images without introducing distortions. In addition to skin tones and hair textures, this feature preserves harder-edged details like text and logos. Try it on soups, salads, pizza, and any other subjects that need that extra dash of texture preservation.

Opomba:
With Photoshop CC 20.0 (October 2018 release), Paint Symmetry now ships as a full feature and no longer a technology preview feature. See Paint symmetrical patterns for more information.
Default state: On
Photoshop now lets you paint symmetrically while using the Paint Brush, Mixer Brush, Pencil, and Eraser tools. While using these tools, click the butterfly icon () in the Options bar. Choose from the several available types of symmetry.
Paint strokes are reflected live across the line of symmetry, allowing for easier sketching of faces, cars, animals, and more.
You can set any path as a symmetry path. Right-click the path in the Paths panel and select Make Symmetry Path. To modify a symmetry path, select it and then choose > Transform Symmetry.
