Coming three and a half months after GIMP 2.10.18, the GIMP 2.10.20 release is here to introduce non-destructive cropping. The new feature is enabled by default in this version and works by resizing the canvas instead of cropping out the actual pixels. The benefits of the non-destructive cropping feature is that you can revert the cropped image at any time, even if you quit GIMP if you save the project as an XCF file, and the cropped image will reflect exactly what you see within the canvas boundaries of the Crop tool.
