An image that has been altered by the artist to make corrections to it. (Be it inpainting, img2img, or first-party editing.) The changes may be minor (such as a missing mole) or they may be major (correcting for bad proportions, or adding censorship).
This tag should not be used unless there is a visual difference between the images. Images that differ only in resolution or compression level are duplicates, not revisions.
It also should not be used if the original non-revised image never existed on AIBooru.
has bad revision (for when a revision is available, but it is inferior to the image already on AIBooru)
has censored revision (for when a revision is available, but has been censored, most likely due to the artist accidentally posting an uncensored version)
