The dependency graph now handles updating image users to point to the current frame, and tags images to be refreshed on the GPU. The image editor user is still updated outside of the dependency graph. We still do not support multiple image users using a different current frame in the same image, same as 2.7. This may require adding a GPU image texture cache to keep memory usage under control. Things like rendering an animation while the viewport stays fixed at the current frame works though.
