Parts of the image package have been moved to the new image/color package.
The spin-off renames some types. The new names are simply better:
image.Color -> color.Color
image.ColorModel -> color.Model
image.ColorModelFunc -> color.ModelFunc
image.PalettedColorModel -> color.Palette
image.RGBAColor -> color.RGBA

The image.ColorImage type stays in the image package, but is renamed:
image.ColorImage -> image.Uniform
image.ColorImage -&gt; image.Uniform
The image.Image implementations (image.RGBA, image.RGBA64, image.NRGBA,
image.Alpha, etc) do not change their name, and gain a nice symmetry:
an image.RGBA is an image of color.RGBA, etc.

There is one language change: the ability to convert a string to []byte or

You can convert your existing sources using these gofmt commands:
gofmt -r 'strings.Bytes(x) -> []byte(x)' -w file-or-directory-list
gofmt -r 'strings.Runes(x) -> []int(x)' -w file-or-directory-list
