 hg update weekly.<i>YYYY-MM-DD</i>
 </pre>
 
+<h2 id="2011-10-06">2011-10-06</h2>
+
+<pre>
+This weekly snapshot includes changes to the io, image, and math packages that
+may require changes to client code.
+
+The io package's Copyn function has been renamed to CopyN.
+
+The math package's Fabs, Fdim, Fmax, Fmin and Fmod functions
+have been renamed to Abs, Dim, Max, Min, and Mod.
+
+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
+	image.RGBAColorModel     -> color.RGBAModel
+	image.RGBA64Color        -> color.RGBA64
+	image.RGBA64ColorModel   -> color.RGBA64Model
+(similarly for NRGBAColor, GrayColorModel, etc)
+The image.ColorImage type stays in the image package, but is renamed:
+	image.ColorImage -> 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.
+The image.Black, image.Opaque uniform images remain unchanged (although their
+type is renamed from image.ColorImage to image.Uniform).
+The corresponding color types (color.Black, color.Opaque, etc) are new.
+Nothing in the image/ycbcr is renamed yet. The ycbcr.YCbCrColor and
+ycbcr.YCbCrImage types will eventually migrate to color.YCbCr and image.YCbCr,
+at a later date.
