hg update weekly.<i>YYYY-MM-DD</i>
+This weekly snapshot includes changes to the image, path/filepath, and time
+packages. Code that uses these packages may need to be updated.
+The image package's NewX functions (NewRGBA, NewNRGBA, etc) have been changed
+to take a Rectangle argument instead of a width and height.
+Gofix can make these changes automatically.
+The path/filepath package's Walk function has been changed to take a WalkFunc
+function value instead of a Visitor interface value. WalkFunc is like the
+Visitor's VisitDir and VisitFile methods except it handles both files and
+ func(path string, info *os.FileInfo, err os.Error) os.Error
+To skip walking a directory (like returning false from VisitDir) the WalkFunc
+The time package's Time struct's Weekday field has been changed to a method.
+The value is calculated on demand, avoiding the need to re-parse
+programmatically-constructed Time values to find the correct weekday.
+There are no gofixes for the filepath or time API changes, but instances of the
+old APIs will be caught by the compiler. The Weekday one is easy to update by
+hand. The Walk one may take more consideration, but will have fewer instances
