+This release includes changes to the strconv, http, and exp/draw packages.
+Client code that uses the http or exp/draw packages will need to be changed,
+and code that uses strconv or fmt's "%q" formatting directive merits checking.
+
+The strconv package's Quote function now escapes only those Unicode code points
+not classified as printable by unicode.IsPrint. Previously Quote would escape
+all non-ASCII characters. This also affects the fmt package's "%q" formatting
+directive. The previous quoting behavior is still available via strconv's new
+QuoteToASCII function.   
+
+Most instances of the type map[string][]string in the http package have been
+replaced with the new Values type. The http.Values type has the Get, Set, Add,
+and Del helper methods to make working with query parameters and form values
+more convenient.
+
+The exp/draw package has been split into the image/draw and exp/gui packages.
+
+Other changes:
