+<pre>
+This release contains many fixes and improvements, including several
+clarifications and consolidations to the Language Specification.
+
+The type checking rules around assignments and conversions are simpler but more
+restrictive: assignments no longer convert implicitly from *[10]int to []int
+(write x[0:] instead of &x), and conversions can no longer change the names of
+types inside composite types.
+
+The fmt package now includes flexible type-driven (fmt.Scan) and 
+format-driven (fmt.Scanf) scanners for all basic types.
+
+* big: bug fix for Quo aliasing problem.
+* bufio: change ReadSlice to match description.
+* cgo: bug fixes.
+* doc: add Google I/O talk and programs,
+        codereview + Mercurial Queues info (thanks Peter Williams).
+* exp/draw: Draw fast paths for the Over operator,
+        add Rectangle.Eq and Point.In, fix Rectangle.Clip (thanks Roger Peppe).
+* fmt: Scan fixes and improvements.
+* gc: backslash newline is not a legal escape sequence in strings,
+        better error message when ~ operator is found,
+        fix export of complex types,
+        new typechecking rules.
+* go/parser: correct position of empty statement ';'.
+* gofmt: fix test script.
+* goinstall: use 'git pull' instead of 'git checkout' (thanks Michael Hoisie).
+* http: add Head function for making HTTP HEAD requests,
+        handle status 304 correctly.
+* image: add Opaque method to the image types.
+        make Color.RGBA return 16 bit color instead of 32 bit color.
