+This release includes a language change that restricts the use of goto.
+In essence, a "goto" statement outside a block cannot jump to a label inside
+that block. Your code may require changes if it uses goto.
+This changeset shows how the new rule affected the Go tree:
+	http://code.google.com/p/go/source/detail?r=dc6d3cf9279d
+
+The os.ErrorString type has been hidden. If your code uses os.ErrorString it
+must be changed. Most uses of os.ErrorString can be replaced with os.NewError.
+
+Other changes:
+* 5c: do not use R9 and R10.
+* 8l: more fixes for Plan 9 (thanks Lucio De Re).
