+
+<pre>
+This release includes changes to the http package and a small language change.
+Your code will require changes if it manipulates http Headers or omits the
+condition in if statements.
+
+The new http.Header type replaces map[string]string in the Header and Trailer
+fields of http.Request and http.Response.
+A Header value can be manipulated via its Get, Set, Add, and Del methods.
+See http://golang.org/pkg/http/#Header
+
+The condition is now mandatory in if statements.
+Previously it would default to true, as in switch and for statements.
+This code is now illegal:
+	if x := foo(); {
+		// code that is always executed
+	}
+The same effect can be achieved like this:
+	if x := foo(); true {
+		// code
+	}
+Or, in a simpler form:
+	{
+		x := foo()
+		// code
+	}
