+<pre>
+This release removes the float and complex types from the language.
+
+The default type for a floating point literal is now float64, and
+the default type for a complex literal is now complex128.
+
+Existing code that uses float or complex must be rewritten to
+use explicitly sized types.
+
+The two-argument constructor cmplx is now spelled complex.
