+<p>We have changed the way that the Type Legalizer legalizes vectors.
+	The type legalizer now attempts to promote integer elements.
+	This enabled the implementation of vector-select.
+	Additionally, we see a performance boost on workloads which use vectors of chars and shorts, since they are now promoted
+	to 32-bit types, which are better supported by the SIMD instruction set.
+	Floating point types are still widened as before.</p>

 <p>We have put a significant amount of work into the code generator
    infrastructure, which allows us to implement more aggressive algorithms and
    make it run faster:</p>
