-  Version 1.3 work in progress.
+  Version 1.3 released.
 
-  primesum now supports 256-bit results by default! So now there is
-  only one primesum version for both 128-bit and 256-bit results.
-  This version has been optimized so that it uses 128-bit arithmetic
-  for numbers < 2^63 and 256-bit arithmetic for numbers >= 2^63.
+  This version runs up to 20% faster and uses only half as much
+  memory as primesum-1.2. primesum now also supports 256-bit
+  results by default! So now there is only one primesum version for
+  both 128-bit and 256-bit results.
 
   * S2_hard.cpp: Get rid of binary indexed tree.
   * P2.cpp: Optimize 128-bit and 256-bit arithmetic.
