 ## 0.4.5
 
-* The file fwdpp/internal/gamete_lookup_table.hpp was removed and the library updated to stop using this method to check for gamete uniqueness.  The result is a 20% reduction in run times and a slight reduction in peak memory use.  This change was enabled by the changes introduced in 0.4.4, and comes with no change in output.
+* Issues #31 and #32 fixed
