#433 - Aggregate reports via maven (thanks @rchargel)
#438 - Filter tests at method level (thanks @ftrautsch)
#439 - Primitives return mutator doesn't handle bytes
#380 - Remove reliance on xstream for improved java 9 support
#414 - Replace xstream history store (thanks @kiftio)
Note when upgrading that history files generated by previous releases are not compatible with 1.3.2 and above.
The removal of xstream eliminates all access warnings under java 9. If running from the commandline or ant commons-codec is now required on the tool classpath.
