1.7.3

• #952 Mutate map return to emptyMap instead of null
• #954 Allow mutators to be excluded
• #957 Filter equivalent mutations to Boolean.TRUE and Boolean.FALSE

#954 allows mutators to be excluded by prepending a - to their name when specifying the mutator set. e.g -TRUE_RETURNS

1.7.2

• #943 Change default mutators - replace negate conditional with remove conditional
• #946 Mutate stream returns to empty stream instead of null

1.7.1

• #932 Improve switch mutation descriptions
• #934 Configure console output verbosity
• #940 Hide internal features
• #942 Fix for 3rd party mutation operators not added to client classpath
• #939 Improve caching of bytecode retrieval

1.7.0

#923 Internal interface changes
#930 Pluggable mutators

Due to internal changes some third party plugins maybe incompatible with this release.

All history files should be deleted before upgrading.

The names of the remove conditionals mutators have changed slightly as a result of #930 and may need to be updated in build scripts if explicitly activated.

1.6.9

• #922 Filter equivalent stream.empty mutants in flatMap calls
• #921 Guarantee order of mutation operators
• #919 Filter junk mutations in java records

1.6.8

• #917 - Add method to retrieve all mutator ids for pitclipse and other tooling
• #913 - Bump ASM to 9.2

1.6.7

#897 Fix description when replacing value with empty set
#900 Support multiple test engines
#822 Fix regression of NPE when reading classpath manifest
#798 Fix regression of jvmArgs parameter support via maven
#797 Fix regression of line coverage on console

As a result of #900 the testPlugin parameter is now defunct, but pitest will continue to accept it without error for this release. Pitest will use any test-engines supplied on the classpath, falling back to the built in JUnit4 support when other test engines cannot handle the class.

1.6.6

#891 - Fix history performance
#889 - Do not scan classpath for history when option not supplied
#887 - Fix css for timeouts and memory errors
