The package has been split into 3 libraries: jazzy-core.jar, jazzy-swing.jar, and jazzy-examples.jar. This allows you more precise control over how the library is used. The DoubleMetaphone class has been updated to make it more speed efficient. Other areas of the API were also changed for performance. A new extensible configuration mechanism has been added. Now, the default behavior is to use properties files for all aspects of program configuration. The mechanism is extensible, so you can modify it to your own particular configuration needs.
The speed of the DoubleMeta algorithm was improved, as was the speed of loading the dictionary. All String arrays are now final. An ant build file was added. The packaging was changed slightly. The classes SpellChecker, SpellCheckListener and SpellCheckEvent were added, and FastHashMap was removed in favour of java.util.HashMap.
