Incremental obfuscation is used when you need to create a patch or add-on to your application. In such case you need the guarantee that new names of classes, methods and fields are consistent with the previously obfuscated version.

Using the log file generated during the previous run of Allatori as input when obfuscating the next release, makes the two fully compatible. So a patch or add-on can be seamlessly integrated to the previously deployed application.
