This release introduces a helper class and annotation to map configurations done in annotations to initialization commands for related classes.
One example:
I have created the FluApiGen project some time ago - a processor that helps to generate fluent api code.
The API allows to apply validators on method parameters by using annotations (i.e. for matching String based method parameter with regular expression).
The new helper class will generate the command needed to instantiate the annotation related implementations, which then can be included in the generated code.
Biggest benefit is that the annotation attribute values will be hardcoded in that initialization command - so the generated code will even work without the annotations present at runtime.
