 ## Improvements
 
-* [x] define the sequence of redacted fields in a private variable
-  * [x] move aforementioned variable in the case class companion object

-* [x] split into three artifacts (lib, compiler plugin and tests)
-  * [x] find a better alternative instead of using `managedSources`
-* [x] refactor codebase
 * [ ] create Sbt plugin
-* [ ] publish library and compiler plugin to maven
 * [ ] add some benchmarks with jmh
