Changes in version 0.3.0                        

  - Improved messages for non-working rules (#1) Thanks to Marlou van de
    Sande

  - Fix for statements using %in% (bug #2), this was due to validate
    which replaced it with %vin%. Thanks to Marlou van de Sande for
    reporting.

  - Tables in a schema were not working (bug issue #3), is now fixed.

  - Added restriction R >= 4.0. Thanks to @Wytzepakito, #6
