 ## Changelog
 
 - Add user-defined literals `_ic`, `_uc` and `_sc` to represent integral constants.
 
-- Add "hybrid" functors for basic math operations with integral constant arguments, i.e., `Hybrid::max`, `Hybrid::min`, `Hybrid::plus`, `Hybrid::minus`, and `Hybrid::equals`. Operations between two integral constants result in an integral constant, whereas operations with at least one non integral constant argument is performed on the underlying value type.

 - Add utility `CopyableOptional` that allows to wrap types that are copy constructible but not
   copy assignable and provide assignment operations based on the constructors.
 
-- Added the methods `checkThrow`,`requireThrow` and the corresponding `checkNoThrow`,`requireNoThrow` to the `Dune::TestSuite` to test for throwing and no throwing of exceptions.
