 - Added `std/enumutils` module. Added `genEnumCaseStmt` macro that generates case statement to parse string to enum.
   Added `items` for enums with holes.
+  Added `symbolName` to return the enum symbol name ignoring the human readable name.
 
-- Added `typetraits.SomeEnumWithHoles` for enums with holes.
+- Added `typetraits.HoleyEnum` for enums with holes, `OrdinalEnum` for enums without holes.
 
 - Removed deprecated `iup` module from stdlib, it has already moved to
   [nimble](https://github.com/nim-lang/iup).
