A minor release of shapeless mainly focussed on replacing arity-specific boilerplate with SBT based code generation.
-
The boilerplate for HList <-> Tuple conversion type class instances is now generated and covers all arities.
-
The boilerplate for ordinary function <-> HList function conversion type class instances is now generated and covers all arities.
-
The boilerplate for tuple Typeable type class instances is now generated and covers all arities.
-
Nat types and values are now generated.
-
There is now a type- and value-level conversion from Nats to Int, and there has been some minor reorganization of the Nat type classes.
