• Add support for loading findlib packages instead of just files in ppx_deriving_main.

• Treat types explicitly qualified with Pervasives also as builtin.

• Compatibility with statically linked ppx drivers.

3.1

• Show, eq, ord: hygienically invoke functions from referenced modules (such as X.pp for X.t when deriving show) to coexist with modules shadowing ones from standard library.

• Iter, map, fold: hygienically invoke List and Array functions.

3.0

• Implement hygiene: Ppx_deriving.{create_quoter,quote,sanitize,with_quoter}.

• Show, eq, ord: add support for lazy_t.

• Add support for [@nobuiltin] attribute.

• Add Ppx_deriving.hash_variant.

• Remove allow_std_type_shadowing option.

• Remove Ppx_deriving.extract_typename_of_type_group.

2.1

• Fix breakage occurring with 4.02.2 w.r.t record labels

• Add allow_std_type_shadowing option for eq and show.

2.0

• Add support for open types.

1.1

• Show, eq, ord: handle _.

• Show, eq, ord, map, iter, fold: handle inheriting from a parametric polymorphic variant type.

• Remove Findlib+dynlink integration. All derivers must now be explicitly required.
