[@@@ocaml.deprecated ...] alert on the API module and the reimplementation of
the individual plugins using the ppxlib API.

- `Ppx_deriving.string_of_{constant,expression}_opt` to destruct
`Pconst_string` in a version-independent way
#220, #222
(Kate Deplaix, Thierry Martinez, review by Gabriel Scherer)
* Stronger type equalities in `Ppx_deriving_runtime` (for instance,
`Ppx_deriving_runtime.result` and `Result.result` are now compatible with
all OCaml versions)
#223, #225
(Thierry Martinez, review by Gabriel Scherer)
* `Ppx_deriving_runtime.Option` compatibility module
#222
(Thierry Martinez, review by Gabriel Scherer)

* Add support for OCaml 4.08.0
#193, #197, #200
(Gabriel Scherer)
4.3
---
* use Format through Ppx_deriving_runtime to avoid deprecation warning
for users of JaneStreet Base
(Stephen Bastians and Gabriel Scherer, review by whitequark)
* silence a ambiguous-field warning (41) in generated code
#163
(Étienne Millon, review by Gabriel Scherer)
* use dune
#170
(Rudi Grinberg, Jérémie Dimino)
* silence an unused-value warning for show
#179
(Nathan Rebours)

#157
(François Pottier)
4.2
---
* Add support for OCaml 4.05.0.
* Use the `ocaml-migrate-parsetree` library to support multiple
versions of OCaml.
* Fix comparison order of fields in records (#136).
* Silence an `unused rec flag` warning in generated code (#137).
* Monomorphize comparison function for builtin types (#115)
* Raise an error when `type nonrec` is encountered (#116).
* Display an error message when dynamic package loading fails.
* Add a `with_path` option to `@@deriving` to skip the module path
in generated code (#120).
The homepage for the project has now moved to:

4.1
---
* Fix type error with inheritied polymorphic variant type in
[@@deriving map].
* Fix incorrect handling of multi-argument constructors in
[@@deriving show].
* Add API hooks for ppx_type_conv.
4.0
---
* Show, eq, ord, map, iter, fold: add support for `Result.result`.
* Ppx_deriving.Arg: use Result.result instead of polymorphic variants.
* Ppx_deriving.sanitize: parameterize over an opened module.
* Add support for `[@@deriving]` in module type declarations.
* 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
* Fix prefixed attribute names (`[@deriving.foo.attr]` and `[@foo.attr]`).
* Add allow_std_type_shadowing option for eq and show.
2.0
---
* Add support for open types.
1.1

* New plugin: create.
* Show, eq, ord: handle `_`.
* Show, eq, ord, map, iter, fold: handle inheriting from a parametric
polymorphic variant type.
* Make `Ppx_deriving.poly_{fun,arrow}_of_type_decl` construct functions

more than one parameter.
* Add `Ppx_deriving.fold_{left,right}_type_decl`.
1.0

* Make deriver names lowercase.
* Remove Findlib+dynlink integration. All derivers must now be
explicitly required.
* Allow shortening [%derive.x:] to [%x:] when deriver x exists.
* Make `Ppx_deriving.core_type` field optional to allow ignoring
unsupported [%x:] shorthands.
* Add support for [@@deriving foo { optional = true }] that does
not error out if foo is missing, useful for optional dependencies.
* Rename ~name and ~prefix of `Ppx_deriving.attr` and
`Ppx_deriving.Arg.payload` to `~deriver`.
* Renamed `Ppx_deriving.Arg.payload` to `get_attr`.
* Add `Ppx_deriving.Arg.get_expr` and `get_flag`.
