[new release] ppxlib (0.32.0)

CHANGES:

- Add an optional `embed_errors` argument to `Context_free.map_top_down` that
  controls how to deal with exceptions thrown by context-free rules.
  (ocaml-ppx/ppxlib#468, @NathanReb)

- Fix `Longident.parse` so it properly handles unparenthesized dotted operators
  such as `+.` or `*.`. (ocaml-ppx/ppxlib#111, @rgrinberg, @NathanReb)

- raising an exception does no longer cancel the whole context free phase(ocaml-ppx/ppxlib#453, @Burnleydev1)

- Sort embedded errors that are appended to the AST by location so the compiler
  reports the one closer to the beginning of the file first. (ocaml-ppx/ppxlib#463, @NathanReb)

- Update `Attribute.get` to ignore `loc_ghost`. (ocaml-ppx/ppxlib#460, @ceastlund)

- Add API to manipulate attributes that are used as flags (ocaml-ppx/ppxlib#408, @dianaoigo)

- Update changelog to use ISO 8061 date format: YYYY-MM-DD. (ocaml-ppx/ppxlib#445, @ceastlund)

- Replace `Caml` with `Stdlib`. (ocaml-ppx/ppxlib#427, @ceastlund)

- When a transformation raises, the last valid AST is used as input to the upcoming
  transformations. All such errors are collected and appended as
  extension nodes to the final AST (ocaml-ppx/ppxlib#447, @Burnleydev1)

- Fix a small mistake in the man pages: Embededding errors is done by default with
  `-as-pp`, not with `-dump-ast` (ocaml-ppx/ppxlib#464, @pitag-ha)

- Set appropriate binary mode when writing to `stdout` especially for Windows
  compatibility. (ocaml-ppx/ppxlib#466, @jonahbeckford)

+synopsis: "Standard infrastructure for ppx rewriters"
+description: """
+Ppxlib is the standard infrastructure for ppx rewriters
+and other programs that manipulate the in-memory representation of
+OCaml programs, a.k.a the "Parsetree".
+
+It also comes bundled with two ppx rewriters that are commonly used to
+write tools that manipulate and/or generate Parsetree values;
+`ppxlib.metaquot` which allows to construct Parsetree values using the
+OCaml syntax directly and `ppxlib.traverse` which provides various
+ways of automatically traversing values of a given type, in particular
+allowing to inject a complex structured value into generated code.
