CHANGES:

#### Changes

  + Do not break inline elements such as `{i blah}` in docstrings (ocaml-ppx/ocamlformat#1346, @jberdine)

  + Distinguish hash-getter from hash-comparison infix operators. Operators of the form `#**#` or `#**.` where `**` can be 0 or more operator chars are considered getter operators and are not surrounded by spaces, as opposed to regular infix operators (ocaml-ppx/ocamlformat#1376, @gpetiot)

  + Type constraint on return type of functions is now always printed before the function body (ocaml-ppx/ocamlformat#1381, ocaml-ppx/ocamlformat#1397, @gpetiot)

#### Bug fixes

  + Restore previous functionality for pre-post extension points (ocaml-ppx/ocamlformat#1342, @jberdine)

  + Fix extra break before `function` body of a `fun` (ocaml-ppx/ocamlformat#1343, @jberdine)

  + Fix disabling with attributes on OCaml < 4.08 (ocaml-ppx/ocamlformat#1322, @emillon)

  + Preserve unwrapped comments by not adding artificial breaks when `wrap-comments=false` and `ocp-indent-compat=true` are set to avoid interfering with ocp-indent indentation. (ocaml-ppx/ocamlformat#1352, @gpetiot)

  + Break long literal strings at the margin (ocaml-ppx/ocamlformat#1367, @gpetiot)

  + Break after a multiline argument in an argument list (ocaml-ppx/ocamlformat#1360, @gpetiot)

  + Fix placement of comments on constants (ocaml-ppx/ocamlformat#1383, @gpetiot)

  + Do not escape arguments of some Odoc tags (ocaml-ppx/ocamlformat#1391, 1408, @gpetiot, @Julow)
    The characters `[]{}` must not be escaped in the arguments of `@raise`, `@author`, `@version` and others.

  + Fix missing open line between multi-line let-binding with poly-typexpr (ocaml-ppx/ocamlformat#1372, @jberdine)

  + Remove trailing space after expression when followed by an attribute and break before attributes attached to multi-line phrases (ocaml-ppx/ocamlformat#1382, @gpetiot)

  + Do not add a space to minimal comments `(* *)`, `(** *)` and `(*$ *)` (ocaml-ppx/ocamlformat#1407, @gpetiot)

  + Fix attributes position in labelled arguments type (ocaml-ppx/ocamlformat#1434, @gpetiot)

  + Add missing parens around type annotation in anonymous function (ocaml-ppx/ocamlformat#1433, @gpetiot)

  + Fix alignment of 'then' keyword in parenthesised expression (ocaml-ppx/ocamlformat#1421, @gpetiot)

#### New features
