1.9.5

• Fix automatic closing of files without an extension (#887)

1.9.4

• Restore compatibility with opam 2.0.x (#884)

1.9.3

• Fix dune subdir stanza syntax highlighting (#870)

1.9.2

• Improve dune variable syntax highlighting. Add highlighting for env and
  bin-available variables. (#872)

1.9.1

• Make the check for out of date ocamllsp more conservative. It will no longer
  alert the user unless the extension is certain an upgrade is possible (#859)

1.9.0

• Dune syntax highlighting fix (#742)

  The syntax for dune files has been re-written from scratch for a more correct
  implementation. Every dune stanza documented by Dune is now supported, and
  only the correct fields in each stanza are recognized.

• Fix the detection of opam's root directory when no switch is detected (#831)

• Add support for opening compilation artifacts in human-readable form in the
  editor (#798)

  Currently supported artifacts include .cmi, .cmt(i), .cmo, .cma,
  .cmx(a/s), and .bc files.

  To learn more about these files, see: https://ocaml.org/manual/comp.html

• Warn if the extension sees not the latest OCaml-LSP version compatible with
  the OCaml distribution installed in the current sandbox.

• Highlighted the UNREACHABLE element in cram .t files (#754)

• Activate extension on cram files, or when the workspace contains
  dune-workspace or dune files. (#750)

• Add commands Jump to Next Typed Hole (shortcut: Alt + L) and
  Jump to Previous Typed Hole (shortcut: Alt + Shift + L)

  What typed holes are

  Merlin has a concept of "typed holes" that are syntactically represented as
  _. Files that incorporate typed holes are not considered valid OCaml, but
  Merlin and OCaml-LSP support them. One example when such typed holes can occur
  is when one "destructs" a value, e.g., destructing (Some 1) will generate
  code match Some 1 with Some _ -> _ | None -> _. While the first underscore
  is a valid "match-all"/wildcard pattern, the rest of underscores are typed
  holes that one needs to replace with valid OCaml code. These new commands help
  to navigate easily from one hole to another (#643)

• Rename the extension's section in VS Code Settings from OCaml configuration
  to OCaml Platform (#674)

• Add ocaml.server.extraEnv configuration option to pass extra environment
  variables to the language server, i.e., OCaml-LSP (#674)

• Parsetree exploration and development tools. It is now possible to explore the
  structure of the parsetree in a custom editor. Additionally, it is possible to
  view preprocessed source of any OCaml source file (when applicable). Full
  functionality is available only for dune projects. (#666)

• Add commands Show OCaml Language Server Output,
  Show OCaml Platform Extension Output, and Show OCaml Commands Output.
  (#745)

• Fix highlighting of escaped odoc source code braces (#690)

• opam exec is now called with --set-switch flag; this is useful when we
  launch a terminal within a certain sandbox set in the extension (#744, fixes
  #655)

• The currently active OPAM switch in the workspace folder (project root) is
  shown first in the list of sandboxes when selecting a sandbox. (#751)

• Show a different icon for the currently active OPAM switch in the "OPAM
  Switches" tree view (#751)

v1.8.4

• Fix inclusion of files in extension package

v1.8.3

• Fix showing error message if ocaml-lsp is missing (#586)

v1.8.2

• Fix switching between implementation/interface (#561)

• Stop automatically highlighting suffixed META files (#565)

v1.8.1

• Revert automatic installation of platform tools

  The feature is not flexible enough and caused issues with multiple users. We
  will work on making it more flexible and fit more workflows before releasing
  it.
