1.18.0

CHANGES:

Features

• Introduce a configuration option to control dune diagnostics. The option is
  called duneDiganostics and it may be set to { enable: false } to disable
  diagnostics. (#1221)

• Support folding of ifthenelse expressions (#1031)

• Improve hover behavior (#1245)

  Hovers are no longer displaye on useless parsetree nodes such as keywords,
  comments, etc.

  Multiline hovers are now filtered away.

  Display expanded ppx's in the hover window.

• Improve document symbols (#1247)

  Use the parse tree instead of the typed tree. This means that document
  symbols will work even if the source code doesn't type check.

  Include symbols at arbitrary depth.

  Differentiate functions / types / variants / etc.

  This now includes PPXs like let%expect_test or let%bench in the outline.

• Introduce a destruct-line code action. This is an improved version of the
  old destruct code action. (#1283)

• Improve signature inference to only include types for elements that were
  absent from the signature. Previously, all signature items would always be
  inserted. (#1289)

• Add an update-signature code action to update the types of elements that
  were already present in the signature (#1289)

• Add custom
  ocamllsp/merlinCallCompatible
  request (#1265)

• Add custom ocamllsp/typeEnclosing request (#1304)

Fixes

• Detect document kind by looking at merlin's suffixes config.

  This enables more lsp features for non-.ml/.mli files. Though it still
  depends on merlin's support. (#1237)

• Correctly accept the --clientProcessId flag. (#1242)

• Disable automatic completion and signature help inside comments (#1246)

• Includes a new optional/configurable option to toggle syntax documentation. If
  toggled on, allows display of syntax documentation on hover tooltips. Can be
  controlled via environment variables and by GUI for VS code. (#1218)

• For completions on labels that the LSP gets from merlin, take into account
  whether the prefix being completed starts with ~ or ?. Change the label
  completions that start with ? to start with ~ when the prefix being
  completed starts with ~. (#1277)

• Fix document syncing (#1278, #1280, fixes #1207)

• Stop generating inlay hints on generated code (#1290)

• Fix parenthesizing of function types in SignatureHelp (#1296)

• Fix syntax documentation rendering (#1318)

1.17.0

CHANGES:

Fixes

• Fix missing super & subscripts in markdown documentation. (#1170)

• Do not invoke dune at all if --fallback-read-dot-merlin flag is on. (#1173)

• Fix semantic highlighting of infix operators that contain '.'. (#1186)

• Disable highlighting unit as an enum member to fix comment highlighting bug. (#1185)

• Improve type-on-hover and type-annotate efficiency by only formatting the type
  of the first enclosing. (#1191, #1196)

• Fix the encoding of URI's to match how vscode does it (#1197)

• Fix parsing of completion prefixes (#1181)

Features

• Compatibility with Odoc 2.3.0, with support for the introduced syntax: tables,
  and "codeblock output" (#1184)

• Display text of references in doc strings (#1166)

• Add mark/remove unused actions for open, types, for loop indexes, modules,
  match cases, rec, and constructors (#1141)

• Offer auto-completion for the keyword in (#1217)

1.16.2

CHANGES:

Fixes

• Fix file permissions used when specifying output files of pp and ppx. (#1153)

1.16.1

CHANGES:

Fixes

• Support building with OCaml 5.0 and 5.1 (#1150)

1.16.0-4.14

CHANGES:

Fixes

• Disable code lens by default. The support can be re-enabled by explicitly
  setting it in the configuration. (#1134)

• Fix initilization of ocamlformat-rpc in some edge cases when ocamlformat is
  initialized concurrently (#1132)

• Kill unnecessary $ dune ocaml-merlin with SIGTERM rather than SIGKILL
  (#1124)

• Refactor comment parsing to use odoc-parser and cmarkit instead of
  octavius and omd (#1088)

  This allows users who migrated to omd 2.X to install ocaml-lsp-server in the
  same opam switch.

  We also slightly improved markdown generation support and fixed a couple in
  the generation of inline heading and module types.

• Allow opening documents that were already open. This is a workaround for
  neovim's lsp client (#1067)

• Disable type annotation for functions (#1054)

• Respect codeActionLiteralSupport capability (#1046)

• Fix a document syncing issue when utf-16 is the position encoding (#1004)

• Disable "Type-annotate" action for code that is already annotated.
  (#1037), fixes
  #1036

• Fix semantic highlighting of long identifiers when using preprocessors
  (#1049, fixes
  #1034)

• Fix the type of DocumentSelector in cram document registration (#1068)

• Accept the --clientProcessId command line argument. (#1074)

• Accept --port as a synonym for --socket. (#1075)

• Fix connecting to dune rpc on Windows. (#1080)

Features

• Add "Remove type annotation" code action. (#1039)

• Support settings through didChangeConfiguration notification (#1103)

• Add "Extract local" and "Extract function" code actions. (#870)

• Depend directly on merlin-lib 4.9 (#1070)

1.15.1-5.0

CHANGES:

Fixes

• Fix race condition when a document was being edited and dune in watch mode was
  running (#1005, fixes
  #941,
  #1003)

1.15.0-5.0

CHANGES:

Features

• Add support for OCaml 5.0

• Enable semantic highlighting
  support by default (#933)

• Support connecting over pipes and socket. Pipes on Windows aren't yet
  supported (#946)

  More
  about communication channels in LSP specification.

• Re-enable ocamlformat-rpc for formatting code snippets (but not files and
  not on Windows) (#920, #939)

  One needs to have installed either ocamlformat package version > 0.21.0 or,
  otherwise, ocamlformat-rpc package. Note that previously ocamlformat-rpc
  came in a standalone OPAM package, but since ocamlformat version > 0.21.0,
  it comes within ocamlformat package.

• Add custom
  ocamllsp/hoverExtended
  request (#561)

• Support utf-8 position encoding clients (#919)

  More about position encoding in LSP specification.

• Show unwrapped module alias types on hovering over module names. This is due
  to upgrading to merlin 4.7 and using merlin's verbosity=smart by default
  (#942)

Fixes

• Respect the client's completion item resolve and preSelect capabilities
  (#925, #936)

• Disable polling for dune's watch mode on Windows and OCaml 4.14.0 (#935)

• Fix semantic highlighting of "long identifiers," e.g., Foo.Bar.x (#932)

• Fix syncing of document contents:

  • For ranges that span an entire line (#927)
  • Previously, whole line edits would incorrectly eat the newline characters (#971)
