• Improve unused import diagnostics
• Fix the disableElmLSDiagnostics setting not working
• Don't crash if server fails to initialize
• Fix wrong display of fix record diff
• Handle kernel code usages better
• More type checker improvements

• Fixed test files not being recognized correctly on windows
• Fixed some type inference problems
• Fixed linked editing ranges breaking, when deleting a whole word
• Remove file entry from symbolproviders (Outline, Go to symbol and breadcrumbs)
• Don't show files from dependencies in WorkspaceSymbolProvider (Go to symbol in workspace)

Features

• Enabled type checking diagnostics that update on document change. These include parsing errors, type mismatch errors, value not found errors, etc

• Support file events APIs (Previously VSCode only)

  • On file create, the module name will be inserted
  • On file rename, the module name and all references will be updated

• A new "extract function" code action. Select a complete expression and it can be extracted to a function in the top level or the enclosing let expression (if there is one)

• A new "install package" code action. When you try to import a module that is not installed, a code action will offer to install it. (we only check your local elm cache for possible packages and there is a setting to control skipping confirmation)

• Replaced elm-analyse with our own diagnostics, there might be missing rules for you due to this

• Show inferred type information on hovers

• Support linked editing ranges. When editing a function name, the type annotation name will auto rename, or vice versa (needs to be enabled in most clients)

• Watch elm.json for changes. The server will restart when a change is detected

• Run elm make on server init

• Improve record completions

• Ports now have codeLenses, can find references and have correct types on mouseover

Bug Fixes

• Greatly improve performance of diagnostics and type inference
• Fix some type inference cases
• Fix module resolution to be more like how the compiler resolves modules

• Fix how errors from third party binaries are shown
• Fixed test dependencies being available in non test modules

Other Changes

• Support finding field references and renaming
• Tree sitter parser improvements
• Handle negate expressions in type inference
