Known issues

• cmake --install with --component build-tools does not install the build
  tools. Fix: Git commit
  3923f0df76d24b73d57f15eec61ab190ea048093

Added

• 2 ^ 8 now reports E0710 ("'^' is the XOR operator; to exponentiate, use
  '**' instead"). (Implemented by pedrobl1718.)
• A missing } in a function parameter list now reports E0161 ("unclosed
  object literal; expected '}'"). (Implemented by Yash Masani.)
• quick-lint-js now builds on Alpine Linux and other musl-based distributions.
• TypeScript support (still experimental):
  • Invalid recursive type definitions such as type T = T; now report
    E0384 ("cannot use type directly in its own definition").
  • quick-lint-js now recognizes import types.
  • quick-lint-js now recognizes .d.ts files:
    • CLI: --language=experimental-typescript-definition
    • LSP server: typescriptdefinition; typescript will detect from the URI,
      and typescriptsource prevents detection from the URI
    • Visual Studio Code extension: detected from the file name

Fixed

• LSP: On macOS, quick-lint-js no longer hangs if a file has too many
  diagnostics.
• #property in object expressions are now parsed correctly and do not report
  E0155.
• ({k = defaultValue} = o); no longer incorrectly reports E0253 ("use ':'
  instead of '=' in object literals").
• Class property initializers no longer incorrectly report E0058 ("variable
  used before declaration"). Example:
  class C { myProperty = f(); } const f = () => {};
• TypeScript support (still experimental):
  • quick-lint-js no longer falsely reports E0058 ("variable used before
    declaration") for code such as function f<T extends T[]>() {}.
  • Declaring a type alias or an interface inside a declare namespace no
    longer reports E0357 ("'declare namespace' cannot contain statements,
    only declarations").
  • const enum E {} no longer causes E0150.
  • Using a declare-ed variable prior to its declaration is now allowed.
    Example: new C(); declare class C { }
  • Using a variable in a declare class's extends clause prior to the
    variable's declaration is now allowed.
    Example: declare class Derived extends Base { } class Base { }
  • VS Code: The extension now loads when only opening a TypeScript file.
    (Previously, the extension would only load when you opened a JavaScript or
    JSON file.) The quick-lint-js.experimental-typescript setting is still
    required.
  • Vim ALE: JSX syntax is now recognized inside .tsx files.

Changed

• quick-lint-js no longer depends on the Boost third-party library. The
  QUICK_LINT_JS_USE_BUNDLED_BOOST CMake variable now has no effect.
