• Range: Fix ranged formatting not using the correct line width (#​6050 by @​mathieulj)

  // Input
  function f() {
    if (true) {
      call("this line is 79 chars", "long", "it should", "stay as single line");
    }
  }
  
  // Output (Prettier stable run with --range-start 30 --range-end 110)
  function f() {
    if (true) {
      call(
        "this line is 79 chars",
        "long",
        "it should",
        "stay as single line"
      );
    }
  }
  
  // Output (Prettier stable run without range)
  function f() {
    if (true) {
      call("this line is 79 chars", "long", "it should", "stay as single line");
    }
  }
  
  // Output (Prettier master with and without range)
  function f() {
    if (true) {
      call("this line is 79 chars", "long", "it should", "stay as single line");
    }

• JavaScript: Fix closure compiler typecasts ([#​5947] by @​jridgewell)

  If a closing parenthesis follows after a typecast in an inner expression, the typecast would wrap everything to the that following parenthesis.

  // Input
  test(/** @​type {!Array} */(arrOrString).length);
  test(/** @​type {!Array} */((arrOrString)).length + 1);
  
  // Output (Prettier stable)
  test(/** @​type {!Array} */ (arrOrString.length));
  test(/** @​type {!Array} */ (arrOrString.length + 1));
  
  // Output (Prettier master)
  test(/** @​type {!Array} */ (arrOrString).length);
  test(/** @​type {!Array} */ (arrOrString).length + 1);

• JavaScript: respect parenthesis around optional chaining before await (#​6087 by @​evilebottnawi)

  // Input
  async function myFunction() {
    var x = (await foo.bar.blah)?.hi;
  }
  
  // Output (Prettier stable)
  async function myFunction() {
    var x = await foo.bar.blah?.hi;
  }
  
  // Output (Prettier master)
  async function myFunction() {
    var x = (await foo.bar.blah)?.hi;
  }

• Handlebars: Fix {{else}}{{#if}} into {{else if}} merging (#​6080 by @​dcyriller)

  // Output (Prettier stable)
  {{#if a}}
    a
  {{else if c}}
    c
  e
  {{/if}}
  
  // Output (Prettier master)
  Code Sample

• JavaScript: Improved multiline closure compiler typecast comment detection (#​6070 by @​yangsu)

  Previously, multiline closure compiler typecast comments with lines that
  start with * weren't flagged correctly and the subsequent parenthesis were
  stripped. Prettier master fixes this issue.

  // Input
  const style =/**
   * @​type {{
   *   width: number,
   * }}
  */({
    width,
  });
  
  // Output (Prettier stable)
  const style =/**
   * @​type {{
   *   width: number,
   * }}
  */ {
    width,
  };
  
  // Output (Prettier master)
  const style =/**
   * @​type {{
   *   width: number,
   * }}
  */({
    width,
  });
