CLI

Bug fixes

• Fix #3069, prevent overwriting paths when using --staged or --changed options. Contributed by @unvalley
• Fix a case where the file link inside a diagnostic wasn't correctly displayed inside a terminal run by VSCode. Contributed by @uncenter

Configuration

Bug fixes

• Fix #3067, by assigning the correct default value to indentWidth. Contributed by @ematipico

Formatter

Bug fixes

• Fix the bug where whitespace after the & character in CSS nesting was incorrectly trimmed, ensuring proper targeting of child classes #3061. Contributed by @denbezrukov
• Fix #3068 where the CSS formatter was inadvertently converting variable declarations and function calls to lowercase. Contributed by @denbezrukov
• Fix the formatting of CSS grid layout properties. Contributed by @denbezrukov

Linter

Bug fixes

• The noEmptyBlock css lint rule now treats empty blocks containing comments as valid ones. Contributed by @Sec-ant

• useLiteralKeys no longer reports quoted member names (#3085).

  Previously useLiteralKeys reported quoted member names that can be unquoted. For example, the rule suggested the following fix:

  - const x = { "prop": 0 };
  + const x = { prop: 0 };
  

  This conflicted with the option quoteProperties of our formatter.

  The rule now ignores quoted member names.

• noEmptyInterface now ignores empty interfaces in ambient modules (#3110). Contributed by @Conaclos

• noUnusedVariables and noUnusedFunctionParameters no longer report the parameters of a constructor type (#3135).

  Previously, arg was reported as unused in a constructor type like:

  export type Classlike = new (arg: unknown) => string;
  

  Contributed by @Conaclos

• noStringCaseMismatch now ignores escape sequences (#3134).

  The following code is no longer reported by the rule:

  s.toUpperCase() === "\u001b";
  

  Contributed by @Conaclos

Parser

New features

• Implemented CSS Unknown At-Rule parsing, allowing the parser to gracefully handle unsupported or unrecognized CSS at-rules. Contributed by @denbezrukov

Bug fixes

• Fix #3055 CSS: Layout using named grid lines is now correctly parsed. Contributed by @denbezrukov
• Fix #3091. Allows the parser to handle nested style rules and at-rules properly, enhancing the parser's compatibility with the CSS Nesting Module. Contributed by @denbezrukov
