Biome CLI v2.5.9

2.5.9

Patch Changes

• #11321 41386f3 Thanks @​dyc3! - Fixed #11315: The CSS parser now recovers at declaration boundaries after bogus declarations, allowing subsequent valid declarations to be parsed.

• #11248 57b197e Thanks @​yanthomasdev! - Expanded the environment variable metadata used by biome rage to include BIOME_BINARY, BIOME_LOG_FILE, and RUST_BACKTRACE as well as reworded explanations for better readability.

• #11377 a8798ea Thanks @​Netail! - Added a new nursery rule useNamedLayer which disallows anonymous cascade layers.

  @layer {
    a {
      color: red;
    }
  }

• #11327 6771cf5 Thanks @​dyc3! - The HTML formatter now preserves meaningful blank lines in HTML, including spacing after elements with trailing spaces and blank lines between comment groups.

   <div>
     <!-- first group -->
  +
     <!-- second group -->
   </div>

• #10312 ba8aa18 Thanks @​dyc3! - Added the nursery rule useTailwindShorthandClasses, which suggests shorter Tailwind utility classes. For example, the rule suggests replacing w-4 h-4 with size-4.

• #11333 715e0cd Thanks @​kkkhs! - Fixed #11328: lint/nursery/useExpect now recognizes Vitest Browser Mode expect.element() calls as assertions.

• #11343 9b98211 Thanks @​johncarmack1984! - Fixed #11311: the CSS parser now accepts Tailwind container-query variant names in @variant, such as @xl and @max-xl. These previously produced a parse error and a noUnknownAtRules diagnostic.

  @variant @xl {
    div {
      background: red;
    }
  }

• #11220 3e8c488 Thanks @​santichausis! - Fixed #9541: noUndeclaredVariables, noUnusedImports, and noUnusedVariables now correctly recognise exported variables and functions declared in one embedded <script> block as usable from a sibling <script> block, in Svelte's <script module>/<script> pair and Vue's non-setup <script> blocks.

  For example, Biome no longer reports greet as undeclared in the following Svelte component:

  <script module>
