Patch Changes

• #8509 574a909 Thanks @ematipico! - Added support for parsing and formatting the Svelte {#await} syntax, when html.experimentalFullSupportEnabled is set to true.

  -{#await promise  then name }
  +{#await promise then name}
  
  -{:catch    name}
  +{:catch name}
  
  {/await}

• #8316 d64e92d Thanks @washbin! - Added the new nursery rule noMultiAssign. This rule helps to prevent multiple chained assignments.

  For example, the following code triggers because there are two assignment expressions in the same statement.

  const a = (b = 0);

• #8511 16a9036 Thanks @ematipico! - Improved the diagnostics of the rules useSortedClasses and noUnnecessaryConditions. The diagnostics now state that these rules are a work in progress and link to the relevant GitHub issue.

• #8521 a704be9 Thanks @ToBinio! - Added the nursery rule useVueConsistentDefinePropsDeclaration, which enforces consistent defineProps declaration style.

  Invalid

  <script setup lang="ts">
  const props = defineProps({
    kind: { type: String },
  });
  </script>

  Valid

  <script setup lang="ts">
  const props = defineProps<{
    kind: string;
  }>();
  </script>

• #8495 b573d14 Thanks @taga3s! - Fixed #8405: noMisusedPromises now emits warnings/errors when a function returns union types such as T | Promise<T> which is used in conditionals.

  const a = (): boolean | Promise<boolean> => Promise.resolve(true);
  if (a()) {
  } // Now correctly flagged

• #8493 5fc24f4 Thanks @ematipico! - Added support for parsing and formatting the Svelte {#each} syntax, when html.experimentalFullSupportEnabled is set to true.

  - {#each items   as item  }
  + {#each items as item}
  
  {/each}

• #8523 5f22f1c Thanks @ematipico! - Improved the diagnostics of nursery rules. Added a message to diagnostics emitted by nursery rules, so that users are aware of nature of nursery rules.

• #8521 a704be9 Thanks @ToBinio! - Update useVueDefineMacrosOrder to only run on <script setup> blocks.

• #8344 7b982ba Thanks @ematipico! - Reduced the system calls when running the CLI. The performances might be noticable in big projects that have multiple libraries and enable project rules.

• #8529 8794883 Thanks @mdevils! - Fixed 💅 useExhaustiveDependencies false positive on aliased keys #8499: useExhaustiveDependencies properly handles aliased destructured object keys when using stableResult configuration.

• #8509 574a909 Thanks @ematipico! - Added support for parsing and formatting the Svelte {#snippet} syntax, when html.experimentalFullSupportEnabled is set to true.

  -{#snippet    foo() }
  +{#snippet foo()}
  
  {/snippe}

• #8531 6b09620 Thanks @taga3s! - Fixed #8472: The CSS parser can now accept multiple comma separated parameters in :active-view-transition-type.

• #8536 efbfbe2 Thanks @dyc3! - Fixed #8527: Improved type inference where analyzing code with repeated object property access and assignments (e.g. node = node.parent, a pattern common when traversing trees in a while loop) could hit an internal type limit. Biome now handles these cases without exceeding the type limit.
