Biome v2.3—Let's bring the ecosystem closer

Biome v2.3 introduces experimental support for formatting and linting Vue, Svelte, and Astro files, including JavaScript/TypeScript in script tags and CSS in style tags. The release adds a refined ignore syntax with single (!) and double (!!) exclamation marks to control file indexing for type inference versus complete exclusion. Native Tailwind v4 support is now available as an opt-in feature. Several lint rules have been promoted from nursery to stable groups, and the CLI gains enhanced --skip and --only flags that accept lint domains. New reporters (checkstyle and RDJSON) and CLI flags provide better control without configuration files. The init command now automatically detects ignore files and dist folders for smoother onboarding.
