• breaking(deps): require svelte 5.46.4 or later (#1271)

  • vitePlugin.hot in svelte.config.js use compilerOptions.hmr instead
  • vitePlugin.ignorePluginPreprocessors in svelte.config.js no longer needed

  • plugin.api.sveltePreprocess of other vite plugins Update affected plugins to a newer version or remove them. See docs for more information.
