  1. ### Minor Changes
  3. - Default `experiments.typescript` to `"auto"`, enabling built-in TypeScript support on Node.js >= 22.6 when no TypeScript loader is registered. (by [@alexander-akait](https://github.com/alexander-akait) in [#21477](https://github.com/webpack/webpack/pull/21477))
  5. - Default `experiments.css`, `experiments.html` and `experiments.asyncWebAssembly` to `"auto"`, enabling built-in support unless a loader is registered for those files; modules with inline or hook-injected loaders (e.g. html-webpack-plugin templates) keep being parsed as JavaScript. (by [@alexander-akait](https://github.com/alexander-akait) in [#21477](https://github.com/webpack/webpack/pull/21477))
  7. - Add `output.resourceHints` to emit resource hints (`preload`/`prefetch`/`modulepreload`/`preconnect`), on by default for ESM output, plus `module.parser.<type>.urlHints`, `css.fontPreload` and `javascript.dynamicImportCssPreload`. (by [@alexander-akait](https://github.com/alexander-akait) in [#21477](https://github.com/webpack/webpack/pull/21477))

  13. - Wrap "weird" CommonJS modules into module concatenation instead of bailing out. (by [@alexander-akait](https://github.com/alexander-akait) in [#21477](https://github.com/webpack/webpack/pull/21477))
