  1. ### Minor Changes
  3. - Treat top-level await and `import.meta` as ES module markers, matching Node.js syntax detection so no explicit module type is needed. (by [@alexander-akait](https://github.com/alexander-akait) in [#21218](https://github.com/webpack/webpack/pull/21218))
  5. - Add a `bun` target that emits ESM and externalizes `bun:*` and node.js built-in modules. (by [@alexander-akait](https://github.com/alexander-akait) in [#21248](https://github.com/webpack/webpack/pull/21248))

Bindings that may be wrapped in runtime-condition `if` blocks (harmony imports, ConcatenatedModule external imports) continue to use `var` to preserve function scoping. (by [@alexander-akait](https://github.com/alexander-akait) in [#21010](https://github.com/webpack/webpack/pull/21010))
