This PR was opened by the [Changesets release](https://github.com/changesets/action) GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to version-3, this PR will be updated.⚠️ ⚠️ ⚠️ ⚠️ ⚠️ ⚠️ `version-3` is currently in **pre mode** so this branch has prereleases rather than normal releases. If you want to exit prereleases, run `changeset pre exit` on `version-3`.⚠️ ⚠️ ⚠️ ⚠️ ⚠️ ⚠️ # Releases ## @sveltejs/kit@3.0.0-next.9 ### Major Changes - breaking: `handle`'s `resolve` is now typed to always return a `Promise` ([#16352](#16352)) - breaking: replace the `$lib` alias with `#lib` and remove `files.lib` config.
