…ecompressed (#16566) The remaining half of #10343, and the first concrete piece of #16565. #15182 stopped the header when `precompress` is `false`. It still goes out on every asset when `precompress` is `true`, because `sirv` sets `Vary` from its options rather than from the file, while `builder.compress` only compresses a fixed extension list. So a `.ico` or a `.png` advertises a variant that was never produced. Only extensions that were written but never compressed lose the header, since `setHeaders` sees the request pathname, not the file `sirv` resolved, and `/` or `/v1.0` may be serving `index.html.gz`. Commits are separated by layer so the kit-side and adapter-side changes can be reviewed apart. This rewrites the same `setHeaders` block as #16564, so whichever lands first, the other needs a rebase. --------- Co-authored-by: Rich Harris <richard.a.harris@gmail.com>

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.14 ### Major Changes - breaking: refresh all load functions/queries when clicking a link to the current URL ([#16572](#16572)) - breaking: only include routes with a `+page` or `+server` in `RouteId` ([#16580](#16580)) - breaking: require Node 22.17 ([#16597](#16597)) - breaking: `preloadCode` now takes a route ID (e.g. `/blog/[slug]`) instead of a pathname. Route IDs are not prefixed with `paths.base` ([#16576](#16576)) - breaking: remove deprecated `.run()` method from live queries ([#16573](#16573)) ### Minor Changes - feat: return the list of compressed files from `builder.compress` ([#16566](#16566)) - feat: add `page` and `endpoint` booleans to `$app/manifest`'s `routes`, and export a `ManifestRoute` type ([#16594](#16594)) - feat: add `PageRouteId` and `EndpointRouteId` to `$app/types` ([#16594](#16594)) ### Patch Changes - fix: generate valid `Path` types for routes with optional or rest params, several params in one segment, or escape sequences ([#16577](#16577)) - fix: decode all numeric character references, including above `ffff`, when crawling prerendered pages ([#16611](#16611)) - chore: deduplicate request hashing for serialized fetch responses ([#16499](#16499)) - fix: don't treat `Object.prototype` members as param matchers during validation ([#16612](#16612)) - fix: exclude routes without a page or endpoint from `routes` in `$app/manifest`, and remove directories with no route files from `LayoutParams` ([#16588](#16588)) - chore: reuse base64 and text decoding helpers ([#16608](#16608)) - fix: record the mime types of prerendered paths in the server manifest ([#16564](#16564)) - chore: only generate each route's resolution module once when prerendering ([#16576](#16576)) - fix: expand `[x+nn]` and `[u+nnnn]` escape sequences when resolving a route id to a pathname ([#16570](#16570)) - fix: allow routes to contain `[` and `]` via the `[x+5b]` and `[x+5d]` escapes ([#16569](#16569)) - chore: remove the dead `SSRState.fallback` field and name the server state fork semantics ([#16598](#16598)) - fix: import resolved peer dependencies as file URLs so project-relative resolution works on Windows ([#16618](#16618)) - fix: write generated tsconfig to `node_modules/$app/tsconfig.json` so that tools with simplified tsconfig resolution can find it ([#16589](#16589)) - fix: prerender and crawl pages whose `content-type` header carries a `charset` parameter ([#16567](#16567)) - fix: stream promised `read` results lazily instead of eagerly buffering them ([#16622](#16622)) - fix: correctly decode `[u+nnnn]` escape sequences above `ffff` ([#16611](#16611)) ## @sveltejs/adapter-auto@8.0.0-next.2 ### Patch Changes - fix: convert resolved adapter path to a file URL before importing, so builds work on Windows ([#16618](#16618)) - Updated dependencies [[`c3f58bb`](c3f58bb), [`b655dc7`](b655dc7), [`a70cc4f`](a70cc4f), [`b325afb`](b325afb), [`e76b3d7`](e76b3d7), [`58f47eb`](58f47eb), [`fe9d8d9`](fe9d8d9), [`0c7bbd7`](0c7bbd7), [`08d7e2a`](08d7e2a), [`f70f679`](f70f679), [`0624b26`](0624b26), [`0624b26`](0624b26), [`f4222ad`](f4222ad), [`089628b`](089628b), [`d8617b3`](d8617b3), [`c7369a1`](c7369a1), [`5e5e592`](5e5e592), [`60057c1`](60057c1), [`f70f679`](f70f679), [`38f1528`](38f1528), [`40092f3`](40092f3), [`ff4247e`](ff4247e), [`79a5de5`](79a5de5), [`a70cc4f`](a70cc4f)]: -

Picks up the
adapter-nodehalf of #13753.#16234 fixed
.icoby addingmimes['ico']to the sharedmrmimemodule. That works in dev and preview, which share one instance withsirv.adapter-nodebundles its own copy ofmrmimethroughsirv, so the patch never reaches it and.icostill goes out with an emptyContent-Typein production.The manifest already records the right type at build time, resolved through the patched lookup, so this reads it back rather than relying on
sirv's copy.
