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/adapter-bun@1.0.0-next.1 ### Minor Changes - feat: add a Bun-native adapter with static file serving and single-executable support ([#16695](#16695)) ### Patch Changes - Updated dependencies [[`9b3d195`](9b3d195), [`385d378`](385d378), [`3782448`](3782448), [`d0d3a33`](d0d3a33), [`4b7a483`](4b7a483), [`e325d7d`](e325d7d), [`4f63c79`](4f63c79)]: - @sveltejs/kit@3.0.0-next.25 ## @sveltejs/kit@3.0.0-next.25 ### Minor Changes - feat: add an `applyReroute` helper for adapters that support split serverless function deployments ([#16665](#16665)) ### Patch Changes - chore: build streamed responses from async generators ([#16847](#16847)) - fix: tweak response logging for remote requests ([#16865](#16865)) - fix: discard invalidation results when a navigation completes while they load ([#16852](#16852)) - fix: route dev-server response logging through Vite's logger so it respects `logLevel` and `customLogger` ([#16858](#16858)) - chore: read build-time config from defines on the server instead of carrying it in `options` ([#16873](#16873)) - chore: read `options` from a single module instead of passing it through the server runtime ([#16871](#16871)) ## @sveltejs/adapter-netlify@7.0.0-next.10 ### Patch Changes - fix: correctly apply `reroute` results for apps configured with split serverless functions ([#16665](#16665)) - Updated dependencies [[`9b3d195`](9b3d195), [`385d378`](385d378), [`3782448`](3782448), [`d0d3a33`](d0d3a33), [`4b7a483`](4b7a483), [`e325d7d`](e325d7d), [`4f63c79`](4f63c79)]: - @sveltejs/kit@3.0.0-next.25 ## @sveltejs/adapter-vercel@7.0.0-next.8 ### Patch Changes - fix: omit ISR data endpoints for server-only routes ([#16731](#16731)) - fix: correctly apply `reroute` results for apps configured with split serverless functions ([#16665](#16665)) - Updated dependencies [[`9b3d195`](9b3d195), [`385d378`](385d378), [`3782448`](3782448), [`d0d3a33`](d0d3a33), [`4b7a483`](4b7a483), [`e325d7d`](e325d7d), [`4f63c79`](4f63c79)]: - @sveltejs/kit@3.0.0-next.25 Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com>

SSROptionsfields are build-time constants that already exist as defines for the client,__SVELTEKIT_EMBEDDED__and__SVELTEKIT_HASH_ROUTING__. The server took a second route to the same values throughoptions, thoughapp/paths/internal/server.jsalready reads__SVELTEKIT_APP_DIR__. This moves the server onto those two and adds defines forcsrf_check_origin,link_header_preload,paths_originandservice_worker.The app's global name was derived in five places:
exports/vite/index.jstwice,core/env.jstwice, andruntime/server/utils.jsinget_global_name, which read it back out ofSSROptions.version_hash. Two of them calledhash(config.version.name)separately.get_global_name(version_name, dev)incore/utils.jsis now the only derivation, and the server reads the result through__SVELTEKIT_GLOBAL_NAME__.SSROptions.versionhad no readers at all.csp,csrf_trusted_origins,service_worker_optionsandtemplatesstay put: a define is a textual substitution, so a structured value gets re-inlined at every read.Stacked on #16871.
