Notes

rolldown-plugin-dts is now v0.29. tsdown passes dts options through to it unchanged, so its deprecations show up in your config too. Full details are in the rolldown-plugin-dts v0.29.0 release notes.

Migration

tsc-only dts options move under dts.tsc. The top-level build, incremental, parallel, eager, newContext and vue options still work but log a deprecation warning. Setting the same option at both levels throws an error. emitJs stays at the top level.

 export default defineConfig({
   dts: {
-    vue: true,
+    tsc: { vue: true },
   },
 })

tsgo (experimental, not covered by semver):

• @typescript/native-preview is no longer supported. Install TypeScript 7.1+ (typescript@7.1.0-beta), or point tsgo.moduleUrl at another build.
• On TypeScript 7.1+, tsgo.path is the API server executable, not the tsgo CLI. You usually don't need to set it.
• Declaration maps come only from compilerOptions.declarationMap: true in tsconfig; the sourcemap option no longer enables them.
• TypeScript 7.0 still works with a deprecation warning, but that backend will be removed soon.

   🧭 Migration Guide

Most users can upgrade directly. Before upgrading, run one final build with tsdown@0.22.14 and resolve all deprecation warnings.

• config:
  • bundle: false → unbundle: true; bundle: true can be removed
  • outExtension → outExtensions
  • publicDir / --public-dir → copy / --copy
  • removeNodeProtocol: true → nodeProtocol: 'strip'
  • injectStyle → css.inject
• deps:
  • inlineOnly / deps.onlyAllowBundle → deps.onlyBundle
  • skipNodeModulesBundle: true → deps.neverBundle: true
  • resolveDepSubpath now defaults to false; set it to true to preserve the previous behavior
• dts:
  • rolldown-plugin-dts was upgraded from 0.27.13 to 0.28.5
  • dts.oxc: true → dts.generator: 'oxc'
  • dts.tsgo: true → dts.generator: 'tsgo'; oxc and tsgo objects now only configure their respective generators
  • dts.volarPlugins → dts.customLanguages; rename each language's create hook to createVolarPlugins
  • Custom languages, including vue, now throw when combined with an incompatible generator
  • dts.cjsReexport was removed; dual-format builds now generate CJS declarations in a separate pass
• attw:
  • The default profile changed from strict to esm-only; set profile: 'strict' to preserve the previous checks
• programmatic API:
  • build() now returns { bundles, watch }; replace const bundles = await build() with const { bundles } = await build()
• requirements:
  • Node.js 25 is no longer supported; use ^22.18.0, ^24.11.0, or >=26.0.0
  • rolldown-plugin-dts now requires Rolldown 1.2.x
  • Legacy types and typesVersions fallbacks were removed; use TypeScript's bundler, node16, or nodenext module resolution
