Code formatting is now significantly faster in Java, Kotlin, TypeScript, Ruby, and Python SDKs by eliminating redundant operations, cutting some tasks from several seconds (and up to ~2 minutes in Java and Kotlin) down to just milliseconds.

Preview builds let you see how changes to your OpenAPI spec and Stainless config will affect your SDKs.

Pull requests to your GitHub repository that update the OpenAPI spec will build your SDKs and make a comment on the pull request with the results.

See our documentation on automating builds for more information and setup instructions.

If you participated in the beta by using build-sdk-action, we encourage you to migrate. See the build-sdk-action README for migration details.

For TypeScript and Python SDKs, we now enable you to download a built artifact of your SDK prior to release, after any build. In TypeScript this is a tarball with your compiled JavaScript files. In Python this is a wheel file. This allows you to inspect, manually test and distribute your SDKs prior to release.

Files configured to sync with external sources are now read-only by default in the Studio, with an option to unlock them for manual edits.
