Key updates include additions and modifications to the beta user profiles API (adding external user onboarded at and removing relationship in favor of access type ), support for organization compliance settings, user-profile ordering, and updates to schemas for memory stores and toolsets. Bug fixes include resolving the base URL from AWS regions when skipping auth and passing options, attaching results to GA raw/streaming response wrappers for batches, properly deriving multipart filenames for file tuples, and removing unused wire aliases. Internal changes include dropping the unused distro dependency and refactoring discriminated union types to use UnionDiscriminator .
