About Anthropic SDK (TypeScript)
The TypeScript SDK tracks the platform's new surfaces while its provider packages tag empty commits.
The core sdk package moves quickly against the API — the latest release adds files and memory store operations, skill and user profile updates, and helpers for reading the workspace ID out of response headers, while removing a mid-conversation system content block the API no longer supports. Session-runner reliability got attention too, with tool-result sends now retried for at least the lease TTL. The Bedrock, Vertex, and Foundry packages, meanwhile, keep publishing versions whose entire changelog is an empty commit to trigger builds.
