Recent updates
aws-sdk-v0.7.0
This release mainly adds support for specifying a Workspace ID via the `anthropic-workspace-id` header on many additional beta endpoints. The codebase also includes a small internal change to SSE streaming chunk handling and several additive TypeScript type export updates.
Featuresfoundry-sdk-v0.4.5
foundry-sdk v0.4.5 is a small release that only refreshes example platform model IDs. No API, behavior, or runtime changes are described in the release notes.
bedrock-sdk-v0.33.4
bedrock-sdk v0.33.4 is a minor release that only refreshes example content, specifically updating platform model IDs used in the SDK examples. There are no stated API changes, bug fixes, or security updates in these release notes.
vertex-sdk-v0.19.7
vertex-sdk v0.19.7 contains a non-functional documentation/examples update. The release refreshes platform model IDs used in the examples, with no explicit API, behavior, or compatibility changes described in the notes.
sdk-v0.124.0
SDK v0.124.0 adds new API capabilities around usage reporting (Claude Tag category and user breakdowns), organization compliance settings typing, and expanded support for sending a workspace ID on more endpoints. It also includes bug fixes in message resource custom-code merging and in tooling around agent-toolset file/directory ownership.
Featuressdk-v0.123.0
SDK v0.123.0 expands multiple beta surfaces, including user profile support for external_user_onboarded_at and organization compliance settings, plus additional beta schema work (memory store and toolset related). The release notes also call out a bundling fix to prevent credential file access in non-Node environments.
BreakingFeaturesaws-sdk-v0.6.6
aws-sdk v0.6.6 is documented as fixing AWS credential precedence to prefer environment credentials over AWS_PROFILE, and fixing SigV4 signing when query parameters repeat. The code diff, however, includes additional SDK-wide API and type changes (especially in beta files/skills namespaces) and several behavioral changes in core request/stream/upload handling that are not covered by the aws-sdk release notes.
bedrock-sdk-v0.33.3
This release (bedrock-sdk v0.33.3) includes AWS Bedrock specific bug fixes related to credential resolution and SigV4 request signing. These changes improve compatibility in environments where credentials may come from environment variables or where URLs contain repeated query keys.
sdk-v0.122.0
SDK v0.122.0 updates the API types and request-shaping for beta files and skills namespaces, aligning them with the GA shapes and removing reliance on dated beta header pins. It also includes several client and session robustness fixes, plus a behavior change for webhooks that requires passing headers when calling unwrap().
BreakingFeaturesgoogle-cloud-sdk-v0.0.11
Version 0.0.11 is a minor maintenance release with changes limited to example code. It removes redundant Promise error handling boilerplate in the examples and does not indicate any API, behavior, or configuration changes.
bedrock-sdk-v0.33.2
Release bedrock-sdk v0.33.2 (as described in the provided release notes) is a single bug fix: it prevents sending ambient first-party credentials to the Mantle endpoint. The accompanying diff shows many additional repository-wide changes (documentation, generated API surface, and new ecosystem test/CI additions) that are not reflected in the provided bedrock-sdk release notes.
vertex-sdk-v0.19.6
vertex-sdk v0.19.6 is a small maintenance release with changes limited to example code. The release notes indicate only cleanup of redundant error-handling boilerplate in examples, with no stated API, behavior, or dependency changes.
sdk-v0.121.0
SDK v0.121.0 adds new API capabilities for thinking display modes and Organization API endpoint support, plus helper improvements for structured outputs using Standard Schema. It also includes bug fixes around tool runner behavior and published TypeScript type references for Node.js environment types.
Featuresgoogle-cloud-sdk-v0.0.10
Release v0.0.10 contains an internal maintenance change only, switching to a single pnpm workspace lockfile. No API, functionality, or user-facing behavior changes are described in the release notes.
aws-sdk-v0.6.5
The provided release notes for aws-sdk v0.6.5 only mention an internal repository change: consolidating to a single pnpm workspace lockfile. The actual code diff for this release contains multiple additional outward-facing changes in the underlying TypeScript SDK, especially around response metadata and newly exposed APIs.
foundry-sdk-v0.4.4
Release v0.4.4 contains an internal build/release chore related to dependency management. It switches the project to use a single pnpm workspace lockfile, with no documented API or runtime behavior changes.
bedrock-sdk-v0.33.1
Release notes for bedrock-sdk v0.33.1 only mention an internal chore: switching to a single pnpm workspace lockfile. The actual code diff shows substantially more than that, including new agent tool configuration types, significant changes to the beta environments work poller and worker behavior, and a new session memory sync subsystem with hardened filesystem confinement.
SecurityFeaturesvertex-sdk-v0.19.5
Release v0.19.5 contains only an internal maintenance change. The notes indicate the project now uses a single pnpm workspace lockfile, with no documented user-facing API or behavior changes.
sdk-v0.120.0
Release sdk v0.120.0 adds managed agents web search configuration and introduces work around self-hosted sandbox memory. The code diff also contains several substantial internal behavioral and typing changes in beta environment workers and the agent toolset, including stricter sandboxing and new session memory sync logic.
SecurityFeaturesbedrock-sdk-v0.33.0
bedrock-sdk v0.33.0 advances the Files and Skills APIs to general availability (GA) and adds support for additional toolsets. This release also includes computer use and browser use toolsets, expanding the capabilities you can request from the API.
