## [0.134.0](https://github.com/anthropics/anthropic-sdk-typescript/compare/sdk-v0.133.0...sdk-v0.134.0) (2026-10-14)

  If your app registers a global tracer provider, the SDK will create spans with it after upgrading, and they'll be exported with the rest of your traces. Requests will also get trace context headers from the global propagator. To disable, pass `openTelemetry: false` to the client or set `ANTHROPIC_OPEN_TELEMETRY=false`.

## 0.122.0 (2026-08-27)

Full Changelog: [sdk-v0.121.0...sdk-v0.122.0](https://github.com/anthropics/anthropic-sdk-typescript/compare/sdk-v0.121.0...sdk-v0.122.0)

### Features

* **api:** beta files/skills namespaces use GA shapes; drop dated beta header pins ([45d693a](https://github.com/anthropics/anthropic-sdk-typescript/commit/45d693a66bc7fb1af66d9c4e3625f6d6f64bae59))

  The beta Files and Skills namespaces (`client.beta.files`, `client.beta.skills`) no longer send the `files-api-2025-04-14` / `skills-2025-10-02` headers and return the same shapes as `client.files` / `client.skills` (with `Beta`-prefixed type names). Requests that still send those headers on raw HTTP keep receiving the beta shapes.

  Changes in the beta namespaces:
  - `client.beta.skills.delete()` now deletes a Skill together with all of its versions (previously refused while any version existed). It returns `BetaDeletedSkill` (was `SkillDeleteResponse`).
  - Beta Messages type `BetaSkill` (the `{type, skill_id, version}` entry in `BetaContainer.skills`) is renamed `BetaContainerSkill`; the request-side `BetaSkillParams` keeps its name. `BetaSkill` now names the Skill object returned by `client.beta.skills.create()` / `retrieve()` / `list()` (replacing `SkillCreateResponse` / `SkillRetrieveResponse` / `SkillListResponse`), and skill versions are `BetaSkillVersion` / `BetaDeletedSkillVersion` (replacing `Version*Response`).
  - `client.beta.files.list()` returns a `BetaFileMetadataPageCursor` (`PageCursor<BetaFileMetadata>` with `data` / `next_page`) and `FileListParams` paginates with `page` / `ids` (was `BetaFileMetadataPage`, a `Page<BetaFileMetadata>` with `data`, `has_more`, `first_id`, `last_id` and `before_id` / `after_id`); `for await` auto-pagination is unchanged. `BetaSkill` uses `display_name` (was `display_title`, also in `SkillCreateParams`) and `latest_version_id` (was `latest_version`), and `BetaSkillVersion` is addressed by its `skver_…` `id` (the Unix-timestamp `version` field is gone).
