Recently shipped SDK v5.27.0 with a browser token guard, the Agent Skills API, and typed databases.

**Browser clients refuse tokens by default.** Constructing a client with `auth` in a browser page, web worker, or service worker now throws `BrowserTokenNotAllowedError`; per-request `auth` and OAuth client credentials reject the same way before anything is sent. Pass `dangerouslyAllowBrowser: true` to opt out — jsdom tests, for example. A client without a token still works in a browser, such as one pointed at your own server via `baseUrl`.

**Agent Skills reached the SDK, alongside typed databases.** `client.plugins.list()` and `client.plugins.retrieve()` browse plugins, and `client.skills.retrieve()` returns a signed archive URL; the SDK doesn't download or extract the files.

**The iOS app stayed on bug fixes.** Releases 1.7.334 through 1.7.346 all shipped bug fixes and performance improvements, with no new capabilities.

**Agent and session APIs from v5.26.0 still stand.** `client.agents` and `client.sessions` cover retrieval, queries, status and credit-limit updates, cancellation, and SSE streaming with retry before the stream opens. Write responses still honor `filter_properties`, and verification filters still accept `does_not_equal`. Meeting-notes block creation and the External Agents API GA remain available.
