Note

Adds Agents Auth API (with invocation flow) and deprecates browser persistence, updating client, docs, and tests.

• Agents (new):
  • Introduces client.agents.auth with endpoints: create, retrieve, list.
  • Adds client.agents.auth.invocations: create, retrieve, discover, exchange, submit.
  • Wires resources into Kernel/AsyncKernel (including raw/streaming) and adds full types + tests.
• Browsers:
  • Marks persistence fields as DEPRECATED; clarifies timeout_seconds behavior and viewport defaults (1920x1080@25).
  • Deprecates DELETE /browsers by persistent_id; keep DELETE /browsers/{id}; tests updated to expect deprecation warnings.
• Browser Pools:
  • Docs/defaults tweaks: viewport default to 1920x1080@25; discard_all_idle default to false.
• Docs/Types:
  • README examples use stealth=True instead of persistence; api.md documents new Agents section.
  • Numerous model/type docstrings added; Pyright SequenceNotStr tweak.
• Meta:
  • Version bump to 0.23.0; OpenAPI sync (configured endpoints 82).

Refactors

• browser: Deprecated the persistence parameter/field across various browser-related types (e.g., BrowserCreateParams, BrowserCreateResponse, BrowserListResponse, BrowserPoolAcquireResponse, BrowserRetrieveResponse), recommending the use of timeout_seconds and Profiles instead. This also involved updating documentation and example code snippets in README.md and the CHANGELOG.md. (57af2e1)
