Note

Medium Risk
Project and limits URL changes can break callers on old API gateways; telemetry request shape changes may affect integrations that relied on the previous config-only model.

Overview
Release 0.57.0 aligns the Python SDK with OpenAPI updates: projects and project limits now call /org/projects (and /org/projects/{id}/limits) instead of the deprecated /projects routes—same client.projects API surface, different backend paths. Docs in api.md reflect the new URLs.

Browser create/update telemetry now uses BrowserTelemetryRequestConfigParam, which adds an enabled shortcut and updated semantics for when capture starts or stops; BrowserTelemetryConfigParam is removed. Response-side BrowserTelemetryConfig docstrings are tightened to describe active session config.

Tests and browser-routing mocks were updated for enabled: true in telemetry payloads and GET /org/projects.

Reason: This is an automated release PR for the Python SDK, not a direct change to kernel API endpoints or Temporal workflows; the actual code changes are not accessible in the PR metadata provided.
