Note

High Risk
Rewrites release and promotion CI workflows that control how SDK changes reach production and how GitHub releases are created. API surface changes are additive but the automation path is critical infrastructure.

Overview
Releases 0.89.0 with two API features and a redesigned release pipeline.

API features
Adds geographic region (us-east / eu-west) across browser and browser-pool create params, responses, and list filters. Region is fixed at create time and plan-gated.

Extends GET /org/limits with plan-derived managed-auth fields: auth_connections_used, max_auth_connections, and min_health_check_interval_seconds.

Release automation
Replaces the legacy stainless/release promotion PR with a next → main versioned release flow. Staging promotion now merges validated changes into production next (with conflict recovery PRs), and release-please opens/updates the versioned PR from next then creates the GitHub release on merge to main.

Nullable limit tagged as required

High Severity

MaxAuthConnections is documented as null for unlimited plans but tagged api:"required", unlike DefaultProjectMaxConcurrentSessions and other null-means-uncapped int limits that use api:"nullable". A JSON null decodes to 0 with Valid() false, so capacity checks like AuthConnectionsUsed >= MaxAuthConnections treat unlimited as exhausted even at zero usage.
