Note

Medium Risk
The credential fields type change from map to ordered array is a breaking change for TypeScript callers; org limit and AgentCard doc updates are additive/low risk.

Overview
Release 0.109.0 bumps package/version metadata and changelog; the substantive SDK changes are typed API updates for org limits and vault credentials/payments.

GET /org/limits responses now include concurrent_sessions_used and concurrent_sessions_available (nullable when usage cannot be read), so callers can see org-wide browser concurrency usage and remaining capacity alongside existing auth/vault limits.

Credential vault specs change shape: spec.fields on create/read is now an ordered array of field definitions/inputs, each with an explicit name, instead of a string-keyed map. Docs state that array order is preserved in collection forms—integrators should list fields top-to-bottom like the target site and update any code that built fields as an object.

AgentCard card items document optional card_id as an opaque AgentCard vaulted card ID to pass through unchanged (no assumed prefix/format).
