Changelog

The API now supports date-based version pinning with the Speechify-Version request header.

• Current version: 2026-06-25
• Header format: YYYY-MM-DD
• Resolution order: request header, workspace default, oldest supported version
• Migration path: official SDKs pin their build-date version automatically; raw HTTP callers should send Speechify-Version explicitly.

GET /v1/agents/llm-models — platform_default is now nested

The platform-default LLM pair moved from two top-level fields into a single object.

• Before (pin 2026-06-24 or earlier): top-level platform_default_provider and platform_default_model strings.
• After (2026-06-25 and later): a platform_default object with provider and model fields.
• Migrate: read platform_default.provider / platform_default.model instead of the flat fields.
