Changelog and deprecation policy

The OpenAPI contract and release notes define public interfaces. Adding optional fields is usually compatible; removing fields, changing semantics, or narrowing a committed range will include migration guidance and a stated window.

Clients should ignore unknown response fields, send only declared request fields, and avoid depending on error-message text. There are currently no formal deprecations listed.

2026-09-26 · Chinese model guide and SDK source 0.3.0

• Added DeepSeek, Kimi, MiniMax and Zhipu GLM integration guidance, including GLM's missing Responses path and catalog/entitlement requirements.
• Added typed listPublicModels in all three SDKs without reading or sending credentials; intersect IDs with listModels to select authorized models.
• Added extensible TypeScript Chat types for reasoning and tool calls, three-language preservation regressions and SSE fragment coverage.
• Updated both locales across home, models, about, pricing and help pages with Chinese model details and integration links.

See Chinese model integration and SDK migration. This is a source release.

2026-09-26 · SDK source 0.2.0

• All three SDKs gain protocol gateway operations and support platform Direct keys alongside Embedded tokens; Embedded self-service authorization stays unchanged.
• TypeScript adds Chat / Responses / Messages / Gemini SSE, cancellation, and request options. Swift/Kotlin gain non-streaming wrappers and explicitly reject streaming misuse.
• Updated Claude Chat / Responses compatibility, Messages token counting, and native Gemini integration guidance.
• Corrected catalog guidance: the public catalog supplies protocols; authenticated /v1/models supplies accessible IDs.
• Updated Chinese and English product descriptions, model selection, SDK migration, and stream completion guidance.

This is a source release, not a claim of public package publication. See official SDKs for migration and limits.
