v2.2.0

Added

• Expanded provider surface — Added generated API support for the latest Conversational AI vendors and configuration types, including Dify LLM and Generic Avatar.
• Interaction language handling — AgentKit now consistently derives REST asr.language from TurnDetectionConfig.Language while keeping provider-specific STT language values under asr.params.
• Deepgram keyterm — Added Keyterm support on DeepgramSTT, serialized as asr.params.keyterm.

Changed

• MiniMax managed presets — MiniMax preset-backed TTS now keeps the preset model as an internal hint while sending only supported partial TTS settings such as voice_setting.voice_id.
• Vertex AI LLM routing — NewVertexAILLM now keeps project and location in the generated endpoint URL instead of duplicating them in llm.params.

Fixed

• Provider wire keys — Corrected alias-sensitive TTS payloads so Google TTS emits VoiceSelectionParams and AudioConfig, Rime TTS emits modelId, and Murf TTS preserves voiceId.
• AgentKit request validation — Start request validation preserves generated wire keys while still allowing preset and pipeline-backed partial configs.
• Request body coverage — Added regression tests for BYOK, preset-backed, mixed preset/BYOK, and pipeline override request shapes across provider configurations.
• TTS vendor tests — Added Microsoft TTS coverage to the vendor helper test matrix.
