Here, we record the addition and removal times of models, major functional updates, bug fixes, and release times of key versions. Each release keeps one brief line here; the per-entry summaries live in changelog/<version>/README.md, and every entry links its detail file.
-
[2026-08-26] Version 0.4.8:
glm-5.3-flashjoins the registry and reads images in a prompt and in a tool result, while every other GLM model refuses an image item instead of sending one. -
[2026-08-25] Version 0.4.7: the Gemini client splits function responses into their own contents, fixing the Vertex AI 400
Requests ending with a model turn are not supported.on messages that mix a tool result with text — an interrupted turn's carry-over resent with the next prompt, or tool outputs folded into a summarization request. -
[2026-08-21] Version 0.4.6:
deepseek-v4-flash-vision-expjoins the registry and reads images in a prompt and in a tool result, the DeepSeek client moves onto the OpenAI Responses protocol, every Responses client replays content items in the order the model produced them, an internalunusedevent never reaches a caller, and the playground plays a spoken answer as one clip and keeps its configuration across a reload. -
[2026-08-20] Version 0.4.5: streaming clients skip output they do not recognize unless
AGENTHUB_DEBUGis set,AutoLLMClientlists the model ids an endpoint serves, every client accepts default headers for endpoints that demand their own, GLM-5.3 andclaude-opus-5join the registry, and the OpenRouter entries move to theopenai-responsesclient. -
[2026-08-19] Version 0.4.4: thinking levels gain a
MAXtier aboveXHIGH, and each client maps the ladder onto its vendor's effort vocabulary (DeepSeek re-mapped to its current low/high/max values). -
[2026-08-18] Version 0.4.3: every streaming client skips the heartbeat events gateways inject on long generations, across the OpenAI Responses, OpenAI Chat Completions, Anthropic Messages, and Gemini protocols.
-
[2026-08-18] Version 0.4.2: generic OpenAI Responses and Anthropic Messages protocol clients covering OpenAI, OpenRouter, DeepSeek, Z.AI, and MiniMax (the generic chat client renames to
openai-chat), GPT-5.6 support,UniConfig.fast_mode, and the Claude and Kimi series clients unified with family-widetemperaturerejection. -
[2026-07-22] Version 0.4.1: Kimi K3, the Gemini 3.6 generation (gemini-3.6-flash, gemini-3.5-flash-lite), and GLM-5.2 support, a supported-model registry with USD/CNY pricing, context windows, and modalities, and the
UnsupportedParameterErrorparameter error class. -
[2026-07-20] Version 0.4.0: the
fidelitycontent-item payload replacessignature/phase(breaking), OpenAI-compatible clients replay the exact upstream reasoning field, Claude 5 support, and hardened tool-call streaming. -
[2026-06-01] Version 0.3.3: OpenAI-compatible embedding input format.
-
[2026-05-30] Version 0.3.2: Claude 4.8, a generic OpenAI Chat Completions-compatible client, abort support, agent skills, and a broad model refresh.
-
[2026-04-28] Version 0.3.1: Gemini TTS and image generation, GPT-5.5, the UModelVerse vendor, and automatic Claude caching.
-
[2026-03-11] Version 0.3.0: Claude 4.6 with adaptive thinking, GPT-5.4 with phase labels, Claude on Amazon Bedrock, and GLM-5.
-
[2026-01-22] Version 0.2.0: Gemini 3, Claude 4.5, GLM-4.7, GPT-5.2, and Qwen3 models, with prompt caching for Claude.
