October 2025 (ollama/ollama) delivered focused improvements in context handling, rendering, and reliability, with a tested rollback path to preserve correctness. Key items include: - Chat History Truncation and Shift Management implemented to control truncation and message shifting when context length is exceeded, with cross-runner embedding behavior updated; - Added a global RenderImgTags flag to render images as [img] tags in Qwen3VL for consistent rendering; - Routed qwen3 to the llama runner, removing qwen3 from the Ollama engine model list to improve stability and performance; - Defaulted Ollama connections to HTTPS port 443 to ensure secure communication; - Parser Warning Log Reduction: removed an unnecessary warning when the qwen3-vl parser encounters a closing <think> tag with no preceding content; - In response to early rollout feedback, initiated a safe rollback of the truncate/shift parameter changes to restore prior behavior while laying groundwork for a more robust reimplementation.

September 2025 (ollama/ollama): Focused on stabilizing Harmony integration, improving security-related error handling in remote chat, and clarifying cloud usage through documentation. Key actions included reverting disruptive Harmony parser/handler changes to restore existing parsing/handling of tool calls, enhancing unauthorized error handling to surface 401 API errors with a clear JSON payload and public key, and reorganizing cloud docs by renaming turbo.md to cloud.md and detailing cloud models, access methods (CLI, Python, JavaScript), and integration scenarios such as Open WebUI. These efforts improve reliability, security visibility, and developer experience for cloud-enabled workflows.
