Zoo Code v3.86.0

[3.86.0]

• ✨ New model support: Use GPT-6.1 Sol, get the corrected Claude Opus 5.5 output budget, and select DeepSeek V4.1 Flash on OpenCode Go.
• 🧭 Reliable task aborts and interruptions: Preserve the first abort reason, reset stream-abort state for each request, and stop interrupted tasks from replaying rejected subtasks.
