[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.
• 🛠️ Dependable tools, prompts, and UI streaming: Keep streamed tool arguments intact, enforce MCP tool policy, prevent invented line numbers, and smooth chat updates.
