  "title": "opencode v1.15.12 stabilizes acp-next routing and session startup for AI agents",
  "summary": "The release upgrades the acp-next integration to reliably route prompts, slash commands, and usage updates while significantly reducing first-session startup latency and fixing permission prompt handling.",
  "contribution": "Standardizes prompt and command routing through the acp-next protocol, cuts first-session initialization time, and ensures permission prompts and session directories are handled correctly during agent handoffs.",
  "impact": "Developers running AI coding agents will see fewer dropped commands and faster session startup when switching models or opening new workspaces. The update stabilizes prompt and slash-command routing through the acp-next transport, cuts first-session initialization latency, and fixes permission prompt handling. Teams should monitor whether the experimental OpenAI WebSocket fallback introduces connection drops under heavy load, and verify that adaptive reasoning controls for Anthropic Opus 4.7+ apply correctly across persisted session directories.",
