1.3.9

[1.3.9] - 2026-08-14

Added

• Added inline file diffs for Write/Edit tool results in chat, including snapshot-backed previews and syntax-highlighted mutation cards.
• Added live sub-agent grouping in the CLI transcript (queued/running/completed, activity, tokens, model, elapsed) and matching desktop presentation phases.
• Added the OpenCode Zen provider preset (opencode.ai/zen) with GPT 5.6 Terra/Luna, GPT 5.5, Claude Opus/Sonnet 5, Grok 4.6, Qwen3.7 Max, DeepSeek V4, GLM 5.2, MiniMax M3, and Kimi models.
• Added shared ACP session-mode tool catalogs so the lead stays orchestration-only while sub-agents inherit the full implementation tool set and run in code mode.
• Added Native Worker AgentRuntimeToolError so recoverable tool failures become model-safe <system-remind> text instead of AOT resource keys such as IO_PathNotFound_Path.
• Added chat home insight copy, a hover-card titlebar mode switch with keyboard shortcuts, and motion helpers for popovers and preview rails.

Changed

• Refreshed chat presentation (tool cards, thinking blocks, skills menu, input area, workspace sidebar) around disclosure, diffs, and plan review.
• Bounded provider "context window exceeded" recovery to two overflow compressions per run so a misconfigured window cannot loop forever.
• Treated Home as project-scoped when a project is already selected, so new sessions from the home picker inherit the project.
• Removed the unused renderer prompt-optimizer module.

Fixed

• Fixed Windows ARM CI npm ci failing on hung Electron downloads by caching the binary, retrying install, and falling back to the npmmirror already used by electron-builder.
• Fixed Native Worker tool failures leaking framework resource keys to the model after AOT publish (UseSystemResourceKeys).
