version: 1.9.3
date: 2026-03-01
title: JSON tree viewer for structured output
---

## App

### New
- VSCode/Files: added file stat support in the extension bridge (thanks to @geekifan).
- Chat/Models: added arrow-key navigation for thinking-mode selection in model controls (thanks to @daveotero).
- Files: added HTML preview support in the file viewer (thanks to @nguyenngothuong).
- Chat/JSON: added an interactive JSON tree viewer with collapse/expand controls and richer color cues for easier inspection of large structured outputs (thanks to @nguyenngothuong).

### Improvements
- Security/Chat: user messages now escape raw HTML by default (thanks to @kalac2232).
- Desktop/Performance: reduced Tauri shell CPU/GPU overhead during longer sessions.
- Sessions/Drafts: draft chat config now stays synced with the selected draft target directory.
- Chat: improved error message readability with clearer styling and safer word-wrapping (thanks to @nguyenngothuong).
- Desktop/Settings: window vibrancy now correctly controls macOS window transparency, and settings copy now clarifies when full transparency changes take effect.
- Reliability/Proxy: hardened OpenCode proxy header handling (including identity-encoding normalization, compression-header cleanup, hop-by-hop response-header stripping) and suppressed expected SSE close noise.
- Terminal/Reliability: switched terminal transport to a pure WebSocket path with fallback handling.

### Fixes
- Mobile/Settings: fixed lingering settings drawers and removed extra top spacing for a cleaner, less obstructed mobile layout (thanks to @Jovines).
- Git/Worktrees: fixed worktree detection and reset stale integration state when switching contexts.
- Reliability/Proxy: restored proxied chat event streaming.
- Usage/Providers: added ZhipuAI quota tracking and fixed MiniMax coding-plan and GitHub Copilot overusage calculations (thanks to @kalac2232, @baruchvitorino, @ebrainte).

## VS Code

### New
- Files/Markdown: added filesystem stat support in the extension bridge to validate markdown targets reliably before file handling flows (thanks to @geekifan).
- Chat/Models: added arrow-key navigation for thinking-mode selection in model controls (thanks to @daveotero).
- Chat/JSON: added an interactive JSON tree viewer with collapse/expand controls and richer color cues for easier inspection of large structured outputs (thanks to @nguyenngothuong).

### Improvements
- Security/Chat: user messages now escape raw HTML by default (thanks to @kalac2232).
- Sessions/Drafts: draft chat config now stays aligned with the active draft target directory.
- Chat: improved error message readability with clearer styling and safer word-wrapping (thanks to @nguyenngothuong).
- Reliability/Streaming: proxy handling now normalizes identity encoding, strips conflicting compression headers and hop-by-hop response headers, and suppresses expected upstream SSE close errors to reduce noisy disconnect failures (thanks to @jwcrystal, @Jovines, @JiwaniZakir, @shekohex).

### Fixes
- Usage: added ZhipuAI quota tracking and fixed MiniMax coding-plan plus GitHub Copilot overusage calculations (thanks to @kalac2232, @baruchvitorino, @ebrainte).
