v2026.3.28 — Grok Responses API + Tool Hooks
Released: March 29, 2026 Theme: API compatibility + tool ecosystem expansion Breaking Changes: ⚠️ Qwen entry OAuth deprecation, config migration failure validation
Core Highlights
1. Grok Switches to Responses API
Migrates from the Chat Completions API to the new Responses API for better tool-calling and multi-turn support.
2. MiniMax image-01
Adds the image-01 image-generation model from MiniMax.
3. Unified File Upload
Cross-provider file-upload interface is unified, reducing per-API divergence.
4. requireApproval Tool Hook
New async approval mechanism — tool calls can pause for user confirmation. Great for high-risk operations.
⚠️ Breaking Changes
Qwen Entry OAuth Deprecated
The legacy Qwen OAuth sign-in flow is removed. Qwen users must switch to API-key authentication.
Config Migration Failure Validation
Upgrades validate the config file first. Malformed configs block the upgrade and show a fix guide.
Upgrade Recommendations
- Qwen users: get an API key from the Qwen portal first
- Users with custom tools: consider
requireApprovalfor stricter security - Everyone else: safe to upgrade
