OpenClaw 2026.3.28: Breaking Changes for MiniMax Users, Config Auto-Repair Removed

Breaking Changes Require Config Check

Before upgrading to OpenClaw 2026.3.28, check your configuration for two specific issues that could prevent the gateway from launching.

MiniMax Model Changes

MiniMax users: Models M2, M2.1, M2.5, and VL-01 have been removed. The only current valid MiniMax ID is minimax/MiniMax-M2.7. If your configuration contains any of the old model IDs, the gateway will fail validation at startup and won't launch. Update your config to use the new ID before upgrading.

Config Auto-Repair Removed

The gateway no longer automatically repairs deprecated configuration keys at startup. Previously, it silently rewrote legacy keys on every start. If your installation predates January 2026 and you haven't run openclaw doctor since then, run it now to see what was being quietly fixed in the background.

Most users on recent setups won't encounter either issue, but those with older configurations should verify before upgrading.

New Features in This Release

• openclaw config schema – prints the full JSON Schema for openclaw.json. Run openclaw config schema > schema.json and load it in VS Code for autocomplete support.
• xAI moves to the Responses API and adds x_search native web search functionality, which auto-activates with a web-search skill.
• ACP bindings now work for Discord channels/threads, BlueBubbles, and iMessage.
• Discord reconnect improvements: stale socket drain before reconnecting reduces drops in long sessions.
• Telegram message splitting now respects word boundaries.
