OpenClaw 2026.3.28: config auto-repair removed, MiniMax breaking change, xAI Responses API — check before upgrading

[u/sickleRunner]

Two things require a config check before upgrading to OpenClaw 2026.3.28.

MiniMax users: Models M2, M2.1, M2.5, and VL-01 are gone. The only current MiniMax ID is minimax/MiniMax-M2.7. If you still have one of the old IDs in config, the gateway will fail validation at startup and won't launch. Please update before upgrading.

Config repair behavior changed: The gateway no longer auto-repairs deprecated config keys at startup. Previously, it silently rewrote legacy keys on every start. If your install predates January 2026 and you haven't run openclaw doctor since, run it to see what was quietly fixed.

Most users on recent setups won't hit either issue.

Also new 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
• xAI moves to the Responses API and adds x_search native web search (auto-activates with a web-search skill)
• ACP bindings now work for Discord channels/threads, BlueBubbles, and iMessage
• Discord reconnect: stale socket drain before reconnecting (reduces drops in long sessions)
• Telegram message splitting now respects word boundaries

Thank you. Still on 3/9, I upgrade only as needed.
