The Usage Guides entry told readers the guide's DeepSeek sections no
longer applied to this release. That was true when v3.19.1 shipped, but
the guide has since been rewritten for it, so the warning now steers
people away from an accurate document.
Replace it with what the guide actually says: presets created after
3.19.1 connect directly, while providers saved earlier and
deepseek-v4-pro still need routing. Also drop MiniMax from the
Chat-format list — it moved to native Responses too — and name Zhipu GLM
instead.
The published release body on GitHub was updated to match.
