Internal Changes Section of the release
What
Three small internal changes:
A log message written when the prompt-cache relay is off has new wording. The prompt cache lets Claude reuse earlier parts of a conversation instead of processing them again.
An entry named prompt.autocomplete is added to an internal list.
The command.run entry now carries a short descriptive note.
Why
These affect log text and internal labels rather than anything you work with directly.

Anthropic's note
Upstream's own release notes for v2.1.292 name something this entry names, so the two are probably about the same change. Probably: the pairing is made on a shared name rather than on the words around it.
Added prompt.autocomplete , an event a mod hooks to add its own rows to the prompt box's autocomplete list
