What

Claude Code ships a bundled reference document listing the models it can use. In this release, the file's name changed to reflect a new content hash (models-b6cb6bd6.md.zst), which means the underlying document was refreshed with new content.

Why

This keeps the model reference Claude Code relies on internally up to date, though the finding does not specify what information in the document changed.

How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubtWhat specific content changed in the model reference document is not known, only that the file's hash-derived name is new.
