Claude Code v2.1.299 ·

Model switch list is now filtered by the model you are using

The list of models a session may switch to now comes from a configuration whose entries apply only to particular current models

What

Claude Code has a check that decides whether a session switches to a different model. The list of models it chooses from used to be a plain list. It now comes from a configuration in which each entry says which current model it applies to. Only the entries that match the model you are using are considered.

Why

Fewer sessions may switch models, because an entry now applies only when your current model matches it.
