When selecting a model in the CLI, if you have a pinned older model version (e.g., claude-sonnet-4-5), the selector now shows a helpful hint like "Newer version available · select Sonnet for claude-sonnet-4-6", guiding you to the latest version.
Evidence
Function o_z returns description: "Newer version available · select ${alias} for ${currentVersionName}" (search for "Newer version available")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
