Claude Code v2.1.175 Adds enforceAvailableModels to Constrain the Default Model; v2.1.174 Fixes /model Picker

Claude Code Docs·medium signal

On 2026-06-12 Claude Code shipped v2.1.175, adding an enforceAvailableModels managed setting so an availableModels allowlist now also constrains which model 'Default' resolves to — useful for orgs that must pin Opus 4.8 or block a tier. The same-day v2.1.174 added a wheelScrollAccelerationEnabled toggle for fullscreen mode and fixed the /model picker hiding the family that Default resolves to. This supersedes v2.1.173 (the suffix-normalization build covered last issue).
