Release notes

Claude Code 2.1.173

· 2 fixed

This release primarily focuses on user experience refinements through targeted bug fixes. Fable 5 model names with the "[1m]" context suffix are now automatically normalized and stripped, providing a cleaner and more accurate display for users of these models, given the 1M context is default. Furthermore, Windows users with the sandbox feature enabled will no longer encounter a spurious "sandbox dependencies missing" warning during startup, resulting in a smoother and less confusing launch experience. These improvements ensure greater clarity and stability for specific user groups.

Fixed2

  • Fixed Fable 5 model names with a `[1m]` suffix not being normalized — Fable 5 includes 1M context by default, so the suffix is now stripped automatically
  • Fixed a spurious "sandbox dependencies missing" startup warning on Windows when sandbox was enabled in settings
