[Release] anthropics/claude-code v2.1.173: v2.1.173

Claude Code v2.1.173 addresses two key fixes: normalization of Fable 5 model names that include a [1m] suffix (representing 1M context) by automatically stripping it, and elimination of a false "sandbox dependencies missing" warning on Windows systems when sandbox mode is enabled. These updates improve model name handling and reduce unnecessary startup warnings for Windows users.

Key Points

• •Fable 5 model names with [1m] suffix are now automatically normalized by stripping the suffix
• •The [1m] suffix indicates 1M context window included by default in Fable 5
• •Fixed spurious sandbox dependencies warning on Windows startup
• •Sandbox warning no longer appears when sandbox is properly enabled in settings
• •Improvements focus on model name consistency and reducing false-positive warnings
