Claude Code v2.1.123 Release Notes
Claude Code v2.1.123 fixes critical OAuth authentication issues when experimental betas are disabled, resolving 401 retry loops.
Claude Code v2.1.123 is now available, bringing an important authentication fix for users running with experimental features disabled. This maintenance release addresses a critical issue that was preventing proper OAuth authentication workflows.
What’s New
OAuth Authentication Fix
This release resolves a significant authentication issue that occurred when users had the CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS=1 environment variable set. Previously, this configuration would cause OAuth authentication to fail and enter an endless 401 retry loop, making it impossible for users to authenticate successfully.
The fix ensures that authentication flows work correctly regardless of experimental feature settings, providing a more stable experience for users who prefer to disable beta functionality.

- Via Package Manager: Run your standard update command
