Claude Code v2.1.131 Release Notes
Claude Code v2.1.131 fixes critical Windows VS Code extension activation issues and Mantle endpoint authentication problems.
The Claude Code development team has released version 2.1.131, addressing critical compatibility and authentication issues that were affecting Windows users and API integrations. This maintenance release focuses on stability improvements and bug fixes to ensure a smoother development experience across all platforms.
What’s New
Windows VS Code Extension Fix
This release resolves a critical issue where the VS Code extension would fail to activate on Windows systems. The problem was caused by a hardcoded build path in the bundled SDK, specifically related to a createRequire polyfill bug. Windows users should now experience proper extension activation without any platform-specific complications.
Mantle Endpoint Authentication Resolution
We’ve fixed authentication failures with Mantle endpoints that were occurring due to missing x-api-key headers. This fix ensures that API calls to Mantle endpoints now include the proper authentication headers, preventing connection failures and improving overall API reliability.
