OpenAI Agents Python v0.14.8 is a maintenance release that fixes two critical issues: preserving MCP re-export import errors and properly delimiting sandbox prompt instruction sections. The release includes documentation improvements and welcomes a new contributor to the project.

Claude Code v2.1.123 is a patch release that fixes a critical OAuth authentication bug. When the experimental betas feature flag was disabled via the `CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS=1` environment variable, OAuth authentication would enter a 401 retry loop, preventing successful login. This fix resolves the authentication failure and allows users with experimental features disabled to authenticate properly.
