Anthropic suspends Fable 5 and Mythos 5 due to US government directive
Anthropic is suspending access to its Fable 5 and Mythos 5 models for all customers in response to a US government export control directive. The government cited national security concerns, believing a method to bypass the model's safeguards has been discovered. This action affects all users, including foreign national Anthropic employees, though other Anthropic models remain unaffected. Anthropic disagrees with the severity of the finding and is working to restore access.

Claude Code v2.1.160: Security, Stability, and UX Improvements
This patch enhances Claude Code's security and stability by adding prompts for writing to sensitive shell startup and build-tool config files, preventing unintended command execution. It also improves user experience with fixes for session restoration, clipboard functionality on WSL, and responsiveness issues on Windows. These updates benefit all users, particularly those on Windows or relying on background sessions, with improved stability and a more robust security posture.
