Claude Code 2.1.305 fixes the 2.1.304 regression that broke every request on Vertex, Bedrock, and some gateways

Released Oct 20, it now retries without tool search when a provider or gateway rejects it, and adds sandbox.allowNestedUserNamespaces so Linux sandboxed commands like Chromium or rootless podman can run, at the cost of bypassing the sandbox's file protections. It also fixes bare-repo worktrees starting from local HEAD instead of the default branch and stops workflow resumes re-running finished pipeline() and parallel() agents.
