ashwin-ant · ghdev · 2026-10-21
anthropics/claude-code released v2.1.305, adding sandbox.allowNestedUserNamespaces so sandboxed Linux commands can create user namespaces (Chromium, rootless podman), plus a watchdog env var to recheck lifted usage limits. Fixes include a 2.1.304 regression where gateways rejecting tool search broke every request, /effort and /autocompact not applying due to model name case or [1m] tags, MCP server overrides, worktree issues, compaction summary omissions, and Workflow resume re-running completed agents.
