Claude – v2.1.305

What’s in this update

What's changed

• Added sandbox.allowNestedUserNamespaces so sandboxed commands on Linux can create user namespaces (Chromium, rootless podman); this lets them get around the sandbox's file protections
• Added CLAUDE_CODE_RETRY_WATCHDOG_USAGE_LIMIT_RECHECK_MS so unattended retry mode (CLAUDE_CODE_RETRY_WATCHDOG) notices a usage limit that was lifted before its reset
• Fixed every request failing on Vertex, Bedrock and other providers when the endpoint or a gateway rejects tool search, and behind gateways with ToolSearch disallowed or left out of --tools (a 2.1.304 regression): Claude Code now retries without it
• Fixed /effort and /autocompact settings not applying when the model name differed from a modelOverrides value by letter case or a [1m] tag
• Fixed new worktrees in a bare repository sometimes starting from local HEAD instead of the default branch, and unchanged subagent worktrees sometimes not being cleaned up
• Fixed Bash commands on a full disk failing with a raw ENOSPC file path: the error now says the disk is full and that nothing ran
• Fixed an MCP server passed by a cloud session or by the SDK's setMcpServers being replaced later in the session by a same-named server from your own settings
• Fixed Claude naming the wrong model for a subagent's work after the subagent switched to a fallback model
• Fixed cloud sessions and teammates not telling Claude when a compaction had to leave the oldest messages out of its summary to fit
