Claude Code 2.1.310

What's changed

• Added the Monitor tool and plugin monitors on Bedrock, Vertex, and Foundry, and when telemetry or nonessential traffic is disabled; long foreground sleeps are now blocked there too
• Fixed requests failing behind some gateways and compatible servers that reject the effort-2025-11-24 beta value or mid-conversation system messages; Claude Code now retries without them
• Fixed background cleanup deleting some recent files, such as pasted images, when cleanupPeriodDays is set to a very large value
• Fixed compaction after a "Prompt is too long" error keeping too much of a conversation with dense text, such as base64 or SVG, so the next request could fail again
• Fixed file read permission prompts not showing where a symbolic link leads
• Fixed a question's auto-continue timeout firing the moment the external editor closed after a long edit
• Windows: Fixed PreToolUse and PermissionRequest hooks letting a tool call through when Git Bash is missing and the hook's command is only quoted strings, such as a quoted path
• Improved auto mode's prompt before the first read outside the working directories: it now says when blocking those reads makes shell commands ask for permission
• Improved memory use of non-interactive sessions (-p, Agent SDK) during compaction when the transcript file is very large
• Improved a mod's Image to draw inside tmux with allow-passthrough and focus-events on, in kitty, Ghostty, and iTerm2 3.5+ with fullscreen rendering, where it showed only its alt text
• Linux: Improved /sandbox and the sandbox startup warning to name Ubuntu's AppArmor restriction on user namespaces, and how to lift it, when it keeps bubblewrap from starting the sandbox
• Changed the error for an MCP tool call that times out in a non-interactive session while the server's elicitation is unanswered: it now tells Claude that no answer came and not to repeat the call
• [VSCode] Fixed pressing Enter on the plan review card's "Send feedback and keep planning" button approving the plan instead of sending your comments back
• [VSCode] Fixed the panel showing "Something went wrong" after "Switch branch & continue" on a cloud session opened from Session history's Web tab
• [Cloud sessions] Added Claude Code cloud sessions and Remote Control permissions to Enterprise custom roles, so Owners can control access to each by role
• [Cloud sessions] Added a Choose file button to load a cloud environment's setup script from a file
• [Cloud sessions] Fixed failed saves and archives in the cloud environment edit dialog showing no error inside the dialog
• [Cloud sessions] Fixed failed routine API token actions showing only a toast; the error now appears in the routine edit dialog
• [Cloud sessions] Improved the session start checklist to show a cloud environment's setup script output in a scrolling box
• [Cloud sessions] Changed turning on Cloud sessions or Remote Control in admin settings to ask for confirmation and list the custom roles that have that permission
• [Cloud sessions] Changed the cloud environment dialog to open network access, setup script and environment variables from rows instead of listing every editor at once
• [Claude Tag] Fixed Claude Tag treating ! commands such as !restart and !help as ordinary messages when sent in bold, italic or strikethrough
• [Claude Tag] Fixed Claude Tag admin channel and workspace pages being replaced by a load error when a background refresh of the bundle list fails
• [Claude Tag] Fixed Claude Tag's spend limits page in admin settings reporting that no channels match a filter while channel names are still loading
• [Code Review] Fixed the Code Review admin section hiding its repositories and switches after a failed refresh of the repository list
• [Code Review] Improved the Code Review admin section to retry the first load and show one Try again banner when it still fails
