Claude Code v2.1.239 Released: Cost Estimates Enhanced, Fullscreen Renderer Extended, Numerous Fixes

What's changed

• Cost estimates (/cost, status line, --max-budget-usd) now include the 1.1× US-only-inference premium for data-residency workspaces
• Added the one-time fullscreen renderer offer on Bedrock, Vertex, Foundry and other previously excluded setups; new installs there now start in fullscreen
• Added /claude-api upgrade to migrate Python projects from anthropic 0.x to 1.x, and updated the skill's Python reference for 1.x (timeouts use anthropic.Timeout, not httpx.Timeout)
• Cloud sessions: plugins synced from claude.ai now show as name@synced, work with claude plugin enable/disable <name>@synced, and never override a same-named plugin you installed
• Alpine/musl builds: native image paste, clipboard, and audio-capture add-ons now load (musl-built binaries instead of glibc ones refused by the runtime)
• The usage-limit message shown when your monthly spend limit is already used up now also says when your session or weekly limit resets
• Fixed Bedrock streaming behind proxies that strip the response Content-Type header, which silently doubled billed API calls by re-running every turn non-streaming
• Fixed Claude Code hanging at startup behind an HTTPS proxy when using Bedrock with an SSO profile and awsAuthRefresh — the credential pre-check now honors HTTPS_PROXY
• Fixed a raw crash dump when starting Claude Code from a directory that no longer exists; it now prints a clear message
• Fixed Edit and Write calls pausing for about 5 seconds in JetBrains IDE terminals when the Claude Code plugin is connected
• Fixed a race where pressing Esc with a prompt queued could let the next turn finish early, leaving the session idle while Claude was still working and letting a later resubmit repeat actions
• Fixed WebFetch retaining expired page content in memory for the whole session instead of the intended 15 minutes
• Fixed cloud sessions (Claude Code on the web, desktop and mobile apps) resuming out of plan mode after an idle worker restart
• Fixed MCP elicitation forms taller than the terminal being clipped in fullscreen mode: the form now fits the window, with hidden fields reachable by scrolling and Accept/Decline always visible
• Fixed remote MCP servers staying failed after a transient 5xx on a mid-session reconnect in cloud sessions or via SDK setMcpServers()
• Fixed custom session titles disappearing from /resume after more than ~64 KB of conversation was written following the rename
• Fixed claude -c/resume picking up sessions from a different directory whose path differed only by characters like _, -, or .
• Fixed /resume and the agents view showing a session as recently changed (and reordering it) when only its file was touched or it was merely reopened
• Fixed /resume in all-projects mode telling you to cd into a deleted directory (e.g. a removed worktree); such sessions now resume in the current directory
• Fixed the dark-ansi theme rendering expanded tool results in fullscreen mode with text the same color as the background
• Fixed the fullscreen renderer prompt reappearing on every launch when it could never be answered; it now stops after being shown on three launches
• Fixed .worktreeinclude patterns starting with **/ silently matching nothing when the target lived in a gitignored directory
• Fixed agents, skills, and commands whose .md file starts with a UTF-8 BOM being silently ignored
• Fixed /insights echoing literal <message> tags in its response on some models
• Fixed marketplace metadata.pluginRoot having no effect: bare plugin source names now resolve under it as the docs describe
• Fixed mouse movement in browser-based terminals inserting text like "35;150;7M" into the prompt when a mouse report arrived split across writes
• Fixed custom theme overrides for the effort/ultracode status badge colors being ignored
• Fixed OpenTelemetry trace fragmentation: tool executions deferred by a PreToolUse hook now resume in the original turn's trace instead of starting a new trace
• Fixed vim mode in the agent view: Escape now switches to NORMAL mode and keeps your text instead of clearing the prompt
• Fixed the selection:copy keybinding silently dropping a text selection that had been extended with Shift+Arrow keys
• Fixed the /voice startup tip still appearing after voice dictation was enabled via the voice.enabled setting
• Fixed shell-mode (!) Tab completion dropping the ./ from a ./script path, which left a command the shell couldn't run
• Fixed fullscreen mode answering a permission prompt or pressing a button when you clicked the terminal window only to bring it back into focus
• Fixed slash-command panels (e.g. /config, /model) in fullscreen mode covering the latest messages; the conversation now stays pinned above the panel
• Fixed the /workflows detail dialog overflowing the terminal and losing its header off-screen when opened while Claude is still responding
• Fixed the Linux sandbox making a nonexistent .git/config.worktree unreadable, which broke every sandboxed git command in repos with extensions.worktreeConfig set
• Fixed hooks failing with "posix_spawn ENOENT" after the session's working directory was deleted; they now run from the project root or home directory instead
• Fixed claudeMdExcludes not excluding a symlinked .claude/rules file when the pattern names the rules directory or the symlink rather than its target
• Fixed runaway session-title syncing to Remote Control when two Claude Code processes shared one background job's state (2.1.232 regression); title updates are now deduplicated and rate-limited
• Fixed sessions whose title starts with / being unaddressable by SendMessage and shown as "(untitled)" in ListAgents
• Fixed Ctrl+W, Ctrl+U, Ctrl+K, Option+Backspace, Option+D and vim df/dt leaving a broken [Pasted text #N] placeholder when the cursor was inside it
• Fixed masked (password-style) inputs such as the login code field letting their text be pasted back with Ctrl+Y elsewhere or saved to prompt history when cleared with double Esc
• Fixed Ctrl+Backspace deleting one character instead of a word in search boxes
• Fixed a request rejected by an organization policy check being re-sent before the rejection was shown
• Improved the reminder shown after compaction so a skill's original arguments are not re-run as a new request
• Long file paths on tool-use rows now truncate in the middle to stay on one line
• Remote sessions keep sending keep-alives while a long SessionStart or Setup hook runs, so the container is not idle-reaped mid-hook
• /goal: repeat check-ins on long-running background work now back off (30 min, then 1 h, then every 2 h) instead of repeating every 30 minutes
• /goal: resuming a session from the claude --resume picker now restores its active goal
• ListAgents now tells a session its own name (the one peers use to message it), and SendMessage to your own name says so instead of "no agent named …"
• ListAgents and /list-agents now list your live teammates (previously only subagents and other sessions appeared, so a reachable teammate looked absent)
• keybindingFlavor: "readline" now also matches Bash for word keys: Alt+F and Ctrl/Option+→ stop at the end of the word, Alt+D deletes to it (Ctrl+Y pastes it back), and punctuation separates words
• Persistent retry mode (CLAUDE_CODE_RETRY_WATCHDOG) now fails immediately on organization spend-limit and out-of-credits errors instead of waiting indefinitely for a reset
• Claude in Chrome: /clear now closes the session's Chrome tab group, and empty groups are closed on /resume and when Claude Code exits
• Remote sessions: images uploaded from mobile now include their saved file path, so Claude can copy them into files it creates
• Claude Code on the web: requests from Bash and other tools to non-API anthropic.com hosts (e.g. www, docs) now go through the session's network proxy, so your environment's allowed domains apply
• Remote Control: clearer message and claude doctor wording when Remote Control isn't enabled for your account
• Windows: cross-session messaging is now available, so Claude Code sessions across your machines can message each other with SendMessage and find each other with ListAgents, as on macOS and Linux
• [VSCode] "View usage" in the usage-limit banner now sits inline with the warning text instead of floating mid-banner
