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
