Bug fixes and reliability improvements

2.1.225

Fri, 07 Aug 2026 16:00:00 GMT

Added gateway spend-limit support to Claude Code’s usage warning; the limit-reached message now names the cap, its reset time, and the operator’s message (requires the gateway on 2.1.225)
Added a workspace trust prompt to claude agents for untrusted directories, matching the behavior of claude
Fixed a transient 401 replacing a long-lived CLAUDE_CODE_OAUTH_TOKEN with a stored login’s short-lived token, breaking headless sessions until restart
Fixed MCP OAuth servers on macOS intermittently failing with a burst of 401 errors, as if never authenticated, after a keychain read timed out
Fixed auto mode counting a safety-filter refusal of its own permission check toward the consecutive-block limit; the action is still denied, but the model is now told to move on rather than retry
Fixed cross-session messages staying parked without a notice or expiry in headless sessions and during startup
Fixed conversation history breaking on Remote Control session resume after very large conversations were compacted
Fixed hovering over a session in another project in the agents list changing the directory the next agent starts in
Fixed claude self-hosted-runner registering and then failing every session when --base-dir cannot be created or written; it now exits at startup with a clear error
Fixed Claude Code on the web sessions being misreported as stuck, re-sending a growing event backlog on every reconnect
Improved Remote Control: photos attached from the Claude app are now shown to Claude directly instead of being read from disk with a separate tool call
[VSCode] Fixed Focus view folding away the latest to-do list, a pending question’s context, and settled answers; thinking-only folds show “Thought for Ns” and re-collapse when their turn completes
SendMessage can now start a conversation with your Remote Control sessions on other machines by name (ListAgents shows them as name [ref]), instead of only replying after they message you first
SendMessage: a Remote Control recipient you already confirmed is never swapped for a same-named session on this machine when its own list couldn’t be checked

2.1.224

Thu, 06 Aug 2026 16:00:00 GMT

Added self-hosted environments: claude self-hosted-runner turns your own machines or containers into a place Claude Code web, mobile, and desktop sessions can run, on Team and Enterprise plans
Added archive plugin source: install plugins from a zip over HTTPS without git or npm, with optional SHA-256 pinning
Added a cancel-and-confirm step when removing an unavailable paste changes a command’s text
Added ANTHROPIC_BEDROCK_REGION_PREFIX env var for Bedrock to prefer a specific cross-region inference profile over the AWS_REGION-derived one
Added crossSessionInbound and dialogExpiry settings: cross-session messages sent to a session running with bypassed permissions are held for your approval, and messages to other sessions auto-deliver
Added sandbox credential-masking options: extract and onExtractNoMatch for structured env values, decode: "jwt" with maskClaims for JWT-aware masking, and awsPairs/sigv4 for AWS SigV4 re-signing; these need network.tlsTerminate and are honored only from user, managed, or --settings settings
Added cross-session SendMessage: Claude Code sessions can now message each other, on any of your machines, with ListAgents to discover them (macOS and Linux)
Fixed long (>200 char) project paths resolving to another project’s session directory under a shared sanitized prefix; session list, rename, fork, delete and /resume no longer cross projects
Fixed SendMessage reporting “Message sent” when the write to a teammate’s inbox had actually failed; failed deliveries are now reported as errors
Fixed sandbox filesystem deny entries written with a trailing slash (e.g. denyRead: "~/.aws/") being silently bypassable on Linux and macOS
Fixed sandbox violation details never appearing in Bash tool results; Claude now sees which file or network access was denied and why
Fixed MCP tools that connect mid-turn being deferred for tool search without their names announced to the model
Fixed plugin install records being silently corrupted when the same plugin is installed in multiple projects
Fixed recalled or restored paste content occasionally attaching wrong data or silently losing text when the paste had aged out or placeholder numbers collided
Fixed copy-on-select on Wayland sometimes not reaching the clipboard; the two selection writes no longer race
Fixed the feedback survey’s transcript share silently failing on long sessions; a failed share now shows an error instead of a success message
Fixed Remote Control auto-start intermittently failing with “Remote credentials fetch failed” on a cold start with a stale login token
Fixed Remote Control and SDK clients showing a blank “(no content)” message after /clear and other output-less commands
Fixed a Remote Control session recreated after its server session expired uploading prior local conversation history into the new session
Improved fullscreen mode to keep the full pre-compaction history in scrollback across repeated compactions, instead of only the most recent interval
Improved Remote Control: attached web and mobile clients now see compaction progress and the post-compaction boundary instead of a silent pause; /clear resets now propagate to attached clients
Improved Remote Control: connection failures now show a persistent failure indicator with details and a reconnect shortcut, instead of only an 8-second toast
Removed the 200-subagent-per-session spawn cap; long-running sessions no longer refuse new agents (concurrency and depth limits still apply)
Changed managed settings: the approval prompt no longer re-appears after re-login or org switching when the organization’s settings are unchanged
Changed the feedback-survey transcript share: with your consent it now also uploads the last request’s model settings — the system prompt (which includes your CLAUDE.md instructions), tool definitions, and model parameters. Secrets are redacted as before, and these fields are dropped first if the share is too large
Changed the Bash tool description to always note that command output is displayed to the model, not reliably to the user
Changed recalled paste placeholder numbers to renumber when accepted into the input
Changed Remote Control to archive the stale server session instead of leaving a dead one listed when a fresh session is minted after compaction or /resume
[VSCode] Fixed the extension showing Remote Control as connected after the connection failed
Fixed a session resume silently reconnecting Remote Control after the user turned it off (--resume, SDK hosts, and the VS Code extension)
[VSCode] Fixed sessions not honoring remoteControlAtStartup when explicitly enabled

2.1.223

Wed, 05 Aug 2026 16:00:00 GMT

Added owner wildcard entries ("owner/*") to the strictKnownMarketplaces and blockedMarketplaces managed settings for allowing or blocking all marketplace repos under a GitHub org
Added a warning when workflow agents, forked skills, slash commands, or resumed background agents’ requested subagent model is restricted and the parent model runs instead
Added a /teleport hint in cloud sessions showing how to continue locally with claude --teleport <session id>
Fixed a Bash permission bypass where a crafted command could hide parts of itself from permission checks
Fixed permission prompts so commands padded with tabs or invisible Unicode can no longer hide part of the command from the approval dialog
Fixed workflow scripts being able to use dynamic import() to run code outside the workflow sandbox
Fixed a permission gap where an agent definition’s bypassPermissions mode ignored the org bypass-permissions disable policy
Fixed resuming a session after a mid-session /cd coming back empty
Fixed gateway model discovery hiding Claude models registered under provider-prefixed IDs such as vertex_ai/claude-* or bedrock/anthropic.claude-*
Fixed modelOverrides keys that aren’t Anthropic model IDs being treated as the session’s canonical model ID; unknown keys are now ignored as documented
Fixed managed settings: server-delivered settings no longer disable the env block of a machine-local managed-settings.json or MDM profile; admin env now merges per key
Fixed sandboxed commands failing to start on Linux when sandbox.filesystem.denyWrite covers the working directory
Fixed forked background agents getting stuck “already resuming” for the rest of the session when rebuilding the fork’s parent prompt failed during resume
Fixed a resumed session failing every turn, or leaving the interactive app on an unresponsive error screen, when its history held a malformed diagnostics attachment
Fixed a rare hang when parsing unusual git push output
Changed CLAUDE_CODE_DISABLE_1M_CONTEXT to hold every Claude model with a native 1M window to 200K via auto-compaction, not just a fixed list; a startup warning now appears when auto-compaction isn’t holding the session to 200K
Changed auto-compact to keep sessions on unrecognized model IDs within the assumed context window instead of letting them grow past it; set CLAUDE_CODE_DISABLE_UNKNOWN_MODEL_WINDOW_ENFORCEMENT=1 to restore the previous behavior
Changed /review to be an alias of /code-review, which reviews the current diff or a PR (/code-review <level> <pr#>); use /code-review ultra for a deep cloud review
Changed /code-review with no effort level to reuse the level you typed last; type a level like /code-review high to change it

2.1.222

Mon, 03 Aug 2026 16:00:00 GMT

Fixed worktree-isolated sessions and their subagents being able to run destructive git commands against the main checkout; isolation now applies to file edits and Bash in every session type
Fixed PreToolUse auto-allow hooks bypassing tool restrictions in background agent tasks (summaries, compaction, renames)
Fixed /usage-credits on Team and Enterprise showing “you’ve already sent a usage credit request” for members whose earlier request was dismissed, blocking them from sending a new one
Fixed the startup connectivity check hanging and then failing behind an HTTPS proxy; it now uses the same proxy-aware transport as API requests and times out with a clear message
Fixed “Connection closed mid-response” errors being reported on responses that had actually completed
Fixed /usage overattributing usage to MCP servers: a server’s share now reflects only the requests that actually consumed its tool results, instead of every turn after any call to it
Fixed sessions not linking to pull requests created after the branch was pushed, including through the GitHub REST API
Fixed org-restricted model: opus-style subagent and teammate family aliases dropping to the parent model instead of stepping down to the newest org-allowed model in the family
Fixed stream idle timeout firing on custom ANTHROPIC_BASE_URL gateways despite server keep-alive pings arriving on the wire
Fixed claude.ai connectors being falsely marked as needing authorization when the session token is invalid — they now show a /login hint instead
Fixed tool errors not being displayed for tools no longer available locally, for example after an MCP server is removed
Fixed SendMessage rejecting a long summary — it now truncates instead, so sends no longer fail on a character limit
Fixed the spinner’s effort label in a subagent’s transcript view showing the session’s effort level instead of the subagent’s own effort: setting
Fixed rare crashes when a file watcher hit a filesystem error or during file-watcher teardown
Fixed screen readers re-reading the whole input line on every backspace in --ax-screen-reader mode — end-of-line deletions now echo just the deleted characters
Fixed host model-selection keys not taking precedence over a stale on-disk managed-settings.json when CLAUDE_CODE_PROVIDER_MANAGED_BY_HOST is set
Improved auto mode safety: messages sent to other agent sessions via SendMessage are now evaluated by the permission classifier before dispatch
Improved the refusal when Claude tries to invoke a skill with disable-model-invocation: Claude is now told to ask you to run the skill instead of replicating its workflow
Improved the /diff view, the Remote Control workspace diff, and file-edit diffs in Claude Code on the web sessions to use raw git blob content, ignoring workspace-configured diff drivers and textconv
Changed Remote Control auto-start so repo-local settings (.claude/settings.json or .claude/settings.local.json) can no longer turn it on (they can still turn it off); enable it at user scope via /config
Removed ultraplan feature

2.1.221

Mon, 03 Aug 2026 16:00:00 GMT

[VSCode] Added Focus view: a chat-menu toggle that hides tool activity behind an expandable per-turn summary with a live running-tool indicator, toggled with Ctrl+Alt+F or the “Claude Code: Toggle Focus view” command
Added mode: "mask" for sandbox credential files on Linux and WSL — sandboxed commands read a sentinel copy (the whole file, or just the spans captured by an extract regex) while the sandbox proxy substitutes the real value on egress; on macOS file masking falls back to deny
Added warnings to claude plugin validate when a marketplace or plugin name would be rejected by Claude Desktop’s managed marketplace sync
Added a prompt-audit subcommand to the claude-api skill for auditing prompts and tool descriptions for patterns written for older models
Fixed a Bash tool permission-check bypass where zsh could execute hidden commands in [[ ]] regex conditionals; affected commands now prompt for permission
Fixed PowerShell permission checks mishandling paths containing quote characters on Windows; such paths now prompt for approval
Fixed the thinking toggle having no effect for the rest of a session that started with thinking off; disabling an MCP server mid-connect no longer silently reverts
Fixed MCP servers from --mcp-config not being connected before the first turn in print mode (-p), which made the model emit tool calls as literal text
Fixed @-mentioned files being silently dropped when pressing Esc to retract a prompt and resubmitting it
Fixed a crash when preparing API requests for SDK MCP tools named after built-in object properties such as constructor
Fixed WebSearch failing with a 400 error at effort xhigh/max when thinking is disabled
Fixed sandboxed large uploads failing with TLS errors through the sandbox proxy
Fixed Team and Enterprise spend-limit message incorrectly blaming the org’s monthly limit instead of your individual spend limit
Fixed Bedrock authentication with AWS SSO named profiles failing in desktop-managed sessions on Windows machines that set a stray HOME environment variable
Fixed CLAUDE_CODE_RESUME_INTERRUPTED_TURN=0 not disabling interrupted-turn auto-resume; falsy values are now honored
Fixed a rare wake-from-sleep race where two Claude Code processes could both refresh the same MCP connector or WIF OAuth token at once, forcing re-authentication
Fixed renaming a session from Claude Code Desktop or claude.ai not updating the CLI’s session name; session names from every rename surface are now sanitized
Fixed plugin- and org-delivered skills named after terminal-only built-ins (e.g. /help, /feedback) being un-invocable in non-interactive sessions
Fixed the “Plugins changed” notification lingering after plugins were reloaded instead of clearing
Fixed Vim mode: the yank register now survives dialogs, history search, and the transcript view instead of being silently emptied
Fixed Vim mode: undoing back to an empty prompt now arms the “press ← again” confirm before returning to the agent view
Improved tool search on Google Vertex AI: re-enabled for Claude 4.5-generation and newer models
Improved auto mode: permission checks for parallel tool calls are now cache-efficient, and switching modes while a check is pending reliably prompts instead of applying the stale result
Reduced prompt-cache costs for auto-mode permission checks by reusing the cached conversation prefix across decisions
Improved Stats panel to count cache tokens in its token totals, with a breakdown by input, output, cache read, and cache write
Improved /ultrareview error messages when a repo shares no history with its base: a checkout with no branches is now refused up front with advice to create one, and refusal hints no longer suggest git fetch --unshallow on clones that are already complete
Improved Windows startup: process creation times are now read via a native kernel32 call instead of spawning PowerShell, so endpoint security tools that gate powershell.exe no longer prompt
Changed background sessions to commit and push to preserve work, open a draft PR only when the task calls for one, follow your CLAUDE.md git instructions, and always end by reporting where the work lives
Changed /plugin install to refresh a stale marketplace catalog and retry before reporting a plugin not found
Changed plugins installed from /plugin to activate immediately when safe, instead of always requiring /reload-plugins
Changed plugins to accept "." as a skills path, and the root-level SKILL.md validation error now suggests using the plugin root
Changed /status to show the session kind: interactive, or a background job that is attached or unattended
Changed emoji autocomplete to accept common alternate shortcodes like :thumbsup:, :thumbsdown:, and :love:
Changed sessions forked with /fork to create a new worktree of their own instead of working in the original session’s checkout
Changed Claude in Chrome to close the browser tabs it opens once it no longer needs them
Changed fast mode to report on the stream when usage credits run out mid-session, instead of failing silently
Changed Monitor: a watch that exits without producing any output now says so instead of reporting “stream ended”
Changed the Gateway model field validation: non-string values are rejected with a 400 instead of being forwarded
Removed the repeated “Permission mode changed while the auto-mode classifier call was queued” notice from approval prompts

2.1.220

Fri, 24 Jul 2026 16:00:00 GMT

Bug fixes and reliability improvements

2.1.219

Thu, 23 Jul 2026 16:00:00 GMT

Added Claude Opus 5 (claude-opus-5), now the default Opus model — 1M context, fast mode at $10/$ 50 per Mtok
Added sandbox.network.strictAllowlist setting to deny non-allowlisted hosts for sandboxed commands without prompting
Added DirectoryAdded hook that fires after /add-dir or the SDK register_repo_root control request registers a new working directory mid-session
Added mcp_server_errors to the headless stream-json init event, listing --mcp-config entries skipped by config validation; terminal runs print a startup warning
Added the workflowSizeGuideline settings key so the advisory Dynamic workflow size guideline can be set from any settings file; the /config row is hidden while one does
Added nested subagent forwarding in stream-json: subagents spawned at depth-2+ now appear when --forward-subagent-text is set, keyed by their spawning Agent tool_use id
Fixed claude -p text output dropping the answer already produced when a turn dies on a mid-stream API error
Added HTTP status and error text to claude mcp list and /mcp when a server fails to connect, and a warning for MCP config values with hidden leading or trailing whitespace
Fixed the Fable model row showing “Requires usage credits” for plans that include it, when a stale cache had baked the label in
Fixed the /model picker showing the merged Opus row as plain “Opus” instead of “Opus (1M context)”
Fixed copy-on-select inside GNU screen printing base64 into the terminal instead of copying the selection
Fixed Remote Control clients keeping a stale fast-mode status after a model switch, reconnect, or failed org check
Fixed CLAUDE_CODE_GIT_BASH_PATH on Windows exiting or being used as bash when the path isn’t a bash/sh binary; it’s now ignored with a warning
Fixed Vim mode: pressing ← on an empty prompt now returns to the agent view from NORMAL mode, not just INSERT
Fixed screen-reader mode rewriting the entire input line on every keystroke instead of echoing only the typed character
Improved the “Remote Control is only available via api.anthropic.com” error to name the specific setting that caused it
Improved claude --teleport to show which repo your current checkout points at when it doesn’t match the session’s repo
Changed dynamic workflows to default to a medium size guideline (aim for fewer than 15 agents); pick another size or unrestricted with Dynamic workflow size in /config
Changed managed MCP allowlist/denylist ${VAR} entries to resolve from the startup environment and managed-settings env instead of settings-file env
Changed the /model picker to highlight only the newest model’s name, so the highlight marks the new release rather than an arbitrary subset of the list
Added the current default workflow size to the running-workflow status line, with a pointer to /config for changing it
Removed Opus 4.7 from fast mode; /fast now applies to Opus 5 and Opus 4.8
Updated the claude-api skill to default to Claude Opus 5, with a migration path from Opus 4.8
Subagents can now spawn nested subagents up to depth 3 by default (was 1); set CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH=1 to disable nesting

2.1.218

Tue, 21 Jul 2026 16:00:00 GMT

Changed /code-review to run as a background subagent, so review work no longer fills your conversation and keeps stacked slash commands as its review target
Added screen-reader announcements of deleted text for word and line deletions (Option+Delete, Ctrl+W, Cmd+Backspace, Ctrl+U, Ctrl+K) in --ax-screen-reader mode
Fixed Windows paths with \u-prefixed segments (like C:\Users\unicorn) being corrupted into CJK characters in tool inputs, which made those files inaccessible
Fixed the left arrow key discarding the conversation with no undo: presses right after editing now ask to confirm, and Esc in the agent view returns to the conversation it backgrounded
Fixed multi-line paste collapsing into one line with j in place of newlines in terminals that encode pasted newlines as Ctrl+J
Fixed /context reporting stale pre-compact token usage after compacting from the message picker
Fixed /ultrareview failing on descriptive arguments like “review my auth changes” — they now run a review of your current branch with the text applied as a note to the findings
Fixed /code-review ultra silently running a local review in non-interactive sessions — it now launches the cloud review
Fixed gateway spend metering to price Bedrock application-inference-profile ARNs and other config-mapped upstream model IDs at the configured model’s rates
Fixed mojibake when a long IDE selection was truncated mid-emoji, and a case where a tool executor error could be silently dropped
Fixed an engine teardown race that could start and abandon a phantom turn, and made input pushed after close consistently rejected
Fixed spurious “[Request interrupted by user]” messages after interrupted tool calls, and an unpaired tool_use block left in the transcript when a tool aborted mid-response
Fixed VoiceOver reading “new line” instead of echoing the typed space at the end of the input in --ax-screen-reader mode
Fixed plugin and settings panels not moving the terminal cursor to the focused row, so screen readers and magnifiers can follow arrow-key navigation
Fixed crashes (maximum call stack exceeded) when a deeply nested watched directory tree was deleted or moved, and when rendering deeply nested UI trees
Fixed pull request events occasionally being lost when a session exited immediately after creating or linking a PR
Fixed the Bedrock setup wizard failing profile verification for assume-role profiles in partitioned AWS regions and on proxy-only networks
Fixed rare negative or incorrect turn duration measurements after a system clock adjustment by timing turns with a monotonic clock
Fixed the “N MCP servers need authentication” startup notice over-counting claude.ai connectors that aren’t connected in claude.ai
Fixed prompt history entries being dropped or duplicated when history writes raced or failed
Fixed a retry loop that re-sent identical doomed requests after a context-overflow error with a large thinking budget; Ctrl+B backgrounding now applies the same background-shell caps as other paths
Fixed agent frontmatter hooks running from untrusted folders: hooks now require the agent file’s own folder to have accepted workspace trust
Fixed fork-session lineage being lost after compaction in headless and SDK sessions
Fixed a resumed session failing every turn, or crashing on resume, when its history held a malformed delta attachment
Improved /ultrareview error feedback so Claude can correct an invalid argument instead of retrying it unchanged
Improved auto mode: the dangerous-rm, background-&, and suspicious-Windows-path checks no longer open permission dialogs; the auto-mode classifier adjudicates them instead
Improved sandbox command restrictions for IDE interactions
Improved trust dialogs to name the repository root the grant covers
Changed /deep-research to start only when invoked manually; Claude no longer launches it on its own
Changed plan mode with auto to no longer prompt for Bash commands the static analyzer can’t prove read-only; the auto-mode classifier judges them instead
Added an announcement when fast mode changes as a result of switching models via /config model=<x> or Remote Control
Changed server-managed settings so benign feature and cost toggles no longer trigger the settings-approval prompt
Changed agent markdown files to reject agent names containing :, which is reserved for plugin namespacing
Changed skills with context: fork to run in the background by default; opt out per skill with background: false
Added yes/no/on/off/1/0 (case-insensitive) as accepted values for skill and plugin frontmatter booleans, alongside true/false
Fixed remote sessions continuing to send heartbeats after their worker was replaced, which left long-lived desktop and IDE processes retrying a rejected request every few seconds forever

2.1.217

Mon, 20 Jul 2026 16:00:00 GMT

Added emoji shortcode autocomplete in the prompt input: type :heart: to insert ❤️, or :hea for suggestions — disable with the emojiCompletionEnabled setting
Added warnings when transcript writes are failing (e.g. disk full) or when session saving is off due to an inherited environment variable, instead of losing transcripts silently
Fixed a memory leak where truncated MCP tool outputs kept the full untruncated result in memory for the rest of the session
Fixed Windows auto-update failures that could leave claude.exe missing; failed updates now restore the preserved executable automatically
Fixed background session isolation not canonicalizing symlinked working directories, which could let sessions escape their workspace folder
Fixed auto-compact never triggering for Claude Opus 4.8 on Bedrock and /compact failing once over the limit
Fixed corporate mTLS, TLS-verify, OAuth scope, and proxy settings being ignored in Claude Desktop sessions
Fixed screen reader mode’s startup announcement being cut off by the first prompt render, and the thinking status row re-rendering every few seconds to update elapsed time and token counts
Fixed managed settings that set OTEL_EXPORTER_OTLP_ENDPOINT not governing all signals — lower-scope signal-specific overrides no longer redirect telemetry away from the managed endpoint
Fixed --resume/--continue and /resume failing with a TypeError when a transcript has a malformed attachment entry
Fixed Remote Control sessions not showing a pending permission prompt or dialog to viewers that connected after it appeared
Fixed background shells sometimes becoming impossible to stop after a session is sent to the background (/background or ←) or when the session exits on a heavily loaded machine, most visible on Windows
Fixed a CLAUDE.md or SKILL.md paths frontmatter value with many brace groups OOM-killing or stalling the CLI at startup — brace expansion is now budget-bounded
Fixed the transcript preview sitting flush against the input area when attaching to a starting background session; it now leaves the same one-line gap as the live layout, so the transcript no longer shifts when the session takes over
Improved footer PR badge links to be clickable hyperlinks even when terminal support can’t be detected (e.g. over ssh/tmux); set FORCE_HYPERLINK=0 to opt out
Changed the login-expiry warning to appear 3 days before expiry instead of 5
Capped the frontend-design plugin suggestion tip at 3 lifetime impressions instead of repeating indefinitely
Added a cap on concurrently-running subagents (default 20, override with CLAUDE_CODE_MAX_CONCURRENT_SUBAGENTS) so one message can’t fan out unbounded background agents
Changed subagents to no longer spawn nested subagents by default; set CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH to allow deeper nesting
Fixed --max-budget-usd not stopping background subagents: once the cap is reached, new spawns are denied and running background agents are halted

2.1.216

Sun, 19 Jul 2026 16:00:00 GMT

Added sandbox.filesystem.disabled setting to skip filesystem isolation while keeping network egress control
Fixed a slowdown in long sessions where message normalization cost grew quadratically with the number of turns, causing multi-second stalls and slow resumes
Fixed auto mode denying commands with “HTTP 401” classifier errors after the OAuth token expired or rotated mid-session
Fixed AskUserQuestion telling Claude to continue even when your answer asked it to wait or explain first — free-text answers now get neutral wording
Fixed Claude Code on the web re-asking the same question and dropping your answer after the session sat idle for a few minutes
Fixed @-mentions silently attaching nothing after file-modifying hooks, vim dot-repeat of c-operators and paste, statusline running twice on resume, and resume-picker hangs on failure
Fixed resumed background agent sessions reverting to the default agent: the agent’s prompt and tool restrictions are now restored
Fixed worktree-isolated subagents redirecting git into the shared checkout via git -C, --git-dir, or GIT_DIR/GIT_WORK_TREE
Fixed worktree sessions landing in another project’s leftover worktree when the working directory did not match the selected project
Fixed background sessions whose worktree has no git repository being undeletable
Fixed claude daemon stop --any potentially terminating an unrelated process via a stale legacy daemon lockfile
Fixed Esc-Esc at an idle prompt not opening the rewind picker in long-running sessions with background tasks
Fixed Bash command permission checking for compound statements with redirects inside && lists or negations
Fixed pressing Ctrl+X twice in the agent list failing to delete a session, and deleted sessions reappearing when their background worker had died
Fixed background subagents getting cancelled when a high-priority message arrives during their startup window
Fixed mouse and focus garbage in the terminal while a GUI editor from /memory, /plan, /keybindings, or Ctrl+G is open; /memory no longer waits for the editor to close
Fixed Claude-in-Chrome 403-looping on reconnect when the session’s OAuth token lacks a required scope
Fixed workflow saves and scheduled-task writes following a symlink at .claude, which could redirect writes outside the project
Fixed MCP re-authenticate revoking working credentials before the new sign-in succeeds, and the reconnect needs-auth message in background sessions pointing at an unusable command
Fixed read-only commands on Windows accessing network paths without a permission prompt
Fixed Bash command parsing of non-ASCII characters to match real shell word boundaries
Fixed PowerShell tool permission validation of commands containing invisible Unicode characters
Fixed dialogs in fullscreen mode stretching past the right-hand edge of their panel
Fixed the /config settings list in fullscreen mode clipping its keyboard-hint footer
Fixed the transcript-mode (Ctrl+O) footer hint wrapping on terminals narrower than 104 columns
Fixed the Prometheus metrics endpoint (OTEL_METRICS_EXPORTER=prometheus) emitting invalid # UNIT lines
Fixed skills and commands changed during a session not appearing in the slash menu until restart
Fixed plugin skills with a name frontmatter field losing their plugin prefix in slash-command autocomplete
Fixed telemetry misreporting permission denials: failed permission-prompt requests no longer count as user rejections, and user interrupts are now reported as user aborts instead of rejections
Improved the /fork confirmation to one line with the new session’s name, claude attach id, and a note when the copy shares your checkout
Improved validation of git and gh command arguments in the PowerShell tool
Improved the /ultrareview diff-too-large error to show configured limits, measured diff size, and largest contributing files
Improved /code-review ultra empty-diff message to name the exact base ref and suggest passing an explicit base
Improved the spend limit adjustment prompt to show the server’s reason when a spend limit change is rejected
/context now shows an explicit warning when the conversation exceeds the context window, and a failed /compact displays as an error
/rewind no longer restores or deletes files through symlinks or hard links at tracked paths and reports how many paths it skipped
Background sessions: /mcp and /install-github-app now park a “needs input” request in the agent view when no client is attached
Updated the bundled dataviz skill: reordered the default chart palette and fixed guidance that suggested direct labels for four-series charts
[VSCode] Fixed right-to-left text (Arabic, Hebrew, Persian) rendering in the wrong order when mixed with English or code
Fixed cloud sessions dropping the in-flight message when the session’s container restarts mid-turn — the interrupted turn now re-runs on resume instead of leaving the session unresponsive

2.1.215

Sat, 18 Jul 2026 16:00:00 GMT

Claude no longer runs the /verify and /code-review skills on its own; invoke them with /verify or /code-review when you want them

2.1.214

Fri, 17 Jul 2026 16:00:00 GMT

Fixed single-segment dir/** allow rules like Edit(src/**) auto-approving writes to nested dir/ directories anywhere in the tree instead of only <cwd>/dir
Fixed a permission-check bypass affecting commands run in Windows PowerShell 5.1 sessions
Fixed Bash permission checks to fail closed on file-descriptor redirect forms that bash parses differently than the permission analyzer
Fixed Bash permission checks misjudging very long commands — commands over 10,000 characters now always prompt instead of running automatically
Fixed Bash permission checks treating zsh variable subscripts and modifiers in [[ ]] comparisons as inert text — these commands now prompt for approval
Fixed Bash permission checks to no longer auto-approve certain help and man commands that could run unsafe options, command substitutions, or backslash paths
Fixed permission prompts on remote sessions that could proceed before the local confirmation dialog
Added the EndConversation tool: Claude can end sessions with highly abusive users or jailbreak attempts, as on claude.ai since 2025 — see https://www.anthropic.com/research/end-subset-conversations
Added a periodic progress heartbeat for long-running tool calls that previously went silent
Added an ISO modified timestamp to memory file frontmatter
Added message.uuid, client_request_id, and tool_source attributes to OpenTelemetry log events for message-level correlation and tool provenance
Added CLAUDE_CODE_OTEL_CONTENT_MAX_LENGTH to configure the 60 KB truncation limit on OpenTelemetry content attributes
Added reasoning effort to the subagentStatusLine payload, so custom agent rows can render model and effort
Added permission prompts for docker commands (including the Podman docker shim) carrying daemon-redirect flags (--url, --connection, --identity, and Podman’s remote mode) that previously ran without one
Fixed a crash when a GrowthBook feature evaluates to null, and a bug where a malformed flag payload could wipe the cached feature flags
Fixed Bash tool killing the Claude session when a pkill -f pattern accidentally matched the CLI’s own process (Linux)
Fixed unbounded memory growth when --settings points at a device file or multi-GB file; oversized (>2 MiB) settings files now fail at startup with a clear error
Fixed streaming turns failing with “Socket is closed” behind corporate proxies on Windows
Fixed stream-json output truncation at exit for slow-reading SDK/pipeline consumers; the exit drain now scales with queued bytes instead of a flat 2s cap
Fixed scheduled tasks refusing their own configured prompt as untrusted input — the fired prompt is now delivered as the session’s assigned task

2.1.212

Thu, 16 Jul 2026 16:00:00 GMT

/fork now copies your conversation into a new background session (its own row in claude agents) while you keep working; the in-session subagent it used to launch is now /subtask
Added claude auto-mode reset to restore the default auto-mode configuration, with a confirmation prompt (pass --yes to skip)
Added a session-wide limit on WebSearch tool calls (default 200, tunable via CLAUDE_CODE_MAX_WEB_SEARCHES_PER_SESSION) to stop runaway search loops
Added a per-session cap on subagent spawns (default 200, override with CLAUDE_CODE_MAX_SUBAGENTS_PER_SESSION) to stop runaway delegation loops; /clear resets the budget
MCP tool calls running longer than 2 minutes now move to the background automatically so the session stays usable; configure the threshold or disable with CLAUDE_CODE_MCP_AUTO_BACKGROUND_MS

Fixed plan mode auto-running file-modifying Bash commands (e.g. touch, rm) without a permission prompt or SDK canUseTool callback
Fixed worktree creation following a repository-committed symlink at .claude/worktrees, which could create files outside the repository
Fixed a continue:false hook’s halt being dropped when the tool fails or completes mid-stream, and hook infrastructure errors being misreported as user rejections
Fixed SIGTERM during a running Bash tool orphaning the command’s process tree in print/SDK mode; the CLI now aborts the turn, kills the tree, and exits 143
Fixed /background and claude --bg failing with “EUNKNOWN: unknown error, uv_spawn” on Windows when Group Policy blocks PowerShell 5.1; the daemon now prefers PowerShell 7
Fixed shell mode (!) not executing commands containing file paths while the path autocomplete popup was open
Fixed auto-mode denial notifications rendering broken characters when a long denial reason was truncated mid-emoji
Fixed Ctrl+J not inserting a newline in the agent view dispatch input on terminals with extended key reporting, and surfaced the newline shortcut in the ? help overlay
Fixed /ultrareview rejecting PR references like #123, PR 123, and pasted PR URLs; error hints now name the command you actually typed
Fixed /ultrareview <branch> not fetching the branch from origin when it exists remotely; it now suggests the closest branch name on typos
Fixed /ultrareview skipping the billing confirmation in a new conversation after /clear
Fixed /ultrareview’s “not a git repository” error on Claude Desktop now suggesting the project’s repository folder instead of terminal commands
Fixed hosted (host-managed) sessions failing at startup when repository settings configured mTLS certs, extra CA bundles, or OAuth scopes; these transport settings are now ignored with a warning

Fixed web search and web fetch returning “API Error” text as search results or page content when the API was overloaded
Improved web search and web fetch reliability by retrying 529 errors and rate-limited requests with bounded backoff
Improved prompt caching: the mid-conversation system block now works behind LLM gateways and custom base URLs (Bedrock, Vertex, 1P)
Improved background agent attach: cold-attaching now instantly shows the formatted transcript while the session boots, instead of a blank wait
Reduced token usage in inter-agent messaging: SendMessage bodies are no longer duplicated into replayed history and tool results
Changed /fork to name the copy after your prompt when the session has no title, so the row is recognizable in the agent view
Changed bare /btw to reopen the side-question panel on your most recent exchange so you can browse earlier answers
Changed the ← footer hint to pulse N done for a moment when a background agent finishes while nothing needs your input
Deprecated the Task tool’s mode parameter (now ignored); subagents inherit the parent session’s permission mode by default
Changed Enterprise forceLoginMethod to be enforced for VS Code extension, SDK, setup-token, and install-github-app logins, not just the terminal
Changed session transcripts to record the reasoning effort level on each assistant message
Changed headless/SDK sessions to apply a set_model control request mid-turn; the next model round-trip uses the new model instead of waiting for the next turn
Changed agent view / claude agents --json: sessions waiting on a sandbox, MCP-input, or managed-settings prompt now show as “Needs input” instead of “Working”
Updated the auth status panel title from “Cloud authentication” to “Authentication”
Corrected an earlier release note (2.1.200): tmux through the 3.6 series lacks synchronized output; newer tmux with support is detected automatically

Added --forward-subagent-text flag and CLAUDE_CODE_FORWARD_SUBAGENT_TEXT environment variable to include subagent text and thinking in stream-json output
Fixed permission previews relayed to chat channels not neutralizing bidirectional-override, zero-width, and look-alike quote characters, so tool inputs cannot visually alter the approval message

Updated integer environment variables (timeouts, token budgets, retry counts) to accept scientific notation and digit-separator spellings like 1e6 and 64_000
Updated documentation links to the current docs sites
Changed “always allow” permission rules to save at the repository root, so approvals granted in a git worktree persist across sessions and worktrees

Changed Vim mode s and S (substitute char/line) to work in NORMAL mode, matching vim behavior
[VSCode] Updated the Remote Control banner to describe what it does
Claude in Chrome: hardened file-upload path validation
Claude in Chrome: save_to_disk on screenshot actions now writes the image to disk and returns the path; previously it did nothing
Fixed a prompt-caching regression on Bedrock, Vertex, Mantle, and Foundry that billed the trailing system context block as fresh input tokens on every request.

2.1.210

Mon, 13 Jul 2026 16:00:00 GMT

Added a live elapsed-time counter to the collapsed tool summary line so long-running tool calls visibly tick instead of looking stuck
Added a startup warning for Write(path), NotebookEdit(path), and Glob(path) permission rules — use Edit(path) or Read(path) instead
Fixed isolation: 'worktree' subagents being able to run git-mutating commands against the main repo checkout instead of their own isolated worktree
Fixed the ultracode keyword opt-in firing on non-human-originated input such as webhook payloads and relayed PR comments
Fixed a rendered text fragment leaking into crash telemetry when a UI component returned content outside a styled text element
Fixed paste markers leaking into external editors opened from Claude Code, which could appear as stray È/É characters around pasted text
Fixed claude attach sometimes failing with “job not found” or “agent is still starting” errors during session transitions — attach now waits for the daemon to settle, and terminal resizes during a slow attach are applied once it completes
Fixed a session crash when a tool’s result renderer returned a numeric bigint value or plain text instead of a UI element
Fixed a hook callback timeout being misreported to the model as a user rejection, which made unattended sessions stop and wait
Fixed Claude assuming a cd took effect after its command was moved to the background; the tool result now states the working directory is unchanged
Fixed plugin-provided MCP servers being torn down when MCP servers are re-synced mid-session
Fixed plan approvals without edits being labeled “(edited by user)” and overwriting the plan file with a stale snapshot
Fixed /doctor skipping its auto-mode-default proposal on Bedrock, Vertex, and Foundry, where auto mode no longer needs an opt-in
Fixed Grep content mode claiming “No matches found” when paginating past the end of results
Fixed unmatched $1/$2 positional placeholders in skills and commands being silently stripped; they are now preserved verbatim

Fixed claude agents --effort ultracode not reaching dispatched sessions; the value was silently dropped
Fixed pressing ← to open the agents view dropping the task tracker when returning to the session
Fixed the agents dashboard retaining pasted images from abandoned reply drafts after their session was deleted
Fixed killed background sessions leaving a permanent git worktree lock behind; the periodic sweep now releases locks whose owning process is gone

Fixed returning to the agents view from a session leaving overlapping ghost frames with CLAUDE_CODE_DISABLE_ALTERNATE_SCREEN=1
Fixed late-appearing .claude/* symlinks not being reconciled into the sandbox deny-write list
Hardened the Agent tool against indirect prompt injection via content a subagent read
Improved the Bash/PowerShell tool message when a command hits its timeout and is auto-backgrounded, so the model can distinguish a hang from an explicit background request

Improved the bundled dataviz skill’s chart color validation with perceptual OKLab color difference and recalibrated color-blindness thresholds
Memory writes that leave a MEMORY.md index over its read limit now produce an explicit error instead of silent truncation

Fixed /model and other dialogs being blocked in claude agents background sessions (reverts an overly broad guard)

2.1.208

Mon, 13 Jul 2026 16:00:00 GMT

Added screen reader mode: opt-in plain-text rendering for screen reader users. Run claude --ax-screen-reader, set CLAUDE_AX_SCREEN_READER=1, or add “axScreenReader”: true to settings.
Added vimInsertModeRemaps setting: map two-key insert-mode sequences like jj to Escape in vim mode
Added CLAUDE_CODE_PROCESS_WRAPPER: agent view and the background service now honor a corporate launcher by running every Claude Code self-spawn through a required wrapper executable
Added mouse-click support for multi-select menus and “Other” input rows in fullscreen mode
Changed the Fable 5 usage-credits consent prompt to start with the decline option focused
Fixed fast mode staying off after switching back to a model that supports it — it now restores automatically when enabled in settings
Fixed replies typed to a background agent being lost when delivery fails — the text is now saved and delivered when the session restarts
Fixed background-session attach failing permanently (“Couldn’t start the background daemon”) after an update replaced the binary a running claude agents process was launched from
Fixed the context window (and auto-compact indicator) briefly resetting to 200k after the CLI auto-updates, causing a false “100% context used” when resuming long-context sessions

Fixed the Edit tool failing on files modified after reading when the target text still matches uniquely
Fixed Read reporting empty files as “shorter than offset”, Grep silently returning “No files found” for invalid regex patterns, Grep count mode under-reporting totals when paginated, and Glob crashing with an unclear error when the pattern, path, or working directory contained a null byte
Fixed apiKeyHelper script failures being hidden behind a generic 401 after ~10 silent retries; the script’s own error is now shown within 3 attempts
Fixed Bedrock streaming requests failing with a misleading “Truncated event message received” when a gateway transforms the response — the error now names the content-type and points at the proxy
Fixed /upgrade showing a login flow instead of the upgrade URL when the browser fails to open
Fixed stream-json input killing the session on blank CRLF or whitespace-only lines from Windows-style SDK hosts
Fixed headless stream-json sessions hanging permanently when a control_request carried a non-string set_model payload; the CLI now answers with an error response
Fixed repeated “No completion record was found” notices on session resume — orphaned background tasks now collapse into a single summary
Fixed Remote Control clients attaching to a terminal-hosted session not seeing background agents and workflow progress until a task started or stopped
Fixed the Agent tool launching with no tools when a subagent’s tools list resolves to nothing — it now returns a clear error naming the unrecognized entries

Fixed “Change directory” in SDK hosts (e.g. Claude Desktop) failing with “A turn is in progress” on idle sessions that have a running background task
Fixed the workflow save dialog showing ~/.claude/workflows/ instead of the CLAUDE_CONFIG_DIR location for user-scope saves

Fixed a memory leak in the agent view where pasted images were retained for the screen’s lifetime after sending peek replies
Fixed SDK sessions losing agents defined via the initialize request when a plugin refresh ran before the client attached
Fixed several memory leaks in long sessions: MCP stdio server stderr accumulating up to 64 MB per server, LSP documents staying open indefinitely (now LRU with 50-doc cap), async hook output retained after backgrounding, and unbounded growth in headless/SDK sessions from large tool-result payloads
Fixed a memory blowup when reading files with extremely long single lines using offset/limit — the read now returns a clean error instead of loading the whole line
Fixed multi-second per-turn slowdowns in sessions with many permission deny/ask rules — rule matchers are now compiled once and cached
Improved input responsiveness while agent task lists update — task updates no longer re-render the entire UI
Reduced per-tool-call CPU overhead in print/SDK sessions with many MCP tools by caching tool-pool assembly (up to 7x faster tool rounds at high tool counts)
Reduced memory usage by bounding the file edit read cache to 16 MB instead of pinning up to 1,000 full files
Reduced session transcript size (up to 79x in edit-heavy sessions) and bounded checkpoint disk usage by pruning superseded file-history backups
Reduced memory usage when resuming sessions with background agents or forks spawned from large conversations
Completed background agents now stay listed in /tasks until cleanup instead of vanishing the moment they finish
Attaching to a stopped background agent now shows its transcript immediately while the session warms up, instead of a blank “Session is starting” screen
Background sessions: an older daemon no longer silently restarts workers spawned by a newer version onto the older binary
Agent view: Ctrl+X now deletes renamed-branch worktrees, never destroys unpushed commits, keeps the session row when a worktree is kept, and reused worktree names reset to the current base
Catastrophic removals (e.g. rm -rf ~) in commands containing $(…)/backticks/<(…) now prompt in --dangerously-skip-permissions and auto mode, matching the plain form
/install-github-app and the /mcp settings menu no longer open in background sessions
MCP servers configured with an empty URL now show as “not configured” in /mcp instead of a config error
/usage now shows your last-known usage bars with an “as of” note when the usage endpoint is rate-limited, instead of an error screen
Fixed Bedrock auth failing with “Session token not found or invalid” for AWS SSO profiles whose sso_region differs from the Bedrock region (2.1.207 regression)

2.1.207

Fri, 10 Jul 2026 16:00:00 GMT

Changed auto mode to no longer read autoMode from .claude/settings.local.json (repo-resident); use ~/.claude/settings.json instead
Fixed an indefinite hang on Windows when AWS credential resolution stalls (e.g. a stuck credential_process): the 60-second stall guard now fires instead of waiting forever.
Plugin hooks/monitors/MCP headersHelper: ${user_config.*} in shell-form commands is now rejected (shell-injection fix). Hooks: use exec form (args array) or $CLAUDE_PLUGIN_OPTION_<KEY>; monitors and headersHelper: read the value inside the script (config file or the server’s env block).
Plugin option values (pluginConfigs) are no longer read from project-level .claude/settings.json; only user, --settings, and managed settings are honored
Fixed /usage-credits amount inputs silently stripping malformed values (e.g. a pasted timestamp) to digits; malformed amounts are now rejected with an error, and amounts over $1,000 require a typed confirmation

2.1.206

Wed, 08 Jul 2026 16:00:00 GMT

Added directory path suggestions to /cd, matching /add-dir behavior
Added a /doctor check that proposes trimming checked-in CLAUDE.md files by cutting content Claude could derive from the codebase

Improved agent view: sessions that edit, merge, comment on, or push to an existing PR now link it in claude agents
Improved agent view: rows now show a colored state word and a classifier-written headline instead of raw tool call text, and the peek opens with full status including the exact ask for blocked sessions
/doctor is now a full setup checkup that can diagnose and fix issues; /checkup is its alias
Reserved the “Claude Browser” MCP server name (alongside “Claude Preview”) ahead of the Claude Desktop pane rename; user-configured MCP servers can no longer register under either name

2.1.204

Tue, 07 Jul 2026 16:00:00 GMT

Fixed TaskStop and TaskOutput failing to find background agents spawned by another agent — errors now list running agents by id and description
Fixed the claude agents composer discarding your typed message when a slash command isn’t available there
Fixed the agent list crashing when opening a stopped session whose conversation was already open in another session
Fixed background sessions showing “Needs input” in the agent list after the question was already answered
Fixed background agent startup failures showing only “exit_with_message” instead of the actual error
Fixed background sessions ignoring effortLevel changes in settings.json when forked through the daemon
Fixed attached background sessions ignoring CLAUDE_CODE_DISABLE_MOUSE and CLAUDE_CODE_DISABLE_MOUSE_CLICKS opt-outs
Fixed /exit incorrectly warning about running background agents after all named agents had completed
Fixed background sessions started from a non-git directory unable to edit files when a WorktreeCreate hook was configured
Fixed the @ directory picker in claude agents not showing registered git worktrees
Fixed background task output on Windows being permanently replaced by an empty file after /clear
Fixed content jumping when scrolling up through long transcript history
Fixed the terminal flickering and jumping while typing in bash mode when a shell-history suggestion was shown
Fixed literal ^[[I / ^[[O escape codes being printed when reattaching to a background session
Fixed LSP-only plugins being incorrectly flagged for disuse when their language servers deliver diagnostics or answer navigation requests
Improved responsiveness while long responses stream: live-preview updates no longer re-render the whole screen
Improved subagent behavior: agents are now less likely to re-delegate their entire task to another subagent
Reduced binary size by ~7 MB and startup memory by ~7 MB by loading a large bundled dependency lazily instead of inlining it
Changed left arrow to no longer close the background tasks, diff, and workflow detail views — press Esc instead
Changed the empty claude agents view to always show the organized sections (Needs input / Working / Completed) with descriptions
Removed the startup “claude command missing or broken” warnings — they now appear in /doctor and /status instead
Removed a redundant navigation hint from the claude agents footer
[VSCode] Added a Settings toggle for “Enable Remote Control for all sessions”

Added a “Dynamic workflow size” setting in /config for controlling how large Claude generally makes dynamic workflows (small/medium/large agent counts) — an advisory guideline, not an enforced cap
Added workflow.run_id and workflow.name OpenTelemetry attributes to telemetry emitted by workflow-spawned agents, so a workflow run’s activity can be reconstructed from OTel data
Fixed a crash in the inline Ctrl+R history search when accepting or cancelling while the search was still scanning the history file
Fixed /rename on background sessions being reverted when the job restarts, which broke addressing the session by its new name
Fixed transient mTLS handshake failures when settings were re-applied during an in-place client certificate rotation
Fixed commands sent from Remote Control (mobile/web) into an interactive session failing with “Unknown command”
Fixed images and files sent from the Remote Control mobile or web app without a caption being silently dropped
Fixed the sign-in URL printed by claude auth login and claude mcp login --no-browser not being reliably clickable when it wraps over SSH — it is now emitted as a single hyperlink
Fixed opening a chat from claude agents sometimes failing with “currently running as a background agent” followed by a worker crash/respawn loop
Fixed workflow scripts with unicode quote escapes in strings being corrupted before parsing; workflow parse errors now show the offending line instead of always blaming TypeScript
Fixed voice dictation retrying in an unbounded loop when the microphone or audio recorder fails — repeated capture failures now pause voice input
Fixed /remote-control sessions showing the wrong permission mode in the mobile and web apps
Fixed resuming a session by name, or opening the resume picker, taking minutes and using a large amount of memory in repositories with many git worktrees
Fixed installer and updater downloads failing immediately with “aborted” when a proxy or network drops the connection mid-download — transient connection drops now retry
Fixed re-invoking an already-loaded skill appending a duplicate copy of its instructions to context
Improved /workflows agent list layout: wider titles, a dedicated time column, shorter model names, and no per-row tool-call counts
Improved MCP error messages: clearer error when a server config has url but no type, suggesting "type": "http" instead of the misleading “command: expected string”
Changed /review <pr> back to a fast single-pass review; use /code-review <level> <pr#> for the multi-agent review at a chosen effort level

2.1.201
