Changelog - Claude.ai Documentation

2026-08-06

General

Added a “Start a new project” option to the “Add to project” menu, which opens the create-project dialog.
Added Esc as a way to end voice mode in the chat composer.
Added the ability to add suggested skills in local sessions, and plugins from your personal marketplaces, directly from their suggestion cards.
Fixed Claude Desktop on Linux entering a crash-and-relaunch loop that consumed heavy processor time when automatic session restore ran into persistent graphics failures.
Fixed starting a chat inside a project showing a blank screen until the response finished, and leaving the chat without its project name or title.
Fixed the scheduled-task prompt editor not being announced to screen readers as a labeled multiline text box.

Code

Added session-window restore: Claude Code session windows that were open when you quit now reopen the next time you launch the app.
Changed permission-mode picks so they apply to the folder where you made them instead of becoming a machine-wide default.
Removed the “Always allow” option when approving dev server starts in the Browser preview; each new server start now asks, and a server that has crashed asks again instead of restarting silently.
Fixed “Try again” on session-error cards sometimes doing nothing, and a failed send’s retry card and prompt text now survive an app relaunch.
Fixed leftover session workspaces building up on disk until new sessions could fail with a disk-space error.
Fixed repository pickers in project settings and scheduled tasks timing out or omitting repositories in large organizations; they now load quickly, can search every repository, and can load more results.

Cowork

Added a ⋮ menu to scheduled tasks in the sidebar, including Mark as unread for the latest run.
Added a confirmation before a link in a live artifact opens in your browser, with a per-site “Don’t ask again” option.

Added updateViaUpdatesHost. Set it to true to read the update feed from releases.claude.com, a host that serves only the desktop update check and carries no model API, so networks that block api.anthropic.com can still receive updates. Installer downloads continue to come from downloads.claude.ai. Defaults to false.
Added an access mode to each allowedWorkspaceFolders entry. Set mode to ro to let Claude read and search a folder without changing it: in Cowork, writes are blocked and Claude is directed to put modified copies in the session outputs folder. In the Code tab this covers Claude’s file tools only; Bash in the Code tab and SSH sessions do not yet enforce it. Entries without mode stay read-write, so existing configurations are unchanged.
Added optional :port suffixes to coworkEgressAllowedHosts entries, for example internal.corp.com:8443 or *.corp.com:8443, restricting that entry to the named port. This applies to the sandbox’s web fetch now, and to shell egress once the updated virtual machine image ships; on the Code tab, a port-scoped entry is treated as its bare host (any port). Entries without a port keep allowing any port, and an invalid entry is dropped on its own with a warning in the logs.
Added settings that decide where users sign in for inference to the one-time bootstrap consent prompt: the Azure AI Foundry Entra tenant and client, Bedrock IAM Identity Center, the Vertex OAuth client and workforce identity, and gateway OIDC. Set trustBootstrapDelivery to true in your device-management profile to accept these for everyone in advance.
Added the merged Chat and Cowork home as the default. The “New” button starts a chat or a task from one composer, and the sidebar shows Home, which lists chats and tasks together, alongside Code.
Changed the trustBootstrapLocalExec key name to trustBootstrapDelivery, reflecting that it now covers sign-in targets as well as helper scripts and connectors. The previous name continues to work in existing profiles.
Fixed chats started inside a Project not picking up the Project’s Instructions and Context links, including reading the files linked there.
Fixed Code sessions on a custom gateway endpoint ending with an idle-timeout error while the gateway was still sending keep-alive responses.
Fixed Code tab sessions on gateway and direct API key deployments still sending nonessential traffic to api.anthropic.com after an administrator turned off nonessential telemetry.
Fixed model selections provided by your deployment being overridden by an out-of-date Claude Code managed-settings.json left on the device.
Fixed the published bootstrap-config-v2.schema.json describing flat keys instead of the nested shape the app’s own configuration export uses.

2026-08-04

General

Added a chevron next to the composer’s microphone button that switches between dictation and voice mode and keeps your choice; clicking the microphone now starts dictation right away.
Fixed ⌘K (or Ctrl+K on Windows and Linux) search missing results from tool output and archived sessions.
Fixed a crash on macOS during passkey and Touch ID prompts when the system language is German, Spanish, French, Hindi, Indonesian, Italian, Japanese, or Korean.
Fixed automatic and menu-triggered update restarts interrupting an in-progress Claude Code or Cowork task.
Fixed the app being left with no usable window: a failure during startup now shows an error dialog and records the details to a file, and a window the system shut down under low memory reloads instead of staying blank.

Code

Added automatic resume for sessions interrupted when your computer goes to sleep. A banner with a manual Continue button appears only when resuming isn’t safe, and you can continue the session in the cloud instead.
Added capture and annotation for the page the Browser pane is showing, including external sites, so you can mark up what you see and attach the image to chat.
Fixed a crash while using the in-app browser on pages with heavy console or network activity.
Fixed messages sent while Claude was working disappearing from a session after it was reloaded from disk.
Fixed sessions sometimes becoming permanently unopenable, showing “No messages yet” while their conversation history was still on disk.
Fixed starting a session and swapping repositories stalling in organizations with very large repository lists: the pickers now load repositories page by page, find the rest as you type, say when more are available by searching, and report a failed search instead of showing empty results.

Cowork

Added pasted and attached images to the session’s uploads folder, so Claude can open and edit the actual file.
Fixed “Allow for this task” not appearing for connector tools when your organization has turned off persistent “Always allow”.
Fixed documents showing an internal file id instead of their title, including in export filenames and approval prompts.
Fixed long-running workspace shell commands, such as large database queries, being cut off too early.
Fixed scheduled task problems: a cron expression using 7 for Sunday never ran, stalled runs kept running in the background until the app was restarted, and “Allow for all scheduled runs” appeared on prompts where the choice could not be saved, so the task asked again on every run.

Added Projects for organizing Chat conversations: create a project, start a chat inside it, or move existing chats in. Projects stays available even when your administrator has turned the Cowork tab off.
Added inferenceGatewayOidcAuthFlow and inferenceVertexWorkforceAuthFlow, which choose whether identity-provider sign-in for gateway and Vertex workforce-identity credentials runs in the system browser (the default) or through the operating system’s Microsoft account broker on Windows and macOS, so sign-in can satisfy Conditional Access policies that require a managed device.
Added managedMcpServers[].oauth.authFlow, which lets a managed connector sign in through the operating system’s Microsoft Entra account broker on Windows and macOS, so Conditional Access policies that require a managed device no longer block it. Devices without a broker keep using browser sign-in.
Added skillCreationEnabled, which controls whether users can create and upload their own skills. It defaults to on; setting it to false hides the creation and upload surfaces and turns off Claude’s skill-creation tools. It appears in the Setup window under workspace restrictions.
Added trustBootstrapLocalExec. Each user is now asked once for consent when the bootstrap configuration includes settings that run local commands, such as credential helpers and local connectors. Set this key to true to accept them for everyone in advance. It defaults to false and is accepted only from MDM or a local configuration file.
Added a built-in GitHub connector to managedMcpServers: set server to github and supply your own GitHub OAuth app client ID with the device flow enabled. The new host, toolsets, and readOnly subfields point the connector at a GitHub Enterprise Server instance, choose which toolsets load, and offer read tools only. The connector is also configurable from the Setup window.
Added support for mounting Windows mapped network drives into the Cowork sandbox, so shell commands and document processing can work with files on network drives, and fixed adding a mapped network-drive folder mid-session being rejected with a message to use the folder picker.
(breaking) Changed the nested v2 bootstrap response: deploymentDisplayName and deploymentDisplaySubtitle now sit under appearance, and endUserAttribution and userContentRendererUrl under workspace. The flat MDM key names are unchanged.
Changed managedMcpServers and microsoftAuthBroker to be supported on standard deployments as well, so an administrator can enable the built-in Microsoft 365 connector by adding it to managedMcpServers through MDM. It stays off unless configured.
Changed where several keys can be delivered from: claudeAiImport, deploymentDisplayName, and deploymentDisplaySubtitle now accept values from MDM and a local configuration file as well as a bootstrap server, and disableDeepLinkRegistration, microsoftAuthBroker, userContentRendererUrl, inferenceFoundryTenantId, inferenceFoundryClientId, inferenceCredentialHelper (with its TTL, timeout, and silent-refresh keys), inferenceBedrockProfile, inferenceBedrockAwsDir, inferenceBedrockAwsCliPath, and inferenceVertexCredentialsFile can now be delivered by a bootstrap server. The keys that name a local executable go through the consent prompt above.
Deprecated organizationPluginsUrl and removed it from the configuration reference. The key is still honored, but organization plugins are better configured with allowedPluginMarketplaces.
Updated enduserAttribution to the corrected spelling endUserAttribution. The previous spelling is still accepted and now records a configuration warning.
Fixed connector sign-in recovery: connectors no longer ask you to sign in again after a slow startup when the credentials are still valid, and the GitHub connector shows its Reconnect card on the next tool call after its token is revoked on github.com instead of staying stuck.
Fixed tasks failing with “Couldn’t start this task” for the rest of the session when the app launched while the network or the sign-in credential was unavailable.
Fixed the app losing administrator-enabled features, such as the Chat tab, for the rest of the session when the organization’s configuration server was unreachable at launch. It now retries in the background and recovers.
Fixed the home composer and sidebar still offering Cowork when an administrator has turned the Cowork tab off; Cowork is now hidden instead of greyed out, while Chat and Projects remain available.

2026-07-24

General

No user-facing changes.

Code

No user-facing changes.

Cowork

Fixed plugin hooks silently doing nothing on Windows.

Added the mcpPersistentAlwaysAllowEnabled managed configuration key, letting admins disable the persistent “Always allow” approvals for MCP tools while keeping session-scoped approvals available.
Added the five-level effort selector for Claude Opus 5 in the model picker. Extended thinking is always on for Opus 5.

2026-07-21

General

Added an option to keep custom plugin marketplaces up to date automatically, and fixed a marketplace refresh reporting success before the sync ran and re-adding an existing marketplace not refreshing its contents.
Improved keyboard and screen reader support across the app: settings tabs and share-visibility choices respond to arrow keys, dialogs announce meaningful titles, decorative graphics no longer clutter screen reader output, and the find bar, search fields, and pane resize handles show a visible focus outline and announce their size.
Fixed failed uploads being reported as corrupted or unsupported files, and retries showing a “Server is busy” message for unrelated errors.
Fixed safety-block notices suggesting you switch models when no alternative model was available for that topic.
Fixed the app failing to launch when its settings file or logs folder was corrupted, and saved sessions disappearing after a relaunch when one session’s stored data was invalid.
Fixed the app window resizing abruptly and losing its saved size and position when signing in or out; it now animates smoothly in place.

Code

Added iOS Simulator support: Claude Code can build your iOS app, launch the simulator, and verify the result without leaving the session.
Added iOS Simulator and Android Emulator buttons to the session titlebar when the agent launches an app on a device, so the pane is one click to reopen.
Added Pause Project, which pauses a project’s coordinator and new session spawning from settings and shows a Resume banner above the composer.
Added screenshot annotation in the composer: click a staged image, open the pencil, and draw with pen, shapes, text, and colors before sending.
Improved how large sessions open: the newest messages paint first while older history loads in the background.
Fixed Code sessions affecting the wrong files: background worktree cleanup could switch or reset the main repository checkout when a worktree folder was only partially removed, and new sessions could copy uncommitted files from the original folder.
Fixed session list problems: finished sessions still showing as running, deleted sessions reappearing as empty “Session not found on disk” entries after an update, archived sessions still appearing active on claude.ai and other devices, and sessions started from claude.ai missing Rename, Archive, and Delete in the sidebar menu.
Fixed the app freezing when Claude Code updated its configuration file during concurrent use, and web pages in the Browser pane freezing the app with alert and confirm dialogs.

Cowork

Added /usage and /cost to Cowork tasks: an inline card shows your plan limits and the session’s usage without sending anything to the model.
Improved background computer use so it types faster and no longer leaves menus stuck open on screen.
Updated folder access prompts for cloud Cowork tasks to note that files Claude uses leave your device and are processed on Anthropic’s servers.
Fixed changes to Instructions for Claude sometimes not applying to new sessions, and edits reverting to an earlier version while a session was running, including after an app restart.
Fixed Cowork workspace problems: the Windows workspace failing to start when its virtual disk files were compressed, a backgrounded shell command leaving a session stuck reporting “already running”, and bash commands failing when several subtasks ran them at once.
Fixed the message input staying stuck in a sending state when a folder access dialog went unanswered.

Added deploymentDisplayName and deploymentDisplaySubtitle to customize the deployment name and an optional subtitle shown in the account menu and sidebar.
Added enduserAttribution, which shows the signed-in user’s identity in the sidebar, account menu, and Code tab, and includes it as the OpenTelemetry enduser.id attribute on telemetry sent to your configured collector. Administrators can turn it off, and an existing static enduser.id is kept.
Added oauth.authorizationUrl and oauth.tokenUrl to managed MCP servers for identity providers that do not serve a discovery document, and oauth.additionalRedirectReferrerHosts to allow sign-in callbacks from hosts other than the authorization URL’s.
Added userContentRendererUrl, which sets the HTTPS origin that renders artifact and file previews; leave it unset to use the default Anthropic-hosted renderer.
Added a broker option to inferenceFoundryAuthFlow that signs in to Azure AI Foundry through the operating system’s native account broker on Windows or Company Portal on macOS, so sign-in can satisfy Conditional Access policies that require a compliant device. Windows and macOS only.
Added a Usage page in Settings for custom deployments, showing token usage across Chat, Cowork, and Code.
Added Microsoft 365 Teams tools (send to a chat, channel, or thread; create a chat; @mention people) and formatted-body support for Outlook reply drafts.
Added the 1M context option in the model picker for gateway-discovered models that report the capability in /v1/models, without requiring an inferenceModels entry.
Changed telemetry on bootstrap-server deployments to default to disabled until the server explicitly enables it (previously only FedRAMP hosts), and added the ability to disable error and usage reporting through bootstrap configuration.
Fixed managed MCP connectors: a server that requires authentication now opens a sign-in window even when its configuration does not explicitly enable OAuth, and an oauth entry with sign-in fields but a missing or empty clientId is now rejected at load with a clear error instead of silently attempting automatic registration.
Fixed managed MCP tool policies that block all tools by default with per-tool exceptions denying the excepted tools in Claude Code sessions.
Fixed sessions, skills, and plugins intermittently disappearing after sign-in or configuration changes.
Fixed the Claude.ai sign-in option being hidden on deployments configured with a bootstrap URL; it is now hidden only when the administrator explicitly disables the deployment mode chooser.
Fixed the bundled Microsoft 365 connector showing only an opaque tool error when its sign-in expired; it now shows an inline Reconnect card.
Fixed the token-cap setup fields so the maximum tokens per window and the token cap window hours are required together; setting only one previously produced a cap that enforced nothing.

2026-07-19

General

Fixed sessions on Windows failing on every turn with a “Socket is closed” error when traffic passed through a corporate proxy that inspects encrypted connections, by updating the bundled Claude Code CLI to 2.1.215. Interrupted responses now retry on a fresh connection instead of ending the turn.

Code

No user-facing changes.

Cowork

No user-facing changes.

No user-facing changes.

2026-07-16

General

Improved responsiveness while artifacts generate, so typing and scrolling stay smooth during generation.
Improved the “Add to project” menu to show only projects you can move into, with your own projects listed first.
Fixed rare freezes when a transcript contained very large whitespace-padded messages or tool output.
Fixed tool errors blaming an organization policy when a site was actually blocked by your own site permissions or settings.

Code

Added controls for project owners to remove members from a shared project and copy an invite link from the members dialog.
Added per-row actions to queued messages (Edit in composer, Send now, and Remove), with right-click support.
Fixed a new session sometimes taking over the directory another session was still working in.
Fixed Code sessions hanging at startup when skill syncing was slow, and tools on your shell PATH staying undetected when shell environment detection timed out at startup.
Fixed freezes, a stuck “loading earlier messages” spinner, and blank rendering when scrolling back through very large session transcripts or when a running task’s output grew very large.
Fixed the New session button, ⌘N (or Ctrl+N on Windows and Linux), and the project header ”+” discarding an unsent composer draft.

Cowork

Improved writing drafts to consistently appear as preview cards before being staged in a connected app such as Slack.
Fixed documents Claude creates not reliably opening in the editor.
Fixed files edited by Claude sometimes reading back stale or truncated content on Windows.
Fixed the chat window freezing and not updating while Claude uses your computer.
Fixed the document editor sometimes attributing your own typing to Claude while autosaving.
Fixed working documents disappearing from the Documents panel after a temporary disk error.

Added disableBrowserExternalNavigation, which admins can set to true in Claude Code’s managed-settings.json to keep the Code tab’s Browser pane limited to localhost for both users and Claude. Local dev servers and file previews are unaffected.
Added otlpTracesEnabled (beta), which also exports OpenTelemetry traces from Cowork tasks and Code sessions to your configured collector.
Updated the allowed workspace folders policy to also apply to Code sessions on SSH hosts, evaluated against the folders on the remote host.
Fixed enforcement of the managed Auto mode opt-out.
Fixed plugins being treated as required by your organization when their marketplace name merely resolved under a required marketplace entry; only the exact entry a name resolves to now applies, so affected plugins can be uninstalled again.
Fixed saving a skill created in chat failing; skills now save to the app’s local skill storage.
Fixed tools without a configured toolPolicy offering only Allow once and Deny; they now show the full set of approval options (Allow for this task, Allow for all tasks) and the prompt-injection warning. Explicit ask policies still prompt on every call.

2026-07-16

General

Fixed installed extensions failing to load and showing an endless loading state.

Code

No user-facing changes.

Cowork

Fixed a status indicator that stayed on after a conversation finished.

No user-facing changes.

2026-07-14

General

Changed the web-fetch permission prompt to default to “Allow all for this website” when that grant is available; “Allow once” stays the default otherwise, and pressing Enter always answers “Allow once”.
Updated the embedded Claude Code engine to the latest version.
Fixed a crash on launch when Claude’s worktree bookkeeping file couldn’t be read or written.
Fixed brief app freezes when opening terminals or switching sessions on Windows, and when the @ mention menu refreshed the list of open windows.
Fixed scheduled tasks and routines: editing a routine no longer deletes its one-time schedule, “Run now” no longer silently does nothing until the app restarts, and you can now rename routines and scheduled tasks from the edit dialog.
Fixed session exports that could produce an archive without the transcript; the transcript is now always included as transcript.jsonl, and the export shows a clear error when it can’t be included.
Fixed the “Sign in again” prompt not appearing when a background session was blocked for session freshness, including while the desktop was idle.

Code

Added a browser-style address bar to the preview pane, and a clear message, with the option to open the site in your browser, when a page can’t be displayed instead of showing a blank page.
Added the ability to pin artifacts from the gallery or the artifact viewer, and to filter the gallery to your pinned artifacts.
Improved SSH session connection handling: messages no longer hang after the computer wakes from sleep, sessions recover from repeated disconnects, and a reconnecting indicator appears while the connection is restored.
Fixed permissions.defaultMode in Claude Code settings being ignored for new sessions after a per-folder permission mode had been chosen.
Fixed branch switches on large repositories failing after an uncommitted-changes stash timed out, and restored your stashed changes when a switch fails.
Fixed several session reliability problems: a session could get stuck showing “running” and queue new messages forever, a just-started session could disappear from the sidebar or show “session could not be found” during startup, and streamed responses could break or show a literal “undefined”.

Cowork

Added a live word count and a copy button to each document bar above the composer.
Changed Markdown files Claude delivers to open in the document editor instead of a plain-text preview, without flashing the old viewer first.
Changed the composer to keep the standard Send button while a response is running: it appears when you type, and sending mid-response queues your message instead of showing a separate Queue button.
Fixed Claude’s mid-task replies not appearing in the conversation; they now show under a collapsed “Working notes” row.
Fixed screenshots from connected browsers and computer use not being saved to the task folder.
Fixed text typed in one conversation appearing in other conversations’ composers when switching between sessions.

Added envHelper and envHelperTtlSec subfields to managedMcpServers, letting a managed stdio server load environment variables from an admin-provided helper executable.
Added an All tab to organization plugins that browses and searches every configured marketplace at once, and labeled plugins with their source marketplace so they can be filtered when more than one is configured.
Added support for the eu and us multi-region Vertex AI endpoints, required for the newest models with EU and US data residency.
Added the disableFeatureDiscovery key, which hides unprompted feature announcements such as the post-update “What’s new” nudge and new-feature tips. Release notes remain available from the menu.
Fixed remote MCP connectors whose headersHelper mints short-lived credentials failing one token-lifetime after connecting: the helper now re-runs before expiry and the refreshed headers are applied to the live connection. The new headersHelperRefreshBufferSec subfield of managedMcpServers tunes how far ahead of expiry the refresh runs.
Added the prefer1m subfield to inferenceModels, which makes a model’s 1M-context variant the default picker selection when paired with supports1m.
Added the toolSearchEnabled key. When enabled, Code and Cowork sessions load MCP tool schemas on demand instead of placing every schema in context up front, which helps when many configured tools would otherwise crowd the context window. Requires an inference endpoint that forwards anthropic-beta request headers.
Bootstrap-delivered model configuration is now forwarded to Claude Code sessions in third-party deployments.
Changed the projects environment picker to respect an organization policy that hides Anthropic-managed environments.
Removed the Beta designation from the chatTabEnabled and chatAdvancedFileAnalysisEnabled keys; the Chat tab and advanced file analysis are now generally available. Availability is unchanged, and both remain opt-in.
Fixed a bug affecting third-party plugins installed from external sources (GitHub, URL, or npm).

2026-07-14

General

Fixed an issue where permission prompts and in-session questions could silently stop appearing after an input-handling error — if Claude asked a question or requested permission and the prompt never showed up, this release fixes that. (Updates the bundled Claude Code CLI to 2.1.209.)

2026-07-09

General

Fixed claude:// deep links being ignored when opening one launched the app from a closed state, including on Windows and Linux.
Fixed device attestation failing on Windows when sending several messages at once.
Fixed garbled tool summaries in the transcript: descriptions that don’t start with a recognized verb (for example “Final verification”) now appear as written instead of being mis-conjugated.
Fixed skill proposal and skill-file cards failing to save with “Couldn’t save this skill” when a skill of that name already exists; they now offer “Update skill” and a replace confirmation.
Fixed the app forgetting your last-used tab (for example Code) after an update or re-login.
Fixed the menu bar usage menu showing an empty progress bar for extra usage when the spend cap is unlimited.

Code

Added a Troubleshooting option to import Claude Code CLI sessions found on this computer into the session list.
Fixed a typed <channel-message> turn rendering as a spoofable “Message from {server}” card instead of as your own text.
Fixed cross-session messages going missing in the transcript: messages from another session no longer disappear when they arrive in the same turn as other content or when their envelope can’t be fully parsed.
Fixed file links to files outside the working directory, including reports Claude writes to its scratchpad, showing “This file is outside the working directory” instead of opening.
Fixed the context window indicator and token count staying at the pre-compaction value after compacting a conversation.

Cowork

Fixed admin-configured plugin marketplace sync failing behind corporate proxies on macOS.
Fixed plugin connectors sometimes missing from the Connectors list and tool permission prompts when they were slow to start.
Fixed skills saved in a remote session sometimes still returning “Unknown command” right after saving.
Fixed the “Run this task while your Mac sleeps” setting turning itself off after an app update.

Added * wildcard matching for managed MCP toolPolicy keys; partial wildcard keys such as "outlook_*" in existing configurations now take effect, including any allow wildcards, which pre-approve the tools they match. Exact keys and the standalone "*" key behave as before.
Added support for exporting Cowork task telemetry over otlpProtocol: grpc on macOS and Linux when no network proxy is configured.
Fixed Azure AI Foundry sessions failing with an authentication error on every message after interactive Microsoft Entra ID sign-in.
Fixed gateway-SSO bootstrap dropping cross-origin managedMcpServers entries, so admin-provisioned third-party connectors reach the app under device-code sign-in.
Fixed MCP connectors failing to connect through gateways that optionally request a TLS client certificate, even though the connection test passed.
Fixed sign-in timing out with identity providers (such as PingFederate) that redirect via a rendered page after authentication.
Fixed third-party settings ignoring managed configuration: the Claude Code pane now follows isClaudeCodeForDesktopEnabled, the Developer tab hides when isLocalDevMcpEnabled is off, and the Capabilities and Voice settings no longer appear.

2026-07-07

General

Added automatic updates on Linux through the Anthropic apt repository, so new versions arrive with apt upgrade (and unattended upgrades where enabled).
Added the ability to archive or delete the current chat, project, task, or coding session directly from the command palette (⌘K, or Ctrl+K on Windows and Linux).
Fixed bank payment-verification (3DS) pages not loading during checkout.
Fixed MCP connectors in artifacts being silently dropped; approving a connector now reliably grants its tools to the artifact, and a previously stuck approval heals itself the next time you approve.
Fixed repeated crashes on Linux caused by unstable graphics acceleration; the app now turns acceleration off automatically and tells you.
Fixed the app becoming unresponsive when a session folder is on a slow or disconnected network drive.

Code

Added descriptive branch names for local Code sessions, derived from your first message, in place of the random adjective-noun names.
Changed the default transcript and composer width to a narrower, more readable column; a width you already chose in Settings → Appearance is preserved.
Fixed “Open in Finder”, “Open in editor”, and “Attach to chat” doing nothing, or using the wrong path, for files in the diff panel when the session folder differs from the repo folder.
Fixed freezes and stalls: while restoring a large number of sessions at startup, while builds or file syncs churned files inside a watched folder, and while the diff panel refreshed during a response.
Fixed newly trusted folders sometimes failing to start a session with a “workspace is not trusted” error.
Fixed security-key and phone sign-ins not completing in preview tabs.

Cowork

Added a copyright-access notice in the session timeline when Claude in Chrome first operates on certain news publisher sites.
Added keyboard access to the preview pane: Tab reaches a “Preview page” control, Enter moves focus into the loaded page, and F6 (or Ctrl+F6) moves it back out.
Fixed Cowork offering terminal access, and showing an impossible fix suggestion, on devices whose operating system cannot provide the virtualization its isolated environment needs (such as ChromeOS), where every command immediately failed.

Added inferenceFoundryAuthFlow to choose how interactive Microsoft Entra ID sign-in for Azure AI Foundry runs: device-code (the default, which shows a code to enter at microsoft.com/devicelogin) or browser, which opens the system browser for an authorization-code (PKCE) sign-in.
Added microsoftAuthBroker; set it to disabled to force browser-based Microsoft 365 sign-in instead of the native Company Portal or Windows account broker.
Added a “session expires soon” warning for Bedrock SSO and AWS-profile sign-in so you can re-authenticate before hitting an error.
Added a startupTimeoutSec option for managed local (stdio) MCP servers and raised the default startup timeout from 10 to 120 seconds, fixing connection failures when a server command downloads packages on first run (for example uvx or npx).
Added support for background agents: long-running tasks now stay signed in after your identity provider’s access token expires.
Added the ability for administrators to grant Microsoft 365 write scopes (send mail; edit calendars and files; send Teams chat; mailbox settings) through managed configuration.
(breaking) Changed the default for Desktop Extensions (.dxt and .mcpb): they no longer load unless you set isDesktopExtensionEnabled to true in managed configuration. Previously they loaded by default and only the install UI was blocked.
Updated allowedPluginMarketplaces (beta) so it can be delivered per-user through the bootstrap server; a response that omits the key leaves MDM-provisioned marketplaces in place.
Fixed a one-time loss of sign-ins on some managed Windows machines after app data moved to a new location.
Fixed AWS credentials not reaching the Code tab’s terminal for Amazon Bedrock configurations that use IAM Identity Center.
Fixed bundled Microsoft 365 and other MCP connectors failing to connect on networks with corporate TLS inspection (custom root CA).
Fixed connection tests reporting false failures: the test now runs MCP helper scripts and checks managed configurations exactly as saved, and uses the same Azure AI Foundry endpoint that sessions use.
Fixed managed MCP connectors failing with a credential-storage error when the server allows anonymous access.
Fixed the Microsoft 365 connector failing to sign in on Macs enrolled with Microsoft Company Portal.
Fixed the setup form incorrectly showing “Blocked address” for internal MCP or OAuth servers on IPv6 enterprise networks.

2026-07-02

General

Fixed apt update failing on Linux after uninstalling a Claude that was installed from the apt repository.
Fixed being asked to sign in repeatedly after a session expired while you were using the app; your in-progress message draft now returns when you sign back in within 10 minutes, and signing out still clears it.
Fixed being unable to disable, delete, or uninstall plugins from GitHub-connected marketplaces, or to remove those marketplaces.
Fixed pressing Enter not sending your message when an @mention had no matching results.
Fixed remote SSH sessions getting stuck in a reconnect loop on very large messages, being lost when the computer woke from sleep mid-reconnect, and occasionally sending the same input twice after reconnecting.
Fixed setup on Windows getting stuck retrying a download when the download folder was locked or inaccessible.
Fixed the file-open spinner on Linux staying up after the download completed.

Code

Added a “Choose folder” option to recover a session whose working folder is missing: the conversation forks into the folder you pick and the stuck session is archived.
Added a “Switch organization” option on the “session not found” page so you can reopen a session link under the right organization.
Added drag-to-reorder for queued messages, and Steer now works for messages that include images.
Improved the Code tab’s live preview: it now reports honest connection and loading status (including when a page arrives but never finishes loading, or a server overloads itself with requests), adds browser-style Back, Forward, and Reload/Stop controls, and lets you close other preview tabs.
Fixed background tasks and workflows continuing to show as running after they finished, the session restarted, or the session was stopped.
Fixed Remote Control sessions spinning forever with no error after you sent a message when the hosting computer was no longer connected.
Fixed the sidebar project + button opening an empty prompt (or pointing at github.com) for GitHub Enterprise repositories.

Cowork

Added click-to-zoom and drag-to-pan to the fullscreen image viewer.
Fixed Computer Use teach mode where the Next and Exit buttons sometimes stopped responding until you switched apps and back, and cleared up teach-mode visuals so the screen-edge glow no longer flickers and the status indicator no longer sticks after you exit a guide.
Fixed dictation dropping back to the text box when started from the mic button in existing sessions.
Fixed document tools in cloud sessions acting on your local files instead of the session’s files.

Added a usage breakdown by model family, source attribution, and usage tips to the /usage card.
Removed automatic addition of Anthropic’s default plugin marketplace on third-party deployments, and removed the disableDefaultPlugins managed configuration key (which had no effect there). Provision marketplaces via allowedPluginMarketplaces (beta).

Added Claude Fable 5 to the model picker for organizations with access.

2026-06-30

General

Added Linux support: Claude Desktop is now available for Debian and Ubuntu on x64 and arm64, installable as a .deb package.
Updated the plugin Directory to show admin-configured marketplaces under the Organization tab and refresh them automatically when the source repository updates.
Fixed plugin and skill downloads stalling for several minutes on a dead connection before retrying; stalled downloads now retry sooner.
Fixed prompt and tool-detail content missing from OpenTelemetry exports for standard deployments that have not set an explicit content-capture policy; third-party deployments are unchanged.
Changed zoom in and out to use smaller steps for finer control.

Code

Added an integrated terminal pane and inline image previews in the transcript for SSH sessions.
Added step-by-step progress and a Stop button while a session’s worktree is being set up, so a long checkout on a large repository can be cancelled.
Added a right-click menu in the Terminal pane with Copy, Paste, and Attach selection as context.
Updated the transcript to mask API keys and tokens by default; click the eye icon to reveal them.
Fixed folder access and cross-session requests being rejected after you approved them when permission mode was Auto or Bypass permissions.
Fixed failed mid-turn message sends (for example, while offline) dropping your text instead of returning it to the input.
Fixed new session worktrees branching from the currently checked-out branch instead of the repository’s default branch, and archived sessions leaving their worktree folders on disk.

Cowork

Fixed a crash when resuming sessions with malformed remote connector data on disk.
Fixed the workspace download restarting from zero after a network interruption; it now resumes from where it left off and retries automatically.
Fixed folder and file names containing a dollar sign being misread, which broke file references.
Fixed dictation immediately dropping back to the text input in existing sessions.
Fixed an error caused by Claude trying to read a document creation skill that was not available.
Fixed clicking a built-in workflow (such as deep-research) in the activity panel’s Skills section showing an empty drawer instead of its name and source.

Added the allowedPluginMarketplaces managed configuration key. Configured git repositories appear under the Directory’s Organization tab.
Added an optional omitOfflineAccess subfield to the inferenceVertexWorkforceOidc configuration. Enable it when an identity provider rejects the offline_access scope; the app then prompts for sign-in each time the identity provider token expires instead of refreshing silently.
Added managed configuration support on Linux: administrators can provision settings in a root-owned /etc/claude-desktop/managed-settings.json, validated against the same schema as the macOS and Windows sources.
Fixed claude.ai sign-in never completing on Windows when an enterprise inference provider is configured.
Fixed subagents failing with an invalid model error on third-party inference providers.
Fixed inferenceModels[].supports1m being ignored, restoring the 1M-context option in the model picker for Bedrock, Vertex, Foundry, and gateway providers.
Fixed the Microsoft 365 connector showing an unexpected admin-consent prompt after updating on tenants with restrictive consent policies when the connector’s Access setting was blank. Also updated the bundled connector with tools to read the signed-in user’s profile and draft reply-all emails.
Improved expired sign-in handling for third-party inference providers and connectors: a sign-in prompt now appears whichever credential type expired, connector authentication errors are shown in Settings and inline in chat with a Reconnect action, and background Code sessions stay signed in across a credential refresh.
Fixed several connector reliability issues: connectors silently stopping mid-session after an OAuth refresh failed instead of prompting to reconnect, connectors configured with both OAuth sign-in and custom headers failing to connect, and admin-configured connectors not appearing in a session until they were signed in.

Fixed locally-configured stdio MCP servers being refused in third-party deployments that don’t use MDM.
Fixed third-party MCP connectors disconnecting on every app restart when the OAuth provider returns a non-standard refresh response.
Fixed Microsoft 365 brokered sign-in failing with “No reply address provided” on managed Macs.

2026-06-25

General

Fixed a crash on launch caused by an unusually large saved session.
Fixed the conversation jumping and the Progress panel flashing when opening a completed task.
Improved keyboard navigation: a message’s action buttons are now a single Tab stop, with arrow keys to move between them.

Code

Fixed high background CPU usage when several Code sessions were open in the same large repository.
Fixed people without a Claude Code seat being sent to the marketing site from /code; they now see an in-app organization switcher.
Added support for custom cron expressions when scheduling local routines.
Added “Open in VS Code”, “Open in Cursor”, and similar actions to the file panel, file tree, plan panel, titlebar, and sidebar in SSH sessions.
Fixed attachment cards for files that exist only inside a session doing nothing when clicked; they now open in the File pane, lightbox, Preview pane, or Files browser.
Added a “Load more” button to the All sessions list for people with many sessions.

Cowork

Fixed workspace setup repeatedly failing with the same checksum error after a corrupted download, until the cache was cleared.
Fixed Cowork sessions losing their project after restarting the app.
Added a one-time prompt before Claude runs a dynamic workflow, explaining what workflows do.
Improved the time it takes to start a session.

Added a managed websearch built-in tool so self-hosted deployments can search the web. Admins configure Brave, Tavily, Exa, or a custom endpoint in managed config, and it is available in both the Cowork and Code tabs.
Added an otlpContentCapture managed setting that lets admins opt in to sending specific categories of unredacted content — user prompts, assistant responses, tool inputs, tool outputs, and raw API request/response bodies — to their OTLP collector.
Updated the Microsoft 365 built-in connector’s scope field to accept MailboxSettings.Read.
Fixed managed connectors that lost their connection staying broken with failing tool calls; they now reconnect automatically on the next tool call, including from newly started conversations, and show a message if reconnecting fails.
Fixed Microsoft 365 connector sign-in failing on Windows because of a broker error.
Fixed a sign-in loop when your organization’s gateway denies access; the app now shows “Access denied” and points you to your administrator.
Fixed the selected model reverting after restarting the app and resuming a session.
Added a disableBundledSkills managed config key that turns off Claude Code’s bundled skills and workflows (such as deep-research) on that device.

2026-06-23

General

No user-facing changes.

Code

Added an inline card for multiple-choice questions from Claude, so you can pick an option and step through each question before your choices are sent as a single reply.
Fixed the app crashing shortly after opening the Code tab when local session history files are very large.
Fixed the integrated terminal eventually failing to open new shells after the app had been running for several days on macOS.
Fixed forked sessions not carrying over pull requests from the original conversation, and pull request rows staying marked as closed after being reopened on GitHub.
Fixed the @-mention dropdown, side-chat panel, and plan-comment popover rendering, resizing, and dismissing in the wrong window when a session is opened in its own window.
Fixed an extra tab opening in the system browser when navigating with the Artifacts pane open.

Cowork

Added the ability to delete Cowork sessions from the sidebar, recents, and Spaces views.

Published the v2 bootstrap-response JSON schema (nested format). The v1 flat schema remains supported.
Removed support for installing connector extensions from local .mcpb and .dxt files.
Fixed the Setup panel being locked when only the auto-update policy was deployed via MDM.
Fixed connectors configured by your organization not appearing until restart after first sign-in.
Fixed the model picker dropping to “Default model” mid-session when a gateway’s model-list response was temporarily degraded.

2026-06-18

General

Fixed the app prompting you to sign in again every day when your claude.ai session was more than a day old.
Fixed Claude Design links in chat navigating the app in place instead of opening Claude Design.
Fixed the app showing a blank window when a network proxy redirects the connection to Claude.

Code

Changed routines to count against your regular usage limits instead of a separate daily included-run limit, and removed the included-runs indicator.
Updated the model picker to show restricted models as non-selectable with an explanatory badge, and to reflect your organization’s allowed default model.
Fixed HTML and SVG file previews showing black text on a dark background in dark mode.
Fixed menus and popovers opening behind the preview panel.

Cowork

Fixed Claude in Chrome file uploads failing for files in the session’s shared folders and outputs.
Fixed scheduled tasks leaving earlier processes running after each scheduled run.
Fixed Windows file paths showing garbled characters in the folder access approval card, and reduced unnecessary folder access denials when allowed workspace folders are configured.

(breaking) Changed the chatCodeExecutionEnabled managed configuration key to chatAdvancedFileAnalysisEnabled. It still lets Claude analyze attached files such as spreadsheets and presentations by running code in a sandbox scoped to the session’s attachments, and remains off by default. Update any managed configuration that sets the old key.
Deprecated the betaFeaturesEnabled managed configuration key; use the per-feature keys chatTabEnabled and chatAdvancedFileAnalysisEnabled instead. The Beta label in the Setup window is now informational only, and the Beta label has been removed from the built-in Microsoft 365 connector presets.
Added the inferenceSessionLifetimeSec managed configuration key. Set it to your identity provider’s session lifetime to show users a re-authenticate reminder before their sign-in expires.
Added ~ and environment variable expansion (such as %APPDATA% and %OneDriveCommercial%) to the allowedWorkspaceFolders setting, so folder paths can vary per user.
Added a per-folder pre-select option to allowedWorkspaceFolders so an administrator-configured folder can appear as a ready chip when users start a new task, and removed the “Create workspace folder?” prompt for administrator-configured folders.

2026-06-16

General

Improved find-in-page to search the entire session transcript instead of only the text scrolled into view, and the find bar now reliably takes keyboard focus when opened.
Added a unified Artifacts view that lists your chat, Code, and Cowork artifacts in one searchable place, with a “New artifact” menu and a “Filter by” control to narrow the list by source.
Fixed keyboard shortcut conflicts failing silently. Assigning a shortcut already held by another app now tells you and keeps your previous shortcut working, and Quick Entry registration errors now appear in Settings.
Fixed the first-run notification explaining that Claude keeps running in the notification area never appearing on Windows.

Code

Added running dev servers to the Background tasks panel, with stop and open-preview actions.
Improved the Code file viewer: images, video, and audio now play inline instead of showing as text, and Markdown, CSV, and image files refresh automatically when Claude edits them.
Updated the model picker. The three headline models appear at the top level with older models and context-size variants under “More models”, each model shows a capability description, and currently-unavailable models appear disabled instead of failing when selected.
Updated the in-session artifact panel: switch between a session’s published artifacts from the title dropdown, see when an artifact was last updated, copy a share link, and open, share, or delete the artifact from the overflow menu.
Changed the Code sessions tab from “Projects” to “All sessions”. It now lists your non-project sessions alongside project sessions and adds a multi-select Environment filter.
Fixed pull request status checks. Failures now show a small warning indicator on the branch row instead of repeated error popups, the “status couldn’t be checked” warning appears less often and can always be dismissed, and only GitHub CLI sign-in problems still raise a notification.

Cowork

Fixed corrupt plugin downloads crashing or hanging the app.
Fixed skills sometimes staying on an older version after being edited until toggled off and on.

Added the Chat tab as a beta feature controlled by the chatTabEnabled managed configuration key. The separate chatCodeExecutionEnabled key lets Claude analyze attachments and create files such as spreadsheets and presentations by running code in an isolated sandbox scoped to the session’s attachments, and is off by default.
Added the betaFeaturesEnabled managed configuration key. Setting it to false disables every beta feature in the deployment, including the Chat tab.
Added Bedrock Mantle as an inference provider option. It reuses the existing inferenceBedrockRegion and inferenceBedrockBaseUrl managed configuration keys and authenticates with a bearer token or a credential helper.
Added anthropicFamilyTier and isFamilyDefault to managed inferenceModels entries. Tag each configured model with the Claude tier it stands in for so tier shortcuts like opus and sonnet resolve to your configured model IDs instead of the canonical names your provider may not route.
Added the inferenceBedrockAwsCliPath managed configuration key to set the AWS CLI’s absolute path. This fixes aws sso login failing when the app is launched from Finder on macOS and the CLI is not on the default search path.
Fixed Google Workspace connectors never starting their OAuth sign-in. The MCP client identifier the app sends to connected servers is now claude-desktop-3p, changed from custom3p-desktop, so update any MCP server allowlists or log filters that match the old value.
Fixed the managed Tool policy * entry being ignored. It now applies as the default for any tool not listed by name.
Fixed organization plugins sometimes not opening from the Directory right after launch or update.
Fixed several connection and sign-in issues: Bedrock sessions now prompt to sign in again after AWS IAM Identity Center expires instead of failing with repeated credential errors, remote MCP connectors no longer stay Connected after a non-refreshable access token expires, the connection test now passes against gateways that optionally request a TLS client certificate, signing in after signing out no longer needs a double click, and sign-in recovery no longer uses stale configuration after a server-side update or leaves the model picker empty until restart.

2026-06-11

General

Added Find Next and Find Previous keyboard shortcuts to in-app search.
Fixed preview panes stealing keyboard focus from the chat input when they reloaded or navigated.
Fixed sessions failing to start after your sign-in expired — the app now prompts you to sign in again.

Code

Added the Files panel to remote and SSH sessions — search the session’s files and open them in the viewer — plus a Show in Files button in the file viewer.
Added a running-tasks button to the activity indicator that opens the Tasks panel, and Bash rows in the Background tasks panel now open to show their output, including a live tail while the command runs.
Fixed SSH sessions: forking no longer opens an empty conversation, and connections no longer fail with “Failed to upload file” errors on remotes first set up by early-2026 versions of the app.
Fixed renaming a session while its title was still generating — the generated title no longer overwrites the name you set.
Fixed the Pull Requests view showing “No open pull requests” when GitHub isn’t connected — it now prompts you to connect.
Added model-picker memory — the picker now remembers your last model choice.

Cowork

Fixed scheduled tasks firing many duplicate runs at once when the computer wakes from sleep.
Fixed remote sessions re-prompting for access to folders you had already trusted.
Fixed plugins becoming corrupted when they synced while you switched accounts.

Added the built-in Microsoft 365 connector — admins can configure it from the Setup window’s server presets. Users sign in through their browser, and Claude can search and read Microsoft 365 mail, calendar, OneDrive, and SharePoint. It requests read-only access by default; admins can grant additional read scopes, such as Teams channel messages and meeting transcripts, with the managed server entry’s scope setting.
Deprecated the “sso” value for the inferenceGatewayAuthScheme managed configuration key in favor of inferenceCredentialKind “interactive” — existing configurations keep working and log a deprecation warning.
Added the inferenceVertexOAuthLoginHint managed configuration key to pre-fill the Google account chooser when signing in to Vertex AI, so users in organizations federated to a third-party identity provider land on the right account automatically.

2026-06-09

General

Fixed Clear Cache and Restart signing you out instead of just clearing caches.
Fixed mouse back and forward buttons not navigating on macOS for mice managed by driver software like Logitech Options+, and added trackpad swipe navigation.
Fixed organization plugins sometimes failing to open right after app launch, and the plugin directory now offers Install again after an uninstall.
Fixed connector, Chrome extension, and plugin toggles in the composer’s ”+” menu not responding when you click directly on the switch.
Fixed an issue where signing in could leave the app unable to start sessions until it was restarted.
Fixed shell-exported custom request headers not reaching Claude Code sessions.

Code

Fixed Claude losing its coding instructions, file-link formatting, and worktree context after a session resumed from idle.
Fixed the preview pane sometimes connecting to an unrelated dev server that was already using the configured port, and it now reopens the dev server you last picked for each project.
Improved responsiveness in Code sessions: smoother streaming of long code blocks, quicker side-panel shortcuts, and less delay opening cloud sessions with many screenshots.
Fixed popovers, dialogs, and the rewind picker not appearing — and typed characters jumping to the end of the composer — when a Code session is opened in its own window.
Fixed the slash-command menu opening behind the side chat panel.
Fixed the source-branch picker showing nothing for SSH sessions with worktree enabled.

Cowork

Added a “Free Up Cowork Disk Space” option under Help > Troubleshooting, and Cowork now cleans up caches and old temporary files automatically when its workspace disk runs low.
Improved the read/unread toggle on sidebar sessions: it now works on the currently open session, has a larger click target, and shows a tooltip describing what a click will do.

Added support for the Fable model family, and for Mythos where your organization has access.
Fixed sign-in failing with external identity providers that reject the offline_access scope — admins can now disable the automatic append.

2026-06-05

General

Fixed reinstalling Claude on Windows failing after an uninstall when IT had installed it for all users.
Fixed the app not starting automatically at login on Windows.
Added a banner when an update fails to install, instead of failing silently.
Fixed built-in connectors staying disconnected after a crash — existing sessions now reconnect them automatically, and disconnecting a built-in connector now signs it out and keeps it disconnected across restarts.

Code

Added math rendering for inline and block expressions in Claude Code transcripts.
Added Ultracode to the effort slider, which selects the highest effort level and turns on dynamic workflows for the session.
Added drag-to-reorder and A→Z sorting for projects in the Claude Code sidebar.
Added triple-click to select a whole code block, plus right-click menu actions to copy a code block or inline code, in Claude Code transcripts.
Fixed resuming Code sessions when the working folder had moved or been deleted — sessions saved with a ~ path no longer show as missing or re-prompt for trust, and a deleted remote folder now reports clearly and offers a Fork session button instead of retrying in a loop.

Cowork

Added a low-disk-space warning before Cowork downloads the files it needs to run.
Added in-session effort and thinking controls for local Cowork projects.
Updated the New project folder picker to default to your Claude data folder (~/Claude/Projects) instead of ~/Documents.
Fixed Claude reporting that a skill was updated when the change was never saved to your account.
Fixed the /schedule command in Cowork showing as unavailable.

Fixed managed connectors and SSO sign-in requesting broader OAuth scopes than the administrator configured.
Fixed three Bedrock sign-in and session issues: SSO sign-in failing behind corporate proxies that intercept secure traffic, expired SSO tokens prompting a new sign-in every hour instead of refreshing automatically, and resumed sessions failing on their first message.
