Changelog - Claude.ai Documentation

v1.18286.0

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).

v1.17377.1

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.

v1.15962.0

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.

v1.15200.0

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.

v1.14271.0

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.

v1.13576.0

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.

v1.12603.1

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.

v1.11847.5

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.

v1.11187.4

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.
