Claude Code 2.1.273

[What's changed] Added a notification when an MCP server disconnects mid-session and automatic reconnection gives up, pointing at `/mcp`

[What's changed] Added forking a session started with `claude --remote-control` or `/remote-control` from the Claude app; the fork runs as a background session on your computer

[What's changed] Improved responsiveness in long sessions: hook progress and sub-agent activity no longer re-process the whole conversation on every update

[What's changed] Improved the Artifact tool's error when a publish includes a file type artifacts don't serve: Claude is told which types are served and what to do instead, and the terminal shows one plain line

[What's changed] Improved artifact publishing: a publish whose connection drops after reaching claude.ai is now re-sent safely instead of failing or creating a duplicate version

[What's changed] Changed auto mode on Bedrock, Vertex and Foundry to use the local classifier by default for now; set `CLAUDE_CODE_AUTO_MODE_SERVER=1` to use the platform's server-side classifier

[What's changed] Changed sign-in with a Claude account to also request access to your claude.ai plugins

[What's changed] [Claude Tag] Changed Claude to start watching related public channels on its own, such as an incident channel a conversation depends on, instead of only when asked

[What's changed] Added `x-claude-code-request-class`, `x-claude-code-agent-type`, `x-claude-code-prev-tool-durations`, `x-claude-code-compaction` and `x-claude-code-context-compacted` request headers for LLM gateways; opt in with `CLAUDE_CODE_GATEWAY_HINT_HEADERS=1`

[What's changed] Improved the Artifact tool's page read to state the capabilities and database rules the artifact service holds for the page, for anyone who can publish to it

[What's changed] Improved artifact database writes: an update can now remove a single field instead of rewriting the whole document

[What's changed] Changed `OTEL_LOG_TOOL_DETAILS=1` to also include real agent, skill, plugin and MCP server names on cost and token metrics

[What's changed] Changed `/bug` and `/feedback` reports to include only model-behavior params (model, system prompt, tools) from the last API request, omitting request metadata and `CLAUDE_CODE_EXTRA_BODY` fields

[What's changed] [Claude Code on the web] Changed the admin "Share cloud sessions" setting to live under Data and privacy instead of the Claude Code page, where Data and privacy admins can also manage it

[What's changed] [Claude Code on the web] Added a "Discard unsaved changes?" confirmation before the New routine page or the Edit routine dialog throws away a routine name, prompt or edit you typed

[What's changed] [Claude Code on the web] Improved the routine detail page: menu and rename in the breadcrumb, the on/off switch and Run now at the top, and run history beside the routine's settings

[What's changed] [Code Review] Improved suggested fixes to say what the fix must keep working when other code depends on the behavior being changed

[What's changed] [Code Review] Improved review comments that point to a second affected location to state that location's issue in a full sentence instead of a cut-off stub

[What's changed] Fixed Bash commands the permission checker cannot fully analyze skipping the prompt under `permissions.blockReadsOutsideWorkingDirectories`, and a subshell hiding a dangerous `rm` in bypass mode

[What's changed] [Claude Tag] Fixed replying in an older Slack thread while Claude is mid-task sometimes restarting it from scratch and losing work it had not pushed yet

[What's changed] Fixed skills synced from claude.ai staying available after your organization turns Skills off; they now move to the recoverable trash

[What's changed] Fixed `allowManagedMcpServersOnly`, `deniedMcpServers` and `disableClaudeAiConnectors` set via MDM or `managed-settings.json` being ignored when server-managed settings are also present

[What's changed] Fixed 401/403 errors on Bedrock, Vertex and Foundry, and Claude apps gateway 403s, telling you to run `/login`; the message now names the credential to refresh or points to your gateway administrator

[What's changed] Fixed `/login`, `/upgrade`, and `/extra-usage` discarding earlier thinking from the conversation, which forced a full prompt-cache rewrite on the next request

[What's changed] Fixed auto mode stopping for approval when the Artifact tool uploads a file you attached to the chat in a cloud or Remote Control session

[What's changed] Fixed the main prompt dropping a `!` typed at the start while already in shell mode, so negated commands like `! grep …` can be typed

[What's changed] Fixed sub-agents and background agents being reported as failed, with their result never delivered, when the final streamed reply omitted token usage or carried no model id

[What's changed] Fixed the context meter and auto-compact counting advisor-tool turns at roughly twice their real context size, which made auto-compact fire at about half the real window

[What's changed] Fixed saved scheduled tasks running in the wrong session after `.claude/scheduled_tasks.json` was copied into another folder, such as a new worktree

[What's changed] Fixed SDK and `--output-format stream-json` output dropping a subagent's remaining messages and final report after it is moved to the background mid-run (e.g. by `CLAUDE_AUTO_BACKGROUND_TASKS`)

[What's changed] Reverted a 2.1.268 change that checked Read and Edit deny rules on Bash lines the permission checker can't analyze (`eval`, `env -C`); commands like `time -p make build` prompt again instead of being denied

[What's changed] Improved the cloud-session GitHub error for an IP allow list, a suspended app installation or SAML single sign-on to show the cause instead of a generic install hint

[What's changed] Improved `/autofix-pr`: when `gh pr view` fails it now shows gh's own error (sign-in, SAML, rate limit) instead of a generic exit-code line

[What's changed] Improved the in-session SSL certificate and proxy connection errors to name the error code and what to fix, such as `NODE_EXTRA_CA_CERTS` for an untrusted corporate CA

[What's changed] Improved the error when a cloud session can't be created because your Claude login expired or was revoked: it now tells you to run `/login`

[What's changed] Improved the error shown when an MCP server's sign-in expires mid-session to say how to re-authenticate (`/mcp`)

[What's changed] [VSCode] Fixed a red "Claude Code process exited with code 4294967295" banner appearing after completed turns on Windows

[What's changed] [Claude Code on the web] Fixed routines losing access to an organization connector, and still calling the old one, after an admin removed and re-added that connector

[What's changed] [Claude Code on the web] Fixed creating a self-hosted environment from organization settings occasionally failing with a server error and leaving a half-created environment behind

[What's changed] [Claude Tag] Fixed Claude going silent minutes after reinstalling the app when an Enterprise Grid was disconnected but one of its workspaces stayed connected

[What's changed] [Claude Tag] Fixed scheduled tasks set up in an organization-shared private Slack channel silently never posting; they now keep running in the thread they were created in

[What's changed] [Claude Tag] Fixed Claude occasionally dropping a message with an incorrect "couldn't find a Claude Code environment" notice right after your account token refreshed

[What's changed] [Claude Tag] Fixed AWS connections refusing region-less endpoints such as Budgets, Savings Plans, WAF Classic and Import/Export; Global Accelerator requests now sign correctly

[What's changed] [Claude Tag] Improved AWS connection failures: when a request can't be signed, such as a hostname with no region, Claude is told why and how to fix it instead of a bare error

[What's changed] [Claude Tag] Fixed adding a channel manager being refused on Enterprise Grid shared channels, on channels where Claude hasn't been used yet, and on legacy private channels

[What's changed] [Code Review] Fixed empty or content-identical pushes being re-reviewed on GitHub repositories whose owner or name contains a capital letter; these pushes are now skipped

[What's changed] Fixed a long-running session recreating a stub `.git/info/exclude` after the repository's `.git` directory was removed or moved away

[What's changed] Fixed Read on macOS refusing a dragged-in screenshot, or any file the system reports under a second path, with "symlink resolution changed after permission was checked"

[What's changed] Fixed `permissions.blockReadsOutsideWorkingDirectories`: a memory directory chosen by a repository's settings is no longer loaded into the prompt, recalled, indexed, or used by memory extraction

[What's changed] Fixed `/tui` refusing to restart because of an agent-team teammate that had already finished its work and was no longer shown in the agents panel

[What's changed] Fixed `/install-github-app` reporting a SAML single sign-on block as "admin permissions required"

[What's changed] Fixed Remote Control clients attached to a Claude Desktop, VS Code or JetBrains session being refused when they ask for the session's context window usage

[What's changed] Fixed the spinner showing a doubled ellipsis ("……") on compaction status lines such as "Running PreCompact hooks…"

[What's changed] Fixed a false-positive spinner tip suggesting the frontend-design plugin after reading or publishing Artifacts

[What's changed] Improved `/autofix-pr` to say why GitHub webhook delivery couldn't be set up for the PR (for example, no linked GitHub account) instead of a generic warning

[What's changed] Improved `/web-setup` errors: a refused GitHub token now lists the likely reasons and the fix, and a connection failure names a configured proxy or TLS certificate problem

[What's changed] [VSCode] Fixed "Report a problem" still appearing, and `/bug` / `/feedback` opening a report form, for organizations that have product feedback disabled

[What's changed] Windows: Improved the network-path permission check for UNC paths when a mapped network drive was added with `--add-dir`

[What's changed] [Claude Code on the web] Removed the full-page desktop-app download screen that new users without a cloud environment saw on Mac and Windows; they now go straight to setup

[What's changed] [Claude Tag] Fixed OAuth client-credentials and JWT-bearer connections failing with providers that return a lowercase token type; requests now send the standard Bearer scheme

[What's changed] [Claude Tag] Fixed the admin Memory page not listing Slack channels Claude set up on its own even when they had saved memory; admins can now open, edit and delete that memory

[What's changed] [Code Review] Fixed merging the base branch into a PR whose earlier review listed "Additional findings" triggering a full re-review; these pushes now get the lighter follow-up review

[What's changed] [Code Review] Fixed a whole REVIEW.md being ignored because of an @-mention, a code span wrapped across lines, or a backticked HTML tag; only lines linking to changed files are withheld

[What's changed] [Code Review] Fixed `/ultrareview --post` so a retry after a GitHub error posts the findings comment exactly once instead of never or twice; the comment now names the reviewed commit
