Changelog

2.1.198

• Claude in Chrome is now generally available
• Added background agent notifications in claude agents — sessions that need input or finish now fire the Notification hook (agent_needs_input / agent_completed)
• Added /dataviz skill for chart and dashboard design guidance with a runnable color-palette validator
• Gateway: added Claude Platform on AWS (anthropicAws) as an upstream provider; model-not-found responses now advance the failover chain
• Background agents launched from claude agents now commit, push, and open a draft PR when they finish code work in a worktree, instead of stopping to ask
• The built-in Explore agent now inherits the main session's model (capped at opus) instead of running on haiku
• Subagents and context compaction now inherit the session's extended thinking configuration, improving output quality on delegated tasks
• Fixed brief network drops mid-response aborting the turn — transient errors like ECONNRESET now retry with backoff instead of failing
• Fixed excessive background classifier requests when sandboxed processes repeatedly accessed the same network host
• Fixed background tasks in web, desktop, and VS Code task panels getting stuck on "Running" after they finish or after resuming a session
• Fixed agent teams: a teammate that dies on an API error now reports "failed" to the lead, and messaging a stuck teammate wakes it to retry immediately
• Fixed the /diff panel not refreshing when you switch branches or commit outside the session
• Fixed markdown tables overflowing and wrapping their right border when rendered in fullscreen mode
• Fixed Claude Platform on AWS and Mantle sessions dead-ending with "Please run /login" when the STS token expires — awsAuthRefresh now runs automatically
• Fixed "no route to host" for local-network hosts in macOS background agent sessions by declaring Local Network entitlements
• Fixed /desktop failing with "Cannot determine working directory" after entering and exiting a worktree
• Fixed background agents repeatedly showing "Reconnecting…" every ~52 seconds on macOS while the agents view was open
• Fixed pressing ← inside claude attach <id> exiting to the shell instead of opening the agent view
• Fixed claude --bg silently creating an unattachable session when combined with --print/-p; the conflicting flags are now rejected up front
• Fixed the workflow progress view dropping the earliest agents from the list while the phase counter stayed correct in SDK and desktop-app sessions
• Fixed .claude/rules/ conditional rules not loading when the target file is reached via a symlinked path
• Fixed Cmd+click not opening URLs in fullscreen mode in Warp on macOS
• Fixed double-click word selection in fullscreen mode to select the entire URL including the scheme
• Fixed plan mode not auto-allowing read-only tool calls when a session starts in plan mode
• Fixed /branch deriving its default fork name from the compaction summary instead of the first real prompt
• Improved focus mode: subagents launched in a turn now appear in its activity summary, and completed background notifications fold into a single count
• Improved syntax highlighting accuracy in code blocks, diffs, and file previews by upgrading to highlight.js 11
• Keyboard shortcut hints now show opt/cmd instead of alt/super when connected from a Mac over SSH
• Improved API retry UX: the error reason is now shown after the second attempt, and a status page link replaces the spinner tip when the API is overloaded
• /login now opens the sign-in dialog from the claude agents view instead of saying it isn't available
• Subagents now treat messages from the agent that launched them as normal task direction; an agent's message is still never treated as the user's approval
• Removed the /agents wizard; ask Claude to create or manage subagents, or edit .claude/agents/ directly

2.1.197

• Introducing Claude Sonnet 5: now the default model in Claude Code, with a native 1M-token context window and promotional pricing of $2/$10 per Mtok through August 31. Update to version 2.1.197 for access. https://www.anthropic.com/news/claude-sonnet-5

2.1.196

• Added support for organization default models — admins set it in the org console; it shows as "Org default" (or "Role default") in /model when you haven't picked one yourself
• Added readable default names for sessions at start, making them easier to identify and message
• Added clickable file attachments in chat — Cmd/Ctrl-click reveals the file in Finder/Explorer
• Security: claude mcp list/get no longer spawn .mcp.json servers that a repo self-approved via a committed .claude/settings.json; untrusted workspaces show ⏸ Pending approval
• Fixed waking a background job permanently deleting its conversation and re-running the original prompt when the transcript probe misread a real transcript; the file is now set aside, never deleted
• Fixed the rate-limit warning flickering off and rate-limit telemetry being over-counted when multiple parallel requests were in flight at the moment a usage limit was hit
• Fixed duplicate recap lines after a background session's turn: a schema-rejected StructuredOutput attempt no longer renders alongside its retry
• Fixed PowerShell git diff/git grep, egrep/fgrep, and quoted search patterns containing | being reported as failures when they exit 1, matching Bash behavior
• Fixed multiple claude agents side panel issues: keyboard focus getting stuck when opening an agent, background jobs losing their subagent types on every open, and sessions showing incorrect status while actively running
• Fixed claude agents --dangerously-skip-permissions silently falling back to auto mode instead of showing the bypass disclaimer and applying bypass mode to spawned agents
• Fixed mid-turn crash recovery for Remote sessions — sessions interrupted by a server restart now auto-resume on the next worker
• Fixed sessions moved with /cd reappearing in the old directory's resume list after a non-graceful exit when the old path contained special characters
• Fixed claude plugin validate skipping local plugins whose source is "." and stopping after the first error class
• Fixed Esc Esc at an idle prompt not opening the rewind menu (regression); use Ctrl+C or Ctrl+X Ctrl+K to stop background agents
• Fixed MCP OAuth requesting the authorization server's full scopes_supported catalog when no scope is specified, causing invalid_scope failures on GitLab self-hosted and other enterprise IdPs
• Fixed /context showing 0 tokens for all tool groups on Bedrock
• Fixed /deep-research misreporting verifier failures as "all claims refuted" instead of unverified
• Fixed plugin dependency version pins not being honored when the marketplace was added as a local folder path backed by a git repo
• Fixed claude agents session status: completed rows no longer flip between "Done" and "Needs your input", stalled agents are now labeled "Needs attention", and results that mention a PR show a clickable link
• Fixed voice dictation swallowing spaces and spuriously starting a recording during very fast typing when voice mode is enabled
• Improved background session reliability: long-running commands and workflows now survive the session's process being stopped, restarted, or updated — including on Windows, where background shells are handed off instead of being killed
• Improved background agents: workers killed by a daemon restart are now automatically resumed from where they left off the next time the agents view opens
• Improved /code-review workflow: merged five cleanup finders into one, cutting token usage by roughly 25%
• Reduced per-frame rendering work in the terminal UI by skipping no-op subtree walks during streaming
• The streaming idle watchdog is now on by default for all providers — it aborts and retries when a response stream produces no events for 5 minutes. Set CLAUDE_ENABLE_STREAM_WATCHDOG=0 to disable.
• Remote Control is now disabled when ANTHROPIC_BASE_URL points at a non-Anthropic host, matching the existing behavior under CLAUDE_CODE_USE_BEDROCK/_VERTEX/_FOUNDRY
• Changed opening the agents view from a foreground session to require a single ← press instead of two, matching the behavior in background sessions

2.1.195

• Added CLAUDE_CODE_DISABLE_MOUSE_CLICKS to disable mouse click/drag/hover in fullscreen mode while keeping wheel scroll
• Fixed hook matchers with hyphenated identifiers (e.g. code-reviewer, mcp__brave-search) accidentally substring-matching — they now exact-match. Use mcp__brave-search__.* to match all tools from a hyphenated MCP server.
• Fixed voice dictation on macOS capturing silence in long-running sessions after the default input device changes
• Fixed voice dictation auto-submit never firing for languages written without spaces (Japanese, Chinese, Thai)
• Fixed external plugins enabled only by project .claude/settings.json not requiring explicit install consent on every loader path
• Fixed /plugin Enable/Disable not working when a plugin's plugin.json name differs from its marketplace entry name
• Fixed background jobs disappearing from claude agents or losing data when written by a newer Claude Code version
• Fixed reopening a crashed background task showing a blank screen for up to 5 seconds instead of its restart
• Fixed background agent daemons running unreachable when the control socket fails to start, blocking restarts
• Improved voice mode on Linux: now distinguishes "no microphone" from "SoX not installed" when SoX is present but no audio capture device exists
• Improved claude agents completed list to fill available vertical space; on short terminals the header compacts so live sessions stay visible
• Improved Remote session startup with a provisioning checklist while the container starts

2.1.193

• Added autoMode.classifyAllShell setting to route all Bash/PowerShell commands through the auto-mode classifier instead of only arbitrary-code-execution patterns
• Added auto-mode denial reasons to the transcript, the denial toast, and /permissions recent denials
• Added claude_code.assistant_response OpenTelemetry log event containing the model's response text. Redacted unless OTEL_LOG_ASSISTANT_RESPONSES=1; when that var is unset it follows OTEL_LOG_USER_PROMPTS, so deployments that already log prompt content will start receiving response content on upgrade — set OTEL_LOG_ASSISTANT_RESPONSES=0 to keep prompts-only.
• Added live file path autocomplete to bash mode (!)
• Added a startup notice when MCP servers need authentication, pointing at /mcp
• Added automatic memory-pressure reaping for idle background shell commands (disable with CLAUDE_CODE_DISABLE_BG_SHELL_PRESSURE_REAP=1)
• Fixed /model and other client-data-gated UI showing stale/empty state immediately after /login
• Fixed backgrounding (←←) spuriously cancelling with "N background tasks would be abandoned" when all running tasks carry over to the new session
• Fixed pinned background agents being re-prompted to "Continue from where you left off" after every auto-update
• Fixed backgrounding the main turn spawning a phantom "general-purpose (resumed)" subagent that re-ran the main conversation
• Fixed agent panel hiding sibling agents when viewing a subagent
• Improved background agents: the launch result no longer instructs Claude to "end your response" — it keeps working on other tasks while the agent runs
• Improved MCP headersHelper auth: the helper now re-runs and reconnects automatically when a tool call returns 401/403
• Improved plugin auto-rename: marketplace renames maps are now followed automatically, updating your settings to the new name
• Improved /add-dir message when the directory is already a working directory
