# 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
