# Changelog

## 2.1.116

- `/resume` on large sessions is significantly faster (up to 67% on 40MB+ sessions) and handles sessions with many dead-fork entries more efficiently
- Faster MCP startup when multiple stdio servers are configured; `resources/templates/list` is now deferred to first `@`-mention
- Smoother fullscreen scrolling in VS Code, Cursor, and Windsurf terminals — `/terminal-setup` now configures the editor's scroll sensitivity
- Thinking spinner now shows progress inline ("still thinking", "thinking more", "almost done thinking"), replacing the separate hint row
- `/config` search now matches option values (e.g. searching "vim" finds the Editor mode setting)
- `/doctor` can now be opened while Claude is responding, without waiting for the current turn to finish
- `/reload-plugins` and background plugin auto-update now auto-install missing plugin dependencies from marketplaces you've already added
- Bash tool now surfaces a hint when `gh` commands hit GitHub's API rate limit, so agents can back off instead of retrying

- Fixed Devanagari and other Indic scripts rendering with broken column alignment in the terminal UI
- Fixed Ctrl+- not triggering undo in terminals using the Kitty keyboard protocol (iTerm2, Ghostty, kitty, WezTerm, Windows Terminal)
- Fixed Cmd+Left/Right not jumping to line start/end in terminals that use the Kitty keyboard protocol (Warp fullscreen, kitty, Ghostty, WezTerm)
- Fixed Ctrl+Z hanging the terminal when Claude Code is launched via a wrapper process (e.g. `npx`, `bun run`)
- Fixed scrollback duplication in inline mode where resizing the terminal or large output bursts would repeat earlier conversation history
- Fixed modal search dialogs overflowing the screen at short terminal heights, hiding the search box and keyboard hints
- Fixed scattered blank cells and disappearing composer chrome in the VS Code integrated terminal during scrolling
- Fixed an intermittent API 400 error related to cache control TTL ordering that could occur when a parallel request completed during request setup

- Remote Control clients can now query `@`-file autocomplete suggestions
- Improved `/ultrareview`: faster launch with parallelized checks, diffstat in the launch dialog, and animated launching state
- Subagents that stall mid-stream now fail with a clear error after 10 minutes instead of hanging silently
- Bash tool: multi-line commands whose first line is a comment now show the full command in the transcript, closing a UI-spoofing vector
- Running `cd <current-directory> && git …` no longer triggers a permission prompt when the `cd` is a no-op
- Security: on macOS, `/private/{etc,var,tmp,home}` paths are now treated as dangerous removal targets under `Bash(rm:*)` allow rules
- Security: Bash deny rules now match commands wrapped in `env`/`sudo`/`watch`/`ionice`/`setsid` and similar exec wrappers

## 2.1.111

- Claude Opus 4.7 xhigh is now available! Use /effort to tune speed vs. intelligence
- Auto mode is now available for Max subscribers when using Opus 4.7
- Added `xhigh` effort level for Opus 4.7, sitting between `high` and `max`. Available via `/effort`, `--effort`, and the model picker; other models fall back to `high`
- `/effort` now opens an interactive slider when called without arguments, with arrow-key navigation between levels and Enter to confirm
- Added "Auto (match terminal)" theme option that matches your terminal's dark/light mode — select it from `/theme`
- Added `/less-permission-prompts` skill — scans transcripts for common read-only Bash and MCP tool calls and proposes a prioritized allowlist for `.claude/settings.json`
- Added `/ultrareview` for running comprehensive code review in the cloud using parallel multi-agent analysis and critique — invoke with no arguments to review your current branch, or `/ultrareview <PR#>` to fetch and review a specific GitHub PR
- Auto mode no longer requires `--enable-auto-mode`
- Windows: PowerShell tool is progressively rolling out. Opt in or out with `CLAUDE_CODE_USE_POWERSHELL_TOOL`. On Linux and macOS, enable with `CLAUDE_CODE_USE_POWERSHELL_TOOL=1` (requires `pwsh` on PATH)
- Read-only bash commands with glob patterns (e.g. `ls *.ts`) and commands starting with `cd <project-dir> &&` no longer trigger a permission prompt
- Suggest the closest matching subcommand when `claude <word>` is invoked with a near-miss typo (e.g. `claude udpate` → "Did you mean `claude update`?")
- Plan files are now named after your prompt (e.g. `fix-auth-race-snug-otter.md`) instead of purely random words
- Improved `/setup-vertex` and `/setup-bedrock` to show the actual `settings.json` path when `CLAUDE_CONFIG_DIR` is set, seed model candidates from existing pins on re-run, and offer a "with 1M context" option for supported models
- `/skills` menu now supports sorting by estimated token count — press `t` to toggle
- `Ctrl+U` now clears the entire input buffer (previously: delete to start of line); press `Ctrl+Y` to restore
- `Ctrl+L` now forces a full screen redraw in addition to clearing the prompt input
- Transcript view footer now shows `[` (dump to scrollback) and `v` (open in editor) shortcuts
- The "+N lines" marker for truncated long pastes is now a full-width rule for easier scanning
- Headless `--output-format stream-json` now includes `plugin_errors` on the init event when plugins are demoted for unsatisfied dependencies
- Added `OTEL_LOG_RAW_API_BODIES` environment variable to emit full API request and response bodies as OpenTelemetry log events for debugging
- Suppressed spurious decompression, network, and transient error messages that could appear in the TUI during normal operation
- Reverted the v2.1.110 cap on non-streaming fallback retries — it traded long waits for more outright failures during API overload
- Fixed terminal display tearing (random characters, drifting input) in iTerm2 + tmux setups when terminal notifications are sent
- Fixed `@` file suggestions re-scanning the entire project on every turn in non-git working directories, and showing only config files in freshly-initialized git repos with no tracked files
- Fixed LSP diagnostics from before an edit appearing after it, causing the model to re-read files it just edited
- Fixed tab-completing `/resume` immediately resuming an arbitrary titled session instead of showing the session picker
- Fixed `/context` grid rendering with extra blank lines between rows
- Fixed `/clear` dropping the session name set by `/rename`, causing statusline output to lose `session_name`
- Improved plugin error handling: dependency errors now distinguish conflicting, invalid, and overly complex version requirements; fixed stale resolved versions after `plugin update`; `plugin install` now recovers from interrupted prior installs
- Fixed Claude calling a non-existent `commit` skill and showing "Unknown skill: commit" for users without a custom `/commit` command
- Fixed 429 rate-limit errors on Bedrock/Vertex/Foundry referencing status.claude.com (it only covers Anthropic-operated providers)
- Fixed feedback surveys appearing back-to-back after dismissing one
- Fixed bare URLs in bash/PowerShell/MCP tool output being unclickable when the terminal wraps them across lines
- Windows: `CLAUDE_ENV_FILE` and SessionStart hook environment files now apply (previously a no-op)
- Windows: permission rules with drive-letter paths are now correctly root-anchored, and paths differing only by drive-letter case are recognized as the same path

## 2.1.110

- Added `autoScrollEnabled` config to disable conversation auto-scroll in fullscreen mode
- Added option to show Claude's last response as commented context in the `Ctrl+G` external editor (enable via `/config`)

## 2.1.109

- Improved the extended-thinking indicator with a rotating progress hint

## 2.1.108

- Added `ENABLE_PROMPT_CACHING_1H` env var to opt into 1-hour prompt cache TTL on API key, Bedrock, Vertex, and Foundry (`ENABLE_PROMPT_CACHING_1H_BEDROCK` is deprecated but still honored), and `FORCE_PROMPT_CACHING_5M` to force 5-minute TTL
- Added recap feature to provide context when returning to a session, configurable in `/config` and manually invocable with `/recap`; force with `CLAUDE_CODE_ENABLE_AWAY_SUMMARY` if telemetry disabled.
- The model can now discover and invoke built-in slash commands like `/init`, `/review`, and `/security-review` via the Skill tool
- `/undo` is now an alias for `/rewind`
- Improved `/model` to warn before switching models mid-conversation, since the next response re-reads the full history uncached
- Improved `/resume` picker to default to sessions from the current directory; press `Ctrl+A` to show all projects
- Improved error messages: server rate limits are now distinguished from plan usage limits; 5xx/529 errors show a link to status.claude.com; unknown slash commands suggest the closest match
- Reduced memory footprint for file reads, edits, and syntax highlighting by loading language grammars on demand
- Added "verbose" indicator when viewing the detailed transcript (`Ctrl+O`)

- Fixed Remote Control session titles set in the web UI being overwritten by auto-generated titles after the third message
- Fixed `--resume` truncating sessions when the transcript contained a self-referencing message
- Fixed transcript write failures (e.g., disk full) being silently dropped instead of being logged
- Fixed diacritical marks (accents, umlauts, cedillas) being dropped from responses when the `language` setting is configured

- Improved `/doctor` layout with status icons; press `f` to have Claude fix reported issues
- Improved `/config` labels and descriptions for clarity
- Improved skill description handling: raised the listing cap from 250 to 1,536 characters and added a startup warning when descriptions are truncated

- Fixed screen going blank when the prompt input wraps to a second line in long conversations
- Fixed leading whitespace getting copied when selecting multi-line assistant responses in fullscreen mode
- Fixed leading whitespace being trimmed from assistant messages, breaking ASCII art and indented diagrams
- Fixed garbled bash output when commands print clickable file links (e.g. Python `rich`/`loguru` logging)

## 2.1.101

- Added `/team-onboarding` command to generate a teammate ramp-up guide from your local Claude Code usage
- Added OS CA certificate store trust by default, so enterprise TLS proxies work without extra setup (set `CLAUDE_CODE_CERT_STORE=bundled` to use only bundled CAs)
- `/ultraplan` and other remote-session features now auto-create a default cloud environment instead of requiring web setup first
- Improved brief mode to retry once when Claude responds with plain text instead of a structured message

- Fixed a hardcoded 5-minute request timeout that aborted slow backends (local LLMs, extended thinking, slow gateways) regardless of `API_TIMEOUT_MS`
- Fixed `permissions.deny` rules not overriding a PreToolUse hook's `permissionDecision: "ask"` — previously the hook could downgrade a deny into a prompt
- Fixed `--setting-sources` without `user` causing background cleanup to ignore `cleanupPeriodDays` and delete conversation history older than 30 days
- Fixed Bedrock SigV4 authentication failing with 403 when `ANTHROPIC_AUTH_TOKEN`, `apiKeyHelper`, or `ANTHROPIC_CUSTOM_HEADERS` set an Authorization header

- Fixed Grep tool ENOENT when the embedded ripgrep binary path becomes stale (VS Code extension auto-update, macOS App Translocation); now falls back to system `rg` and self-heals mid-session
- Fixed `/btw` writing a copy of the entire conversation to disk on every use
- Fixed `/context` Free space and Messages breakdown disagreeing with the header percentage
- Fixed several plugin issues: slash commands resolving to the wrong plugin with duplicate `name:` frontmatter, `/plugin update` failing with `ENAMETOOLONG`, Discover showing already-installed plugins, directory-source plugins loading from a stale version cache, and skills not honoring `context: fork` and `agent` frontmatter fields
- Fixed the `/mcp` menu offering OAuth-specific actions for MCP servers configured with `headersHelper`; Reconnect is now offered instead to re-invoke the helper script
- Fixed `ctrl+]`, `ctrl+\`, and `ctrl+^` keybindings not firing in terminals that send raw C0 control bytes (Terminal.app, default iTerm2, xterm)
- Fixed `/login` OAuth URL rendering with padding that prevented clean mouse selection
- Fixed rendering issues: flicker in non-fullscreen mode when content above the visible area changed, terminal scrollback being wiped during long sessions in non-fullscreen mode, and mouse-scroll escape sequences occasionally leaking into the prompt as text

- Fixed `/insights` sometimes omitting the report file link from its response
- [VSCode] Fixed the file attachment below the chat input not clearing when the last editor tab is closed

## 2.1.98

- Added interactive Google Vertex AI setup wizard accessible from the login screen when selecting "3rd-party platform", guiding you through GCP authentication, project and region configuration, credential verification, and model pinning

- VSCode: Added `vscode://anthropic.claude-code/open` URI handler to open a new Claude Code tab programmatically, with optional `prompt` and `session` query parameters

## 2.1.71

- Added `/loop` command to run a prompt or slash command on a recurring interval (e.g. `/loop 5m check the deploy`)
- Added cron scheduling tools for recurring prompts within a session
- Added `voice:pushToTalk` keybinding to make the voice activation key rebindable in `keybindings.json` (default: space) — modifier+letter combos like `meta+k` have zero typing interference
- Added `fmt`, `comm`, `cmp`, `numfmt`, `expr`, `test`, `printf`, `getconf`, `seq`, `tsort`, and `pr` to the bash auto-approval allowlist
- Fixed stdin freeze in long-running sessions where keystrokes stop being processed but the process stays alive
- Fixed a 5–8 second startup freeze for users with voice mode enabled, caused by CoreAudio initialization blocking the main thread after system wake
- Fixed startup UI freeze when many claude.ai proxy connectors refresh an expired OAuth token simultaneously
- Fixed forked conversations (`/fork`) sharing the same plan file, which caused plan edits in one fork to overwrite the other
- Fixed the Read tool putting oversized images into context when image processing failed, breaking subsequent turns in long image-heavy sessions
- Fixed false-positive permission prompts for compound bash commands containing heredoc commit messages
- Fixed plugin installations being lost when running multiple Claude Code instances
- Fixed claude.ai connectors failing to reconnect after OAuth token refresh
- Fixed claude.ai MCP connector startup notifications appearing for every org-configured connector instead of only previously connected ones
- Fixed background agent completion notifications missing the output file path, which made it difficult for parent agents to recover agent results after context compaction
- Fixed duplicate output in Bash tool error messages when commands exit with non-zero status
- Fixed Chrome extension auto-detection getting permanently stuck on "not installed" after running on a machine without local Chrome
- Fixed `/plugin marketplace update` failing with merge conflicts when the marketplace is pinned to a branch/tag ref
- Fixed `/plugin marketplace add owner/repo@ref` incorrectly parsing `@` — previously only `#` worked as a ref separator, causing undiagnosable errors with `strictKnownMarketplaces`
- Fixed duplicate entries in `/permissions` Workspace tab when the same directory is added with and without a trailing slash
- Fixed `--print` hanging forever when team agents are configured — the exit loop no longer waits on long-lived `in_process_teammate` tasks
- Fixed "❯ Tool loaded." appearing in the REPL after every `ToolSearch` call
- Fixed prompting for `cd <cwd> && git ...` on Windows when the model uses a mingw-style path
- Improved startup time by deferring native image processor loading to first use
- Improved bridge session reconnection to complete within seconds after laptop wake from sleep, instead of waiting up to 10 minutes
- Improved `/plugin uninstall` to disable project-scoped plugins in `.claude/settings.local.json` instead of modifying `.claude/settings.json`, so changes don't affect teammates
- Improved plugin-provided MCP server deduplication — servers that duplicate a manually-configured server (same command/URL) are now skipped, preventing duplicate connections and tool sets. Suppressions are shown in the `/plugin` menu.
- Updated `/debug` to toggle debug logging on mid-session, since debug logs are no longer written by default
- Removed startup notification noise for unauthenticated org-registered claude.ai connectors

## 2.1.70

- Fixed API 400 errors when using `ANTHROPIC_BASE_URL` with a third-party gateway — tool search now correctly detects proxy endpoints and disables `tool_reference` blocks
- Fixed `API Error: 400 This model does not support the effort parameter` when using custom Bedrock inference profiles or other model identifiers not matching standard Claude naming patterns
- Fixed empty model responses immediately after `ToolSearch` — the server renders tool schemas with system-prompt-style tags at the prompt tail, which could confuse models into stopping early
- Fixed prompt-cache bust when an MCP server with `instructions` connects after the first turn
- Fixed Enter inserting a newline instead of submitting when typing over a slow SSH connection
- Fixed clipboard corrupting non-ASCII text (CJK, emoji) on Windows/WSL by using PowerShell `Set-Clipboard`

- Fixed plugins showing "not found in marketplace" errors on fresh startup by auto-refreshing after marketplace installation
- Fixed `/security-review` command failing with `unknown option merge-base` on older git versions
- Fixed `/color` command having no way to reset back to the default color — `/color default`, `/color gray`, `/color reset`, and `/color none` now restore the default
- Fixed a performance regression in the `AskUserQuestion` preview dialog that re-ran markdown rendering on every keystroke in the notes input
- Fixed feature flags read during early startup never refreshing their disk cache, causing stale values to persist across sessions
- Fixed `permissions.defaultMode` settings values other than `acceptEdits` or `plan` being applied in Claude Code Remote environments — they are now ignored
- Fixed skill listing being re-injected on every `--resume` (~600 tokens saved per resume)
- Fixed teleport marker not rendering in VS Code teleported sessions
- Improved error message when microphone captures silence to distinguish from "no speech detected"
- Improved compaction to preserve images in the summarizer request, allowing prompt cache reuse for faster and cheaper compaction
- Improved `/rename` to work while Claude is processing, instead of being silently queued
- Reduced prompt input re-renders during turns by ~74%
- Reduced startup memory by ~426KB for users without custom CA certificates
- Reduced Remote Control `/poll` rate to once per 10 minutes while connected (was 1–2s), cutting server load ~300×. Reconnection is unaffected — transport loss immediately wakes fast polling.
- [VSCode] Added spark icon in VS Code activity bar that lists all Claude Code sessions, with sessions opening as full editors
- [VSCode] Added full markdown document view for plans in VS Code, with support for adding comments to provide feedback
- [VSCode] Added native MCP server management dialog — use `/mcp` in the chat panel to enable/disable servers, reconnect, and manage OAuth authentication without switching to the terminal

- Fixed `--model claude-opus-4-0` and `--model claude-opus-4-1` resolving to deprecated Opus versions instead of current
- Fixed macOS keychain corruption when using multiple OAuth MCP servers. Large OAuth metadata blobs could overflow the `security -i` stdin buffer, silently leaving stale credentials behind and causing repeated `/login` prompts.
- Fixed `.credentials.json` losing `subscriptionType` (showing "Claude API" instead of "Claude Pro"/"Claude Max") when the profile endpoint transiently fails during token refresh (anthropics/claude-code#30185)
- Fixed ghost dotfiles (`.bashrc`, `HEAD`, etc.) appearing as untracked files in the working directory after sandboxed Bash commands on Linux

- Fixed "unexpected tool_use_id found in tool_result blocks" error when resuming conversations that start with an orphaned tool result
- Fixed teammates accidentally spawning nested teammates via the Agent tool's `name` parameter
- Fixed `CLAUDE_CODE_MAX_OUTPUT_TOKENS` being ignored during conversation compaction
- Fixed `/compact` summary rendering as a user bubble in SDK consumers (Claude Code Remote web UI, VSCode extension)
- Fixed voice space bar getting stuck after a failed voice activation (module loading race, cold GrowthBook)
- Fixed worktree file copy on Windows
- Fixed global `.claude` folder detection on Windows
- Fixed symlink bypass where writing new files through a symlinked parent directory could escape the working directory in `acceptEdits` mode
- Fixed sandbox prompting users to approve non-allowed domains when `allowManagedDomainsOnly` is enabled in managed settings — non-allowed domains are now blocked automatically with no bypass
- Fixed interactive tools (e.g., `AskUserQuestion`) being silently auto-allowed when listed in a skill's allowed-tools, bypassing the permission prompt and running with empty answers
- Fixed multi-GB memory spike when committing with large untracked binary files in the working tree
- Fixed Escape not interrupting a running turn when the input box has draft text. Use Up arrow to pull queued messages back for editing, or Ctrl+U to clear the input line.
- Fixed Android app crash when running local slash commands (`/voice`, `/cost`) in Remote Control sessions
- Fixed a memory leak where old message array versions accumulated in React Compiler `memoCache` over long sessions
- Fixed a memory leak where REPL render scopes accumulated over long sessions (~35MB over 1000 turns)

- Fixed hang when `--mcp-config` points to a corrupted file
- Fixed slow startup when many skills/plugins are installed
- Fixed `cd <outside-dir> && <cmd>` permission prompt to surface the chained command instead of only showing "Yes, allow reading from <dir>/"

- Improved UI rendering performance in native binaries with React Compiler
- Improved `--worktree` startup by eliminating a git subprocess on the startup path
- Improved macOS startup by eliminating redundant settings-file reloads when managed settings resolve
- Improved macOS startup for Claude.ai enterprise/team users by skipping an unnecessary keychain lookup
- Improved MCP `-p` startup by pipelining claude.ai config fetch with local connections and using a concurrency pool instead of sequential batching
- Improved voice startup by removing imperceptible warmup pulse animations that were causing re-render stutter
- Improved MCP binary content handling: tools returning PDFs, Office documents, or audio now save decoded bytes to disk with the correct file extension instead of dumping raw base64 into the conversation context. WebFetch also saves binary responses alongside its summary.

- Improved LSP tool rendering and memory context building to no longer read entire files
- Improved session upload and memory sync to avoid reading large files into memory before size/binary checks
- Improved file operation performance by avoiding reading file contents for existence checks (6 sites)

- [VSCode] Added compaction display as a collapsible "Compacted chat" card with the summary inside
- [VSCode] The permission mode picker now respects `permissions.disableBypassPermissionsMode` from your effective Claude Code settings (including managed/policy settings) — when set to `disable`, bypass permissions mode is hidden from the picker
- [VSCode] Fixed RTL text (Arabic, Hebrew, Persian) rendering reversed in the chat panel (regression in v2.1.63)

## 2.1.68

- Opus 4.6 now defaults to medium effort for Max and Team subscribers. Medium effort works well for most tasks — it's the sweet spot between speed and thoroughness. You can change this anytime with `/model`
- Re-introduced the "ultrathink" keyword to enable high effort for the next turn
- Removed Opus 4 and 4.1 from Claude Code on the first-party API — users with these models pinned are automatically moved to Opus 4.6

- Fixed memory leak where long-running teammates retained all messages in AppState even after conversation compaction
- Fixed a memory leak where MCP server fetch caches were not cleared on disconnect, causing growing memory usage with servers that reconnect frequently
- Improved memory usage in long sessions with subagents by stripping heavy progress message payloads during context compaction
- Added "Always copy full response" option to the `/copy` picker. When selected, future `/copy` commands will skip the code block picker and copy the full response directly.
- VSCode: Added session rename and remove actions to the sessions list
- Fixed `/clear` not resetting cached skills, which could cause stale skill content to persist in the new conversation

## 2.1.62

- Improved ordering of short task lists
- Improved memory usage in multi-agent sessions by releasing completed subagent task state
- Fixed MCP OAuth token refresh race condition when running multiple Claude Code instances simultaneously

## 2.1.56

- VS Code: Fixed another cause of "command 'claude-vscode.editor.openLast' not found" crashes

## 2.1.55

- Fixed BashTool failing on Windows with EINVAL error

## 2.1.53

- Fixed a UI flicker where user input would briefly disappear after submission before the message rendered

- Fixed a security issue where `statusLine` and `fileSuggestion` hook commands could execute without workspace trust acceptance in interactive mode.
- Tool results larger than 50K characters are now persisted to disk (previously 100K). This reduces context window usage and improves conversation longevity.
- Fixed a bug where duplicate `control_response` messages (e.g. from WebSocket reconnects) could cause API 400 errors by pushing duplicate assistant messages into the conversation.
- Added `CLAUDE_CODE_ACCOUNT_UUID`, `CLAUDE_CODE_USER_EMAIL`, and `CLAUDE_CODE_ORGANIZATION_UUID` environment variables for SDK callers to provide account info synchronously, eliminating a race condition where early telemetry events lacked account metadata.
- Fixed slash command autocomplete crashing when a plugin's SKILL.md description is a YAML array or other non-string type
- The `/model` picker now shows human-readable labels (e.g., "Sonnet 4.5") instead of raw model IDs for pinned model versions, with an upgrade hint when a newer version is available.

- Permission suggestions are now populated when safety checks trigger an ask response, enabling SDK consumers to display permission options
- Sonnet 4.5 with 1M context is being removed from the Max plan in favor of our frontier Sonnet 4.6 model, which now has 1M context. Please switch in /model.
- Fixed verbose mode not updating thinking block display when toggled via `/config` — memo comparators now correctly detect verbose changes
- Fixed unbounded WASM memory growth during long sessions by periodically resetting the tree-sitter parser
- Fixed potential rendering issues caused by stale yoga layout references
- Improved performance in non-interactive mode (`-p`) by skipping unnecessary API calls during startup

- Fixed unbounded memory growth during long-running sessions caused by Yoga WASM linear memory never shrinking
- SDK model info now includes `supportsEffort`, `supportedEffortLevels`, and `supportsAdaptiveThinking` fields so consumers can discover model capabilities.
- Added `ConfigChange` hook event that fires when configuration files change during a session, enabling enterprise security auditing and optional blocking of settings changes.
- Improved startup performance by caching MCP auth failures to avoid redundant connection attempts
- Improved startup performance by reducing HTTP calls for analytics token counting
- Improved startup performance by batching MCP tool token counting into a single API call
- Fixed `disableAllHooks` setting to respect managed settings hierarchy — non-managed settings can no longer disable managed hooks set by policy (#26637)
- Fixed `--resume` session picker showing raw XML tags for sessions that start with commands like `/clear`. Now correctly falls through to the session ID fallback.
- Improved permission prompts for path safety and working directory blocks to show the reason for the restriction instead of a bare prompt with no context

## 2.1.47

- Fixed FileWriteTool line counting to preserve intentional trailing blank lines instead of stripping them with `trimEnd()`.
- Fixed Windows terminal rendering bugs caused by `os.EOL` (`\r\n`) in display code — line counts now show correct values instead of always showing 1 on Windows.
- Improved VS Code plan preview: auto-updates as Claude iterates, enables commenting only when the plan is ready for review, and keeps the preview open when rejecting so Claude can revise.
- Fixed a bug where bold and colored text in markdown output could shift to the wrong characters on Windows due to `\r\n` line endings.
- Fixed compaction failing when conversation contains many PDF documents by stripping document blocks alongside images before sending to the compaction API (anthropics/claude-code#26188)

- Windows: Fixed CWD tracking temp files never being cleaned up, causing them to accumulate indefinitely (anthropics/claude-code#17600)
- Use `ctrl+f` to kill all background agents instead of double-pressing ESC. Background agents now continue running when you press ESC to cancel the main thread, giving you more control over agent lifecycle.
- Fixed API 400 errors ("thinking blocks cannot be modified") that occurred in sessions with concurrent agents, caused by interleaved streaming content blocks preventing proper message merging.
- Simplified teammate navigation to use only Shift+Down (with wrapping) instead of both Shift+Up and Shift+Down.
- Fixed an issue where a single file write/edit error would abort all other parallel file write/edit operations. Independent file mutations now complete even when a sibling fails.
- Added `last_assistant_message` field to Stop and SubagentStop hook inputs, providing the final assistant response text so hooks can access it without parsing transcript files.
- Fixed custom session titles set via `/rename` being lost after resuming a conversation (anthropics/claude-code#23610)
- Fixed collapsed read/search hint text overflowing on narrow terminals by truncating from the start.
