# Claude Code v2.0.72

> Claude Code v2.0.72, released 17 Dec 2025 (2025-12-17). 18 entries read out of the shipped bundle. Unofficial, and not affiliated with Anthropic.

Web version: https://changelogs.core-directive.com/v/2.0.72

This release adds a new `/mobile` command with QR codes to download the Claude mobile app, improves file indexing performance using `git ls-files`, introduces session indexing for faster conversation loading, and enhances multi-agent team workflows with improved teammate lifecycle management. The TodoWrite tool now shows a deprecation notice pointing to the new task management tools.

## Changes

### `/mobile` Command - Mobile App QR Codes

**What**

A new slash command that displays QR codes for downloading the Claude mobile app.

**Usage**

`/mobile` **Details** - Shows a QR code that links to the iOS App Store or Google Play Store - Use Tab or arrow keys to switch between iOS and Android - Press Escape or 'q' to close - Aliases: `/ios`, `/android` **Evidence** `s77()` at line 500313 (contains `"Show QR code to download the Claude mobile app"`, `mO0` object with App Store/Play Store URLs)

### Session Indexing [Gradual Rollout]

**What**

A new session indexing system that caches conversation metadata for faster session loading.

**Details**

- Creates a `sessions-index.json` file that caches session metadata
- Enables faster loading of conversation history without parsing all JSONL files
- Tracks session ID, message count, timestamps, branch info, and tags
- Feature-flagged behind `tengu_session_index`

**Evidence**

`icB()` at line 274892 (contains `"sessions-index.json"`, `tengu_session_index` flag check via `Vm1()`)

### Tool Search Beta Support

**What**

Adds the `tool-search-tool-2025-10-19` beta header for Vertex and Bedrock providers.

**Details**

- New beta feature flag added to the list of Claude betas
- Provider-specific version selection (different identifier for Vertex/Bedrock)

**Evidence**

`L4Q()` at line 64075 (contains `"tool-search-tool-2025-10-19"` beta string, checks `l4()` for provider)

### Marketplace Blocklist Support

**What**

Administrators can now block specific marketplace sources via policy settings.

**Details**

- New `blockedMarketplaces` policy setting to prevent installation from specific sources
- Supports blocking by source type: `github`, `git`, `url`, `npm`, `file`, `directory`
- Matches GitHub repos, git URLs, npm packages, and local paths
- Cross-format matching (e.g., SSH and HTTPS GitHub URLs treated as equivalent)

**Evidence**

`njA()` at line 279108 (contains `"blockedMarketplaces"`, `tU3()` for source matching logic)

### File Indexing with `git ls-files`

**What**

File indexing now uses `git ls-files` for significantly faster project file discovery in git repositories.

**Details**

- Uses `git ls-files --recurse-submodules` for tracked files
- Background fetches untracked files with `git ls-files --others`
- Falls back to ripgrep for non-git directories
- Respects `.ignore` and `.rgignore` files
- Caches results per working directory

**Evidence**

`fs5()` at line 447111 (contains `"git ls-files"`, `"getFilesUsingGit"` log messages, fallback to ripgrep)

### TodoWrite Deprecation Notice

**What**

The TodoWrite tool now displays a deprecation notice recommending the new task management tools.

**Details**

- Notice appears when using TodoWrite in team/multi-agent contexts
- Recommends: TaskCreate, TaskGet, TaskUpdate, TaskList
- The new tools support team collaboration, task dependencies, and persistent storage

**Evidence**

`Uj8` at line 190520 (contains `"DEPRECATED"`, lists `TaskCreate`, `TaskGet`, `TaskUpdate`, `TaskList`)

### Stable Channel Downgrade Dialog

**What**

When switching from beta/preview to stable channel, users now see a dialog if the stable version is older.

**Details**

- Prompts when stable version is lower than current version
- Options: "Allow downgrade to stable version" or "Stay on current version until stable catches up"
- Prevents accidental version downgrades

**Evidence**

`L59()` at line 489041 (contains `"Switch to Stable Channel"`, `"Allow downgrade to stable version"`)

### Settings Error Dialog

**What**

A new interactive dialog when settings files contain parse errors.

**Details**

- Shows which settings files have errors
- Warns that files with errors are skipped entirely
- Options: "Exit and fix manually" or "Continue without these settings"

**Evidence**

`ZK7()` at line 530828 (contains `"Settings Error"`, `"Files with errors are skipped entirely"`)

### Teammate Lifecycle Improvements

**What**

Better handling of teammate termination and task reassignment in multi-agent workflows.

**Details**

- When a teammate is terminated, open tasks assigned to them are automatically unassigned
- Leader receives notification with list of unassigned tasks
- Team-wide permission paths now propagate to teammates on initialization
- Teammates send idle notifications to leader when their Stop hook fires

**Evidence**

`De2()` at line 465299 (contains `"teammate_terminated"`, task unassignment logic), `ZJ1()` at line 389847 (contains `"TeammateInit"`, `"teamAllowedPaths"`)

### Invoked Skills Context

**What**

Skills invoked during a session are now tracked and can be included in system context.

**Details**

- Tracks skill name, path, content, and invocation time
- New `invoked_skills` message type for system context
- Skills sorted by most recent invocation

**Evidence**

`N65()` at line 377668 (contains `"invoked_skills"`, `BS0()` for skill tracking), `QS0()` at line 2443 (skill registration)

### Enhanced DOM Event System

**What**

Internal Ink rendering now uses a proper DOM event system with capturing and bubbling phases.

**Details**

- New `Dg` base event class with full event phase support
- Keyboard events (`PsA`), focus events (`pZA`), paste events (`qc1`), resize events (`Rc1`)
- Proper event propagation with `stopPropagation()` and `stopImmediatePropagation()`
- `eventTargetId` attribute tracking for event dispatch

**Evidence**

`Dg` class at line 169824, `Hg()` at line 169805 (event dispatch), `K$8()` at line 169776 (path building with capturing/bubbling)

### Tool Reference Filtering

**What**

Tool references in conversation history are now filtered when the referenced tool is no longer available.

**Details**

- Prevents errors when resuming sessions after tools have been removed
- Logs warning when filtering out unavailable tool references
- Replaces empty results with placeholder text

**Evidence**

`p97()` at line 483382 (contains `"Filtering out tool_reference for unavailable tool"`)

### Shell CWD Reset Warning Parsing

**What**

Shell output now properly parses and extracts CWD reset warnings.

**Details**

- Extracts "Shell cwd was reset to ..." messages from stderr
- Separates warning from actual error output for cleaner display

**Evidence**

`f17()` at line 460046 (contains `cwdResetWarning`, regex `Ks2` for `"Shell cwd was reset to"`)

### Bash Command Prefix Stripping

**What**

Bash tool now strips common command prefixes when analyzing commands.

**Details**

- Strips: `timeout`, `time`, `nice -n`, `nohup` prefixes
- Helps with command pattern matching and analysis

**Evidence**

`oO2()` at line 397353 (regex patterns for `timeout`, `time`, `nice`, `nohup`)

### Minimum Version Enforcement

**What**

Updates can now be blocked if they would install a version below the configured minimum.

**Details**

- Checks `minimumVersion` from version info before updating
- Logs skip message when update would go below minimum
- Helps prevent accidental downgrades in managed environments

**Evidence**

`SHA()` at line 523149 (contains `"minimumVersion"`, `"Skipping update to"`, `"below minimumVersion"`)

### BTW Side Questions [In Development]

**What**

Quick side questions that fork a conversation without using the main context.

**Status**

Stubbed - regex exists but parser always returns `{ isBtw: !1 }`

**Details**

- Intended syntax: Start message with "btw" to ask a quick question
- Would create a forked conversation for the side question
- Side questions cannot use tools
- UI component exists with "btw" label and "Answering..." spinner
- Full infrastructure exists but `vK1()` returns false

Orphaned Tip: ⚠️ Users may see: "Start with 'btw' to ask a quick side question without interrupting Claude's current work" - but the feature doesn't work yet.

**Evidence**

`vK1()` at line 451168 (returns `{ isBtw: !1, question: "" }`), `Ze5` regex at line 451196 (`/^btw\b/gi`), tip definition at line 472886 (`id: "btw-side-question"`, `isRelevant: !0` - always shows)

## Bug Fixes

- Fixed escaping of parentheses in tool rule content (`mJ7()`, `dJ7()`, `cM()` at line 519380 - proper handling of `\(` and `\)`)

## Notes

The new task management tools (TaskCreate, TaskGet, TaskUpdate, TaskList) are designed for multi-agent team workflows. If you're using TodoWrite in a team context, consider migrating to the new tools for better collaboration support.
