### Minor Changes

-   [#1599](https://github.com/eyaltoledano/claude-task-master/pull/1599) [`e689fcf`](https://github.com/eyaltoledano/claude-task-master/commit/e689fcf2a20cada4a19ee31fed723b6f35f2c13d) Thanks [@triepod-ai](https://github.com/triepod-ai)! - Add MCPB bundle for single-click Claude Desktop installation
    -   Added `manifest.json` for MCP Bundle (MCPB) specification v0.3
    -   Added `.mcpbignore` to exclude development files from bundle
    -   Added `icon.png` (512x512) for Claude Desktop display
    -   Enables users to install Task Master MCP server directly in Claude Desktop without manual configuration

-   [#1605](https://github.com/eyaltoledano/claude-task-master/pull/1605) [`efedc85`](https://github.com/eyaltoledano/claude-task-master/commit/efedc85cb1110a75748f3df0e530f3c9e27d2155) Thanks [@Crunchyman-ralph](https://github.com/Crunchyman-ralph)! - Add verbose output mode to loop command with `--verbose` flag
    -   New `-v, --verbose` flag shows Claude's work in real-time (thinking, tool calls) rather than waiting until the iteration completes
    -   New `--no-output` flag excludes full Claude output from iteration results to save memory
    -   Improved error handling with proper validation for incompatible options (verbose + sandbox)

-   [#1611](https://github.com/eyaltoledano/claude-task-master/pull/1611) [`c798639`](https://github.com/eyaltoledano/claude-task-master/commit/c798639d1a6b492de1b7cc82a28a13ddfba23eb8) Thanks [@Crunchyman-ralph](https://github.com/Crunchyman-ralph)! - Add optional `metadata` field to tasks for storing user-defined custom data

    Tasks and subtasks now support an optional `metadata` field that allows storing arbitrary JSON data such as:

    -   External IDs (GitHub issues, Jira tickets, Linear issues)
    -   Workflow data (sprints, story points, custom statuses)
    -   Integration data (sync timestamps, external system references)
    -   Custom tracking (UUIDs, version numbers, audit information)

    Key features:

    -   **AI-Safe**: Metadata is preserved through all AI operations (update-task, expand, etc.) because AI schemas intentionally exclude this field
    -   **Flexible Schema**: Store any JSON-serializable data without schema changes
    -   **Backward Compatible**: The field is optional; existing tasks work without modification
    -   **Subtask Support**: Both tasks and subtasks can have their own metadata
    -   **MCP Tool Support**: Use `update_task` and `update_subtask` with the `metadata` parameter to update metadata (requires `TASK_MASTER_ALLOW_METADATA_UPDATES=true` in MCP server environment)

    Example usage:

    ```json
    {
      "id": 1,
      "title": "Implement authentication",
      "metadata": {
        "githubIssue": 42,
        "sprint": "Q1-S3",
        "storyPoints": 5
      }
    }
    ```

    MCP metadata update example:

    ```javascript
    // With TASK_MASTER_ALLOW_METADATA_UPDATES=true set in MCP env
    update_task({
      id: "1",
      metadata: '{"githubIssue": 42, "sprint": "Q1-S3"}',
    });
    ```
