+## Latest Features (January 2025)
+
+### 🚀 New `task-master start` Command
+
+**Automated Task Execution with Claude Code Integration**
+
+The new `start` command revolutionizes your development workflow by automatically launching Claude Code with comprehensive task context:
+
+```bash
+# Start a specific task
+task-master start 1.2
+
+# Start the next available task automatically
+task-master start
+
+# Preview what would be executed without launching Claude Code
+task-master start 1.2 --dry-run
+```
+
+**Key Features:**
+- **Automatic Task Discovery** - When no ID is provided, finds the next available task based on dependencies and status
+- **Rich Context Injection** - Provides Claude Code with task details, requirements, subtasks, and project context
+- **Status Management** - Automatically updates task status to "in-progress" when starting
+- **Flexible Options** - Support for dry-run, force mode, custom project paths, and JSON output
+
+### 🤖 Grok AI Provider Support
+
+**Enhanced AI Model Options**
+
+Task Master now supports xAI's Grok models with full 131K token capacity:
+
+```bash
+# Configure Grok as your main model
+task-master models --set-main grok-beta
+
+# Use Grok with vision capabilities
+task-master models --set-research grok-vision-beta
+```
+
