 # Changelog
 
+## 0.1.1
+
+### Features
+
+- **Minimum Claude Code version check**: Added version validation to ensure Claude Code 2.0.0+ is installed. The SDK will display a warning if an older version is detected, helping prevent compatibility issues
+- **Updated PermissionResult types**: Aligned permission result types with the latest control protocol for better type safety and compatibility
+
+### Improvements
+
+- **Model references**: Updated all examples and tests to use the simplified `claude-sonnet-4-5` model identifier instead of dated version strings
+
 ## 0.1.0
 
 Introducing the Claude Agent SDK! The Claude Code SDK has been renamed to better reflect its capabilities for building AI agents across all domains, not just coding.
 
 ### Breaking Changes
 
 #### Type Name Changes
+
 - **ClaudeCodeOptions renamed to ClaudeAgentOptions**: The options type has been renamed to match the new SDK branding. Update all imports and type references:
+
   ```python
   # Before
   from claude_agent_sdk import query, ClaudeCodeOptions

 #### System Prompt Changes
+
 - **Merged prompt options**: The `custom_system_prompt` and `append_system_prompt` fields have been merged into a single `system_prompt` field for simpler configuration
 - **No default system prompt**: The Claude Code system prompt is no longer included by default, giving you full control over agent behavior. To use the Claude Code system prompt, explicitly set:
   ```python
   system_prompt={"type": "preset", "preset": "claude_code"}
   ```
 
 #### Settings Isolation
+
 - **No filesystem settings by default**: Settings files (`settings.json`, `CLAUDE.md`), slash commands, and subagents are no longer loaded automatically. This ensures SDK applications have predictable behavior independent of local filesystem configurations
 - **Explicit settings control**: Use the new `setting_sources` field to specify which settings locations to load: `["user", "project", "local"]`
