# Changelog
All notable changes to this project will be documented in this file.
## [0.5.0] - 2025-11-11
### Breaking Changes
**LangChain Upgrade: 0.3.3 → 0.4.0**
This release upgrades the LangChain dependency from 0.3.3 to 0.4.0, which introduces breaking changes in how LLM responses are handled.
#### What Changed
- **Message Content Structure**: LangChain 0.4.0 returns message content as a list of `ContentPart` structs instead of plain strings
- Before: `%Message{content: "text response"}`
- After: `%Message{content: [%ContentPart{type: :text, content: "text response"}]}`
- The library now automatically converts this using `ContentPart.parts_to_string/1`
#### Model Support Changes
LangChain 0.4.0 officially supports only the following LLM providers:
- ✅ **OpenAI ChatGPT** - Fully supported
- ✅ **Anthropic Claude** - Fully supported
- ✅ **Google Gemini** - Fully supported
- ✅ **Google Vertex AI** - Fully supported
- ❌ **Other models** - May not work with LangChain 0.4.0
**Important**: If you're using ChatOllamaAI or other unsupported models, they may not function correctly with this version. We recommend:
1. Testing your specific model after upgrading
2. Using one of the officially supported providers
3. Implementing a custom adapter if needed
4. Staying on version 0.4.5 if you require unsupported models
#### Migration Notes
If you're upgrading from 0.4.5 to 0.5.0:
1. **No configuration changes required** - Your existing configuration will continue to work
2. **Test your LLM provider** - Verify translations work with your chosen provider
3. **Check the updated README** - New examples added for Anthropic Claude, Google Gemini, and custom endpoints
### Added
- Support for Anthropic Claude via `LangChain.ChatModels.ChatAnthropic`
- Support for Google Gemini via `LangChain.ChatModels.ChatGoogleAI`
- Comprehensive documentation for custom remote LLM endpoints

### Changed
- Updated LangChain dependency from 0.3.3 to ~> 0.4.0
- Modified message content handling to support new ContentPart structure
- Updated README with additional provider examples and custom endpoint configuration
### Technical Details
The `translate/2` function in `GettextTranslator.Processor.LLM` now:
- Pattern matches on `{:ok, %{last_message: %Message{content: content}}}`
- Converts ContentPart list to string using `ContentPart.parts_to_string/1`
- Maintains backward compatibility with existing configurations
