✨ What’s New in v0.14.2? ✨

We’re thrilled to announce the release of v0.14.2, packed with new features and critical enhancements. Here’s everything new in this update:

🚀 New Features

• Workflow Retry Functionality: We've enhanced workflow resilience with a retry feature by @zxhlyh. Your nodes will make repeat attempts if they face execution errors, minimizing disruptions.

• Order Support in Models: Now you can specify the order between text and files when using models like Gemini and Claude, thanks to the work of @laipz8200. This gives you precise control over data flow.

• Azure GPT-4o-2024-11-20 Model: Thanks to @agungbesti, this powerful model is now part of our lineup, offering advanced capabilities for your needs.

• Gemini-2.0-flash-thinking-exp-1219: Explore this cutting-edge model brought to you by @hjlarry—designed to enhance your application capabilities.

✨ Enhancements

• HTTP Request Node File Type Detection: Improved by @tancheng33 to ensure better handling of file uploads.

• Memory Optimization: Reduced memory usage from 800+ MB to 500+ MB, thanks to the optimizations by @yihong0618.

• Partial Success Status in App Logs: With the help of @Nov1c444, we’ve introduced a new log metric to capture partial successes across app operations.

• Workflow Parallel Depth Limit Configuration: Gain more control over concurrency in your workflows with this new setting by @laipz8200.

We owe a huge thank you to all the contributors for their hard work and dedication. Your continuous support and input drive our improvement.

As always, keep the feedback coming, and happy building with Dify! 🚀
