🚀 What’s New in v0.13.0? 🚀

Hey there, update seekers! Welcome to version 0.13.0. We’ve packed a lot of goodies in this release, from fixes and feature upgrades to some nice behind-the-scenes refactoring. Here's the scoop:

✨ New Features

• Variable Assigner Node Update
  The Variable Assigner node now supports several powerful features to streamline workflows:
  • Operations on multiple conversation variables in a single node.
  • Extend operator to link two arrays seamlessly.
  • Set operator to assign constants to variables directly.

  

  📄 Read the full documentation

• Github DSL URL Support
  You can now use github.com links directly for DSLs instead of relying on raw.githubusercontent.com. This makes integration smoother and more intuitive. Thanks to @yihong0618 in #11125.

• VTT File Support
  Document Extractor can now handle VTT files for all your subtitle extraction needs. Big thanks to @fujita-h in #11148.

• Conversational Opener Upgrade
  More opening questions for your conversations, increasing engagement points. Thanks to @fujita-h in #11233.

🛠️ Improvements and Fixes

• LLM Invoke Errors
  Reduced noise from unnecessary exceptions—LLM node invoke errors will no longer recorded in the logs. Thanks to @laipz8200 in #11141.

• Parameter Type Fix
  Resolved an issue with the parameter extractor function that expected a string and wasn't given one. Kudos to @charli117 in #11142.

• ToolInvokeMessage Validation Fix
  Fixed validation errors for ToolInvokeMessages when the blob_message meta is missing. Thanks to @catusax in #11212.

• Claude Handling
  Claude can now handle empty strings gracefully. Thanks to @yihong0618 in #11238.

• Redis Port Double Split Fix
  Adjusted the Redis port handling logic to address double-split issues. Thanks to @yihong0618 in #11270.

• Modular App Features
  Reorganized app features into modular components for improved scalability and development ease. Shoutout to @bowenliang123 in #9129.

That’s the short version, but as always, there’s plenty more in the logs for those who like a deep dive. Update your systems and take these features for a spin. Keep building, keep exploring, and stay tuned for more!
