✨ What’s New in v0.15.0? ✨

Hey developers! We know you've got a lot going on, so let's cut to it. Here's what's new in v0.15.0, our latest release, packed with bug fixes, feature upgrades, and enhancements.

⚡ New Features

🧑‍🧑‍🧒‍🧒 Parent-child Retrieval

Leverage a two-tier hierarchical approach that effectively balances the trade-off between accurate matching and comprehensive contextual information to improve the quality and accuracy of AI-generated responses in RAG systems. Learn more

Highlights:

  • The new chunk editing and preview display brings users a better reading and editing experience, making it easier for people without technical backgrounds to understand the two-layer parent-child structure.
  • We allow users to improve retrieval efficiency by child chunks independently without changing parent chunks as LLM content.
  • Update index mode rules: Economical cannot be downgraded once upgraded to High Quality.
  • Document batch operations in Knowledge Base support batch enabling, disabling, deletion, and archiving document functions.

✨ Improvements

  • Multi-Version Workflows: Manage multiple workflow versions more effectively with contributions from @warren830 (#11990).
  • UI/UX adjustments for accessibility, such as replacing div with button to enhance user interaction and navigation (@TinsFox, #12046).
  • Database and memory optimizations that not only improve performance but they'll likely save you headaches when loading and retrieving data (@laipz8200, #12071).
  • Enhanced support for streaming modes, error feedback, and token handling to improve your coding life significantly (various contributors).

🛠️ Fixes

  • Numerous typo fixes, improved error handling, and bug resolutions across the workflow, such as tool can not run, HTTP method case sensitivity by @yihong0618 (#12054, #12401), and cleaning up exceptions by @acelyc111 (#12246). Your workflow should be a lot smoother now.
  • Improved error management in several components. This includes better handling of invalid URLs, file uploads, JSON parsing, and missing IDs, thanks to contributions from @laipz8200 (various PRs).
  • Default value fixes to configurations like Google Storage and better formatting of URLs to keep Docker Compose happy, by @kazukitakamatsu and @cemremengu (#12188, #12072).

⚙️ Refactoring & Other Chores

  • Code refactoring to enhance readability and maintainability like using tiktoken for token calculations (@laipz8200, #12416).
  • Cleanup of unused imports for a leaner codebase. Thanks to @bowenliang123 for lint corrections (#11922).
  • A bundle of localization improvements for international users, meticulously handled by the community, including corrections to error messages and localizations (@HanqingZ, #12292).

⚡ Misc

  • Added cheaper and long context models for Qwen2.5-72B-Instruct, and a variety of speech models from siliconflow, contributed by @senseb (#12415, #12425).
  • Squashing bugs related to document parsing that maintained your data format integrity, addressed by @Hisir0909 (#12112).

Get ready to dive into these enhancements and see how they can supercharge your workflows and development experience. Happy coding!
