V4.9.10

Upgrade Guide

Important: This update rebuilds the full-text index. During the rebuild, full-text search results will be empty. On a 4c16g instance, rebuilding approximately 7 million full-text indexes takes about 25 minutes. For a seamless upgrade, you'll need to handle table synchronization yourself.

New Features

1. Support for setting the systemEnv.hnswMaxScanTuples parameter in PG to increase the total data volume for iterative search.
2. Knowledge base preprocessing now includes a "Chunk Conditions" parameter to control when chunking should be skipped.
3. Knowledge base preprocessing now includes a "Paragraph Priority" mode with configurable maximum paragraph depth. The previous "Length Priority" mode no longer includes embedded paragraph priority logic.
4. Workflow adjusted to single-direction input/output connections, with quick "add next node" support.
5. Lark and Yuque knowledge bases are now available in the Community Edition.
6. Latest Gemini and Claude model presets.

Improvements

1. Increased default timeout for LLM stream calls.
2. Various confirmation dialog UI improvements.
3. Renamed the knowledge base "Table Dataset" to "Backup Import". Also added support for exporting and importing knowledge base indexes.
4. Knowledge base citation limit in workflows: if no related AI nodes exist in the workflow, the interaction mode switches to manual input only, with a limit of 10 million.
5. Mobile voice input now accurately detects whether the device is a phone rather than just a small screen.
6. Optimized context truncation algorithm to always preserve at least one Human message.

Bug Fixes

1. Incorrect score sorting during full-text search across multiple knowledge bases.
2. Stream response potentially capturing incorrect finish_reason values.
3. Tool call mode not saving reasoning output.
4. Knowledge base indexSize parameter not taking effect.
5. Incorrect preview citations and context after 2 levels of workflow nesting.
6. Extra leading space when converting xlsx to Markdown.
7. Base64 images in Markdown files not being extracted and saved during file reading.
