Summary

Released on July 7, 2026.

New features

• NLP/Tokenization: Adds a language-aware Snowball stemmer supporting 16 languages, integrates the dataset language parameter across the tokenization pipeline, and adds Dutch to the frontend. #14140

Bug fixes

• The system crashed with a ValueError when parsing LM-Studio model names containing an '@' symbol. #16467
• The MCP server crashed because the list_chats function expected a list from the /chats API but received a paginated dictionary instead. #16639
• The Docling parser silently dropped mathematical formulas from documents instead of extracting them. #16645
• The system failed to persist inline edits made to metadata values to the backend. #16655
• The system removed existing links when bulk-linking files to datasets. #16587
• The filter failed to use Chinese. #16673
• The system failed to enforce that tag weights must be greater than zero. #16657
• The layout of the agent prompt dropdown menu rendered incorrectly. #16653
• The Laws chunker incorrectly classified dotted-number cross-references as headings. #16626
• The system failed to prevent users from saving duplicate MCP server names during the editing process. #16588
• The system allowed users to export an empty MCP server selection. #16589
