v0.26.2

Summary

Released on June 29, 2026.

New features

• Chat channels:
  • Integrates WhatsApp via a QR code scan. #16238
  • Integrates DingTalk via bot API credentials. #16183
  • Integrates WeCom via WebSocket connection. #16175
• File parsing: Adds fallback logic for PP-OCRv6 and similar text recognition models, and integrates image parsing within the PaddleOCR pipeline. #16150

Improvements

• Datasets
  • Adds an edge-case check to the file ingestion logic to safely link empty folders to a dataset. #16296
  • Adds pagination to the get_flatted_meta_by_kbs() method to prevent CRUD failures relating to datasets with more than 10,000 documents. #16095
• Chat channels: Ensures end-user conversation histories persist across restarts but still separate when a channel is bound to a new dialog. #16274

i18n

• Expands i18n coverage and refines translations for the Korean UI. #16203；
• Adds missing French translations for chat channels, username validation, and model editing. #16217

Bug fixes

• File parsing:
  • A ValueError was raised during .docx parsing on 'Heading' styles. #16284
  • Tables in .docx files were silently removed by the laws document parser. #16155
  • Lone Markdown headers were separated from their subsequent sections when a DeepDoc delimiter was set. #16109
  • Markdown tables appeared twice in chunk results, once as a standalone chunk and again within a regular text chunk. #16143
• MCP
  • The MCP server hung indefinitely when encountering empty document pages; the final page of documents was silently dropped due to flawed pagination. #16285
  • The MCP connection and dataset discovery process failed because the server's hardcoded fetch limit exceeded the introduced page_size restriction. #16148
• Dataflow
  • Restores the dataflow rerun endpoint and ensures the ingestion response includes the DSL payload to reliably render the timeline and parser views. #16292
  • Restores dataflow parser defaults and returns the actual SSE payload, ensuring pipeline runs correctly surface message IDs and log updates. #16290
• LLM: Failed to use the new gemini-3.5-flash model via the Google Cloud (Vertex AI) provider using eu or us region endpoint. This is resolved by explicitly multi-region routing requests to the required aiplatform.<region>.rep.googleapis.com domains instead of synthesized <region>-aiplatform.googleapis.com hosts. #15990
• UI/UX: The metadata add modal sent empty values to the backend. #15229
