v0.26.3

## Summary

Released on July 2, 2026.

### New features

- Data source connector: Introduces Google BigQuery as a data source connector for document ingestion and incremental syncing. [#15871](https://github.com/infiniflow/ragflow/pull/15871)
- MCP: Adds two MCP tools `ragflow_list_datasets` and `ragflow_list_chats` to the RAGFlow MCP server. [#15384](https://github.com/infiniflow/ragflow/pull/15384)
- File ingestion
  - Integrates the layout-aware SoMark OCR parser into the system for extracting and indexing complex document elements like tables and figures. [#16482](https://github.com/infiniflow/ragflow/pull/16482)
  - API: Exposes the [Ingest documents](./references/http_api_reference.md#ingest-documents) endpoint for processing documents using a customized pipeline. [#16395](https://github.com/infiniflow/ragflow/pull/16395)

### Improvements

- Backend: Introduces partial success handling for batch document uploads, ensuring that a single failed file no longer causes the entire batch to be discarded. [#16438](https://github.com/infiniflow/ragflow/pull/16438)
- UI/UX: Refactors the global header to dynamically switch between a full desktop navigation bar and a mobile-friendly side drawer based on available screen space, resolving overlapping issues and significantly improving the mobile user experience. [#15984](https://github.com/infiniflow/ragflow/pull/15984)

### Bug fixes

- After setting up the Ollama provider, the system returned the error: 'Failed to access model(name) using this api key'. [#16519](https://github.com/infiniflow/ragflow/pull/16519)
- Deleting a user/assistant chat message pair mistakenly removed the previous conversation turn's reference due to an index misalignment. [#16436](https://github.com/infiniflow/ragflow/pull/16436)
