-  - New data sources: Seafile, RSS, DingTalk AI Sheet.
-  - Added synchronization for file deletions from data sources.
-### Agent
-  - Introduced agent publishing capability
-  - Sandboxed code execution and chart generation
-  - New template: Data Analysis Agent
-### Memory
-  - User-level memory storage and retrieval.
-### Language

+### New features
+
+- Agent
+  - Introduces seven prebuilt ingestion pipeline templates.
+  - Agent apps can be published.
+  - Supports sandbox code execution and chart generation.
+  - Adds a beginner's data analytics Agent template.
+- Memory: Supports user-level memory storage and retrieval.
+- New UI language: Arabic (implemented a Right-to-Left layout), Bulgarian, and Turkish.
+- Ecosystem integration: RAGFlow datasets are accessible via OpenClaw.
+
+### Improvements
+
+- Optimizes Docx parsing by supporting image lazy-loading, reducing memory footprint.
+- Optimizes Chat, Agent, and Search embedded dialog pages for mobile compatibility.
+- Underlying system & infrastructure optimization:
+  - Bumps RAGFlow's document engine, Elasticsearch to 9.x.
+  - Switches the default object storage container to `pgsty/minio` due to the deprecation of the official MinIO images.
+  - Adds database migration scripts; see [this readme](https://github.com/infiniflow/ragflow/tree/74b44e1aa3ecd6687b3aa4ef731d0187720c3cb5/tools/scripts) for further details.
 
 ### Model support
 
-  - MiniMax-M2.7 series models
-  - Perplexity embedding model: pplx-embed
-  - Tongyi rerank model

-### Improvements
-- Improved DOCX parsing strategy with lazy-load support for images, reducing memory consumption.
-- DocEngine: supports upgrade to Elasticsearch 9.x.
-- Embedded chat pages in Chat / Agent / Search are now compatible with mobile devices.
-- Due to MinIO’s official image no longer being maintained, the default object storage container has been changed to pgsty/minio.
-- Database Upgrade: added database upgrade scripts. See documentation: https://github.com/infiniflow/ragflow/blob/main/tools/scripts/README.md.
