Added

🛠️ Global Tool Servers Configuration: Admins can now centrally configure global external tool servers from Admin Settings > Tools, allowing seamless sharing of tool integrations across all users without manual setup per user.
🔐 Direct Tool Usage Permission for Users: Introduced a new user-level permission toggle that grants non-admin users access to direct external tools, empowering broader team collaboration while maintaining control.
🧠 Mistral OCR Content Extraction Support: Added native support for Mistral OCR as a high-accuracy document loader, drastically improving text extraction from scanned documents in RAG workflows.
🖼️ Tools Indicator UI Redesign: Enhanced message input now smartly displays both built-in and external tools via a unified dropdown, making it simpler and more intuitive to activate tools during conversations.
📄 RAG Prompt Improved and More Coherent: Default RAG system prompt has been revised to be more clear and citation-focused—admins can leave the template field empty to use this new gold-standard prompt.
🧰 Performance & Developer Improvements: Major internal restructuring of several tool-related components, simplifying styling and merging external/internal handling logic, resulting in better maintainability and performance.
🌍 Improved Translations: Updated translations for Tibetan, Polish, Chinese (Simplified & Traditional), Arabic, Russian, Ukrainian, Dutch, Finnish, and French to improve clarity and consistency across the interface.

Fixed

🔑 External Tool Server API Key Bug Resolved: Fixed a critical issue where authentication headers were not being sent when calling tools from external OpenAPI tool servers, ensuring full security and smooth tool operations.
🚫 Conditional Export Button Visibility: UI now gracefully hides export buttons when there's nothing to export in models, prompts, tools, or functions, improving visual clarity and reducing confusion.
🧪 Hybrid Search Failure Recovery: Resolved edge case in parallel hybrid search where empty or unindexed collections caused backend crashes—these are now cleanly skipped to ensure system stability.
📂 Admin Folder Deletion Fix: Addressed an issue where folders created in the admin workspace couldn't be deleted, restoring full organizational flexibility for admins.
🔐 Improved Generic Error Feedback on Login: Authentication errors now show simplified, non-revealing messages for privacy and improved UX, especially with federated logins.
📝 Tool Message with Images Improved: Enhanced how tool-generated messages with image outputs are shown in chat, making them more readable and consistent with the overall UI design.
⚙️ Auto-Exclusion for Broken RAG Collections: Auto-skips document collections that fail to fetch data or return "None", preventing silent errors and streamlining retrieval workflows.
📝 Docling Text File Handling Fix: Fixed file parsing inconsistency that broke docling-based RAG functionality for certain plain text files, ensuring wider file compatibility.
