MindsDB Product Updates- December 2025

Welcome to the December 2025 MindsDB Product Updates—a month packed with refinements designed to make your everyday workflows faster, clearer, and more secure. While many updates this cycle focus on under-the-hood improvements, the impact is easy to feel: more reliable Knowledge Bases, smoother integrations, cleaner SQL operations, and documentation that answers your questions before you even ask them.

This release is all about removing friction. Whether you're building agents, managing large datasets, connecting enterprise systems, or collaborating with your team, the platform is now more predictable, more expressive, and far more resilient. Let’s take a look at what’s new.

Knowledge Bases

We rolled out several quality and security improvements this month. We fixed an issue where reranking=false wasn’t being applied correctly, tightened security by hiding Ollama API keys, and updated ChromaDB to automatically clear its storage when a Knowledge Base is deleted—helping you keep things clean and optimized.

We also improved the platform’s resilience with better detection of unusual text encodings and more reliable handling of uppercase table names, ensuring smoother data processing across the board.

Integrations

Several improvements have been made across integrations to boost performance, security, and flexibility.

Ray has been updated from 2.43.0 to 2.52.0, bringing better performance and important bug fixes for a smoother experience overall.

Our PostgreSQL and tokenizer updates now support more optional parameters and improve tokenization during GUI builds, giving users more control and reliability. We’ve also enhanced both PostgreSQL and MySQL integrations with additional configuration options, making database interactions more flexible than ever.

For Snowflake users, we’ve added key file authentication, offering a more secure and convenient way to connect using key-based verification. We also upgraded NumPy to v2+, unlocking performance improvements and new functionality across the platform.

Finally, we introduced updates to MongoDB Render, improving compatibility and making interactions with this widely used NoSQL database more seamless.

Bug Fixes and Improvements

We shipped a wide range of fixes and refinements this month to make MindsDB more stable, secure, and enjoyable to use.

ChromaDB now handles persistent storage more reliably, ensuring consistent data capture across your databases. We also resolved a Jira integration bug, improving overall stability for teams relying on issue data.

A major fix to hybrid search restores smooth, accurate querying, while an update to the REST query endpoint now supports parameters correctly, making the API far more robust. Additional improvements to the GUI and tokenizer eliminate several small glitches and deliver a cleaner, more responsive interface.

To strengthen security, sensitive information is now hidden in logs, protecting credentials and private data during troubleshooting. We also resolved a loading issue with MindsDB Editor Tabs, removed redundant warnings about unused extras, and expanded the pid file with additional data—plus made it fully configurable for more flexibility.

Lastly, we improved coverage validation for datasource handlers and fixed issues affecting REST parameters and JSON variable handling. These updates collectively result in better performance, more predictable behavior, and smoother workflows across the platform.

SQL Operations

We also delivered several SQL improvements aimed at boosting stability, performance, and developer experience.

We fixed a SQLite threading error that could previously cause interruptions, ensuring smoother and more reliable SQL operations. SQL syntax handling has also been enhanced—users can now use ON with SET, improving clarity and aligning queries more closely with expected standards.

Performance has taken a noticeable leap as well. Big data processing in the MySQL text API is now significantly faster, reducing processing time for large datasets. We also optimized inner join execution, resulting in quicker, more efficient queries without compromising data integrity.

Finally, we resolved an issue with case sensitivity in CTEs, ensuring consistent and predictable query behavior.

These changes collectively make MindsDB’s SQL layer faster, more stable, and more intuitive for all users.

Documentation

Documentation upgrades for December help users get more out of MindsDB with less guesswork.

Updates for versions 25.11.1 and 25.12.0 are now live, including details on new features, fixes, and system defaults. We also added comprehensive guidance for optional PostgreSQL parameters and expanded explanations of platform-wide defaults so users can configure MindsDB more confidently.

SQL endpoint documentation has been fully parameterized, giving developers clearer, more precise examples that better match real-world usage. We also introduced a new section covering database naming conventions, helping teams maintain consistency and avoid common pitfalls.

These improvements aim to make MindsDB easier to adopt, easier to understand, and easier to use at scale.

GUI

The Front-end team made sure that we improved the overall experience in the MindsDB GUI. Tabs have been refactored to prevent broken or malformed content, whether you're working locally or in a remote environment. The tree-view now displays long names more cleanly, making navigation easier. We also updated key dependencies to address security alerts and keep everything safer. In the Respond tab, you can now view both context and SQL sections directly inside the thoughts panel. Finally, we resolved a CORS issue that caused credential validation errors when saving a default model.

Conclusion

December’s updates highlight what we care about most: helping teams ship faster with an AI platform that feels easy, stable, and trustworthy. With improved security, smarter syncing, more flexible integrations, optimized SQL performance, and clearer documentation, MindsDB continues to evolve into a more seamless layer between your data and your AI workflows. You can check out the full Release Notes here.

As we head into 2026, expect even more flexibility in how you build with agents, more automation across data sources, and deeper unification across your analytics and application stack. Every improvement this month brings us closer to a world where intelligent systems can be built—and maintained—as simply as writing SQL.

Thanks for being part of the MindsDB community. Big things are coming next.
