On March 3, 2025, we released version 25.03 of our product analytics platform, delivering a focused set of updates that refine how we handle data, improve our user interface, and expand compatibility with cutting-edge technologies. While our major new functionality—Journeys and Content Builder—was already introduced in a separate article (read it here), this release brings additional enhancements worth exploring. Detailed in our full changelog on GitHub, these updates zero in on foundational improvements that make our platform more efficient, intuitive, and versatile. In this post, we’ll dive into four key changes: a streamlined event data model, widespread UI upgrades, support for MongoDB 8 and NodeJS 20, and the exciting addition of SingleStore Kai as a database option.
We’re committed to empowering teams with robust analytics across mobile, web, and desktop applications. With 25.03, we’ve taken significant steps to modernize our infrastructure and elevate the user experience. Let’s explore what’s new.
We’ve transformed how we store event data in 25.03 by consolidating everything into a single MongoDB collection. Previously, our event data was spread across multiple collections, which could complicate queries and increase overhead for high-volume applications. Now, by unifying events into one collection, we’ve simplified our data structure, making it more efficient to process and retrieve analytics.
This shift reduces database complexity and improves query performance, especially for teams tracking large numbers of custom events. Whether you analyze user interactions, campaign outcomes, or feature usage, this streamlined model ensures faster insights without sacrificing flexibility.
Why It Matters: A leaner data model means quicker dashboards and less maintenance for your team. It’s a behind-the-scenes upgrade that delivers real-world speed and simplicity.
Our dashboard got a major facelift in 25.03, with a slew of UI improvements designed to make your analytics experience smoother and more intuitive. We’ve polished numerous elements across the interface—resulting in cleaner layouts, more responsive controls, and enhanced visual clarity. These updates span everything from widget rendering to navigation flows, ensuring that interacting with your data feels effortless.
For example, we’ve refined how dashboards display complex datasets, making it easier to spot trends at a glance. Subtle enhancements to buttons, tooltips, and menus also improve usability and user experience.
Why It Matters: A better UI isn’t just about looks—it’s about productivity. These changes help you focus on insights. A smoother experience means faster decisions and better outcomes.
We’re keeping pace with the latest tech stacks by adding support for MongoDB 8 and NodeJS 20 in 25.03. MongoDB 8, released with performance boosts and new features like enhanced aggregation pipelines, lets us leverage cutting-edge database capabilities for faster analytics processing. Meanwhile, NodeJS 20 brings improved memory management and modern JavaScript features, ensuring our server-side engine runs efficiently on the latest runtime.
To make upgrading seamless, we’ve prepared a detailed upgrade guide, walking you through the steps to transition your deployment. Whether you’re running on-premises or in the cloud, these updates future-proof your setup.
Why It Matters: Staying current with MongoDB 8 and NodeJS 20 means better performance and longevity for your analytics platform. It’s our way of ensuring you’re always on the leading edge.
Perhaps the most exciting addition in 25.03 is our new support for SingleStore Kai as an optional database backend. Built for high-speed analytics and real-time workloads, SingleStore Kai integrates seamlessly with MongoDB APIs, offering a drop-in alternative for teams seeking blazing-fast query performance. This option lets us tap into SingleStore’s hybrid transactional-analytical processing (HTAP) capabilities, which are ideal for applications demanding instant insights from massive datasets.
By adding SingleStore Kai, we’re giving you more flexibility in how you deploy our platform. Whether you stick with MongoDB or switch to SingleStore Kai, you’ll benefit from a database tailored to your performance needs.
Why It Matters: Choice is power. SingleStore Kai support opens the door to ultra-fast analytics, making it a game-changer for data-intensive use cases.
Our 25.03 release refines the core of what we do—delivering fast, reliable, and intuitive analytics. The single-collection event model streamlines your data pipeline, the UI improvements make insights more accessible, and support for MongoDB 8, NodeJS 20, and SingleStore Kai ensures our platform thrives in modern environments. Together, these updates enhance efficiency and adaptability for teams of all sizes.
