February 2026
This release brings a major set of user interface changes to PeCan, including redesigned navigation, integrated help guides, and updated keyboard controls. Watch the video below or read on for a full breakdown of what's changing and why.
New Features
- Redesigned Navigation. New left-side navigation panel for easy navigation between data facets and access to the Diagnosis Search. This redesign lays the groundwork for a new cohort building feature that we expect to land later this year—stay tuned!
- Help Guides. Navigation to our PeCan Help Guide documentation is now accessible on the new left-side navigation panel. We intend to continue contributing heavily to PeCan's help guides in the months and years to come.
- Keyboard Controls. Updated keyboard controls to quickly access PeCan's Diagnosis Search. Our goal is to continue sharpening the experience of using PeCan seamlessly for frequent visitors.
Improvements
- Accompanying all of the user interface changes, we've updated the position of the Diagnosis Search on the PeCan Homepage to better fit in with the new position of the navbar.
We welcome feedback on these changes! Anyone is welcome to reach out to us at support@stjude.cloud or via the chat bubble integrated on the site.
