Trillium Engineering has transitioned its software versioning strategy from a Calendar Versioning (CalVer) model to a standardized Semantic Versioning (X.Y.Z) framework beginning with software release 3.1.
The move provides a clearer way to communicate the scope and impact of software updates, making it easier for users to understand system changes and potential operational effects. As part of this transition, the current software version 26.2 is superseded by the 3.1 release. Over the upcoming weeks, all commercial production gimbals will be shipped with the 3.1 release, starting with the HD40 product line.
Under the new X.Y.Z structure, Major Releases (X) introduce significant architectural changes or compatibility updates, such as API updates or architectural shifts. Minor Releases (Y) deliver new capabilities, performance enhancements, and feature additions while maintaining full backward compatibility.
As Trillium’s software continues to expand, this operational pivot is said to establish a more scalable and predictable process. Trillium believes it provides customers with greater visibility into software updates and clarifies expectations for each release cycle.
Customer-specific software builds will continue to be fully supported and will retain their existing version numbers. The structural change does not affect the company’s ability to maintain stable, locked configurations for customer-specific releases. For questions regarding software compatibility, release planning, or upgrade paths, users can contact their Trillium representative or the Trillium Support team.
