Trillium Engineering has transitioned its software versioning strategy from a Calendar Versioning model to a standardized Semantic Versioning framework, beginning with software release 3.1.
The 3.1 release supersedes version 26.2 and will begin shipping across all commercial production gimbals in the coming weeks, starting with the HD40 product line. This transition to the Semantic Versioning (X.Y.Z) framework is designed to offer greater visibility, predictability, and scalability as the software expands, giving users a clearer understanding of how updates impact their systems.
Under the X.Y.Z structure, version numbers explicitly define update scope: Major releases (X) deliver architectural shifts or API updates; Minor releases (Y) add backward-compatible capabilities and performance enhancements; and Patch releases (Z) supply bug fixes and stability improvements. Customer-specific software builds will continue to be fully supported with their existing version numbers to maintain stable, locked configurations.
Alongside the versioning update, release 3.1 introduces precise gimbal performance gains through enhanced motion control, enabling smoother movement, improved limit handling, and steadier target hold during aircraft overflight. Tracking functionality features reduced jitter, smoother mode transitions, and cleaner overlays, while EO modes benefit from updated color tuning, white balance, sensor performance, and contrast enhancement for more consistent imagery.
System reliability has been strengthened by addressing unexpected resets, network interruptions, and pipeline crashes alongside safety interlock updates. Additionally, development and production workflows have been streamlined with refined firmware updates, improved configuration-file handling, and updated user-interface behavior to simplify overall system setup and management.
