The AGL platform hits 20 major releases with Terrific Trout, the newest version of the Automotive Grade Linux (AGL) Unified Code Base (UCB). The UCB 20.0 release continues our mission to provide an open, production-ready platform that accelerates software innovation for connected and software defined vehicles.
The Terrific Trout release brings a range of updates and improvements across the platform. Here are some of the highlights:
Updated Yocto Base
Terrific Trout is built on Yocto Project Scarthgap 5.0.10, bringing improved stability, security updates, and compatibility with the latest development tools. AGL remains committed to following Yocto Project LTS updates and will provide updates to Terrific Trout as new Scarthgap versions are released. In addition, we continue to support Yocto Project updates based on the Yocto Project Kirkstone LTS version (4.0.x) with updates to Quirky Quillback as Kirkstone releases are made.
Enhanced Graphics
