U-Boot Concept Releases
This document tracks all concept releases of U-Boot, including both final releases and release candidates.
About Concept Releases
Concept releases are automated builds of U-Boot that are:
Automatically generated when changes are pushed to the master branch
Published as snap packages for easy installation and testing
Available in two variants: QEMU-based and EFI-based builds

These releases allow developers and users to easily test the latest U-Boot features without building from source.
