Package updates across multiple architectures and long-term release branches complicate pipeline testing. Source-level tests usually pass during a package upgrade, missing Application Binary Interface (ABI) changes that later break downstream images and containers at runtime.

This talk introduces an extension to meta-binary-audit [1] that adds automated binary analysis to release CI pipelines for Yocto environments. Integrating libabigail into the pipeline reports exactly what changed in the binary interface before code is released.

The session details the CI architecture, parallel binary audits across multiple architectures, and how to track symbol-level ABI changes during LTS uplifts, using the migration from Scarthgap to Wrynose as an example. Attendees will leave with practical methods to analyze these interface changes, evaluate compatibility across releases, and prevent broken downstream images.
