Nov 1, 2025Month: 2025-11. Summary: Delivered two core features for pantavisor/meta-pantavisor to strengthen build stability and base image alignment. Key features delivered: 1) PVR Recipe Update to Version 046: updated the pvr recipe to 046, renamed the recipe file, and updated SHA256 checksums to lock to the latest package, ensuring the build uses the correct pvr release and reducing risk of outdated components. 2) Pantavisor Distro Version Bump: raised DISTRO_VERSION from 019 to 021 by updating config files (panta-distro-app.conf, panta-distro-bsp.conf, panta-distro.conf), aligning with updated base images and configurations for improved compatibility and reproducibility.

Apr 1, 2025April 2025 monthly summary for pantavisor/meta-pantavisor. Key deliveries focused on improving build reliability and release traceability. Implemented a conditional installation of /etc/resolv.conf during Pantavisor builds to avoid conflicts with user-provided configurations, preventing related package conflicts. Introduced dynamic, git-based versioning for multiple recipes using gitpkgv to produce meaningful versions across dropbear, libthttp, lxc-pv, and pantavisor. These changes enhance reproducibility, reduce risk in customer environments, and streamline release processes. Demonstrated Yocto/BitBake patching, patch integration, and packaging governance using git-based versions.
