Neon OS Releases

Neon OS releases can be primarily differentiated by a core version and an image version, where core refers to the repository providing the primary functionality (i.e. neon-core or neon-nodes) and image refers to code from the neon_debos repository. A particular OS release is identified by a build version string based on the time at which the release was compiled.

Identifying Updates

Updates are identified as OS releases with the same core and a newer build version.

A build version is marked as a beta if either the core or the image ref used is a beta (these will always be the same ref in automated builds). A device on a beta update track will only update to a newer beta version; a device on a stable update track will only update to a newer stable version. If a device changes tracks, it will update to a NEWER release on the new track, but it will not install an older version by default.

Note that in practice, any stable update will have first been released to the beta track.

Version Management

Released images are identified in GitHub releases in this repository. The yaml index files may also be used to view release history per-image. Each yaml index entry has a version key that corresponds to a unique build; two builds may have the same core and image versions but different build versions based on when they were created.

Versioning Scheme

Releases will follow CalVer, so a release version may be 24.02.14 or 24.02.14b1. Note that the GitHub beta tags will not match the associated images' versions for beta versions since each release may relate to a different core.

i.e. Neon OS tag 24.02.27.b1 may contain debian-neon-image-24.02.27b1 and Neon OS tag 24.02.27.b2 may contain debian-node-image-24.02.27b4.

Glossary

• core: the module/repository providing the primary functionality
• image: the framework/repository building the OS image (neon-debos)
• build id: recipe-platform string identifier (i.e. debain-neon-image-rpi4)
• build version: the version identifier for a specific release image
• release: a versioned release in the Neon OS repository.
