12/3/2023 0 Comments Git tag semantic versioning![]() ![]() It was built to solve the versioning story for a single package, but also how a single package interoperates with dependencies. Semantic Versioning, or SemVer for short, is likely the most popular versioning scheme in software today. First, let’s talk about Semantic Versioning. Throughout this article, we’ll talk about the various pieces that I believe provide a holistic picture of the software that is packaged into a release and running on a device. If a project chooses to use just a Git SHA, or a build timestamp, or a random ASCII name, then many or all of the above benefits that versions typically provide are lost. Tell users when major changes took place (e.g.Reference a specific build of the software.Reference a specific revision of the software.Encode compatibility information, breaking changes, and upgrade/downgrade restrictions.Providing an ordering to versions (e.g.They serve other purposes! Such purposes include, but are not limited to: Versions don’t exist just to differentiate one release from another. This post builds upon many of our previous posts and brings all the relevant information together under one post. In this article, we are going to talk through all the various pieces of metadata to be included in your firmware binaries, debug symbols, and build artifacts so that developers and machines can quickly and easily know exactly which build is which and how to fetch associated files for the debug, test, and release pipeline. With all of this in place, both machines and developers can quickly figure out exactly which release is running on a given device, what the source is, where it came from, and how to rebuild it if necessary. I’m not here to say they are wrong, but I’d like to discuss what they might be missing out on.Īlong with a typical release version, it is useful to include extra metadata, such as the Git revision, GNU Build ID, build timestamp, and other related items. We don’t live in this ideal world unfortunately and many projects choose to deviate from versioning standards. ![]() There should only be a couple of right ways to do versioning, and each project should pick one of the agreed-upon methods (SemVer 1, CalVer 2, etc.) that makes the most sense to the project. Release versioning might seem like a boring topic. ![]()
