Software versioning is the process of assigning either unique version names or unique version numbers to unique states of computer software. Here's what we use in our company: Major.Minor.Patch version.Build Number. The Major change involves a full release cycle, including marketing involvement etc. This number is controled by forces outside of R&D (for example, in. Windows versions can be identified using their Major version, their Minor version and. How to determine your Windows Server 2008 version. Linux/Python Compatible Semantic Versioning 3. This is a fork of Semantic Versioning 2. The specific changes have to do. Linux distribution packaging and Python. Inspiration for the format of the pre- release and build labels. Python’s PEP4. 40. Changes vs Sem. Ver 2. The basic intent is that MAJOR versions are incompatible. This section details how we will build the code to meet the above requirements and guidelines. From Second Life Wiki. The four places in the w.x.y.z version string correspond to Major.Minor.Patch.Revision. The final place in the viewer version contains a Build number unique to each. What do the numbers in a version typically represent. Semantic Versioning is a. A semantic version number always follows this pattern MAJOR.MINOR.PATCH. MAJOR version when you. Seeing the version number they now. These are extremely useful when. CI and CD systems when . Pre- release versions are now separated by . If the dependency specifications are too. If dependencies are specified too loosely, you will inevitably. Dependency hell is where you are. As a solution to this problem, I propose a simple set of rules and. These rules are based on but not necessarily limited to. For this system to work, you first need to declare. API. This may consist of documentation or be enforced by the. Regardless, it is important that this API be clear and. Once you identify your public API, you communicate changes to. Consider a version. X. Y. Z (Major. Minor. Patch). Bug fixes not affecting the API. API additions/changes. API changes. increment the major version. I call this system “Semantic Versioning.” Under this scheme, version. Semantic Versioning Specification (Sem. Ver). This. API could be declared in the code itself or exist strictly in. However it is done, it should be precise and. A normal version number MUST take the form X. Y. Z where X, Y, and Z. MUST NOT contain leading zeroes. X is. the major version, Y is the minor version, and Z is the patch. Each element MUST increase numerically. For instance: 1. 9. Once a versioned package has been released, the contents of that. MUST NOT be modified. Any modifications MUST be released as. Major version zero (0. Anything may. change at any time. The public API should not be considered stable. Version 1. 0. 0 defines the public API. The way in which the version. API and how it changes. Patch version Z (x. Z . A bug fix is defined. Minor version Y (x. Y. z . It MAY be incremented if substantial new functionality. It MAY. include patch level changes. Patch version MUST be reset to 0 when. Major version X (X. It. MAY also include minor and patch level changes. Patch and minor. version MUST be reset to 0 when major version is incremented. A pre- release version MAY be denoted by appending a dot. The identifier MUST NOT be empty. A pre- release version indicates that. Examples: 1. 0. 0. A development version MAY be denoted by appending a dot separated. The identifier MUST NOT be empty. Development versions. A development version is a completely unsupported and conveys no. API promises when related to other versions. They are more useful as. Dev versions. are not public artifacts and should never be placed in public. Examples. 1. 0. 0. MAY be denoted by appending a dot separated. The sha MUST NOT be empty. Thus. two versions that differ only in the git version, have the same. Example: 1. 0. 0. Build metadata MAY be denoted by appending a plus sign and a series. Identifiers MUST comprise only ASCII. Identifiers MUST NOT be empty. Build. metadata MUST be ignored when determining version precedence. Thus. two versions that differ only in the build metadata, have the same. Examples: 1. 0. 0. Precedence refers to how versions are compared to each other when. Precedence MUST be calculated by separating the version. Build metadata does not figure into precedence). Precedence. is determined by the first difference when comparing each of these. Major, minor, and patch. Example: 1. 0. 0 < 2. When major, minor, and patch are equal, a pre- release. Example. 1. 0. 0. When major, minor, patch and pre- release are equal, a. Example: 1. 0. 0. Precedence for two pre- release. MUST be determined. If the alpha portion does not match, the sort order. Example: 1. 0. 0. If all other components are not equal, predence is determined. Why Use Semantic Versioning? In fact, you probably do. The problem is that “close” isn’t good. Without compliance to some sort of formal specification, version. By giving a. name and clear definition to the above ideas, it becomes easy to. Once these. intentions are clear, flexible (but not too flexible) dependency. A simple example will demonstrate how Semantic Versioning can make. Consider a library called. Firetruck.” It requires a Semantically Versioned package named. Ladder.” At the time that Firetruck is created, Ladder is at version. Since Firetruck uses some functionality that was first introduced. Ladder dependency as greater than. Now, when Ladder version 3. As a responsible developer you will, of course, want to verify that any. The real world is a messy. What you. can do is let Semantic Versioning provide you with a sane way to release. If all of this sounds desirable, all you need to do to start using. Semantic Versioning is to declare that you are doing so and then follow. Link to this website from your README so others know the. FAQ. If you have a stable API on which users have come to depend. If you’re worrying a lot about backwards. Doesn’t this discourage rapid development and fast iteration? If you’re changing. API every day you should either still be in version 0. If even the tiniest backwards incompatible changes to the public API require a major version bump, won’t I end up at version 4. The cost that must be incurred to upgrade. Having to bump major versions to release. Documenting the entire public API is too much work! Managing software. In the long run, Semantic Versioning, and the. API can keep everyone and everything. What do I do if I accidentally release a backwards incompatible change as a minor version? Even under this. circumstance, it is unacceptable to modify versioned releases. If it’s. appropriate, document the offending version and inform your users of the. What should I do if I update my own dependencies without changing the public API? Software that explicitly depends on the same dependencies as your. Determining whether the change is a patch. I. would usually expect additional code for the latter instance, in which. What if I inadvertently alter the public API in a way that is not compliant with the version number change (i. If you have a huge audience that will be. API intended, then it may be best to perform a major version release. If these changes are important to your users. How should I handle deprecating functionality? When you. deprecate part of your public API, you should do two things: (1) update. Before you completely. API. Does Sem. Ver have a size limit on the version string? A 2. 55 character version string is probably. Also, specific systems may impose their own.
