Understanding Semantic Versioning (SemVer) and Its Workflow
Semantic Versioning (SemVer) is a structured software versioning scheme that uses a three-part major.minor.patch format to clearly convey the impact of changes, guiding developers through initial development, stable releases, subsequent updates, and special pre‑release or build metadata versions.
Semantic Versioning (SemVer) is a versioning scheme that conveys the meaning of changes using a three-part version number: major.minor.patch.
Major : incremented for incompatible API changes.
Minor : incremented for backward‑compatible feature additions.
Patch : incremented for backward‑compatible bug fixes.
The article illustrates a typical workflow, starting from an initial development phase (0.1.0) with incremental changes (0.1.1, 0.2.0, …), reaching the first stable release 1.0.0, and then showing subsequent patches, minor updates, and major releases up to 2.0.0.
Initial Development Phase
Version 0.1.0 is created, followed by incremental changes and bug fixes such as 0.1.1, 0.2.0, 0.2.1, 0.3.0.
First Stable Release
The stable version 1.0.0 is released.
Subsequent Changes
Patch releases 1.0.1, 1.0.2, 1.0.3; minor release 1.1.0 adding a backward‑compatible feature; further minor releases 1.2.0 with additional features and patches 1.2.1, 1.2.2; a major release 2.0.0 introducing incompatible changes.
Special and Pre‑Release Versions
Pre‑release identifiers are appended with hyphens (e.g., 1.0.0-alpha , 1.0.0-beta , 1.0.0-rc.1 ). Build metadata is added with a plus sign (e.g., 1.0.0+20130313144700 ).
By following SemVer, developers can manage dependencies and communicate change impact clearly, ensuring predictable and stable software evolution.
