Semantic Versioning (SemVer)

Introduction to Semantic Versioning

Hi there! Welcome to our session on Semantic Versioning (SemVer). Today, we're going to delve into the world of versioning and understand why it's crucial for managing software releases.

Why Semantic Versioning?

SemVer is a set of rules that helps developers and users understand the nature and purpose of software releases. It provides a consistent and clear way of communicating changes in a software product.

SemVer Components

SemVer consists of three main components:

  • Major Version: Significant changes, introducing new features or breaking changes.
  • Minor Version: New features or enhancements, but no breaking changes.
  • Patch Version: Bug fixes or minor improvements.

Pre-Release Version

SemVer also includes pre-release versions to indicate that software is still under development. These versions have a suffix like -alpha, -beta, or -rc.

Build Metadata

Additionally, SemVer allows for build metadata to be included. This metadata is typically used for internal purposes like build numbers or timestamps.

Version Comparison

To compare SemVer versions, use the following rules:

  • Higher major versions are always considered newer.
  • Higher minor versions within the same major version are newer.
  • Higher patch versions within the same minor version are newer.
  • Pre-release versions are always considered less stable than official releases.

Semantic Versioning in Action

Let's take an example:
1.0.0: Initial release.
1.1.0: New feature added.
1.1.1: Bug fix released.
1.2.0-alpha: Pre-release version with new features being tested.

Importance of Semantic Versioning

Semantic Versioning is crucial because it:

  • Provides clear and concise information about software changes.
  • Ensures backward compatibility by avoiding breaking changes in minor and patch releases.
  • Facilitates version dependency management, allowing developers to specify the required or compatible versions of other software.
