Semver Validator

What Is Semantic Versioning (SemVer)?

Semantic Versioning is a version numbering system used to communicate changes in software releases. A standard version follows the format MAJOR.MINOR.PATCH, such as 1.2.3.

Each number has a specific meaning:

• Major: Increased when incompatible changes are introduced.

• Minor: Increased when new functionality is added in a backward-compatible way.

• Patch: Increased when backward-compatible bug fixes are made.

SemVer also supports pre-release identifiers, such as 2.0.0-beta.1, and build metadata, such as 1.2.3+build.5. These additions help developers identify development releases and build versions.

How to Use the SemVer Validator Online

Use this SemVer checker to verify a version number before including it in a software release, package, or project configuration.

1. Enter a version number: Type a version such as 1.2.3 or 2.0.0-beta.1 into the Semantic Version field.

2. Validate the version: Click Validate to check the entered value against the supported Semantic Versioning rules.

3. Review the result: Check the validation response to determine whether the version follows the expected format.

4. Try a sample: Click Load Sample to load an example version if you want to test the validator.

Semantic Versioning Examples

Here are common version number formats that follow SemVer 2.0.0:

• 1.0.0 — A standard release.

• 1.2.3 — Major version 1, minor version 2, patch version 3.

• 2.0.0-beta.1 — A pre-release version.

• 1.2.3+build.5 — A version with build metadata.

A version such as 1.2 does not follow the standard three-part MAJOR.MINOR.PATCH format.

SemVer Validator Example

Input:

• Semantic Version: 1.2.3

Output:

• Validation Status: Valid SemVer version

• Major: 1

• Minor: 2

• Patch: 3

This illustrates how 1.2.3 fits the standard Semantic Versioning format. The output fields above explain the version; use the actual result displayed by ToolkitCore to confirm the tool’s precise output.
