## What does it do? {#what-does-it-do}

This TYPO3 extension is an add-on to the [schema extension](https://extensions.typo3.org/extension/schema). It provides
additional [schema.org](https://schema.org/) terms related to [auto](https://schema.org/docs/auto.home.html).

For more information about the schema extension have a look into the
[documentation](https://docs.typo3.org/p/brotkrueml/schema/main/en-us/Index.html).

## The schema.org vocabulary {#the-schema-org-vocabulary}

The schema.org vocabulary is evolving, approx. every 2-3 times a year a new
version is [released](https://schema.org/docs/releases.html). The TYPO3 extensions are updated when changes are made
to the according vocabulary. The classes for the type models and view helpers
are generated by the [schema-generator](https://github.com/brotkrueml/schema-generator) library.

## Release management {#release-management-1}

This extension uses [semantic versioning](https://semver.org/) which basically means for you, that

-   Bugfix updates (for example, 1.0.0 => 1.0.1) just includes small bug fixes or
    security relevant stuff without breaking changes.
-   Minor updates (for example, 1.0.0 => 1.1.0) includes new features and smaller
    tasks without breaking changes.
-   Major updates (for example, 1.0.0 => 2.0.0) breaking changes which can be
    refactorings, features or bug fixes.
