# Introduction {#introduction}

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

The extension provides a form finisher for the [TYPO3 Form Framework](https://docs.typo3.org/c/typo3/cms-form/14.3/en-us/Index.html) for rate limiting when sending a form. This way a submission
can be restricted to, for example:

-   one IP address over all forms using this finisher
-   a combination of IP address and specific form
-   a combination of a specific form and an email address

If the limit is exceeded, a customizable error is displayed.

## Release management {#release-management}

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.
