# Global meta information about TYPO3

## General information

The PHP class `\TYPO3\CMS\Core\Information\Typo3Information` provides an API for general
information, links and copyright information about TYPO3.

The following methods are available:

-   `getCopyrightYear()` will return a string with the current copyright years (for example "1998-2020")
-   `getHtmlGeneratorTagContent()` will return the backend meta generator tag with copyright information
-   `getInlineHeaderComment()` will return the TYPO3 header comment rendered in all frontend requests ("This website is powered by TYPO3...")
-   `getCopyrightNotice()` will return the TYPO3 copyright notice

> [!WARNING]
> DO NOT prevent the copyright notice from being shown in ANY WAY.
> According to the GPL license an interactive application must show such a notice on start-up
> ('If the program is interactive, make it output a short notice... ' )
> Therefore preventing this notice from being properly shown is a violation of the license, regardless of whether
> you remove it or use a stylesheet to obstruct the display.

## Version information

PHP class `\TYPO3\CMS\Core\Information\Typo3Version` provides an API for
accessing information about the currently used TYPO3 version.

-   `getVersion()` will return the full TYPO3 version (for example `10.4.3`)
-   `getBranch()` will return the current branch (for example `10.4`)
-   `getMajorVersion()` will return the major version number (for example `10`)
