# Breaking: #72451 - Removed deprecated code from backend functions {#breaking-72451}

See [forge#72451](https://forge.typo3.org/issues/72451)

## Description {#description}

Removed deprecated code from backend functions

The following methods have been removed:

`ClickMenu::wrapColorTableCM`
`ClickMenu::excludeIcon`
`ContextMenuAction::getClass`
`ContextMenuAction::setClass`
`SuggestWizardDefaultReceiver::getIcon`
`BackendUserAuthentication::checkCLIuser`
`PageFunctionsController::printContent`
`InfoModuleController::printContent`

The following display condition option have been removed:

-   Evaluates conditions concerning extensions
-   Evaluates whether the field is a value for the default language.

The property `$OS` has been removed from `BackendUserAuthentication`

The property `$doc` has been removed from `InfoModuleController`

## Impact {#impact}

Using the methods above directly in any third party extension will result in a fatal error.

## Affected Installations {#affected-installations}

Instances which use custom calls to one of the methods above.

## Migration {#migration}

For property `$OS` use the constant TYPO3_OS directly.
