# Important: #89764 - Incompatible environment related dependency injection services have been removed {#important-89764}

See [forge#89764](https://forge.typo3.org/issues/89764)

## Description {#description}

TYPO3 added support for Symfony 5.0 `symfony/dependency-injection:5` and
therefore had to drop non-object services.

Affected dependency injection services are the following boolean services:

-   env.is_unix
-   env.is_windows
-   env.is_cli
-   env.is_composer_mode

The services variables can be substituted by using dynamic Symfony
environment parameters:

-   "%env(TYPO3:isUnix)%"
-   "%env(TYPO3:isWindows)%"
-   "%env(TYPO3:isCli)%"
-   "%env(TYPO3:isComposerMode)%"
