# Important: New required dependency `fgtclb/environment-state-manager` {#important-ace-254-academic-persons}

## Description {#description}

EXT:academic_persons now depends on the standalone extension
[`fgtclb/environment-state-manager`](https://packagist.org/packages/fgtclb/environment-state-manager) and declares it in both
`composer.json` (`"fgtclb/environment-state-manager": "^1.0"`) and
`ext_emconf.php` (`'environment_state_manager' => '1.0.0-1.99.99'`).

The extension was switched from the internal, now deprecated
`\FGTCLB\AcademicBase\Environment` subsystem to the extracted
[`fgtclb/environment-state-manager`](https://packagist.org/packages/fgtclb/environment-state-manager) extension (namespace
`\FGTCLB\EnvironmentStateManager`), which it uses in its profile command
services. The dependency is therefore required at runtime.

## Impact {#impact}

Composer-managed installations pull [`fgtclb/environment-state-manager`](https://packagist.org/packages/fgtclb/environment-state-manager)
in automatically when EXT:academic_persons is updated to 2.4. No action is
required.

Classic, non-Composer installations (TER, extension manager) must install the
extension `environment_state_manager` in addition to EXT:academic_persons.
Otherwise the extension cannot be activated.

## Affected Installations {#affected-installations}

Only non-Composer installations updating EXT:academic_persons to 2.4 need to
install the additional extension manually. Composer-managed installations are
unaffected.
