# Feature: Initial release {#feature-initial-release}

## Description {#description}

Initial release of the `fgtclb/environment-state-manager` extension. The
environment builder and state manager were extracted from
`fgtclb/academic-base` into this dedicated, reusable extension.

The extension provides:

-   `EnvironmentBuilderFactory` returning a TYPO3 core version compatible
    environment builder for TYPO3 v12 and v13. A `FrontendEnvironmentBuilder`
    and a `BackendEnvironmentBuilder` are shipped (see
    [Feature: Backend environment builder](https://docs.typo3.org/permalink/fgtclb/environment-state-manager:feature-backend-environment-builder@main)).
-   `StateManager` to bootstrap, apply, back up and restore an environment
    state.
-   `StateApplyEvent` and `StateBackupEvent` PSR-14 events.

The classes are provided under the `FGTCLBEnvironmentStateManager`
namespace. See the [Developer Corner](https://docs.typo3.org/permalink/fgtclb/environment-state-manager:developer@main) for usage examples.
