 ### Changes
+* [#43](https://github.com/cleverage/archive-process-bundle/issues/43) Composer: require PHP `^8.2` instead of `>=8.2` (PHP 9 is no longer accepted before being tested), remove the authorization of the `symfony/flex` plugin, which is not required (the CI installs it globally), as [cleverage/process-bundle#319](https://github.com/cleverage/process-bundle/issues/319).
 * [#38](https://github.com/cleverage/archive-process-bundle/issues/38) Define the public API (Symfony BC promise, as [cleverage/process-bundle#279](https://github.com/cleverage/process-bundle/issues/279)): `ZipTask`, `UnzipTask` and `CleverAgeArchiveProcessBundle` are marked `@final since 2.3`, they will be `final` in 3.0: extending them triggers a deprecation with the Symfony `DebugClassLoader`. `CleverAgeArchiveProcessExtension` is marked `@internal`.
 * [#37](https://github.com/cleverage/archive-process-bundle/issues/37) `CleverAgeArchiveProcessExtension::findServices()` loads the service definition files with a glob pattern instead of a `Finder` (same files, as [cleverage/process-bundle#271](https://github.com/cleverage/process-bundle/issues/271)), `symfony/finder` is no longer required. Add tests.
 * [#35](https://github.com/cleverage/archive-process-bundle/issues/35) Require `symfony/polyfill-php83`, `symfony/polyfill-php84` and `symfony/polyfill-php85` ([cleverage/process-bundle#299](https://github.com/cleverage/process-bundle/issues/299)): the functions of PHP 8.3 to 8.5 can be used while supporting PHP 8.2. Rector targets PHP 8.2 (`withPhpVersion()`, `withPhpSets()` read from `composer.json`) and applies the rules using a newer function when its polyfill is required (no change in the current code).
