 ### Changes
+* [#55](https://github.com/cleverage/cache-process-bundle/issues/55) `CleverAgeCacheProcessExtension::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.
 * [#53](https://github.com/cleverage/cache-process-bundle/issues/53) AdapterRegistry: the adapters are loaded lazily from a service locator indexed by code: an adapter is only instantiated when a task uses it (an error in an adapter that a process does not use no longer makes it fail). The code is given by the new `code` attribute of the `cleverage.cache.adapter` tag, or by the new `#[AsCacheAdapter(code: '...')]` attribute (autoconfiguration); it must be the one returned by `getCode()`. Duplicate or empty codes fail the container compilation. An adapter tagged without `code` is still registered eagerly, with `AdapterRegistry::addAdapter()`, which is deprecated (the `code` will be required in 3.0). New optional `AdapterRegistry` constructor argument (the locator), new `hasAdapter()` and `getAdapters()` methods. Require `symfony/service-contracts`. Update documentation, add tests.
 * [#51](https://github.com/cleverage/cache-process-bundle/issues/51) Use the PHP 8.3 to 8.5 functions through the Symfony polyfills ([cleverage/process-bundle#299](https://github.com/cleverage/process-bundle/issues/299)): require `symfony/polyfill-php83`, `symfony/polyfill-php84` and `symfony/polyfill-php85`. Rector is configured with the minimum supported PHP version (`withPhpVersion(PhpVersion::PHP_82)`, it used PHP 8.5 features) and `withPhpSets()` without explicit version, which applies the rules using a newer function when its polyfill is required (no change on the current code). Document it in `CONTRIBUTING.md`.
 * [#49](https://github.com/cleverage/cache-process-bundle/issues/49) Add a `CleverAge\CacheProcessBundle\Registry\AdapterRegistry` alias of the `cleverage_cache_process.registry.adapter` service: the registry can be autowired, e.g. in a custom cache task extending `AbstractCacheTask`. Update documentation, add tests.
