Release [1.4.0](https://github.com/doctrine/DoctrineCacheBundle/miles…

…tone/1)

This release drops support for PHP < 7.1 and marks this bundle as deprecated. With Symfony shipping its own cache component, there is no need to configure caches using this bundle in Symfony anymore.

If you are still using DoctrineCacheBundle to configure caches, please migrate them to symfony/cache. You can tell whether you are using them by checking for a `doctrine_cache` key in your configuration. If you don't see one, you are not actively using this bundle and shouldn't need any changes. If there is a key like that, please migrate to [symfony/cache using FrameworkBundle](https://symfony.com/doc/current/cache.html#configuring-cache-with-frameworkbundle).

If you are using DoctrineBundle, please upgrade to the latest 1.12 release and fix all deprecation messages. This will ensure you are no longer using any DoctrineCacheBundle functionality. Use the `pool` or `service` cache configuration for Doctrine ORM. Once you upgrade to DoctrineBundle 2.0, the DoctrineCacheBundle will be removed unless another package depends on it.

This bundle will continue to receive fixes for bugs and security issues until November 2022, when Symfony 4.4 will reach the first stage of its end-of-life.
