+# Upgrade to 1.4
+
+## Minor BC Break: `Doctrine\Common\Cache\FileCache#$extension` is now `private`.
+
+If you need to override the value of `Doctrine\Common\Cache\FileCache#$extension`, then use the
+second parameter of `Doctrine\Common\Cache\FileCache#__construct()` instead of overriding
+the property in your own implementation.
+
+## Minor BC Break: file based caches paths changed
+
+`Doctrine\Common\Cache\FileCache`, `Doctrine\Common\Cache\PhpFileCache` and
+`Doctrine\Common\Cache\FilesystemCache` are using a different cache paths structure.
+
+If you rely on warmed up caches for deployments, consider that caches generated
+with `doctrine/cache` `<1.4` are not compatible with the new directory structure,
+and will be ignored.
