+# Upgrade to 1.0.0
+
+While version 1.0.0 is largely backwards compatible from earlier versions in every 
+day usage, some parts require a different boostrapping.
+
+## Relocated Adapters
+
+In order to have better dependency management, and to remove some of the
+version contstraints, some of the adapters have been moved out of the main
+repository. These adapters are:
+
+* [AwsS3: AWS SDK V2 Adapter](/adapter/aws-s3-v2/)
+* [AwsS3V3: AWS SDK V3 Adapter](/adapter/aws-s3-v3/)
+* [Dropbox](/adapter/dropbox/)
+* [Rackspace](/adapter/rackspace/)
+* [GridFS](/adapter/gridfs/)
+* [Sftp](/adapter/sftp/)
+* [WebDAV](/adapter/webdav/)
+* [ZipArchive](/adapter/zip-archive/)
+
+##  Caching
+
+Caching has been removed from the main Filesystem class and is now implemented
+as an adapter decorator.
+
+### Version 0.x
+
+~~~ php
+$filesystem = new Filesystem($adapter, $cacheAdapter);
+~~~
+
+### Version 1.0.0
+
+Install the required adapter decorator:
+
+~~~ bash
+composer require league/flysystem-cached-adapter
+~~~
+
+And convert the bootstrapping to:
+
+~~~ php
+use League\Flysystem\Adapter\Local;
+use League\Flysystem\Cached\CachedAdapter;
+
+$decoratedAdapter = new CachedAdapter($adapter, $cacheAdapter);
+$filesystem = new Filesystem($decoratedAdapter);
+~~~
+
+## Helper Methods
+
+In order to clean up the Filsystem class, some helper functions have been moved to plugins.
+
+* ListWith
+* ListPaths
+* ListFiles
+* GetWithMetadata
+* EmptyDir (new)
+
+
