+## 4.0.0
+    - This version is a complete rewrite over version 3.0.0 See #103
+    - This Plugin now uses the V2 version of the SDK, this make sure we receive the latest updates and changes.
+    - We now uses S3's `upload_file` instead of reading chunks, this method is more efficient and will uses the multipart with threads if the files is too big.
+    - You can now use the `fieldref` syntax in the prefix to dynamically changes the target with the events it receives.
+    - The Upload queue is now a bounded list, this options is necessary to allow back pressure to be communicated back to the pipeline but its configurable by the user.
+    - If the queue is full the plugin will start the upload in the current thread.
+    - The plugin now threadsafe and support the concurrency model `shared`
+    - The rotation strategy can be selected, the recommended is `size_and_time` that will check for both the configured limits (`size` and `time` are also available)
+    - The `restore` option will now use a separate threadpool with an unbounded queue
+    - The `restore` option will not block the launch of logstash and will uses less resources than the real time path
+    - The plugin now uses `multi_receive_encode`, this will optimize the writes to the files
+    - rotate operation are now batched to reduce the number of IO calls.
+    - Empty file will not be uploaded by any rotation rotation strategy
+    - We now use Concurrent-Ruby for the implementation of the java executor
+    - If you have finer grain permission on prefixes or want faster boot, you can disable the credentials check with `validate_credentials_on_root_bucket`
+    - The credentials check will no longer fails if we can't delete the file
+    - We now have a full suite of integration test for all the defined rotation
