## 4.0.1
  - Fixes [#38](https://github.com/logstash-plugins/logstash-output-google_cloud_storage/issues/38) - Plugin doesn't start on logstash 7.1.1 - TypeError

## 4.0.0
  - Move to the Java Google Cloud client library for increased performance and stability.
  - **Breaking** If you use the old PKCS12 authentication keys, you will need to upgrade to
    the new JSON keys. Application Default Credentials will continue to work.

### Configuration Changes

**New Options**

 - `json_key_file` - The JSON IAM service account credentials to use with the plugin.

**Deprecations**

 - `key_password` - No longer used with `json_key_file`
 - `service_account` - No longer used with `json_key_file`

**Obsoletions**

 - `key_path` - Use `json_key_file` or Application Default Credentials (ADC) instead.
   See [the documentation](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-google_cloud_storage.html#plugins-outputs-google_cloud_storage-key_path)
   for help about moving to JSON key files.

## 3.3.0
Added the ability to set `gzip` as `Content-Encoding`.
This saves storage size but still allows uncompressed downloads.

- Fixes [#13](https://github.com/logstash-plugins/logstash-output-google_cloud_storage/issues/13) - Use `gzip` for `Content-Encoding` instead of `Content-Type`

## 3.2.1
  - Refactoring work to add locks to file rotation and writing.
    - Fixes [#2](https://github.com/logstash-plugins/logstash-output-google_cloud_storage/issues/2) - Plugin crashes on file rotation.
    - Fixes [#19](https://github.com/logstash-plugins/logstash-output-google_cloud_storage/issues/19) - Deleted files remain in use by the system eventually filling up disk space.

## 3.2.0
  - Change uploads to use a job pool for better performance
    - Fixes [#22](https://github.com/logstash-plugins/logstash-output-google_cloud_storage/issues/22) - Refactor Job Queue Architecture
    - Fixes [#5](https://github.com/logstash-plugins/logstash-output-google_cloud_storage/issues/5) - Major Performance Issues

  - New dependency requirements for logstash-core for the 5.0 release

## 2.0.0
 - Plugins were updated to follow the new shutdown semantic, this mainly allows Logstash to instruct input plugins to terminate gracefully,
