## 2.2.8

  - Fix #73 Bug in EventTransformCommon#codec_name, use config_name
  - Add regression test for fix to #73

  - Add an optional parameter for `auto_flush`

## 2.2.4

## 2.2.1

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

## 2.2.0

  - The server can now do client side verification by providing a list of certificate authorities and configuring the `ssl_verify_mode`,

    and it will be validated with the know CA.  #8
