## 2.1.3
  - Fix spec early termination by removing an explicit return from a block

## 2.1.2
  - Depend on logstash-core-plugin-api instead of logstash-core, removing the need to mass update plugins on major releases of logstash

## 2.1.1
  - New dependency requirements for logstash-core for the 5.0 release

## 2.1.0
 - Add caches for failed and successful lookups
 - Lower default timeout value

 - Plugins were updated to follow the new shutdown semantic, this mainly allows Logstash to instruct input plugins to terminate gracefully,
   instead of using Thread.raise on the plugins' threads. Ref: https://github.com/elastic/logstash/pull/3895
 - Dependency on logstash-core update to 2.0
