- 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: elastic/logstash#3895
- Dependency on logstash-core update to 2.0
- Altered tag logic to accept and use multiple tags per match.
- Tag field name has changed - it is now "tags" rather than "tag"
- Updated CHANGELOG
