- Fix some documentation issues
- internal: Upgrade event API dependency to support Logstash 2.4 & 5.x.
- internal: Bump dependency to ftw library to fix compatibility problem.
- Depend on logstash-core-plugin-api instead of logstash-core, removing the need to mass update plugins on major releases of logstash
- New dependency requirements for logstash-core for the 5.0 release
- The "mode" option's "server" value has been removed since server mode isn't supported (and never has been). This could potentially affect existing users who have had "mode => server" set but in reality have been using client mode all along.
- The "url" option is now mandatory.
- 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
