### Changed

## [0.3.1] - 2015-12-29
### Changed

- Update metrics-es-cluster.rb to use `_stats` api instead of `/_count?q=*:*` see [Unbound wildcard range query cripples es on larger installs #20](https://github.com/sensu-plugins/sensu-plugins-elasticsearch/issues/20)

## [0.3.0] - 2015-11-18
### Changed

### Added
- Add check-es-circuit-breakers.rb, to alert when circuit breakers have been tripped

## [0.2.0] - 2015-10-15
### Changed
- cluster-status check: added a new `status_timeout` option that will use elasticsearch's [`wait_for_status` parameter](https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-health.html#request-params) and wait up to the given number of seconds for the cluster to be green. This pervents false alerting during normal elasticsearch operations.
