## [Unreleased]

## [2.0.0] - 2017-08-20
### Breaking Changes
- check-aggregates.rb: Changed the default behaviour to alert with the severity of the aggregated checks.

### Added
- check-aggregates.rb: Added new flag to ignore severities. If --ignore-severity is supplied all non-ok will count for critical, critical_count, warning and warning_count option.

### Fixed
- handler-sensu-deregister.rb: Fix undefined variable in case of API error.

## [1.1.1] - 2017-08-01
### Added
- Ruby 2.4 testing (@Evesy)

### Fixed
- bin/check-aggregate.rb: Fix acquire_aggregate to make it work with sensu-server 1.x.x (@nishiki)

## [1.1.0] - 2017-06-25
### Added
- Add support for client invalidation on deregister handler (@Evesy)

### Fixed
- handler-sensu-deregister.rb: Fix undefined variable in case of API error. (@cyrilgdn)

## [1.0.0] - 2016-07-13
### Added
- metrics-events.rb: new plugin to track number of warnings/critical overtime
- check-aggregates.rb: Added support for new named aggregates introduced in Sensu 0.24
- check-aggregates.rb: Added misconfiguration check to guard against returning 'ok' status when provided parameters are insufficient
- check-aggregates.rb: Added new flag to honor stashed checks. If -i is supplied and the threshold alert is being used it will remove any checks that are stashed
- check-aggregates.rb: Added -k for https insecure mode
- check-aggregates.rb: Added config option to use environment var SENSU_API=hostname or SENSU_API_URL=hostname:port for -a
- check-aggregates.rb: Added ability to use node down count instead of percentages

### Changed
- check-aggregates.rb: If summarize is set and the threshold output is being used the alert will contain the summarized results
- handler-sensu-deregister.rb: Overrode sensu-plugin's default `filter` method to make it a noop; deregistration events are one-time and shouldn't be filtered

## [0.1.0] - 2016-01-08
### Added
