+## 2.9.0 (2018-07-17)
+
+### Notes
+
+- Elasticsearch 6 Support
+- icinga health check supports minimum version parameter, ido thresholds for query rate, dummy check is executed in-memory, avoids plugin call
+- `ApplicationVersion` constant in the configuration
+- Setup wizards: global zone, disable conf.d inclusion, unified parameter handling
+- TTL support for check results, pretty formatting for REST API queries
+- TLS support for IDO PostgreSQL
+- Improvements for check scheduling, concurrent checks with command endpoints, downtime notification handling, scheduled downtimes and memory handling with many API requests
