### Bug
* [#4952](https://github.com/icinga/icinga2/issues/4952) (API, CLI): Icinga crashes while trying to remove configuration files for objects which no longer exist
* The "bottom up" client configuration mode has been deprecated. Check [#13255](https://dev.icinga.com/issues/13255) for additional details and migration.
* There are 2 processes started instead of previously just one process.
* Windows client
* Package bundles NSClient++ 0.5.0. ITL CheckCommands have been updated too.

* Bugfixes for check plugins
* Cluster and API
* Provide location information for objects and templates in the API
* Improve log message for ignored config updates
* Fix cluster resync problem with API created objects (hosts, downtimes, etc.)
* Fix that API-created objects in a global zone are not synced to child endpoints
* Notifications
* Several bugfixes for downtime, custom and flapping notifications
* New ITL CheckCommands: logstash, glusterfs, iostats
* Package builds require a compiler which supports C++11 features (gcc-c++ >= 4.7, clang++)
* DB IDO
* Schema upgrade required (2.6.0.sql)
* This update fixes timestamp columns required by Icinga Web 2 and might take a while. Please ensure to schedule a maintenance task for your database upgrade.
