+### Enhancements
+
+* Core
+ * Rewrite Network Stack (cluster, REST API) based on Boost Asio, Beast, Coroutines
+ * Technical concept: #7041
+ * Requires package updates: Boost >1.66 (either from packages.icinga.com, EPEL or backports). SLES11 & Ubuntu 14 are EOL.
+ * Require TLS 1.2 and harden default cipher list
+ * Improved Reload Handling (umbrella process, now 3 processes at runtime)
+ * Support running Icinga 2 in (Docker) containers natively in foreground
+ * Quality: Use Modern JSON for C++ library instead of YAJL (dead project)
+ * Quality: Improve handling of invalid UTF8 strings
+* API
+ * Fix crashes and problems with permission filters from recent Namespace introduction #6785 (thanks Elias Ohm) #6874 (backported to 2.10.5)
+ * Locks and stalled waits are fixed with the core rewrite in #7071
+ * schedule-downtime action supports `all_services` for host downtimes
+ * Improve storage handling for runtime created objects in the `_api` package
+* Cluster
+ * HA aware features & improvements for failover handling #2941 #7062
+ * Improve cluster config sync with staging #6716
+* Checks & Notifications
+ * Ensure that notifications during a restart are sent
+ * Immediately notify about a problem after leaving a downtime and still NOT-OK
+ * Improve reload handling and wait for features/metrics
+ * Store notification command results and sync them in HA enabled zones #6722
+* DSL/Configuration
+ * Add getenv() function
+ * Fix TimePeriod range support over midnight
+ * `concurrent_checks` in the Checker feature has no effect, use the global MaxConcurrentChecks constant instead
+* CLI
+ * Permissions: node wizard/setup, feature, api setup now run in the Icinga user context, not root
+ * `ca list` shows pending CSRs by default, `ca remove/restore` allow to delete signing requests
+* ITL
+ * Add new commands and missing attributes - thanks to all contributors!
+* Windows
+ * Update bundled NSClient++ to 0.5.2.39
+ * Update agent installer and OpenSSL
+* Documentation
+ * Service Monitoring: How to create plugins by example, check commands and a modern version of the supported plugin API with best practices.
+ * Features: Better structure on metrics, and supported features.
+ * Basics: Rename `Custom Attributes` to `Custom Variables`.
+ * Basics: Refine explanation of command arguments.
+ * Distributed: Reword `Icinga client` into `Icinga agent` and add new images for scenarios and modes.
+ * Security: Add TLS v1.2+ requirement, hardened cipher lists
+ * Technical Concepts: TLS Network IO, Cluster Feature HA, Cluster Config Sync, Core Reload Handling.
+ * Development: Rewritten for better debugging and development experience for contributors including a style guide. Add nightly build setup instructions.
