    • 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 on Linux, Unix and Windows from Nessus scans #7431
  • 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
  • Fixed that same downtime/comment objects would be synced again in a cluster loop #7198

  • 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

• 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
• Windows
  • Update bundled NSClient++ to 0.5.2.39
  • Refine agent setup wizard & update requirements to .NET 4.6
