v2.11.3

Blogpost

This release addresses a critical crash regarding our cluster JSON-RPC connections. This mainly affects users who run large environments and use HA zones. In most cases updating all masters should resolve the problem, but we still recommend updating all Icinga 2 instances.

• 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
