Breaking Changes

• Remove CheckResultReader (which has been deprecated since v2.9). #9714
• Remove StatusDataWriter (which has been deprecated since v2.9). #9715
• ElasticsearchWriter: drop support for Elasticsearch < v7. #9812
• Consider a checkable unreachable once one Dependency fails. Previously all of them had to fail. (Consult the upgrading docs.) #8218
• API: reject config modifications during reload with HTTP status 503. #9445
• icinga2 daemon: to reduce config load time, write file needed by icinga2 object list only if --dump-objects is given. #9586 #9591
• Default email notification scripts: link to Icinga DB Web, not the monitoring module. (Consult the upgrading docs.) #9742 #9757
• API: for security reasons hide TicketSalt in /v1/variables. #7863

Icinga 2 Config DSL

• Disallow global variable modification after config commit start (i.e. inside object/apply T "x" { ... }) to reduce config load time. #9740
• Forbid Dependency cycles at config load time. #8389
• Allow only strings in the arrays Host#groups, Service#groups and User#groups. Needed for consistency, especially by the IDO. #9057
• Disallow empty object names. (They worked only partially anyway.) #9409

Windows Agent only

The official MSIs don't include the following features anymore. They weren't intended, tested or needed on Windows and only waste build time, bandwidth and disk space. Both new installations and upgrades are affected.

• ElasticsearchWriter #9704
• GelfWriter #9704
• GraphiteWriter #9704
• InfluxdbWriter and Influxdb2Writer #9704
• OpenTsdbWriter #9704
• PerfdataWriter #9704

We also don't ship the following files anymore. (You can still obtain them manually.)

• NSCP.msi (NSClient++ installer) #9703
• doc/ (Icinga 2 markdown documentation) #9705

On the other hand MSIs are now 75% smaller than before.

Enhancements

• Significantly reduce config load time of large setups. #8118 #9555 #9557 #9572 #9577 #9603 #9608 #9627 #9648 #9657 #9662
• Allow to connect dependencies via redundancy groups. Only parents within one group are assumed to provide redundancy for each other. #8218
• Built-in check command ifw-api, communicates directly with the Icinga for Windows REST API. (Doesn't spawn a PowerShell process for that.) #9062
• JournaldLogger which logs to systemd journal. #9000
• API: POST /v1/objects: allow to discard some previously modified attributes, i.e. to restore the config files' values. #9783
• ElasticsearchWriter: support Elasticsearch v8. #9812
• Support $env.ENV_VAR_NAME$ macros. #8302
• Speed up Icinga DB config dump. #9524
• Default mail notification scripts: also print $host.notes$ and $service.notes$. #9713
• Enable built-in OpenSSL DH parameters to allow DHE TLS ciphers. #9811
• Clean up global default TLS cipher list to improve security. #9809
• Influxdb(2)Writer: write more precise timestamps (nanoseconds). #9599

Bugfixes

• Icinga DB feature: normalize several Redis data not to crash the Go daemon. #9772 #9775 #9792 #9793 #9794 #9805
• Fix parsing of perfdata across multiple lines in plugin output. #8969
• icinga check: fix last reload failure time. #8429 #9827
• Resolve macros inside custom vars of IcingaApplication. #9779
• SELinux: allow Icinga and its plugins to write to syslog. #9688
• ElasticsearchWriter: fix data buffer flush race condition during stop. #9810
• Trigger flexible downtimes not in the past if checkable is already down. #9726
• Send downtime expiration notifications immediately, not after up to a minute. #9726

Cluster

• Don't hang in timed out connection attempt. #9711 #9725
• Fix lost acknowledgements after re-connect. #9718
• cluster-zone check: don't complain about not connected other local zone members if there aren't any. #8595
• Allow agent to update executions delegated to it via /v1/actions/execute-command. #8627

API

• Disallow breaking inter-object relationships by changing relationship attributes at runtime, e.g. Service#host_name. #9407
• Correct several HTTP response status codes. #7958 #9354
• Correct Boolean field types previously reported by /v1/types as Number. #9514

CLI

• icinga2 daemon: fix -DConfiguration.Concurrency= flag which now allows to override the number of threads. #9643
• icinga2 node wizard: avoid unnecessary chown(2) which may fail and abort the wizard. #8744
• Correct several log messages. #8895 #8965 #9663

ITL

Add linux_netdev check command. #9045

Command Argument Changes

• disk: don't pass -m (disk_megabytes) by default. #9642
• disk: pass -X fuse.portal (disk_exclude_type) by default. #9459
• http: support multiple -k (http_header) as array. #8574
• icmp: double defaults for -w (icmp_wpl) and -c (icmp_cpl). #9041
• logfiles: pass --winwarncrit (logfiles_winwarncrit) without argument. #9056
• nwc_health: pass SNMPv3-only args only when using SNMPv3. #9095
• vmware-esx-dc-runtime-tools and vmware-esx-soap-vm-runtime-tools: rename --open-vm-tools to --open_vm_tools_ok (vmware_openvmtools). #9611
