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

Windows

• Update the bundled version of Boost to 1.79.0. #9359

Icinga 2 v2.13.3

This version includes bugfixes for many features of Icinga 2, including fixes for multiple crashes. It also includes a number of fixes and improvements for Icinga DB.

API

• The /v1/config/stages endpoint now immediately rejects parallel config updates instead of accepting and then later failing to verify and activate them. #9328

Certificates

• The lifetime of newly issued node certificates is reduced from 15 years to 397 days. #9337
• Compare cluster certificate tickets in constant time. #9333

Notifications

• Fix a crash that could happen while sending notifications shortly after Icinga 2 started. #9124
• Fix missing or redundant notifications after certain combinations of state changes happened while notifications were suppressed, for example during a downtime. #9285

Checks and Commands

• Fix a deadlock when processing check results for checkables with dependencies. #9228
• Fix a message routing loop that can happen for event commands that are executed within a zone using command_endpoint that resulted in excessive execution of the command. #9260

Downtimes

• Fix scheduling of downtimes for all services on child hosts. #9159
• Creating fixed downtimes starting immediately now send a corresponding notification. #9158
• Fix some issues involving daylight saving time changes that could result in an hour missing from scheduled downtimes. This fix applies to time periods as well. #9238

Configuration

• Fix the evaluation order of default templates when used in combination with apply rules. Now default templates are imported first as stated in the documentation and as it already happens for objects defined without using apply. #9290

IDO

• Fix an issue where contacts were not written correctly to the notification history if multiple IDO instances are active on the same node. #9242
• Explicitly set the encoding for MySQL connections as a workaround for changed defaults in Debian bullseye. #9312
• Ship a MySQL schema upgrade that fixes inconsistent version information in the full schema file and upgrade files which could have resulted in inaccurate reports of an outdated schema version. #9139

Performance Data Writers

• Fix a race condition in the InfluxDB Writers that could result in a crash. #9237
• Fix a log message where Influxdb2Writer logged as InfluxdbWriter. #9315
• All writers no longer send metrics multiple times after HA failovers. #9322

Build

• Fix the order of linker flags to fix builds on some ARM platforms. #9164
• Fix a regression introduced in 2.13.2 preventing non-unity builds. #9094
• Fix an issue when building within an unrelated Git repository, version information from that repository could incorrectly be used for Icinga 2. #9155
• Windows: Update bundled Boost version to 1.78.0 and OpenSSL to 1.1.1n #9325

Internals

• Fix some race conditions due to missing synchronization. These race conditions should not have caused any practical problems besides incorrect numbers in debug log message. #9306
• Move the startup.log and status files created when validating incoming cluster config updates to /var/lib/icinga2/api and always keep the last failed startup.log to ease debugging. #9335

Icinga DB

• The severity attribute was updated to match the sort order Icinga Web 2 uses for the IDO. The documentation for this attribute was already incorrect before and was updated to reflect the current functionality. #9239 #9240
• Fix the is_sticky attribute for comments. #9303
• Fix missing updates of is_reachable and severity in the state tables. #9241
• Removing an acknowledgement no longer incorrectly writes comment history. #9302
• Fix multiple issues so that in an HA zone, both nodes now write consistent history. #9157 #9182 #9190
• Fix that history events are no longer written when state information should be updated. #9252
• Fix an issue where incomplete comment history events were generated. #9301
  Note: when removing comments using the API, the dedicated remove-comment action should be used instead of the objects API, otherwise no history event will be generated.
• Fix handling of non-integer values for the order attribute of command arguments. #9181
  Note: You should only specify integer values for order, other values are converted to integer before use so using fractional numbers there has no effect.
• Add a dependency on icingadb-redis.service to the systemd service file so that Redis is stopped after Icinga 2. #9304
• Buffer history events in memory when the Redis connection is lost. #9271
• Add the previous soft state to the state tables. #9214
• Add missing locking on object runtime updates. #9300
