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

2.13.3 (2022-04-14)

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

2.13.2 (2021-11-12)

This version only includes changes needed for the release of Icinga DB 1.0.0 RC2 and doesn't include any other bugfixes or features.

Icinga DB

Prefix command_id with command type #9085
Decouple environment from Icinga 2 Environment constant #9082
Make icinga:history:stream:*#event_id deterministic #9076
Add downtime.duration & service_state.host_id to Redis #9084

Version 2.13.1 also fixes two issues indroduced with the 2.13.0 release.

Security

Add TLS server certificate validation to ElasticsearchWriter, GelfWriter, InfluxdbWriter and Influxdb2Writer (GHSA-cxfm-8j5v-5qr2)

Depending on your setup, manual intervention beyond installing the new versions may be required, so please read the more detailed information in the release blog post carefully

2.12.5 (2021-07-15)

Version 2.12.5 fixes two security vulnerabilities that may lead to privilege escalation for authenticated API users. Other improvements include several bugfixes related to downtimes, downtime notifications, and more reliable connection handling.

Security

2.12.3 (2020-12-15)

Version 2.12.3 resolves a security vulnerability with revoked certificates being renewed automatically ignoring the CRL.

This version also resolves issues with high load on Windows regarding the config sync and not being able to disable/enable Icinga 2 features over the API.

Security

Fix that revoked certificates due for renewal will automatically be renewed ignoring the CRL (CVE-2020-29663)

When a CRL is specified in the ApiListener configuration, Icinga 2 only used it when connections were established so far, but not when a certificate is requested. This allows a node to automatically renew a revoked certificate if it meets the other conditions for auto renewal (issued before 2017 or expires in less than 30 days).

Because Icinga 2 currently (v2.12.3 and earlier) uses a validity duration of 15 years, this only affects setups with external certificate signing and revoked certificates that expire in less then 30 days.

Bugfixes

Improve config sync locking - resolves high load issues on Windows #8511
Fix runtime config updates being ignored for objects without zone #8549
Use proper buffer size for OpenSSL error messages #8542

Enhancements

On checkable recovery: re-check children that have a problem #8506

2.12.2 (2020-12-01)

Bugfixes

Fix a connection leak with misconfigured agents #8483
Properly sync changes of config objects in global zones done via the API #8474 #8470
Prevent other clients from being disconnected when replaying the cluster log takes very long #8496
Avoid duplicate connections between endpoints #8465
Ignore incoming config object updates for unknown zones #8461
Check timestamps before removing files in config sync #8495

Enhancements

Include HTTP status codes in log #8467

2.12.1 (2020-10-15)

Linux/Unix daemon
Ensure that Icinga 2 does not leak file descriptors to executed commands.
There are 2 processes started instead of previously just one process.
Windows client
Package bundles NSClient++ 0.5.0. ITL CheckCommands have been updated too.
Allow to configure the user account for the Icinga 2 service. This is useful if several checks require administrator permissions (e.g. check_update.exe)
Bugfixes for check plugins
Cluster and API
Provide location information for objects and templates in the API
Improve log message for ignored config updates
Fix cluster resync problem with API created objects (hosts, downtimes, etc.)
Fix that API-created objects in a global zone are not synced to child endpoints
Notifications
Several bugfixes for downtime, custom and flapping notifications
New ITL CheckCommands: logstash, glusterfs, iostats
Package builds require a compiler which supports C++11 features (gcc-c++ >= 4.7, clang++)
DB IDO
Schema upgrade required (2.6.0.sql)
This update fixes timestamp columns required by Icinga Web 2 and might take a while. Please ensure to schedule a maintenance task for your database upgrade.
