Details
This change updates all instances of vulnerability.package to the ECS standard package fieldset. For more information, refer to (#164651).

Details
The advanced setting which hides ES|QL from the UI has been renamed from discover:enableESQL to enableESQL. It is enabled by default and must be switched off to disable ES|QL features from your Kibana applications. For more information, refer to (#182074).

Details
These functions have been removed from ES|QL queries as they are not supported. Errors would be thrown when trying to use them. For more information, refer to (#174674).

Details
Rate limiting was added to the upload api/fleet/epm/packages endpoint. For more information, refer to #184036.

Impact
If you do two or more requests in less than 10 seconds, the subsequent requests fail with 429 Too Many Requests. Wait 10 seconds before uploading again. This change could potentially break automations for users that rely on frequent package uploads.

Details
The Kafka output no longer supports conditional topics. For more information, refer to (#176879).

Details

Integration content installed by Fleet is no longer editable. This content is tagged with Managed in the Kibana UI, and is Elastic managed. This content cannot be edited or deleted. However, managed visualizations, dashboards, and saved searches can be cloned. The clones can be customized.

When cloning a dashboard the cloned panels become entirely independent copies that are unlinked from the original configurations and dependencies.

For managed content relating to specific visualization editors such as Lens, TSVB, and Maps, the clones retain the original reference configurations. The same applies to editing any saved searches in a managed visualization.

For more information, refer to (#172393).

Details
Improve config output validation to not allow to defining multiple default outputs in Kibana configuration. For more information, refer to (#167085).

To configure xpack.fleet.agents.fleet_server.hosts and xpack.fleet.agents.elasticsearch.hosts on the Fleet UI, avoid configuring the settings in kibana.yml.

Details
For package policy upgrades, the packagePolicy upgrade endpoint format supports a mutative upgrade operation (when dryRun: false) and a read-only dry run operation (when dryRun: true):

 POST /package_policies/upgrade
 {
   packagePolicyIds: [...],
   dryRun: false
 }

For more information, refer to #118854.

Impact
The endpoint is now split into two separate endpoints:

Impact
The default timezone is UTC. To change the timezone, set logging.timezone: false in kibana.yml. Change the timezone when the system, such as a docker container, is configured for a nonlocal timezone.

Details
Time-based interval index patterns were deprecated in 5.x. In 6.x, you could no longer create time-based interval index patterns, but they continued to function as expected. Support for these index patterns has been removed in 8.0. For more information, refer to #35173

Impact
You must migrate your time_based index patterns to a wildcard pattern. For example, logstash-*.

Details

Details
APM Node.js and RUM JavaScript anomaly detection job modules have been removed. For more information, refer to #119945.

Impact
When you upgrade to 8.0.0, you are unable to create and view the APM Node.js and RUM JavaScript jobs in Machine Learning.

Details
Machine learning features are included as base privileges. For more information, refer to #115444.

Impact
If you do not want to grant users privileges to machine learning features, update Users and Roles.

Details
The Osquery Kibana privilege has been updated, so that when the Privileges for all features level is set to All, this now applies All to Osquery privileges as well. Previously, users had to choose the Customize option to grant any access to Osquery. For more information, refer to #130523.

Impact
This impacts user roles that have Privileges for all features set to All. After this update, users with this role will have access to the Osquery page in Kibana. However, to use the Osquery feature fully, these requirements remain the same: users also need Read access to the logs-osquery_manager.result* index and the Osquery Manager integration must be deployed to Elastic Agents.

Details
Unknown saved object types now cause Kibana migrations to fail. For more information, refer to #107678.

Impact
To complete the migration, re-enable plugins or delete documents from the index in the previous version.

Details

Details
The /api/security/v1/saml route has been removed and is reflected in the kibana.yml server.xsrf.whitelist setting, Elasticsearch, and the Identity Provider SAML settings. For more information, refer to #47929

Impact
Use the /api/security/saml/callback route, or wait to upgrade to 8.0.0-alpha2 when the /api/security/saml/callback route breaking change is reverted.

Details
To provide the maximum level of protection for most installations, the csp.strict config is now enabled by default. Legacy browsers not supported by Kibana, such as Internet Explorer 11, are unable to access Kibana unless explicitly enabled. All browsers officially supported by Kibana do not have this issue. For more information, refer to #41700

Impact
To enable support for legacy browsers, set csp.strict: false in kibana.yml. To effectively enforce the security protocol, we strongly discourage disabling csp.strict unless it is critical that you support Internet Explorer 11.

Details
After you extract an archive, the output directory no longer includes the target platform. For example, kibana-8.0.0-linux-aarch64.tar.gz produces a kibana-8.0.0 folder. For more information, refer to #93835.

Impact
To use the new folder, update the configuration management tools and automation.

Details
The default support for TLS v1.0 and v1.1 has been removed. For more information, refer to #90511.

Impact
To enable support, set --tls-min-1.0 in the node.options configuration file. To locate the configuration file, go to the kibana/config folder or any other configuration with the KBN_PATH_CONF environment variable. For example, if you are using a Debian-based system, the configuration file is located in /etc/kibana.

Details
All supported operating systems use systemd service files. Any system that doesn’t have service aliased to use kibana.service should use systemctl start kibana.service instead of service start kibana. For more information, refer to #74424.

Impact
If your installation uses .deb or .rpm packages with SysV, migrate to systemd.

Details
In previous versions, all events are logged in json when logging.json:true. With the new logging configuration, you can choose the json and pattern output formats with layouts. For more information, refer to #42353.

Impact
To restore the previous behavior, configure the logging format for each custom appender with the appender.layout property in kibana.yml. There is no default for custom appenders, and each appender must be configured explicitly.

Details
The API endpoint for downloading a CSV file from a saved search in the Dashboard application has changed to reflect the fact that this is an internal API. The previous API path of /api/reporting/v1/generate/immediate/csv_searchsource has been changed to /internal/reporting/generate/immediate/csv_searchsource. For more information, refer to #162288.

Details
CSV reports now use PIT instead of Scroll. Previously generated CSV reports that used an index alias with alias-only privileges, but without privileges on the alias referenced-indices will no longer generate. For more information, refer to #158338.

Impact
To generate CSV reports, grant read privileges to the underlying indices.

Details
The /api/reporting/generate/csv endpoint has been removed. For more information, refer to #121435.

Details
Removes the apm_user role. For more information, check #132790.

Impact
The apm_user role is replaced with the viewer and editor built-in roles.

Details
We introduced a breaking change in the SLO features that will break any SLOs created before 8.12. These SLOs have to be manually reset through an API until we provide a UI for it. The data aggregated over time (rollup) is still available in the SLI v2 index, but won’t be used for summary calculation when reset.

The previous summary transforms summarizing every SLOs won’t be used anymore and can be stopped and deleted:

Be aware that when installing a new SLO (or after resetting an SLO), we install two transforms (one for the rollup data and one that summarize the rollup data). Do not delete the new slo-summary-{slo_id}-{slo_revision} transforms. For more information, refer to (#172224).

Details

If some SLOs have been installed in a prior version at 8.10, they won’t work after migrating to 8.10. There are two approaches to handle this breaking change. The recommended route is to delete all SLOs before migrating to 8.10. The alternative is to migrate to 8.10 and manually remove the SLOs.

Removing SLOs before migrating to 8.10

Use the SLO UI or the SLO delete API to delete all existing SLOs. This takes care of the saved object, transform and rollup data. When all SLOs have been deleted, then delete the residual rollup indices: .slo-observability.sli-v1*. Note that this is v1.

Removing SLOs after migrating to 8.10

After migrating to 8.10, the previously created SLOs won’t appear in the UI because the API is using a new index. The previously created SLOs still exist, and associated transforms are still rolling up data into the previous index .slo-observability.sli-v1*. The SLO delete API can’t be used now, so remove the resources resources manually:

Details
The Uptime app now gets hidden from the interface when it doesn’t have any data for more than a week. If you have a standalone Heartbeat pushing data to Elasticsearch, the Uptime app is considered active. You can disable this automatic behavior from the advanced settings in Kibana using the Always show legacy Uptime app option. For synthetic monitoring, we now recommend to use the new Synthetics app. For more information, refer to #159118

Details
Data from browser monitors and monitors of all types created within the Synthetics App or via the Elastic Synthetics Fleet Integration will no longer appear in Uptime. For more information, refer to #159012
