Important Information about Upgrading

Beginning with version 1.17.0, if your current version of Humio is not directly able to upgrade to the new version, you will get an error if you attempt to start up the incompatible version. The 1.23.0 release is only compatible with Humio release 1.16.0 and newer. This means that you will have to ensure that you have upgraded at least to 1.16.0 before trying to upgrade to 1.23.0. In case you need to do a rollback, this can also ONLY happen back to 1.16.0 or newer. Rolling directly back to an earlier release can result in data loss.

Humio will make some internal logs available in a new repository called humio-activity. This is meant for logs that are relevant to users of Humio, as compared to logs that are only relevant for operators. The latter logs are still put into the humio repository. For this release, only new log events will be put into humio-activity, but in later releases, some existing log events that are relevant for users, will be put into the humio-activity repository instead of the humio repository.

For cloud users, the logs for your organization can be accessed through the humio-organization-activity view.

For on-prem users, the logs can be accessed directly through the humio-activity repository. They are also output into a new log file named humio-activity.log which can be ingested into the humio repository, if you want it available there as well. If you do and you are using the Insights Package, you should upgrade that to version 0.0.4. For more information, see LogScale Internal Logging.

Humio has decided to adopt an evolutionary approach to its GraphQL API, meaning that we will strive to do only backwards compatible changes. Instead of making non-backwards compatible changes to existing fields, we will instead add new fields alongside the existing fields. The existing fields will be deprecated and might be removed in some later release. We reserve the right to still do non-backwards compatible changes, for instance to fix security issues.

For new experimental features, we will mark the corresponding GraphQL fields as PREVIEW. There will be no guarantees on backwards compatibility on fields marked as PREVIEW.

Deprecated and preview fields and enum values will be marked as such in the GraphQL schema and will be shown as deprecated or preview in the API Explorer. Apart from that, the result of running a GraphQL query using a deprecated or preview field will contain a new field extensions, which contains a field deprecated with a list of all deprecated fields used in the query and a field preview with a list of all preview fields used in the query.

Example:

{
  "data": "...",
  "extensions": {
    "deprecated": [
      {
        "name": "alert",
        "reason": "[DEPRECATED: Since 2020-11-26. Deprecated since 1.19.0. Will be removed March 2021. Use 'searchDomain.alert' instead]"
      }
    ]
  }
}

Deprecated fields and enum values will also be noted in the release note, when they are first deprecated. All use of deprecated fields and enum values will also be logged in the Humio repository humio-activity. They will have #category=GraphQL, subCategory=Deprecation and #severity=Warning. If you are using the API, consider creating an alert for such logs.

Removed Support for CIDR Shorthand

Previous version of Humio supported a shorthand for IPv4 CIDR expressions. For example 127.1/16 would be equivalent to 127.1.0.0/16. This was contrary to other implementations like the Linux function inet_aton, where 127.1 expands to 127.0.0.1. Support for this shorthand has been removed and the complete address must now be written instead.

Deprecation

Items that have been deprecated and may be removed in a future release.

• Deprecated GraphQL mutations addAlertLabel, removeAlertLabel, addStarToAlert and removeStarFromAlert as they did not follow the standard for mutation input.
