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 1.21.1 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 1.21.1. 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.

    • Server: header in responses from from Humio HTTP server now includes (Vhost, NodeRole) after the version string.

    • Improve performance of "decrypt step" in downloads from bucket storage
