WARNING: Version 5.5 of Beats has passed its EOL date.
This documentation is no longer being maintained and may be removed. If you are running this version, we strongly advise you to upgrade. For the latest information, see the current release documentation.
Version 5.1.0 doesn’t exist because, for a short period of time, the Elastic Yum and Apt repositories included unreleased binaries labeled 5.1.0. To avoid confusion and upgrade issues for the people that have installed these without realizing, we decided to skip the 5.1.0 version and release 5.1.1 instead.
