Elastic Stack 8.0.0-rc2, the second release candidate following rc1, has been announced, with a reminder that it is not yet suitable for production use and may not be compatible with future or past preview releases or the eventual 8.0.0 general availability. Users are encouraged to participate in the Pioneer Program by testing various components of the Elastic Stack, such as Elasticsearch, Kibana, Beats, Logstash, and APM, and reporting any bugs they encounter in the relevant repositories with a "Pioneer Program" label. Support for upgrade preparations is available through Elastic's forums and community Slack channel.
