Version 7.17.1 of the Elastic Stack has been released, offering improvements and crucial fixes, including a patch for a potential security vulnerability and solutions to several upgrade issues from version 7.17 to 8.x. The update addresses problems such as nodes failing to start during system index migration, errors in running system index migrations, and migration failures of the internal .tasks index originally created in version 6.x. Users planning to upgrade to 8.x are advised to install this version first to avoid known migration issues. Detailed information on the fixes and changes can be found in the release notes for Elastic Stack components like Elasticsearch, Kibana, Beats, Logstash, Elastic Enterprise Search, Elastic Observability, APM, and Elastic Security.
