  • ⚠ > WARNING! - If you are using a 3.x or earlier release, please refer to the v4.0.0 Breaking Changes.

    🚀 ElastiFlow v4.0.1 is a minor release. No migration of data from v4.0.0 to v4.0.1 is required.

    ⚡️ Updates

    • ⚡️ Update IP reputation dictionary

Previous changes from v4.0.0

  • ⚠ > WARNING! - ElastiFlow v4.0.0 is a major release, and now supports Elastic Common Schema (ECS). Due to significant data model changes there is no upgrade/migration from ElastiFlow 3.x. You should either remove all 3.x indices or deploy ElastiFlow 4.0.0 to a separate environment.

    💥 Breaking Changes

    🚀 ElastiFlow v4.0.0 is built for Elasticsearch and Kibana 7.8.1 and later. No earlier versions will be supported. Please use a prior ElastiFlow release if you cannot yet upgrade to Elastic Stack 7.8.1+.

    🚀 ElastiFlow v4.0.0 takes advantage of X-Pack Basic features, such as the Maps, SIEM and Logs apps, as well as Index Lifecycle Management (ILM). This means that you must use at least the X-Pack Basic licensed release of the Elastic Stack. The pure Apache 2.0 licensed release of the Elastic Stack will not work without disabling many features.
