Breaking Changes

APM Server is built on top of libbeat. As such, any breaking change in libbeat is also considered to be a breaking change in APM Server.

There are no breaking changes in APM Server. However, a previously hardcoded feature is now configurable. Failing to follow these upgrade steps will result in increased span metadata ingestion when upgrading to version 7.7.

Introduced dedicated apm-server.ilm.setup.* flags. This means you can now customize ILM behavior from within the APM Server configuration. As a side effect, setup.template.* settings will be ignored for ILM related templates per event type. See set up ILM for more information.
By default, ILM policies will not longer be versioned. All event types will switch to the new default policy: rollover after 30 days or when reaching a size 50gb. See default policy for more information.
To make use of all the new features introduced in 7.5, you must ensure you are using version 7.5+ of APM Server and version 7.5+ of Kibana.

Removed deprecated Intake v1 API endpoints. Upgrade agents to a version that supports APM Server >= 6.5. More information.
Moved fields in Elasticsearch to be compliant with the Elastic Common Schema (ECS). More information and changed fields.
