This list summarizes the most important breaking changes in APM. For the complete list, go to APM breaking changes.

The following breaking changes are introduced in APM version 8.2.0:

APM Server now emits events with event.durationedit

APM Server no longer emits events with a transaction.duration.us or span.duration.us. Instead, events are emitted with an event.duration. An ingest pipeline sets the legacy <event>.duration.us field and removes the event.duration.

This change will impact users who are not using APM Server’s Elasticsearch output or the packaged ingest pipeline. For details, see PR #7261.

Removed observer.version_majoredit

The field observer.version_major is non-standard and existed only for the APM UI to filter out legacy docs (versions <7.0). This check is no longer performed, so the field has been removed.

For details, see PR #7399.

APM Server no longer ships with System V init scripts or the go-daemon wrapperedit

As of version 8.1.0, all Linux distributions supported by APM Server support systemd. As a result, APM Server no longer ships with System V init scripts or the go-daemon wrapper; use systemd instead.

For details, see PR #7576.

Deprecated 32-bit architecturesedit

APM Server support for 32-bit architectures has been deprecated and will be removed in a future release.
