**********
* The Prometheus metric creation has changed as user does not need to have a separate
struct :c:struct:`prometheus_metric` any more. This means that the Prometheus macros
:c:macro:`PROMETHEUS_COUNTER_DEFINE`, :c:macro:`PROMETHEUS_GAUGE_DEFINE`,
:c:macro:`PROMETHEUS_HISTOGRAM_DEFINE` and :c:macro:`PROMETHEUS_SUMMARY_DEFINE`
prototypes have changed. (:github:`81712`)
