Micrometer

Micrometer has been upgraded from 1.12.5 to 1.13.3. One of the changes is the use of Prometheus client v1.x, however, Quarkus will keep using the old deprecated v0.x client for longer.

This requires no changes from users.

However, is for some reason you are using the old dependency in some tests:

<dependency>
    <groupId>io.micrometer</groupId>
    <artifactId>micrometer-registry-prometheus</artifactId>
</dependency>

the new one is:

<dependency>
    <groupId>io.micrometer</groupId>
    <artifactId>micrometer-registry-prometheus-simpleclient</artifactId>
</dependency>
