* In 24.11 we used a custom build of jmx_exporter to resolve a https://github.com/stackabletech/issues/issues/649[performance degradation].
In this release, Java products ship with the fixed upstream https://github.com/prometheus/jmx_exporter/releases/tag/1.1.0[jmx_exporter 1.1.0] which includes https://github.com/prometheus/jmx_exporter/pull/1009[the fix].
* In 24.11, HDFS metrics suffixed with `+_total+`, `+_created+`, and `+_info+` were not exported by the jmx_exporter.
With this release, metrics suffixed with `+_total+`, e.g. `+hadoop_namenode_files_total+`, are emitted again.
Metrics originally suffixed with `+_created+` and `+_info+` are now suffixed with `+_created_+` and `+_info_+` to be OpenMetrics compliant.
