This release has a (minor) breaking change in the simpleclient_hotspot module, fixing an incompatibility with OpenMetrics:
The metric jvm_classes_loaded from the ClassLoadingExports was renamed to jvm_classes_currently_loaded #681. The reason is that there is another metric named jvm_classes_loaded_total, and in OpenMetrics this resulted in a name conflict because the base name jvm_classes_loaded was the same, see github.com/prometheus/jmx_exporter/issues/621.
[ENHANCEMENT] add support for Jakarta Servlet, implemented in the new simpleclient_servlet_jakarta module #647. Thanks @mmadoo for the initial PR.
[ENHANCEMENT] provide a way for filtering metrics by name / name prefix. This can be configured either in the HTTPServer, or in the Servlet exporter (both javax and Jakarta). For example, if some JMX metrics cause performance issues, this can be used for excluding these metrics #680.
[ENHANCEMENT] for the Servlet filter (both javax and Jakarta): Add a parameter to strip the deployment path from the path label #639. Thanks @lapo-luchini !
[ENHANCEMENT] Add HTTP Authentication to the HTTPServer #682. Thanks @dhoard.
[BUGFIX] Use <packaging>bundle</packaging> everywhere so that client_java works with OSGI again #678. Thanks @bigmarvin.
[BUGFIX] use the correct name for the metric type gaugehistogram in OpenMetrics (previously this was wrongly named gauge_histogram)
