Full Changelog: v1.3.1...v1.3.2

1.3.1 / 2024-05-23

This is just a minor update to the 1.3.0 release:

With the previous releases it was possible to create illegal UNIT names, like new Unit("&^$") or new Unit("total").

This release prevents that (throwing an IllegalArgumentException), and also adds a method PrometheusNaming.sanitizeUnitName(name) for converting arbitrary strings into valid Prometheus UNIT names.

1.3.0 / 2024-05-16

This is the 1.3.0 release of the Prometheus Java client library.

The headline feature is the new prometheus-metrics-exporter-pushgateway module. See https://prometheus.github.io/client_java/exporters/pushgateway/ for documentation.

• [FEATURE] Port PushGateway to client_java 1.x
• [ENHANCEMENT] Run HTTPServer as a Daemon Thread. Thanks @mberndt123.
• [BUGFIX] Fix naming issue in the Dropwizard 5 exporter. Thanks @kingster
• [BUGFIX] Allow metric names with single character
• [ENHANCEMENT] Fix flaky tests. Thanks @dhoard for extensively load testing our build.
• [ENHANCEMENT] Enforce unit suffix in metric name when unit is not null. Thanks @jonatan-ivanov
• [ENHANCEMENT] Explicit DuplicateLabelsException when creating MetricSnapshot

Thanks to everyone who contributed.
