v3.8.4

What's Changed

This release contains several improvements on the servlet instrumentation contributed by @j-denner. It also features an improvement for the OpenTelemetry Dynatrace exporter: By default the preferred aggregation temporality is now set to always_delta instead of the delta_preferred provided by the OpenTelemetry SDK. The difference is, that the exporter will also use delta aggregation temporality for up-and-down counters. This is necessary, since Dynatrace will otherwise drop metrics of this type. You can switch the aggregation temporality with system property otel.exporter.dynatrace.metrics.temporality.preference.
