+
+Features:
+
+* allow tracing multiple mtr destinations at once
+  via mtr jobs file

+* add -flag.deprecatedMetrics to render deprecated metrics.
+  helps with transition time until deprecated metrics are 
+  gone

+| mtr_report_loss_gauge        | mtr_report_loss             |
+| mtr_report_best_gauge        | mtr_report_best             |

+| mtr_report_stdev_gauge       | mtr_report_stdev            |
+
+Note: mtr_report_duration_seconds not only changed its name, but also
+the unit: its **seconds** now, not **milliseconds** anymore.
+
+With mtr-exporter:0.4.0 the deprecated ones will be removed.
+Use -flag.deprecatedMetrics to have them exposed in the /metrics
+response.
+
+* internal: code adjustments, satisfying varios linters, code-quality
+  reporters, vulnerability checkers etc
+* internal: build system
