Full Changelog: v0.12.0...v0.13.0

Breaking Changes

• The Prometheus metric message_processing_total has been retired. Please use message_processing_count instead.
• The Prometheus Client added new method overloads for creating metrics. In contrast to previous versions, supplying only one label to params labelNames will result in a different method call with a different return type. As a fix, pass new [] {"someLabel"} instead of "someLabel".
