2.0

• Background metrics resolution. Configure collector and receiver and materialize collected metrics on regular basis
• Tagged metrics. Persist ant tags to metrics directly
• Groupless metrics. Metric groups are gone. You can dynamically group metrics by tags and propagate tags to group level for certain formatters
• Simplified metrics mutator. Just call the method, no need on manual metrics operations.
