Breaking Changes

• Due to renaming the Go module from armon/go-metrics to hashicorp/go-metrics all libraries within a program that use the global metrics handler will need updating. If not they may be sending metrics to either the old modules global handler or the new modules handler.

What's Changed

• Renamed module to hashicorp/go-metrics
• Add GaugeFloat64 API
• Prevent dogstatsd sink from clobbering the metric key for other sinks

Includes a performance improvement in the Prometheus sink that was identified as wasting CPU time in Nomad where metrics are recorded in a hot code path.

See https://github.com/armon/go-metrics/pull/138

Updates supported Go versions to 1.16, 1.17 and 1.18.

Adds a Shutdown function that attempts to insure buffered metrics are flushed to the underlying sink for short-lived processes. See https://github.com/armon/go-metrics/pull/132 and https://github.com/armon/go-metrics/pull/134.

Note that Shutdown was initially added and released as a 0.3.11 but contained a breaking change for library users that have their own MetricsSink implementation since it added an interface method.

This release retracts the 0.3.11 release and re-introduces the Shutdown change in a backwards compatible manner. See https://github.com/armon/go-metrics/pull/134.

Adds a Shutdown function that attempts to insure buffered metrics are flushed to the underlying sink for short-lived processes. Not all sinks support this. See #132.

Allow multiple Prometheus sink instances in a single process to not conflict. See #129.

Adds a new Stream method that provides a streaming HTTP 1.x handler that will return a news set of metrics every interval.

Fixes a deadlock in InMemSink. #124

Fix behaviour with pre-defined Prometheus metrics where we would reset Gauges and invalidate Summaries after Expiry despite them being pre-declared as always useful values. See https://github.com/armon/go-metrics/pull/123 for more details.

Fixes an issue in Prometheus sink where dynamic labels cause changes to the help message/description which Prometheus doesn't like.
