2.3.0

• #106 Introduced new MetricsTestKit module that allows asserting certain metrics have been emitted etc.
  • we will provide more documentation soon; meanwhile you can use this test as reference for how to use the testkit here's how one uses it for those curious https://github.com/apple/swift-cluster-membership/blob/main/Tests/SWIMTests/SWIMMetricsTests.swift

2.2.0

New addition allowing for floating point counters. This API will be right away supported by SwiftPrometheus, other libs may follow.

SemVer Minor

New API:

• Add FloatingPointCounter which allows reporting floating point metrics when necessary. Thanks @rauhul!

2.1.1

A minor new API to enable SystemMetrics from the new swift-metrics-extras (coming soon) repository.

SemVer Minor

New API:

• Expose MetricsSystem.withWriterLockso it can be invoked by alternate "bootstrap" functions, such as SystemMetrics; #86 Thanks @MrLotU !

2.1.0

New API:

• Timer.recordInterval(since:) for easier reporting of time since a "start" DispatchTime #83 - thank you @slashmo!

SemVer Patch

• Metrics now include their labels when printed to ease debugging #82

swift-metrics 2.0.0

SemVer Major

• Add microseconds to the TimeUnit enum #64

Important note: The 1.x (previous) version of swift-metrics included a TimeUnit enum which was missing a microseconds case. Since adding a case to an enum is an API breaking change, we needed to release
this change as sever 2.0.0. We also used this opportunity to change the enum to a struct so we can add more time unit without breaking the API. That said, since 1.x and 2.x are almost API compatible, TimeUnit is not used by swift-metrics directly and only used by few libraries that depend on it, most libraries should use the following dependency to avoid a fragmentation of ecosystem:

.package(url: "https://github.com/apple/swift-metrics.git", "1.0.0" ..< "3.0.0")
