* 7.1.0
- Added back .NET Standard 2.0 support as some customers had a hard dependency on .NET Standard 2.0 (despite not being a documented feature even earlier).
- Added (Observable)UpDownCounter support to MeterAdapter (.NET 7 specific feature).
* 7.0.0
- .NET Core specific functionality now targeting .NET 6.0 or greater (all previous versions will be end of life by December 2022).
- Relaxed the API restriction that forbade you to create multiple metrics with the same name but different label names. While this is a Prometheus anti-pattern, it is a standard pattern in other metrics technologies and we will allow it in the name of interoperability.
- Added IMetricFactory.WithLabels() to define static labels per-factory and reduce the effort needed by users when defining static labels in specific scopes.
- Added automatic metric expiration feature, to remove timeseries when they are no longer used after a while. This improves interoperability with other metrics technologies such as .NET Meters.
- (Breaking change) Rewrite of the MeterAdapter functionality to bridge .NET 6 metrics to Prometheus. API remains equivalent, though options class changed. Output format (what metrics are published) is completely different. Now it translates metric names (instead of putting them in labels) and preserves tags (labels) provided via the .NET Meters API. Added sample project to demonstrate functionality. Ref #359
- (Breaking change) Dropped support for .NET Standard 2.0 - now will target specifically .NET 6.0 and .NET Framework 4.6.2. This was already documented before but there was "unofficial" support also for .NET Standard remaining. This is now removed.
- (Breaking change) EventCounterAdapter output format changed to translate counters to Prometheus metrics and to improve usability by publishing both counters and gauges from ambiguous event counters.
- EventCounterAdapter and MeterAdapter are now enabled on startup by default.
- Added some debug metrics to indicate the number of metric families, instances and timeseries being exported by prometheus-net.
- Added typical benchmark results to readme for easy reference, and to show relative speed of the simple versus complex instruments.
- Removed MetricConfiguration.StaticLabels because it had negative performance impact on many code paths that did not use it. The same functionality can be manually implemented in user code. Static labels remain available on registry and factory level.
- When a before-collection metrics update callback throws an exception, it is now logged and ignored instead of breaking all metrics collection.
- EventCounterAdapter now defaults to Informational events only, for reduced performance overhead. Can be configured via callback.
* 6.0.0
- Dropped library support for unsupported .NET runtime versions (.NET 2.1).
- If Razor Pages is enabled, the "page" label is now automatically added to the default HTTP server metrics, unless there is a user-defined label already present with this name.
- The "endpoint" label is now automatically added to the default HTTP server metrics, containing this endpoint routing route pattern of the request, unless there is a user-defined label already present with this name.
- Added integration with .NET EventCounters, which can now be easily exposed as Promtheus metrics (see EventCounterAdapter class).
- Added integration with .NET Meters, which can now be easily exposed as Promtheus metrics (see MeterAdapter class).
- Added ReplaceOnPush option to MetricPusher #305 #322.
- Minimum .NET Framework version is now 4.6.2.
* 5.1.0
- Add support for adding custom label value providers to HTTP server metrics. #347
* 5.0.2
- Bugfix: HttpClientMetrics under concurrent load with long-running requests were leading to broken response streams. #336
* 5.0.1
- Bugfix: PowersOfTenDividedBuckets did not work with >= 10 buckets due to overlap. Now skips overlapping region of generated series.
* 5.0.0
- Added HTTP client metric that measures the response duration (time until response content reading is finished).
- Added "client" label containing the name of HTTP client to HTTP client metrics.
- Added "code" label with HTTP response code to HTTP client metrics. #299
- HTTP client metrics now count responses when they are completed, not when started, to match with HTTP server metrics. Also renamed metric to httpclient_requests_sent_total since it said "received" previously (due to copy-paste error from HTTP server metrics).
- HTTP client metrics are now published via the netstandard package, without requiring ASP.NET Core. #314
- Added Counter.IncTo[Current]TimeUtc().
* 4.2.0
- Added Histogram.PowersOfTenDividedBuckets()
- Improved accuracy of histogram bucket calculations to reduce the likelyhood of seeing 0.00000000000000000001 offsets from expected value due to floating point math.
- Added ConfigureAwait(false) to MetricHandler to help avoid deadlocks in some rare scenarios. #308
- Fix defect where MetricPusher terminated when HttpClient signaled timeout. #302, #293
- No longer need to manually reference ASP.NET Core SDK in csproj file when installing prometheus-net.AspNetCore library. It gets automatically referenced now. #267
* 4.1.1
- Bugfix: HTTP request metrics in 4.1.0 got broken due to typo in middleware helper.
* 4.1.0
- Fixed HttpClient metrics duration that was incorrectly measured. #265
- prometheus-net.NetFramework.AspNet is now strong named, just like all the other assemblies. #273
- NetFx target is now conditional for Windows builds only, to allow easier development work on nonwindows platforms. #264
- MetricPusher now supports a callback for logging push errors. #186
- Added support for defining static labels on registry or metric level. #256
- Added ICollectorRegistry and IMetricFactory for mocking in test code. #268
- Ignore /metrics URL by default in HTTP request metrics.
- Fix overflow in Summary after observing more than uint.MaxValue events. #277
- Reduce allocations in hot paths. #276, #275
- Added request filtering (authorization) support to standalone MetricServer. #261
* 4.0.0
- Allow arbitrary ASP.NET Core route parameters to be exposed as HTTP metric labels. #225
- Breaking change: some HTTP metrics implementation classes were changed from public to internal. They were never supposed to be public and hopefully nobody ever used them directly. Public documented API did not change.
- Add HttpClient metrics with IHttpClientFactory integration.
* 3.6.0
- Added ASP.NET Core health check publisher for publishing metrics on health check status. #203 #209
- Fixed hang in ASP.NET Web API exporter. #215
- Fixed ASP.NET Web API exporter exporting metrics from the wrong registry. #217

- ASP.NET Core HTTP metrics now capture route data before it is overwritten by an exception handler. #177
- ASP.NET Core HTTP "in progress" metrics now include controller/action labels (ASP.NET Core 3 only).
- Fixed concurrently defect in HTTP metrics that may have caused label values from wrong request to apply. #182
- The HttpListener based MetricServer can now handle more than one concurrent request.
- Added asynchronous "before collect" callbacks, giving user code more flexibility in metric updates.
- Added .Remove() to labeled metric instances for more convenient removal API (previously had to call method on parent instance).
- Added .Unpublish() to labeled metric instances to support temporary unpublishing of a metric, without discarding collected data (e.g. histogram buckets), during periods of data unavailability.
* 3.3.0
- Add ability to filter requests by port number when exporting metrics. #160
* 3.2.1
- Fix NuGet packaging defect that caused reference failures after installing .2.0 on .NET Core 2.1 or newer. #158
* 3.2.0
- Enable custom HTTP client to be used in MetricPusher, allowing for Basic auth and more flexibility. #125
- Add DiagnosticSourceAdapter (.NET Core only). #153
- Improved compatibility with older .NET Framework versions. #155
* 3.1.4
- Fix timezone mismatch in Summary that led to unintended delays in buffer flushing. #149
* 3.1.3
- Fix regression introduced in 3.1.0 where MetricPusher does not always flush metrics before stopping.
* 3.1.2
- Fix defect where Histogram batch observations only incremented sum by one value, instead of entire batch. #147
* 3.1.1
- Added missing UTF-8 charset to Content-Type header, so non-ASCII characters are interpreted correctly by browsers.
* 3.1.0
- Added ICounter.NewTimer() (adds the value to the counter)
- Eliminated some needless allocations when trying to register a metric that is already registered. #134
- Added IHistogram.Count and IHistogram.Sum to expose aspects of collected data for inspection.
- Added Collector.GetAllLabelValues() to expose the list of child metrics by all their known label values.
- Metric export is now asynchronous internally to be compatible with ASP.NET Core 3.0 default configuration.
- Added CollectorRegistry.CollectAndExportAsTextAsync() to support metric data export via arbitrary custom endpoints.
* 3.0.3
- Now backward compatible with ASP.NET Core 2.1 (was 2.2+)
* 3.0.2
- Fix defect where histogram sum failed to increment.
* 3.0.1
- Fix ObjectDisposedException in MetricPusher.
* 3.0.0
- Added HTTP request metrics for ASP.NET Core.
- Somewhat more realistic examples in readme.
- Metrics exporter is now significantly more CPU and memory-efficient.
- Added Observe(value, count) to histogram metric, enabling multiple observations with the same value to be counted.
- Added CountExceptions() and MeasureInProgress() helper extensions.
- Adjusted API to better conform to Prometheus client library guidelines in terms of default values.
- Breaking change: assemblies are now strong-named.
- Breaking change: removed "windows" from built-in metric names as they are not Windows-specific.
- Breaking change: removed support for protobuf export format (it is no longer used by Prometheus).
- Breaking change: API surface cleaned up, removed some legacy methods, made many internal types actually internal.
- Breaking change: "on demand collectors" concept replaced with simpler "before collect callbacks". Works the same, just less code needed to use it and fewer possible error conditions.
- Breaking change: removed support for "custom collectors", as this was a very special use case that did not benefit at all from the main functionality of the library. Just generate a Prometheus exporter output document yourself if you need to export arbitrary data.
