1.20.1

For highlights and announcements pertaining to this release see: Release Notes > 1.20.1.

The following changes are from the previous release 1.20.0.

• NuGet: OpenTelemetry v1.20.1

  • Fixed a possible race condition on ARM64 when multiple threads record the
    first measurement with no tags, or the first overflow measurement, that could
    cause the measurement to be recorded incorrectly.
    (#​7951)

  • Fixed self-diagnostics preamble redaction of quoted or encoded PEM material
    and prefixed JWTs.
    (#​7955)

  • Fixed default HTTP client log filtering when registering the OTLP log exporter
    through OpenTelemetryLoggerOptions.
    (#​7959)

  • Fixed legacy self-diagnostics logging terminating the process when the log
    file is truncated or the log volume runs out of space.
    (#​7956)

  • Experimental (pre-release builds only): Fixed Logger.EmitLog ignoring
    instrumentation suppression, which could cause recursive exports or deadlocks.
    (#​7961)

  • Fixed delta double counters losing subsequent measurements after a non-finite
    or large value and idle metric points with a NaN value failing to be reclaimed.
    (#​7963)

  • Improve the assignment of values to exponential histogram buckets when the
    value is near a bucket boundary by using a pre-computed lookup table.
    (#​7911)

  • Fixed LogRecords being returned to the shared pool while still queued for
    export when an exporter stops enumerating a single-item or array
    Batch<LogRecord> early which could cause a BatchLogRecordExportProcessor
    on the same provider to export missing or incorrect data.
    (#​7965)

  • Fixed a SuppressInstrumentationScope.Enter() reference count never being
    released when the Activity it was entered for is not recorded, which caused
    all subsequent telemetry in that execution context to be suppressed.
    (#​7966)

  • Self-diagnostics log files, whether configured through OTEL_DIAGNOSTICS.json
    or SelfDiagnosticsOptions, are now always created as new files.

1.20.1-beta.1

The following changes are from the previous release 1.20.0-beta.1.

• NuGet: OpenTelemetry.Exporter.Prometheus.AspNetCore v1.20.1-beta.1

  • Fixed scrape responses being handed to the server in a single write, which
    made the server buffer a full copy of the response for each client that did
    not read it until the request completed or timed out. Responses are now
    written in bounded slices so the server's back-pressure applies.
    (#​7957)

  • Fixed startup scrapes permanently omitting target_info and configured
    resource constant labels from subsequent scrape responses.
    (#​7984)

  • Updated OpenTelemetry core component version(s) to 1.20.1.
    (#​7990)

  See CHANGELOG for details.

• NuGet: OpenTelemetry.Exporter.Prometheus.HttpListener v1.20.1-beta.1

  • Fixed scrape responses being handed to the server in a single write, which
    on Linux and macOS made the listener allocate and hold a full copy of the
    response for each client that did not read it until the request completed or
    timed out. Responses are now written in bounded slices.
    (#​7957)

  • Fixed scrape requests that announce a request body holding a thread pool
    thread after their response had been sent on Linux and macOS for as long as
    the client kept trickling in the body. The connection is now closed after
    responding to a request with a body instead of being kept alive.
    (#​7962)

  • Fixed startup scrapes permanently omitting target_info and configured
    resource constant labels from subsequent scrape responses.
    (#​7984)

  • Updated OpenTelemetry core component version(s) to 1.20.1.
    (#​7990)

  See CHANGELOG for details.

• NuGet: OpenTelemetry.Shims.OpenTracing v1.20.1-beta.1

  • Updated OpenTelemetry core component version(s) to 1.20.1.

  See CHANGELOG for details.

1.20.0

For highlights and announcements pertaining to this release see: Release Notes > 1.20.0.

The following changes are from the previous release 1.19.1.

• NuGet: OpenTelemetry v1.20.0

  • Fixed SuppressInstrumentationScope reference counts leaking between inherited asynchronous execution contexts.
    (#​7803)

  • Self-diagnostic features are explicitly disabled on browser-based platforms (e.g. Blazor) and are now non-functional. Previously, attempting to enable self-diagnostics on such platforms would result in an exception at runtime.
    (#​7799)

  • Added TracerProviderBuilder.ConfigureSampler which receives the resolved Sampler whether set programmatically, via OTEL_TRACES_SAMPLER, or by default, and returns a replacement. Intended for library authors who need to influence sampling without overriding a sampler the application has configured.
    (#​7780)

  • Fixed ResourceBuilder.CreateDefault ignoring OTEL_RESOURCE_ATTRIBUTES and OTEL_SERVICE_NAME environment variables when the host IConfiguration does not contain those settings.
    (#​7855)

  • Added improved self-diagnostics logging to improve the support experience. The new SelfDiagnosticsOptions class configures a rolling file sink and a console sink through the standard options pipeline. Sinks are off by default.
    (#​7588)

  • Fixed a race that could incorrectly route a concurrent metric measurement to the overflow point when its tag set was published as the cardinality limit was reached.
    (#​7804)

  • Added OpenTelemetryLoggerOptions.Version and OpenTelemetryLoggerOptions.SchemaUrl options to set an instrumentation library version and schema URL applied to logs emitted via the Microsoft.Extensions.Logging ILogger integration.
    (#​7727)

  • Fixed LogRecord.CategoryName resetting the current Logger's Version to null when set to a new value.
    (#​7727)

  • Bounded the internal cache of Logger scopes keyed by instrumentation to avoid unbounded growth.
    (#​7727)

  • Fixed the MeterProvider and its IServiceProvider being kept alive after the host is disposed when using Microsoft.Extensions.Diagnostics versions prior to 9.0, which never dispose their MetricsSubscriptionManager (and its underlying MeterListener).
    (#​7924)

  • Fixed a race condition between recording a measurement and collecting a histogram with delta temporality that could cause an empty data point (with a count of zero) to be exported in the next collection cycle.
    (#​7923)

  • Improved metric collection performance after metric streams are removed by compacting metric storage during collection.
    (#​7945)

  See CHANGELOG for details.

• NuGet: OpenTelemetry.Api v1.20.0

  • Added Logger.SchemaUrl and a LoggerProvider.GetLogger overload accepting a schema URL parameter using the new LoggerOptions type.
    (#​7727)

  • Breaking change (pre-release only versions): LoggerProvider's protected TryCreateLogger(string? name, out Logger? logger) extensibility method has been replaced by TryCreateLogger(LoggerOptions options, out Logger? logger). Custom LoggerProvider subclasses that override the previous overload must update to override the new one; the old overload is no longer called.

The following changes are from the previous release 1.19.1-beta.1.

• NuGet: OpenTelemetry.Exporter.Prometheus.AspNetCore v1.20.0-beta.1

  • A scrape request whose connection is aborted, or whose X-Prometheus-Scrape-Timeout-Seconds deadline elapses, now stops waiting for an in-progress metrics collection instead of continuing to wait for it to finish. The collection itself is not cancelled and continues running in the background.
    (#​7856)

• NuGet: OpenTelemetry v1.20.1-rc.1

  • Fixed a possible race condition on ARM64 when multiple threads record the
    first measurement with no tags, or the first overflow measurement, that could
    cause the measurement to be recorded incorrectly.
    (#​7951)

  • Fixed self-diagnostics preamble redaction of quoted or encoded PEM material
    and prefixed JWTs.
    (#​7955)

  • Fixed default HTTP client log filtering when registering the OTLP log exporter
    through OpenTelemetryLoggerOptions.
    (#​7959)

  • Fixed legacy self-diagnostics logging terminating the process when the log
    file is truncated or the log volume runs out of space.
    (#​7956)

  • Experimental (pre-release builds only): Fixed Logger.EmitLog ignoring
    instrumentation suppression, which could cause recursive exports or deadlocks.
    (#​7961)

  • Fixed delta double counters losing subsequent measurements after a non-finite
    or large value and idle metric points with a NaN value failing to be reclaimed.
    (#​7963)

  • Improve the assignment of values to exponential histogram buckets when the
    value is near a bucket boundary by using a pre-computed lookup table.
    (#​7911)

  • Fixed LogRecords being returned to the shared pool while still queued for
    export when an exporter stops enumerating a single-item or array
    Batch<LogRecord> early which could cause a BatchLogRecordExportProcessor
    on the same provider to export missing or incorrect data.
    (#​7965)

  • Fixed a SuppressInstrumentationScope.Enter() reference count never being
    released when the Activity it was entered for is not recorded, which caused
    all subsequent telemetry in that execution context to be suppressed.
    (#​7966)

  • Self-diagnostics log files, whether configured through OTEL_DIAGNOSTICS.json
    or SelfDiagnosticsOptions, are now always created as new files.
    (#​7968)

  • Self-diagnostics messages written to the sinks configured by
    SelfDiagnosticsOptions are now truncated to 16,384 characters so that the

1.20.1-beta.1

The following changes are from the previous release 1.20.0-beta.1.

• NuGet: OpenTelemetry.Exporter.Prometheus.AspNetCore v1.20.1-beta.1

  • Fixed scrape responses being handed to the server in a single write, which
    made the server buffer a full copy of the response for each client that did
    not read it until the request completed or timed out. Responses are now
    written in bounded slices so the server's back-pressure applies.
    (#​7957)

  • Fixed startup scrapes permanently omitting target_info and configured
    resource constant labels from subsequent scrape responses.
    (#​7984)

  • Updated OpenTelemetry core component version(s) to 1.20.1.
    (#​7990)

  See CHANGELOG for details.

• NuGet: OpenTelemetry.Exporter.Prometheus.HttpListener v1.20.1-beta.1

  • Fixed scrape responses being handed to the server in a single write, which
    on Linux and macOS made the listener allocate and hold a full copy of the
    response for each client that did not read it until the request completed or
    timed out. Responses are now written in bounded slices.
    (#​7957)

  • Fixed scrape requests that announce a request body holding a thread pool
    thread after their response had been sent on Linux and macOS for as long as
    the client kept trickling in the body. The connection is now closed after
    responding to a request with a body instead of being kept alive.
    (#​7962)

  • Fixed startup scrapes permanently omitting target_info and configured
    resource constant labels from subsequent scrape responses.
    (#​7984)

  • Updated OpenTelemetry core component version(s) to 1.20.1.
    (#​7990)

  See CHANGELOG for details.

• NuGet: OpenTelemetry.Shims.OpenTracing v1.20.1-beta.1

  • Updated OpenTelemetry core component version(s) to 1.20.1.
    (#​7990)

  See CHANGELOG for details.

1.20.0

For highlights and announcements pertaining to this release see: Release Notes > 1.20.0.

The following changes are from the previous release 1.19.1.

• NuGet: OpenTelemetry v1.20.0

  • Fixed SuppressInstrumentationScope reference counts leaking between inherited asynchronous execution contexts.
    (#​7803)

  • Self-diagnostic features are explicitly disabled on browser-based platforms (e.g. Blazor) and are now non-functional. Previously, attempting to enable self-diagnostics on such platforms would result in an exception at runtime.
    (#​7799)

  • Added TracerProviderBuilder.ConfigureSampler which receives the resolved Sampler whether set programmatically, via OTEL_TRACES_SAMPLER, or by default, and returns a replacement. Intended for library authors who need to influence sampling without overriding a sampler the application has configured.
    (#​7780)

  • Fixed ResourceBuilder.CreateDefault ignoring OTEL_RESOURCE_ATTRIBUTES and OTEL_SERVICE_NAME environment variables when the host IConfiguration does not contain those settings.
    (#​7855)

  • Added improved self-diagnostics logging to improve the support experience. The new SelfDiagnosticsOptions class configures a rolling file sink and a console sink through the standard options pipeline. Sinks are off by default.
    (#​7588)

  • Fixed a race that could incorrectly route a concurrent metric measurement to the overflow point when its tag set was published as the cardinality limit was reached.
    (#​7804)

  • Added OpenTelemetryLoggerOptions.Version and OpenTelemetryLoggerOptions.SchemaUrl options to set an instrumentation library version and schema URL applied to logs emitted via the Microsoft.Extensions.Logging ILogger integration.
    (#​7727)

  • Fixed LogRecord.CategoryName resetting the current Logger's Version to null when set to a new value.
    (#​7727)

  • Bounded the internal cache of Logger scopes keyed by instrumentation to avoid unbounded growth.
    (#​7727)

  • Fixed the MeterProvider and its IServiceProvider being kept alive after the host is disposed when using Microsoft.Extensions.Diagnostics versions prior to 9.0, which never dispose their MetricsSubscriptionManager (and its underlying MeterListener).
    (#​7924)

  • Fixed a race condition between recording a measurement and collecting a histogram with delta temporality that could cause an empty data point (with a count of zero) to be exported in the next collection cycle.
    (#​7923)

  • Improved metric collection performance after metric streams are removed by compacting metric storage during collection.
    (#​7945)

  See CHANGELOG for details.

• NuGet: OpenTelemetry.Api v1.20.0

  • Added Logger.SchemaUrl and a LoggerProvider.GetLogger overload accepting a schema URL parameter using the new LoggerOptions type.
    (#​7727)

  • Breaking change (pre-release only versions): LoggerProvider's protected TryCreateLogger(string? name, out Logger? logger) extensibility method has been replaced by TryCreateLogger(LoggerOptions options, out Logger? logger). Custom LoggerProvider subclasses that override the previous overload must update to override the new one; the old overload is no longer called.

1.20.0-beta.1

The following changes are from the previous release 1.19.1-beta.1.

• NuGet: OpenTelemetry.Exporter.Prometheus.AspNetCore v1.20.0-beta.1

  • A scrape request whose connection is aborted, or whose X-Prometheus-Scrape-Timeout-Seconds deadline elapses, now stops waiting for an in-progress metrics collection instead of continuing to wait for it to finish. The collection itself is not cancelled and continues running in the background.
    (#​7856)

  • Updated OpenTelemetry core component version(s) to 1.20.0.
    (#​7950)

  See CHANGELOG for details.
