Release Notes

open-telemetry/opentelemetry-dotnet (OpenTelemetry.Exporter.OpenTelemetryProtocol)

`v1.18.0`

Release details: 1.18.0

Breaking change: The maximum size of a single OTLP export request is now
64 MiB by default instead of 128 MiB to conform with the OpenTelemetry specification.
Raise the value of the new OtlpExporterOptions.MaxRequestSizeBytes property
to increase the capacity.
Added OtlpExporterOptions.MaxRequestSizeBytes to configure the maximum OTLP
request size limit, as required by the OpenTelemetry specification. The default
is the recommended 64 MiB. A batch whose serialized payload exceeds the limit
is not sent and is dropped in its entirety. The maximum supported value is
256 MiB.
Added OtlpExporterOptions.MaxResponseSizeBytes to configure the maximum size
of a response the exporter will accept, as required by the OpenTelemetry
specification. The default is the recommended 4 MiB. A response exceeding the
limit is discarded and treated as a non-retryable failure.
Added the otel.sdk.processor.log.processed and otel.sdk.processor.span.processed
SDK self-observability metrics.
Added support for serializing attribute values that are key/value lists in
the OTLP, console and Zipkin exporters.
The OTLP exporter will now export the logger version, if it was specified.
Add new ITelemetryHostInitializer interface for applications that do not
support hosted services, such as Blazor, to use to manually initialize the
OpenTelemetry SDK as part of application startup.
BatchActivityExportProcessor and SimpleActivityExportProcessor no longer
forward spans to the exporter once Shutdown has been called, and
BatchActivityExportProcessor.Shutdown now waits for in-flight OnEnd calls
to finish enqueueing before flushing.
Fixed self-diagnostics log lines being silently dropped when an event message
was too long to fit in the internal buffer. Such content is now truncated.
Fixed activity creation throwing when multiple tracer providers returned a
sampler attribute with the same key.
Fixed logger, meter and tracer providers leaking background threads if an
exception is thrown by their constructor after resource creation.
Avoid formatting exceptions and creating exception attributes when
RecordException is called on a span that is not recorded.
Fixed UseOtlpExporter to respect options configured with
services.Configure<OtlpExporterOptions>(...).
Clamped the server-supplied OTLP/gRPC retry delay (RetryInfo.retry_delay) to
a minimum value of 100 milliseconds.
Fixed serialization failures leaving failed trace, metric, and log batches in
the serializer's per-thread state.
Fixed the persistent-storage retry thread terminating permanently on an
unexpected exception.
Fixed the OTLP exporter from retrying certain non-transient HTTP failures.
Improved OTLP log attribute serialization performance by avoiding unnecessary
boxing.
Improved OTLP histogram serialization performance by avoiding a redundant
scan of explicit bucket bounds.
Fixed persistent storage allowing a blob write to exceed the configured
maximum storage size.
Improved OTLP/gRPC response status handling performance by avoiding unnecessary
header enumeration on .NET 8+.
Fixed the Zipkin exporter to read responses with HttpCompletionOption.ResponseHeadersRead
for the .NET Framework and .NET Standard targets.
Fixed inefficient parsing of the Jaeger uber-trace-id header when targeting
net462 or netstandard2.0.

`v1.17.0`

Release details: 1.17.0

Added support for a Schema URL on Resource instances.
The Resource Schema URL is now printed alongside the resource attributes
when using the Console and OTLP exporters.
Added ExcludedTagKeys property to MetricStreamConfiguration to support
excluding specific tag keys from metric streams.
Updated tracestate key validation to comply with the W3C Trace Context
Level 2 grammar.
The SDK now depends on Microsoft.Extensions.Configuration.EnvironmentVariables
instead of using a vendored implementation.
All libraries are now marked as trim and AOT compatible.
Fixed a metric storage leak that occurred when meters and instruments were
repeatedly created and disposed.
Fixed TraceContextPropagator to normalize empty tracestate header values
to null when extracting trace context.
Fixed OtlpLogExporter so OtlpExporterOptions.ExportProcessorType and
OtlpExporterOptions.BatchExportProcessorOptions are respected when
LogRecordExportProcessorOptions are not configured.
Fixed the OTLP exporter dropping retryable data instead of saving it to disk
when persistent storage retry is enabled and an export exceeds the configured
timeout.
Fixed the OTLP/HTTP exporter silently dropping data when an export timed out.
Fixed the OTLP/gRPC exporter logging incorrectly when an export timed out.
Performance and memory improvements for the OTLP exporter when exporting logs
and metrics.

`v1.16.0`

Release details: 1.16.0

Breaking Change Explicit histogram boundaries no longer allow more than
10 million values.
Fix BaggagePropagator to correctly follow Key and Value Encoding rules.
Add support for the W3C randomness flag.
Fixed TraceContextPropagator to deduplicate duplicate tracestate keys.
ObservedTimestamp will now be exported for logs in the console exporter.
Fixed NullReferenceException when exporting OTLP logs if the scope key is
null.
Added opt-in support for gzip compression to the OTLP exporter.
Fixed OTLP disk retry data being stored incorrectly when using persistent
storage retry.
Fixed OtlpLogExporter integration with IHttpClientFactory.
Do not enable the OTLP integration with IHttpClientFactory when mTLS is
enabled.
Handle Retry-After response headers that specify a date instead of a delay.
observed_time_unix_nano will no longer always be identical to time_unix_nano
when using the logs bridge API.
Stop validating View-provided metric stream Name against the instrument name
syntax.
Fix incorrect validation of OTEL_BSP_* and OTEL_BLRP_* environment variables.
Fix observable instrument callbacks running once per reader instead of once per
collection cycle.
Added exception safety for user-supplied ExemplarReservoir implementations.
Fixed a circular reference which could cause a LoggerProvider to fail to
resolve when one of its dependencies depends on ILogger or ILoggerFactory.

`v1.15.3`

Release details: 1.15.3

Breaking change: Fixed tracestate parsing to reject keys that do not
begin with a lowercase letter, including keys beginning with digits, to
align with the W3C Trace Context specification.
Breaking change: Fixed an insecure disk retry default for OTLP export.
Disk retry now requires OTEL_DOTNET_EXPERIMENTAL_OTLP_DISK_RETRY_DIRECTORY_PATH
when OTEL_DOTNET_EXPERIMENTAL_OTLP_RETRY=disk is configured.
Improve efficiency of parsing of baggage and B3 propagation headers.
OtlpLogExporter now uses IHttpClientFactory on .NET 8+.
Fixed an issue in OTLP/gRPC retry handling when parsing gRPC statuses.
Fixed OTEL_SPAN_ATTRIBUTE_VALUE_LENGTH_LIMIT not being applied.
Fixed baggage and trace headers not respecting the maximum length in some cases.
Fixed BaggagePropagator to trim optional whitespace (OWS) around =
separators when parsing the baggage header.
Fixed BaggagePropagator to strip baggage properties from values when
parsing the baggage header.
Fixed OTLP persistent storage clean-up handling for malformed filenames.
Fixed resource leak in batch and periodic exporting task workers for Blazor/WASM.
Fixed LogRecord.LogLevel to preserve LogLevel.None.
Fixed OTEL_TRACES_SAMPLER_ARG handling for out-of-range values.
Fixed an issue with OTLP disk retry storage where metrics and logs used the
traces storage directory.
Fixed full OTLP endpoint being logged by internal diagnostics.
Improve efficiency of parsing of baggage, B3 and Jaeger propagation headers.
Hardened Zipkin exporter memory usage for endpoint caching and array tag
serialization.

`v1.15.2`

Release details: 1.15.2

Limit how much of the response body is read by the OTLP exporter when
export fails and error logging is enabled.
Added Task-based worker support for BatchExportProcessor and
PeriodicExportingMetricReader to enable the OpenTelemetry SDK to work
in single-threaded WebAssembly environments such as Blazor and
Uno Platform.
