v4.1.1

• #160 - run tests on .NET Framework (@alsi-lawr)
• #163 - parse OTEL_* header and resource attribute values according to spec (@nblumhardt)

v4.1.0

• #150 - provide a hook to call OpenTelemetry.SuppressInstrumentationScope.Begin() when required (@nblumhardt)
• #152 - support reading OTEL_* configuration variables from sources other than the environment (@srogovtsev)

v4.0.0

• #141 - breaking - recognize core OTEL_OTLP_EXPORTER_* variables (@AlbertoMonteiro)
• #145 - add GitHub issue templates (@nblumhardt)
• #146 - breaking - recognize OTEL_SERVICE_NAME (@nblumhardt)
• #147 - breaking - map events carrying SpanStartTimestamp as OTLP spans (@nblumhardt)
• #149 - README updates (@nblumhardt)

Breaking changes

• Sink behavior may change in the presence of OTEL_* environment variables. To prevent this, pass ignoreEnvironment: true to any of the WriteTo configuration methods.
• Log events carrying a SpanStartTimestamp property of type DateTime will now be recognized as spans rather than logs.

v3.0.0

• #136 - breaking - use Serilog 4's batching implementation, drop Serilog.Sinks.PeriodicBatching dependency (@nblumhardt)
• #139 - align TFMs with Serilog 4, adding net8.0 and net471 (@nblumhardt)

v2.0.0

• #113 - breaking - use SourceContext to populate instrumentation scope name (@nblumhardt)
• #118 - documentation for suppressing instrumentation (@nblumhardt)
• #122 - update Serilog.Sinks.PeriodicBatching dependency (@nblumhardt)
• #123 - add headers and resourceAttributes to simple configuration methods (@nblumhardt)
• #131 - add restrictedToMinimumLevel parameter to configuration methods (@CloudeaSoft)
• #125 - specify a non-tracing default HttpMessageHandler on .NET 6.0+ (@KodrAus)
• #133 - add includedData parameter to configuration methods (@binginsin)

#113 defaults to mapping SourceContext to the instrumentation scope name, and will omit the SourceContext from the log event payload by default. To preserve it, specify IncludedData.SourceContextAttribute.

v1.2.0

• #110 - use Serilog 3.1's LogEvent.TraceId and LogEvent.SpanId instead of the ConditionalWeakTable workaround (@nblumhardt)
• #111 - preserve DateTime/DateTimeOffset's full 100 nanosecond precision when converting to Unix nanos (@nblumhardt)

v1.1.0

• #104 - IncludedData.TemplateBody option, using the raw message template text instead of the rendered message as the log record body (@danelson)
• #106 - IncludedData.MessageTemplateRenderingsAttribute option, include pre-rendered strings for any message template parameters with custom format specifiers (@nblumhardt)

v1.0.2

• #98 - update NUPKG dependencies, avoiding a vulnerable version of Grpc.Client (@nblumhardt)

v1.0.1

• #91 - include README in package for display on nuget.org (@nblumhardt)
• #90 - line up package description with README text
• #92 - don't include prerelease suffix in non-prerelease telemetry_sdk.version attribute values (@nblumhardt)

v1.0.0

Features in 1.0.0

• Full support for the OTLP Logs protocol with gRPC and HTTP/protobuf transport flavors
• Full support for structured log events including complex property types
• Follows standard semantic conventions for service naming, exception information, etc.
• Configuration of additional resource attributes
• Configuration of outbound HTTP request handling and attached headers
• Batched/asynchronous WriteTo support
• Synchronous/hard-failing AuditTo support
• Trace and span correlation through System.Diagnostics.Activity
