Changelog

This file contains individual changes for the OpenTelemetry.Exporter.Zipkin package. For highlights and announcements covering all components see: Release Notes.

Unreleased

1.15.0

Released 2026-Jan-21

  • This package is deprecated and it will stop receiving any updates in December 2026. Zipkin already supports OTLP ingestion. Change your exporter to OpenTelemetry.Exporter.OpenTelemetryProtocol as stated in the Deprecating Zipkin Exporter blog post. (#6750)

1.14.0

Released 2025-Nov-12

  • Breaking Change NuGet packages now use the Sigstore bundle format (.sigstore.json) for digital signatures instead of separate signature (.sig) and certificate (.pem) files. This requires cosign 3.0 or later for verification. See the Digital signing section for updated verification instructions. (#6623)

1.14.0-rc.1

Released 2025-Oct-21

  • Breaking Change When targeting net8.0, the package now depends on version 8.0.0 of the Microsoft.Extensions.DependencyInjection.Abstractions, Microsoft.Extensions.Diagnostics.Abstractions and Microsoft.Extensions.Logging.Configuration NuGet packages. (#6327)

  • Add support for .NET 10.0. (#6307)

1.13.1

Released 2025-Oct-09

1.13.0

Released 2025-Oct-01

  • Removed the peer service resolver, which was based on earlier experimental semantic conventions that are not part of the stable specification. This change ensures that the exporter no longer modifies or assumes the value of peer service attributes. (#6191)

  • Extended remote endpoint calculation to align with the opentelemetry-specification. (#6191)

1.12.0

Released 2025-Apr-29

Released 2022-Aug-02

1.3.0

Released 2022-Jun-03

1.3.0-rc.2

Released 2022-June-1

  • Improve the conversion and formatting of attribute values. The list of data types that must be supported per the OpenTelemetry specification is more narrow than what the .NET OpenTelemetry SDK supports. Numeric built-in value types are supported by converting to a long or double as appropriate except for numeric types that could cause overflow (ulong) or rounding (decimal) which are converted to strings. Non-numeric built-in types - string, char, bool are supported. All other types are converted to a string. Array values are also supported. (#3281)
  • Fix conversion of array-valued resource attributes. They were previously converted to a string like "System.String[]". (#3281)
  • Fix exporting of array-valued attributes on an Activity. Previously, each item in the array would result in a new tag on an exported Activity. Now, array-valued attributes are serialized to a JSON-array representation. (#3281)

1.3.0-beta.2

Released 2022-May-16

  • Removes net5.0 target and replaced with net6.0 as .NET 5.0 is going out of support. The package keeps netstandard2.0 target, so it can still be used with .NET5.0 apps. (#3147)

1.3.0-beta.1

Released 2022-Apr-15

  • Removes .NET Framework 4.6.1. The minimum .NET Framework version supported is .NET 4.6.2. (#3190)

1.2.0

Released 2022-Apr-15

1.2.0-rc5

Released 2022-Apr-12

1.2.0-rc4

Released 2022-Mar-30

  • Added support for Activity Status and StatusDescription which were added to Activity from System.Diagnostics.DiagnosticSource version 6.0. Prior to version 6.0, setting the status of an Activity was provided by the .NET OpenTelemetry API via the Activity.SetStatus extension method in the OpenTelemetry.Trace namespace. Internally, this extension method added the status as tags on the Activity: otel.status_code and otel.status_description. Therefore, to maintain backward compatibility, the exporter falls back to using these tags to infer status. (#3003)

1.2.0-rc3

Released 2022-Mar-04

  • Modified Export method to catch all exceptions. (#2935)

1.2.0-rc2

(#2219)

1.2.0-alpha2

Released 2021-Aug-24

  • Enabling endpoint configuration in ZipkinExporterOptions via OTEL_EXPORTER_ZIPKIN_ENDPOINT environment variable. (#1453)

1.0.0-rc2

Released 2021-Jan-29

  • Changed ZipkinExporter class and constructor from internal to public. (#1612)

  • Zipkin will now set the error tag to the Status.Description value or an empty string when Status.StatusCode (otel.status_code tag) is set to ERROR. (#1579 #1620 #1655)

  • Zipkin will no longer send the otel.status_code tag if the value is UNSET. (#1609 #1620)

  • Zipkin bool tag values will now be sent as true/false instead of True/False. (#1609)
