Released 2025-May-23

#​2821 Context
based suppression capabilities added: Added the ability to prevent recursive
telemetry generation through new context-based suppression mechanisms. This
feature helps prevent feedback loops and excessive telemetry when OpenTelemetry
components perform their own operations.

New methods added to Context:

• is_telemetry_suppressed() - Checks if telemetry is suppressed in this
  context
• with_telemetry_suppressed() - Creates a new context with telemetry
  suppression enabled
• is_current_telemetry_suppressed() - Efficiently checks if the current thread's context
  has telemetry suppressed
• enter_telemetry_suppressed_scope() - Convenience method to enter a scope where telemetry is
  suppressed

These methods allow SDK components, exporters, and processors to temporarily
disable telemetry generation during their internal operations, ensuring more
predictable and efficient observability pipelines.

• re-export tracing for internal-logs feature to remove the need of adding tracing as a dependency

v0.29.1

Compare Source

Release 2025-Apr-01

• Bug Fix: Re-export WithContext at opentelemetry::trace::context::WithContext #​2879 to restore backwards compatibility
  • The new path for WithContext and FutureExt are in opentelemetry::context as they are independent of the trace signal. Users should prefer this path.

v0.29.0

Compare Source

Released 2025-Mar-21

• Breaking Moved ExportError trait from opentelemetry::trace::ExportError to opentelemetry_sdk::export::ExportError
• Breaking Moved TraceError enum from opentelemetry::trace::TraceError to opentelemetry_sdk::trace::TraceError
• Breaking Moved TraceResult type alias from opentelemetry::trace::TraceResult to opentelemetry_sdk::trace::TraceResult
• Bug Fix: InstrumentationScope implementation for PartialEq and Hash fixed to include Attributes also.
• Breaking changes for baggage users: #​2717
  • Changed value type of Baggage from Value to StringValue
  • Updated Baggage constants to reflect latest standard (MAX_KEY_VALUE_PAIRS - 180 -> 64, MAX_BYTES_FOR_ONE_PAIR - removed) and increased insert performance see #2284.
  • Align Baggage.remove() signature with .get() to take the key as a reference
  • Baggage can't be retrieved from the Context directly anymore and needs to be accessed via context.baggage()
  • with_baggage() and current_with_baggage() override any existing Baggage in the Context
  • Baggage keys can't be empty and only allow ASCII visual chars, except "(),/:;<=>?@&#8203;[\]{} (see RFC7230, Section 3.2.6)
  • KeyValueMetadata does not publicly expose its fields. This should be transparent change to the users.
• Changed Context to use a stack to properly handle out of order dropping of ContextGuard. This imposes a limit of 65535 nested contexts on a single thread. See #2378 and #1887.
• Added additional name: Option<&str> parameter to the event_enabled method
  on the Logger trait. This allows implementations (SDK, processor, exporters)
  to leverage this additional information to determine if an event is enabled.

v0.29.0

Compare Source

Released 2025-Mar-21

• Update opentelemetry dependency version to 0.29

• Update opentelemetry_sdk dependency version to 0.29

• Update opentelemetry-http dependency version to 0.29

• Update opentelemetry-proto dependency version to 0.29

• The OTEL_EXPORTER_OTLP_TIMEOUT, OTEL_EXPORTER_OTLP_TRACES_TIMEOUT, OTEL_EXPORTER_OTLP_METRICS_TIMEOUT and OTEL_EXPORTER_OTLP_LOGS_TIMEOUT are changed from seconds to milliseconds.

• Fixed .with_headers() in HttpExporterBuilder to correctly support multiple key/value pairs. #​2699

• Fixed
  #​2770
  partially to properly handle shutdown() when using http. (tonic still
  does not do proper shutdown)

• Breaking
  ExporterBuilder's build() method now Result with ExporterBuildError being the
  Error variant. Previously it returned signal specific errors like LogError
  from the opentelemetry_sdk, which are no longer part of the sdk. No changes
  required if you were using unwrap/expect. If you were matching on the returning
  Error enum, replace with the enum ExporterBuildError. Unlike the previous
  Error which contained many variants unrelated to building an exporter, the
  new one returns specific variants applicable to building an exporter. Some
  variants might be applicable only on select features.
  Also, now unused Error enum is removed.

• Breaking ExportConfig's timeout field is now optional(Option<Duration>)

• Breaking Export configuration done via code is final. ENV variables cannot be used to override the code config.
  Do not use code based config, if there is desire to control the settings via ENV variables.
  List of ENV variables and corresponding setting being affected by this change.

  • OTEL_EXPORTER_OTLP_ENDPOINT -> ExportConfig.endpoint
  • OTEL_EXPORTER_OTLP_TIMEOUT -> ExportConfig.timeout

open-telemetry/opentelemetry-rust (opentelemetry_sdk)

v0.31.0

Compare Source

Released 2025-Sep-25

• Updated opentelemetry and opentelemetry-http dependencies to version 0.31.0.

• Feature: Add span flags support for isRemote property in OTLP exporter (#​3153)

• Updated span and link transformations to properly set flags field (0x100 for local, 0x300 for remote)

• TODO: Placeholder for Span processor related things

  • Fix SpanProcessor::on_start is no longer called on non recording spans

• Fix: Restore true parallel exports in the async-native BatchSpanProcessor by honoring OTEL_BSP_MAX_CONCURRENT_EXPORTS (#​2959). A regression in #​2685 inadvertently awaited the export() future directly in opentelemetry-sdk/src/trace/span_processor_with_async_runtime.rs instead of spawning it on the runtime, forcing all exports to run sequentially.

• Feature: Added Clone implementation to SdkLogger for API consistency with SdkTracer (#​3058).

• Fix: batch size accounting in BatchSpanProcessor when queue is full (#​3089).

• Fix: Resolved dependency issue where the "logs" feature incorrectly
  required the "trace" feature flag
  (#​3096).
  The logs functionality now operates independently, while automatic correlation
  between logs and traces continues to work when the "trace" feature is
  explicitly enabled.

v0.30.0

Compare Source

Released 2025-May-23

• Updated opentelemetry and opentelemetry-http dependencies to version 0.30.0.

• It is now possible to add links to a Span via the SpanRef that you get from
  a Context. 2959

• Feature: Added context based telemetry suppression. #​2868

  • SdkLogger, SdkTracer modified to respect telemetry suppression based on
    Context. In other words, if the current context has telemetry suppression
    enabled, then logs/spans will be ignored.
  • The flag is typically set by OTel
    components to prevent telemetry from itself being fed back into OTel.
  • BatchLogProcessor, BatchSpanProcessor, and PeriodicReader modified to set
    the suppression flag in their dedicated thread, so that telemetry generated from
    those threads will not be fed back into OTel.
  • Similarly, SimpleLogProcessor
    also modified to suppress telemetry before invoking exporters.

• Feature: Implemented and enabled cardinality capping for Metrics by
  default. #​2901

  • The default cardinality limit is 2000 and can be customized using Views.
  • This feature was previously removed in version 0.28 due to the lack of
    configurability but has now been reintroduced with the ability to configure
    the limit.
  • Fixed the overflow attribute to correctly use the boolean value true
    instead of the string "true".
    #​2878

• The shutdown_with_timeout method is added to SpanProcessor, SpanExporter trait and TracerProvider.

• The shutdown_with_timeout method is added to LogExporter trait.

• The shutdown_with_timeout method is added to LogProvider and LogProcessor trait.

• Breaking MetricError, MetricResult no longer public (except when
  spec_unstable_metrics_views feature flag is enabled). OTelSdkResult should
  be used instead, wherever applicable. #​2906

• Breaking change, affecting custom MetricReader authors:

  • The
    shutdown_with_timeout method is added to MetricReader trait.
  • collect
    method on MetricReader modified to return OTelSdkResult.
    #​2905
  • MetricReader
    trait, ManualReader struct, Pipeline struct, InstrumentKind enum moved
    behind feature flag "experimental_metrics_custom_reader".
    #​2928

• Views improvements:

  • Core view functionality is now available by default—users can change the
    name, unit, description, and cardinality limit of a metric via views without
    enabling the spec_unstable_metrics_views feature flag. Advanced view
    features, such as custom aggregation or attribute filtering, still require
    the spec_unstable_metrics_views feature.
  • Removed new_view() method and View trait. Views can now be added by passing
    a function with signature Fn(&Instrument) -> Option<Stream> to the with_view
    method on MeterProviderBuilder.

• Introduced a builder pattern for Stream creation to use with views:

  • Added StreamBuilder struct with methods to configure stream properties
  • Added Stream::builder() method that returns a new StreamBuilder
  • StreamBuilder::build() returns Result<Stream, Box<dyn Error>> enabling
    proper validation.

Example of using views to rename a metric:

let view_rename = |i: &Instrument| {
    if i.name() == "my_histogram" {
        Some(
            Stream::builder()
                .with_name("my_histogram_renamed")
                .build()
                .unwrap(),
        )
    } else {
        None
    }
};

let provider = SdkMeterProvider::builder()
    // add exporters, set resource etc.
    .with_view(view_rename)
    .build();

• Breaking Aggregation enum moved behind feature flag
  "spec_unstable_metrics_views". This was only required when using advanced view
  capabilities.
  #​2928
• Breaking change, affecting custom PushMetricExporter authors:
  • The export method on PushMetricExporter now accepts &ResourceMetrics
    instead of &mut ResourceMetrics.
  • ResourceMetrics no longer exposes scope_metrics field, but instead
    offers scope_metrics() method that returns an iterator over the same.
  • ScopeMetrics no longer exposes metrics field, but instead offers
    metrics() method that returns an iterator over the same.
  • Sum, Gauge, Histogram & ExponentialHistogram no longer exposes
    data_points field, but instead offers data_points() method that returns
    an iterator over the same.
  • SumDataPoint, GaugeDataPoint, HistogramDataPoint &
    ExponentialHistogramDataPoint no longer exposes attributes, exemplars
    field, but instead offers attributes(), and exemplars() method that
    returns an iterator over the same.
  • Exemplar no longer exposes filtered_attributes field, but instead
    offers filtered_attributes() method that returns an iterator over
    the same.
  • HistogramDataPoint no longer exposes bounds and bucket_counts, but
    instead offers bounds() and bucket_counts() methods that returns an
    iterator over the same.
  • Metric no longer exposes name, description, unit, data fields, but
    instead offers name(), description(), unit(), and data() accessor methods.
  • ResourceMetrics no longer exposes resource field, but instead offers
    a resource() accessor method.
  • ScopeMetrics no longer exposes scope field, but instead offers
    a scope() accessor method.

v0.29.0

Compare Source

Released 2025-Mar-21

• Update opentelemetry dependency to 0.29.
• Update opentelemetry-http dependency to 0.29.
• Breaking: The Runtime trait has been simplified and refined. See the #​2641
  for the changes.
• Removed async-std support for Runtime, as async-std crate is deprecated.
• Calls to MeterProviderBuilder::with_resource, TracerProviderBuilder::with_resource,
  LoggerProviderBuilder::with_resource are now additive (#​2677).
• Moved ExportError trait from opentelemetry::trace::ExportError to opentelemetry_sdk::export::ExportError
• Moved TraceError enum from opentelemetry::trace::TraceError to opentelemetry_sdk::trace::TraceError
• Moved TraceResult type alias from opentelemetry::trace::TraceResult to opentelemetry_sdk::trace::TraceResult
• Breaking: Make force_flush() in PushMetricExporter synchronous
• Breaking: Updated the SpanExporter trait method signature:

  fn export(&mut self, batch: Vec<SpanData>) -> BoxFuture<'static, OTelSdkResult>;

to

  fn export(
    &mut self,
    batch: Vec<SpanData>,
) -> impl std::future::Future<Output = OTelSdkResult> + Send;

This affects anyone who writes custom exporters, as custom implementations of SpanExporter
should now define export as an async fn:

  impl trace::SpanExporter for CustomExporter {
    async fn export(&mut self, batch: Vec<trace::SpanData>) -> OTelSdkResult {
        // Implementation here
    }
}

• Breaking The SpanExporter::export() method no longer requires a mutable reference to self.
  Before:

    async fn export(&mut self, batch: Vec<SpanData>) -> OTelSdkResult

  After:

    async fn export(&self, batch: Vec<SpanData>) -> OTelSdkResult

  Custom exporters will need to internally synchronize any mutable state, if applicable.

• Breaking The shutdown_with_timeout method is added to MetricExporter trait. This is breaking change for custom MetricExporter authors.

• Bug Fix: BatchLogProcessor now correctly calls shutdown on the exporter
  when its shutdown is invoked.

• Reduced some info level logs to debug

• Breaking for custom LogProcessor/Exporter authors: Changed name
  parameter from &str to Option<&str> in event_enabled method on the
  LogProcessor and LogExporter traits. SdkLogger no longer passes its
  scope name but instead passes the incoming name when invoking
  event_enabled on processors.

• Breaking for custom LogExporter authors: shutdown() method in
  LogExporter trait no longer requires a mutable ref to self. If the exporter
  needs to mutate state, it should rely on interior mutability.
  2764

• Breaking (Affects custom Exporter/Processor authors only) Removed
  opentelemetry_sdk::logs::error::{LogError, LogResult}. These were not
  intended to be public. If you are authoring custom processor/exporters, use
  opentelemetry_sdk::error::OTelSdkError and
  opentelemetry_sdk::error::OTelSdkResult.
  2790

• Breaking for custom LogProcessor authors: Changed set_resource
  to require mutable ref.
  fn set_resource(&mut self, _resource: &Resource) {}

• Breaking: InMemoryExporter's return type change.

  • TraceResult<Vec<SpanData>> to Result<Vec<SpanData>, InMemoryExporterError>
  • MetricResult<Vec<ResourceMetrics>> to Result<Vec<ResourceMetrics>, InMemoryExporterError>
  • LogResult<Vec<LogDataWithResource>> to Result<Vec<LogDataWithResource>, InMemoryExporterError>
