Release Notes

open-telemetry/opentelemetry-rust (opentelemetry)

v0.30.0

Compare Source

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

Release 2025-Apr-01

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

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.

Released 2024-Nov-11

• Bump MSRV to 1.70 #​2179
• Add LogRecord::set_trace_context; an optional method conditional on the trace feature for setting trace context on a log record.
• Removed unnecessary public methods named as_any from AsyncInstrument trait and the implementing instruments: ObservableCounter, ObservableGauge, and ObservableUpDownCounter #​2187
• Introduced SyncInstrument trait to replace the individual synchronous instrument traits (SyncCounter, SyncGauge, SyncHistogram, SyncUpDownCounter) which are meant for SDK implementation. #​2207
• Ensured that observe method on asynchronous instruments can only be called inside a callback. This was done by removing the implementation of AsyncInstrument trait for each of the asynchronous instruments. #​2210
• Removed PartialOrd and Ord implementations for KeyValue. #​2215
• Breaking change for exporter authors: Marked KeyValue related structs and enums as non_exhaustive. #​2228
• Breaking change for log exporter authors: Marked AnyValue enum as non_exhaustive. #​2230
• Breaking change for Metrics users: The init method used to create instruments has been renamed to build. Also, try_init() method is removed from instrument builders. The return types of InstrumentProvider trait methods modified to return the instrument struct, instead of Result. #​2227

Before:

let counter = meter.u64_counter("my_counter").init();

Now:

let counter = meter.u64_counter("my_counter").build();

• Breaking change: #​2220

  • Removed deprecated method InstrumentationLibrary::new
  • Renamed InstrumentationLibrary to InstrumentationScope
  • Renamed InstrumentationLibraryBuilder to InstrumentationScopeBuilder
  • Removed deprecated methods LoggerProvider::versioned_logger and TracerProvider::versioned_tracer
  • Removed methods LoggerProvider::logger_builder, TracerProvider::tracer_builder and MeterProvider::versioned_meter
  • Replaced these methods with LoggerProvider::logger_with_scope, TracerProvider::logger_with_scope, MeterProvider::meter_with_scope
  • Replaced global::meter_with_version with global::meter_with_scope
  • Added global::tracer_with_scope
  • Refer to PR description for migration guide.

• Breaking change: replaced InstrumentationScope public attributes by getters #​2275

• Breaking change: #​2260

  • Removed global::set_error_handler and global::handle_error.
  • global::handle_error usage inside the opentelemetry crates has been replaced with global::otel_info, otel_warn, otel_debug and otel_error macros based on the severity of the internal logs.
  • The default behavior of global::handle_error was to log the error using eprintln!. With otel macros, the internal logs get emitted via tracing macros of matching severity. Users now need to configure a tracing layer/subscriber to capture these logs.
  • Refer to PR description for migration guide. Also refer to self-diagnostics example to learn how to view internal logs in stdout using tracing::fmt layer.

• Breaking change for exporter/processor authors: #​2266

  • Moved ExportError trait from opentelemetry::ExportError to opentelemetry_sdk::export::ExportError
  • Created new trait opentelemetry::trace::ExportError for trace API. This would be eventually be consolidated with ExportError in the SDK.
  • Moved LogError enum from opentelemetry::logs::LogError to opentelemetry_sdk::logs::LogError
  • Moved LogResult type alias from opentelemetry::logs::LogResult to opentelemetry_sdk::logs::LogResult
  • Moved MetricError enum from opentelemetry::metrics::MetricError to opentelemetry_sdk::metrics::MetricError
  • Moved MetricResult type alias from opentelemetry::metrics::MetricResult to opentelemetry_sdk::metrics::MetricResult
    These changes shouldn't directly affect the users of OpenTelemetry crate, as these constructs are used in SDK and Exporters. If you are an author of an sdk component/plug-in, like an exporter etc. please use these types from sdk. Refer CHANGELOG.md for more details, under same version section.

• Breaking 2291 Rename logs_level_enabled flag to spec_unstable_logs_enabled. Please enable this updated flag if the feature is needed. This flag will be removed once the feature is stabilized in the specifications.

v0.26.0

Compare Source

Released 2024-Sep-30

• BREAKING Public API changes:

  • Removed: Key.bool(), Key.i64(), Key.f64(), Key.string(), Key.array() #​2090. These APIs were redundant as they didn't offer any additional functionality. The existing KeyValue::new() API covers all the scenarios offered by these APIs.

  • Removed: ObjectSafeMeterProvider and GlobalMeterProvider #​2112. These APIs were unnecessary and were mainly meant for internal use.

  • Modified: MeterProvider.meter() and MeterProvider.versioned_meter() argument types have been updated to &'static str instead of impl Into<Cow<'static, str>>> #​2112. These APIs were modified to enforce the Meter name, version, and schema_url to be &'static str.

  • Renamed: NoopMeterCore to NoopMeter

• Added with_boundaries API to allow users to provide custom bounds for Histogram instruments. #​2135

v0.25.0

• BREAKING #​1993 Box complex types in AnyValue enum
  Before:

#[derive(Debug, Clone, PartialEq)]
pub enum AnyValue {
    /// An integer value
    Int(i64),
    /// A double value
    Double(f64),
    /// A string value
    String(StringValue),
    /// A boolean value
    Boolean(bool),
    /// A byte array
    Bytes(Vec<u8>),
    /// An array of `Any` values
    ListAny(Vec<AnyValue>),
    /// A map of string keys to `Any` values, arbitrarily nested.
    Map(HashMap<Key, AnyValue>),
}

After:

#[derive(Debug, Clone, PartialEq)]
pub enum AnyValue {
    /// An integer value
    Int(i64),
    /// A double value
    Double(f64),
    /// A string value
    String(StringValue),
    /// A boolean value
    Boolean(bool),
    /// A byte array
    Bytes(Box<Vec<u8>>),
    /// An array of `Any` values
    ListAny(Box<Vec<AnyValue>>),
    /// A map of string keys to `Any` values, arbitrarily nested.
    Map(Box<HashMap<Key, AnyValue>>),
}

So the custom log appenders should box these types while adding them in message body, or
attribute values. Similarly, the custom exporters should dereference these complex type values
before serializing.

Breaking :
#​2015 Removed
the ability to register callbacks for Observable instruments on Meter directly.
If you were using meter.register_callback to provide the callback, provide
them using with_callback method, while creating the Observable instrument
itself.

• Add "metrics", "logs" to default features. With this, default feature list is
  "trace", "metrics" and "logs".

• When "metrics" feature is enabled, KeyValue implements PartialEq, Eq,
  PartialOrder, Order, Hash. This is meant to be used for metrics
  aggregation purposes only.

• Removed Unit struct for specifying Instrument units. Unit is treated as an
  opaque string. Migration: Replace .with_unit(Unit::new("myunit")) with
  .with_unit("myunit").

• 1869 Introduced the LogRecord::set_target() method in the log bridge API.
  This method allows appenders to set the target/component emitting the logs.

Released 2025-May-23

• Updated opentelemetry dependency to version 0.30.0.

v0.29.1

Released 2025-Mar-24

• Bump tracing-opentelemetry to 0.30

v0.29.0

Released 2025-Mar-21

Fixes 1682.
"spec_unstable_logs_enabled" feature now do not suppress logs for other layers.

The special treatment of the "message" field has been extended when recording
string values. With this change, when a log is emitted with a field named
"message" (and string value), its value is directly assigned to the LogRecord’s
body rather than being stored as an attribute named "message". This offers a
slight performance improvement over previous.

For example, the below will now produce LogRecord with the message value
populated as LogRecord's body:

error!(name: "my-event-name", target: "my-system", event_id = 20, user_name = "otel", user_email = "otel@opentelemetry.io", message = "This is an example message");

Previously, Body was only populated when the below style was used.

error!(name: "my-event-name", target: "my-system", event_id = 20, user_name = "otel", user_email = "otel@opentelemetry.io", "This is an example message");

This style, while slightly slower, should still be used when the value is not a
simple string, but require format arguments as in the below example.

error!(name: "my-event-name", target: "my-system", event_id = 20, user_name = "otel", user_email = "otel@opentelemetry.io", "This is an example message with format arguments {} and {}", "foo", "bar");

Fixes 2658
InstrumentationScope(Logger) used by the appender now uses an empty ("") named
Logger. Previously, a Logger with name and version of the crate was used.
Receivers (processors, exporters) are expected to use LogRecord.target() as
scope name. This is already done in OTLP Exporters, so this change should be
transparent to most users.

• Passes event name to the event_enabled method on the Logger. This allows
  implementations (SDK, processor, exporters) to leverage this additional
  information to determine if an event is enabled.

• u64, i128, u128 and usize values are stored as opentelemetry::logs::AnyValue::Int
  when conversion is feasible. Otherwise stored as
  opentelemetry::logs::AnyValue::String. This avoids unnecessary string
  allocation when values can be represented in their original types.

• Byte arrays are stored as opentelemetry::logs::AnyValue::Bytes instead
  of string.

• Error fields are reported using attribute named "exception.message". For
  example, the below will now report an attribute named "exception.message",
  instead of previously reporting the user provided attribute "error".
  error!(....error = &OTelSdkError::AlreadyShutdown as &dyn std::error::Error...)

• perf - small perf improvement by avoiding string allocation of target

• Update opentelemetry dependency version to 0.29.

  Error enum, replace with the enum ExporterBuildError. Unlike the previous
  Error which contained many variants unrelated to building an exporter, the

Compare Source

Changed

• Breaking Moved duplicated (and unrelated) attributes from opentelemetry_semantic_conventions::trace and opentelemetry_semantic_conventions::resource into opentelemetry_semantic_conventions::attribute (which now contains all semantic attributes). trace and resource now only contain references to attributes which fall under their respective category.

Added

• Created opentelemetry_semantic_conventions::metric to store metric semantic conventions.

• Breaking 2040 Simplified stdout exporter:
  • Now only supports writing to stdout, removing ability to send telemetry to other streams.
  • Output format improved for better human readability.

open-telemetry/opentelemetry-rust (opentelemetry_sdk)

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.
