Release Notes

open-telemetry/opentelemetry-rust (opentelemetry)

v0.31.0

Compare Source

Released 2025-Sep-25

• Breaking Change return type of opentelemetry::global::set_tracer_provider to Unit to align with metrics counterpart
• Add get_all method to opentelemetry::propagation::Extractor to return all values of the given propagation key and provide a default implementation.
• Add an IntoIterator implementation for opentelemetry::trace::TraceState to allow iterating through its key-value pair collection.

v0.30.0

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.

v0.28.0

Compare Source

Released 2025-Feb-10

• Bump msrv to 1.75.0.
• Breaking opentelemetry::global::shutdown_tracer_provider() Removed from this crate, should now use tracer_provider.shutdown() see #​2369 for a migration example.
• Breaking Removed unused opentelemetry::PropagationError struct.

v0.27.1

Compare Source

Released 2024-Nov-27

v0.27.0

Compare Source

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

Compare Source

• 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.
1715
shows the exact changes needed to make this migration. If you are starting new,
refer to the
examples
to learn how to provide Observable callbacks.

v0.24.0

Compare Source

• 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.

v0.23.0

Compare Source

Added

• #​1640 Add PropagationError
• #​1701 Gauge no longer requires otel-unstable feature flag, as OpenTelemetry specification for Gauge instrument is stable.

Removed

• Remove urlencoding crate dependency. #​1613
• Remove global providers for Logs $1691
  LoggerProviders are not meant for end users to get loggers from. It is only required for the log bridges.
  Below global constructs for the logs are removed from API:
  - opentelemetry::global::logger
  - opentelemetry::global::set_logger_provider
  - opentelemetry::global::shutdown_logger_provider
  - opentelemetry::global::logger_provider
  - opentelemetry::global::GlobalLoggerProvider
  - opentelemetry::global::ObjectSafeLoggerProvider
  For creating appenders using Logging bridge API, refer to the opentelemetry-tracing-appender example

Changed

• BREAKING Moving LogRecord implementation to the SDK. 1702.

  • Relocated LogRecord struct to SDK.
  • Introduced the LogRecord trait in the API for populating log records. This trait is implemented by the SDK.
    This is the breaking change for the authors of Log Appenders. Refer to the opentelemetry-appender-tracing for more details.

• Deprecate versioned_logger() in favor of logger_builder() 1567.

Before:

let logger = provider.versioned_logger(
    "my-logger-name",
    Some(env!("CARGO_PKG_VERSION")),
    Some("https://opentelemetry.io/schemas/1.0.0"),
    Some(vec![KeyValue::new("key", "value")]),
);

After:

let logger = provider
    .logger_builder("my-logger-name")
    .with_version(env!("CARGO_PKG_VERSION"))
    .with_schema_url("https://opentelemetry.io/schemas/1.0.0")
    .with_attributes(vec![KeyValue::new("key", "value")])
    .build();

• Deprecate versioned_tracer() in favor of tracer_builder() 1567.

Before:

let tracer = provider.versioned_tracer(
    "my-tracer-name",
    Some(env!("CARGO_PKG_VERSION")),
    Some("https://opentelemetry.io/schemas/1.0.0"),
    Some(vec![KeyValue::new("key", "value")]),
);

After:

let tracer = provider
    .tracer_builder("my-tracer-name")
    .with_version(env!("CARGO_PKG_VERSION"))
    .with_schema_url("https://opentelemetry.io/schemas/1.0.0")
    .with_attributes(vec![KeyValue::new("key", "value")])
    .build();

v0.22.0

Compare Source

Added

• #​1410 Add experimental synchronous gauge. This is behind the feature flag, and can be enabled by enabling the feature otel_unstable for opentelemetry crate.

• #​1410 Guidelines to add new unstable/experimental features.

Changed

• Modified AnyValue.Map to be backed by HashMap instead of custom OrderMap,
  which internally used IndexMap. There was no requirement to maintain the order
  of entries, so moving from IndexMap to HashMap offers slight performance
  gains, and avoids IndexMap dependency. This affects body and attributes of
  LogRecord.
  #​1353
• Add TextMapCompositePropagator #​1373
• Turned off events for NoopLogger to save on operations
  #​1455

Removed

• Removed OrderMap type as there was no requirement to use this over regular
  HashMap.
  #​1353
• Remove API for Creating Histograms with signed integers. #​1371
• Remove global::shutdown_meter_provider, use SdkMeterProvider::shutdown
  directly instead #​1412.

v0.21.0

Compare Source

This release should been seen as 1.0-rc4 following 1.0-rc3 in v0.20.0. Refer to CHANGELOG.md in individual creates for details on changes made in different creates.

Changed

• Bump MSRV to 1.65 #​1318
• Bump MSRV to 1.64 #​1203
• opentelemetry crate now only carries the API types #​1186. Use the opentelemetry_sdk crate for the SDK types.
• trace::noop::NoopSpan no longer implements Default and instead exposes
  a const DEFAULT value. #​1270
• Updated crate documentation and examples.
  #​1256
• Breaking SpanBuilder attributes changed from OrderMap<Key, Value> to
  Vec<KeyValue> and with_attributes_map method is removed from SpanBuilder.
  This implies that OpenTelemetry API will no longer perform
  de-dup of attribute Keys.
  #​1293.
