### Added
- The `IsEmpty` method is added to the `Instrument` type in
`go.opentelemetry.io/otel/sdk/metric`.
This method is used to check if an `Instrument` instance is a
zero-value. (#5431)
- Store and provide the emitted `context.Context` in `ScopeRecords` of
`go.opentelemetry.io/otel/sdk/log/logtest`. (#5468)
- The `go.opentelemetry.io/otel/semconv/v1.26.0` package.
The package contains semantic conventions from the `v1.26.0` version of
the OpenTelemetry Semantic Conventions. (#5476)
- The `AssertRecordEqual` method to
`go.opentelemetry.io/otel/log/logtest` to allow comparison of two log
records in tests. (#5499)
- The `WithHeaders` option to
`go.opentelemetry.io/otel/exporters/zipkin` to allow configuring custom
http headers while exporting spans. (#5530)
### Changed
- `Tracer.Start` in `go.opentelemetry.io/otel/trace/noop` no longer
allocates a span for empty span context. (#5457)
- Upgrade `go.opentelemetry.io/otel/semconv/v1.25.0` to
`go.opentelemetry.io/otel/semconv/v1.26.0` in
`go.opentelemetry.io/otel/example/otel-collector`. (#5490)
- Upgrade `go.opentelemetry.io/otel/semconv/v1.25.0` to
`go.opentelemetry.io/otel/semconv/v1.26.0` in
`go.opentelemetry.io/otel/example/zipkin`. (#5490)
- Upgrade `go.opentelemetry.io/otel/semconv/v1.25.0` to
`go.opentelemetry.io/otel/semconv/v1.26.0` in
`go.opentelemetry.io/otel/exporters/zipkin`. (#5490)
- The exporter no longer exports the deprecated "otel.library.name" or
"otel.library.version" attributes.
- Upgrade `go.opentelemetry.io/otel/semconv/v1.25.0` to
`go.opentelemetry.io/otel/semconv/v1.26.0` in
`go.opentelemetry.io/otel/sdk/resource`. (#5490)
- Upgrade `go.opentelemetry.io/otel/semconv/v1.25.0` to
`go.opentelemetry.io/otel/semconv/v1.26.0` in
`go.opentelemetry.io/otel/sdk/trace`. (#5490)
- `SimpleProcessor.OnEmit` in `go.opentelemetry.io/otel/sdk/log` no
longer allocates a slice which makes it possible to have a
zero-allocation log processing using `SimpleProcessor`. (#5493)
- Use non-generic functions in the `Start` method of
`"go.opentelemetry.io/otel/sdk/trace".Trace` to reduce memory
allocation. (#5497)
- `service.instance.id` is populated for a `Resource` created with
`"go.opentelemetry.io/otel/sdk/resource".Default` with a default value
when `OTEL_GO_X_RESOURCE` is set. (#5520)
- Improve performance of metric instruments in
`go.opentelemetry.io/otel/sdk/metric` by removing unnecessary calls to
`time.Now`. (#5545)
### Fixed
- Log a warning to the OpenTelemetry internal logger when a `Record` in
`go.opentelemetry.io/otel/sdk/log` drops an attribute due to a limit
being reached. (#5376)
- Identify the `Tracer` returned from the global `TracerProvider` in
`go.opentelemetry.io/otel/global` with its schema URL. (#5426)
- Identify the `Meter` returned from the global `MeterProvider` in
`go.opentelemetry.io/otel/global` with its schema URL. (#5426)
- Log a warning to the OpenTelemetry internal logger when a `Span` in
`go.opentelemetry.io/otel/sdk/trace` drops an attribute, event, or link
due to a limit being reached. (#5434)
- Document instrument name requirements in
`go.opentelemetry.io/otel/metric`. (#5435)
- Prevent random number generation data-race for experimental rand
exemplars in `go.opentelemetry.io/otel/sdk/metric`. (#5456)
- Fix counting number of dropped attributes of `Record` in
`go.opentelemetry.io/otel/sdk/log`. (#5464)
- Fix panic in baggage creation when a member contains `0x80` char in
key or value. (#5494)
- Correct comments for the priority of the `WithEndpoint` and
`WithEndpointURL` options and their corresponding environment variables
in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`.
(#5508)
- Retry trace and span ID generation if it generated an invalid one in
`go.opentelemetry.io/otel/sdk/trace`. (#5514)
- Fix stale timestamps reported by the last-value aggregation. (#5517)
- Indicate the `Exporter` in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp` must be
created by the `New` method. (#5521)
- Improved performance in all `{Bool,Int64,Float64,String}SliceValue`
functions of `go.opentelemetry.io/attributes` by reducing the number of
allocations. (#5549)
As discussed in a previous SIG meeting, this PR adds support for setting
a default value for
[`service.instance.id`](https://github.com/open-telemetry/semantic-conventions/tree/main/docs/resource#service-experimental)
according to semantic conventions:
> Implementations, such as SDKs, are recommended to generate a random
Version 1 or Version 4 [RFC 4122](https://www.ietf.org/rfc/rfc4122.txt)
UUID, but are free to use an inherent unique ID as the source of this
value if stability is desirable. In that case, the ID SHOULD be used as
source of a UUID Version 5 and SHOULD use the following UUID as the
namespace: `4d63009a-8d0f-11ee-aad7-4c796ed8e320`.
This PR follows the recommendation and populates `service.instance.id`
with a random Version 4 UUID. The functionality is guarded by the
`OTEL_GO_X_RESOURCE` feature flag environment variable.
There are plans to declare `service.instance.id` stable and also make it
a required attribute (similar to `service.name`). Once this happens, the
functionality can be made available regardless of whether
`OTEL_GO_X_RESOURCE` is set.

Fix#5455
The `math/rand.Rand` type is not safe for concurrent access. Concurrent
measurements, and therefore concurrent exemplar computation, are
allowed. Ensure this concurrent design does not lead to data races with
`rng`.
From
https://github.com/open-telemetry/opentelemetry-go-contrib/pull/5654#discussion_r1617971674
Constructing a view requires an `Instrument` to be constructed. Given
`NewView` will not return an error directly when an empty instrument is
passed, it may be ideal for users to check this prior to making the
call. Instead of having all use-cases copy this code, export it so they
can just call the method.
This release includes the first beta release of the OpenTelemetry Logs
Bridge API and SDK for Go.
### Added
- Add example for `go.opentelemetry.io/otel/exporters/stdout/stdoutlog`.
(#5242)
- Add `RecordFactory` in `go.opentelemetry.io/otel/sdk/log/logtest` to
facilitate testing exporter and processor implementations. (#5258)
- Add `RecordFactory` in `go.opentelemetry.io/otel/log/logtest` to
facilitate testing bridge implementations. (#5263)
- The count of dropped records from the `BatchProcessor` in
`go.opentelemetry.io/otel/sdk/log` is logged. (#5276)
- Add metrics in the `otel-collector` example. (#5283)
- Add the synchronous gauge instrument to
`go.opentelemetry.io/otel/metric`. (#5304)
- An `int64` or `float64` synchronous gauge instrument can now be
created from a `Meter`.
- All implementations of the API
(`go.opentelemetry.io/otel/metric/noop`,
`go.opentelemetry.io/otel/sdk/metric`) are updated to support this
instrument.
- Add logs to `go.opentelemetry.io/otel/example/dice`. (#5349)
### Changed
- The `Shutdown` method of `Exporter` in
`go.opentelemetry.io/otel/exporters/stdout/stdouttrace` ignores the
context cancellation and always returns `nil`. (#5189)
- The `ForceFlush` and `Shutdown` methods of the exporter returned by
`New` in `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric` ignore
the context cancellation and always return `nil`. (#5189)
- Apply the value length limits to `Record` attributes in
`go.opentelemetry.io/otel/sdk/log`. (#5230)
- De-duplicate map attributes added to a `Record` in
`go.opentelemetry.io/otel/sdk/log`. (#5230)
- `go.opentelemetry.io/otel/exporters/stdout/stdoutlog` won't print
timestamps when `WithoutTimestamps` option is set. (#5241)
- The `go.opentelemetry.io/otel/exporters/stdout/stdoutlog` exporter
won't print `AttributeValueLengthLimit` and `AttributeCountLimit` fields
now, instead it prints the `DroppedAttributes` field. (#5272)
- Improved performance in the `Stringer` implementation of
`go.opentelemetry.io/otel/baggage.Member` by reducing the number of
allocations. (#5286)
- Set the start time for last-value aggregates in
`go.opentelemetry.io/otel/sdk/metric`. (#5305)
- The `Span` in `go.opentelemetry.io/otel/sdk/trace` will record links
without span context if either non-empty `TraceState` or attributes are
provided. (#5315)
- Upgrade all dependencies of `go.opentelemetry.io/otel/semconv/v1.24.0`
to `go.opentelemetry.io/otel/semconv/v1.25.0`. (#5374)
### Fixed
- Comparison of unordered maps for
`go.opentelemetry.io/otel/log.KeyValue` and
`go.opentelemetry.io/otel/log.Value`. (#5306)
- Fix the empty output of `go.opentelemetry.io/otel/log.Value` in
`go.opentelemetry.io/otel/exporters/stdout/stdoutlog`. (#5311)
- Split the behavior of `Recorder` in
`go.opentelemetry.io/otel/log/logtest` so it behaves as a
`LoggerProvider` only. (#5365)
- Fix wrong package name of the error message when parsing endpoint URL
in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`.
(#5371)
- Identify the `Logger` returned from the global `LoggerProvider` in
`go.opentelemetry.io/otel/log/global` with its schema URL. (#5375)
#5304 introduced the following incompatible changes:
- `InstrumentKindObservableCounter`: value changed from 4 to 5
- `InstrumentKindObservableGauge`: value changed from 6 to 7
- `InstrumentKindObservableUpDownCounter`: value changed from 5 to 6
This reverts that change, making `InstrumentKindGauge` explicitly `7`.
Additionally, this removes the use of `iota` to prevent this kind of
breaking change from being accidentally introduced in the future.
