Part of #5412
- Use the recommended package name for the instrumentation exemplified
in the repository.
- Use the recommended detection of a `TracerProvider` from passed
context.
### 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.

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)
