## [Unreleased]
## [1.20.0/0.43.0] 2023-11-10
This release brings a breaking change for custom trace API implementations. Some interfaces (`TracerProvider`, `Tracer`, `Span`) now embed the `go.opentelemetry.io/otel/trace/embedded` types. Implementors need to update their implementations based on what they want the default behavior to be. See the "API Implementations" section of the [trace API] package documentation for more information about how to accomplish this.
### Added
- Add `go.opentelemetry.io/otel/bridge/opencensus.InstallTraceBridge`, which installs the OpenCensus trace bridge, and replaces `opencensus.NewTracer`. (#4567)
- Add scope version to trace and metric bridges in `go.opentelemetry.io/otel/bridge/opencensus`. (#4584)
- Add the `go.opentelemetry.io/otel/trace/embedded` package to be embedded in the exported trace API interfaces. (#4620)
- Add the `go.opentelemetry.io/otel/trace/noop` package as a default no-op implementation of the trace API. (#4620)
- Add context propagation in `go.opentelemetry.io/otel/example/dice`. (#4644)
- Add view configuration to `go.opentelemetry.io/otel/example/prometheus`. (#4649)
- Add `go.opentelemetry.io/otel/metric.WithExplicitBucketBoundaries`, which allows defining default explicit bucket boundaries when creating histogram instruments. (#4603)
- Add `Version` function in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`. (#4660)
- Add `Version` function in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`. (#4660)
- Add Summary, SummaryDataPoint, and QuantileValue to `go.opentelemetry.io/sdk/metric/metricdata`. (#4622)
- `go.opentelemetry.io/otel/bridge/opencensus.NewMetricProducer` now supports exemplars from OpenCensus. (#4585)
- Add support for `WithExplicitBucketBoundaries` in `go.opentelemetry.io/otel/sdk/metric`. (#4605)
- Add support for Summary metrics in `go.opentelemetry.io/otel/bridge/opencensus`. (#4668)
### Deprecated
- Deprecate `go.opentelemetry.io/otel/bridge/opencensus.NewTracer` in favor of `opencensus.InstallTraceBridge`. (#4567)
- Deprecate `go.opentelemetry.io/otel/example/fib` package is in favor of `go.opentelemetry.io/otel/example/dice`. (#4618)
- Deprecate `go.opentelemetry.io/otel/trace.NewNoopTracerProvider`.
Use the added `NewTracerProvider` function in `go.opentelemetry.io/otel/trace/noop` instead. (#4620)
- Deprecate `go.opentelemetry.io/otel/example/view` package in favor of `go.opentelemetry.io/otel/example/prometheus`. (#4649)
- Deprecate `go.opentelemetry.io/otel/exporters/otlp/otlpmetric`. (#4693)
### Changed
- `go.opentelemetry.io/otel/bridge/opencensus.NewMetricProducer` returns a `*MetricProducer` struct instead of the metric.Producer interface. (#4583)
- The `TracerProvider` in `go.opentelemetry.io/otel/trace` now embeds the `go.opentelemetry.io/otel/trace/embedded.TracerProvider` type.
This extends the `TracerProvider` interface and is is a breaking change for any existing implementation.

- The function `New` in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc` returns `*Exporter` instead of `"go.opentelemetry.io/otel/sdk/metric".Exporter`. (#4272)
- The function `New` in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp` returns `*Exporter` instead of `"go.opentelemetry.io/otel/sdk/metric".Exporter`. (#4272)
- If an attribute set is omitted from an async callback, the previous value will no longer be exported in `go.opentelemetry.io/otel/sdk/metric`. (#4290)
- If an attribute set is observed multiple times in an async callback in `go.opentelemetry.io/otel/sdk/metric`, the values will be summed instead of the last observation winning. (#4289)
- Allow the explicit bucket histogram aggregation to be used for the up-down counter, observable counter, observable up-down counter, and observable gauge in the `go.opentelemetry.io/otel/sdk/metric` package. (#4332)
- Restrict `Meter`s in `go.opentelemetry.io/otel/sdk/metric` to only register and collect instruments it created. (#4333)

- Upgrade all use of `go.opentelemetry.io/otel/semconv` to use `v1.21.0`. (#4408)
- Increase instrument name maximum length from 63 to 255 characters in `go.opentelemetry.io/otel/sdk/metric`. (#4434)
- Add `go.opentelemetry.op/otel/sdk/metric.WithProducer` as an `Option` for `"go.opentelemetry.io/otel/sdk/metric".NewManualReader` and `"go.opentelemetry.io/otel/sdk/metric".NewPeriodicReader`. (#4346)
### Removed
- Remove `Reader.RegisterProducer` in `go.opentelemetry.io/otel/metric`.
Use the added `WithProducer` option instead. (#4346)
- Remove `Reader.ForceFlush` in `go.opentelemetry.io/otel/metric`.

- OTLP metrics exporter now supports the Exponential Histogram Data Type. (#4222)
- Fix serialization of `time.Time` zero values in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc` and `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp` packages. (#4271)
### Changed
- Use `strings.Cut()` instead of `string.SplitN()` for better readability and memory use. (#4049)
- `MeterProvider` returns noop meters once it has been shutdown. (#4154)
### Removed
- The deprecated `go.opentelemetry.io/otel/metric/instrument` package is removed.
Use `go.opentelemetry.io/otel/metric` instead. (#4055)
### Fixed
- Fix build for BSD based systems in `go.opentelemetry.io/otel/sdk/resource`. (#4077)
## [1.16.0-rc.1/0.39.0-rc.1] 2023-05-03
This is a release candidate for the v1.16.0/v0.39.0 release.
That release is expected to include the `v1` release of the OpenTelemetry Go metric API and will provide stability guarantees of that API.
See our [versioning policy](VERSIONING.md) for more information about these stability guarantees.
### Added
- Support global `MeterProvider` in `go.opentelemetry.io/otel`. (#4039)
- Use `Meter` for a `metric.Meter` from the global `metric.MeterProvider`.
- Use `GetMeterProivder` for a global `metric.MeterProvider`.
- Use `SetMeterProivder` to set the global `metric.MeterProvider`.
### Changed
- Move the `go.opentelemetry.io/otel/metric` module to the `stable-v1` module set.
This stages the metric API to be released as a stable module. (#4038)
### Removed
- The `go.opentelemetry.io/otel/metric/global` package is removed.

## Documentation
Each non-example Go Module should have its own `README.md` containing:
Each (non-internal, non-test) package must be documented using
[Go Doc Comments](https://go.dev/doc/comment),
preferably in a `doc.go` file.
- A pkg.go.dev badge which can be generated [here](https://pkg.go.dev/badge/).
- Brief description.
- Installation instructions (and requirements if applicable).
- Hyperlink to an example. Depending on the component the example can be:
- An `example_test.go` like [here](exporters/stdout/stdouttrace/example_test.go).
- A sample Go application with its own `README.md`, like [here](example/zipkin).
- Additional documentation sections such us:
- Configuration,
- Contributing,
- References.
Prefer using [Examples](https://pkg.go.dev/testing#hdr-Examples)
instead of putting code snippets in Go doc comments.
In some cases, you can even create [Testable Examples](https://go.dev/blog/examples).
[Here](exporters/jaeger/README.md) is an example of a concise `README.md`.
You can install and run a "local Go Doc site" in the following way:
Moreover, it should be possible to navigate to any `README.md` from the
root `README.md`.
```sh
go install golang.org/x/pkgsite/cmd/pkgsite@latest
pkgsite
```
[`go.opentelemetry.io/otel/metric`](https://pkg.go.dev/go.opentelemetry.io/otel/metric)

> Warning: methods may be added to this interface in minor releases.
These interfaces are defined by the OpenTelemetry specification and will be
updated as the specification evolves.
Otherwise, stable interfaces MUST NOT be modified.
#### How to Change Specification Interfaces
When an API change must be made, we will update the SDK with the new method one
release before the API change. This will allow the SDK one version before the
API change to work seamlessly with the new API.
If an incompatible version of the SDK is used with the new API the application
will fail to compile.
#### How Not to Change Specification Interfaces
We have explored using a v2 of the API to change interfaces and found that there
was no way to introduce a v2 and have it work seamlessly with the v1 of the API.
Problems happened with libraries that upgraded to v2 when an application did not,
and would not produce any telemetry.
More detail of the approaches considered and their limitations can be found in
the [Use a V2 API to evolve interfaces](https://github.com/open-telemetry/opentelemetry-go/issues/3920)

### Testing
The tests should never leak goroutines.
Use the term `ConcurrentSafe` in the test name when it aims to verify the
absence of race conditions.
### Internal packages
The use of internal packages should be scoped to a single module. A sub-module
should never import from a parent internal package. This creates a coupling
between the two modules where a user can upgrade the parent without the child
and if the internal package API has changed it will fail to upgrade[^3].
There are two known exceptions to this rule:
- `go.opentelemetry.io/otel/internal/global`
- This package manages global state for all of opentelemetry-go. It needs to
be a single package in order to ensure the uniqueness of the global state.
- `go.opentelemetry.io/otel/internal/baggage`
- This package provides values in a `context.Context` that need to be
recognized by `go.opentelemetry.io/otel/baggage` and
`go.opentelemetry.io/otel/bridge/opentracing` but remain private.
If you have duplicate code in multiple modules, make that code into a Go
template stored in `go.opentelemetry.io/otel/internal/shared` and use [gotmpl]
to render the templates in the desired locations. See [#4404] for an example of
this.

## Semantic Convention Generation
New versions of the [OpenTelemetry specification] mean new versions of the `semconv` package need to be generated.
New versions of the [OpenTelemetry Semantic Conventions] mean new versions of the `semconv` package need to be generated.
The `semconv-generate` make target is used for this.
1. Checkout a local copy of the [OpenTelemetry specification] to the desired release tag.
1. Checkout a local copy of the [OpenTelemetry Semantic Conventions] to the desired release tag.
2. Pull the latest `otel/semconvgen` image: `docker pull otel/semconvgen:latest`
3. Run the `make semconv-generate ...` target from this repository.
For example,
```sh
export TAG="v1.13.0" # Change to the release version you are generating.
export OTEL_SPEC_REPO="/absolute/path/to/opentelemetry-specification"
git -C "$OTEL_SPEC_REPO" checkout "tags/$TAG" -b "$TAG"
export TAG="v1.21.0" # Change to the release version you are generating.
export OTEL_SEMCONV_REPO="/absolute/path/to/opentelemetry/semantic-conventions"
docker pull otel/semconvgen:latest
make semconv-generate # Uses the exported TAG and OTEL_SPEC_REPO.
make semconv-generate # Uses the exported TAG and OTEL_SEMCONV_REPO.
```
This should create a new sub-package of [`semconv`](./semconv).
Ensure things look correct before submitting a pull request to include the addition.
**Note**, the generation code was changed to generate versions >= 1.13.
To generate versions prior to this, checkout the old release of this repository (i.e. [2fe8861](https://github.com/open-telemetry/opentelemetry-go/commit/2fe8861a24e20088c065b116089862caf9e3cd8b)).
## Breaking changes validation
You can run `make gorelease` that runs [gorelease](https://pkg.go.dev/golang.org/x/exp/cmd/gorelease) to ensure that there are no unwanted changes done in the public API.
You can check/report problems with `gorelease` [here](https://golang.org/issues/26420).

# Measurements
Measurements are made by recording values and information about the values with
an instrument. How these measurements are recorded depends on the instrument.
Measurements for synchronous instruments ([Int64Counter], [Int64UpDownCounter],
[Int64Histogram], [Float64Counter], [Float64UpDownCounter], and
[Float64Histogram]) are recorded using the instrument methods directly. All
counter instruments have an Add method that is used to measure an increment
value, and all histogram instruments have a Record method to measure a data
point.
Asynchronous instruments ([Int64ObservableCounter],
[Int64ObservableUpDownCounter], [Int64ObservableGauge],
[Float64ObservableCounter], [Float64ObservableUpDownCounter], and
[Float64ObservableGauge]) record measurements within a callback function. The
callback is registered with the Meter which ensures the callback is called once
per collection cycle. A callback can be registered two ways: during the
instrument's creation using an option, or later using the RegisterCallback
method of the [Meter] that created the instrument.
If the following criteria are met, an option ([WithInt64Callback] or
[WithFloat64Callback]) can be used during the asynchronous instrument's
creation to register a callback ([Int64Callback] or [Float64Callback],
respectively):
- The measurement process is known when the instrument is created
- Only that instrument will make a measurement within the callback
- The callback never needs to be unregistered
If the criteria are not met, use the RegisterCallback method of the [Meter] that
created the instrument to register a [Callback].

# API Implementations
This package does not conform to the standard Go versioning policy; all of its
interfaces may have methods added to them without a package major version bump.
This non-standard API evolution could surprise an uninformed implementation
author. They could unknowingly build their implementation in a way that would
result in a runtime panic for their users that update to the new API.
The API is designed to help inform an instrumentation author about this
non-standard API evolution. It requires them to choose a default behavior for
unimplemented interface methods. There are three behavior choices they can
make:
- Compilation failure
- Panic
- Default to another implementation
All interfaces in this API embed a corresponding interface from
[go.opentelemetry.io/otel/trace/embedded]. If an author wants the default
behavior of their implementations to be a compilation failure, signaling to
their users they need to update to the latest version of that implementation,
they need to embed the corresponding interface from
[go.opentelemetry.io/otel/trace/embedded] in their implementation. For
example,
import "go.opentelemetry.io/otel/trace/embedded"
type TracerProvider struct {
embedded.TracerProvider
// ...
}
If an author wants the default behavior of their implementations to panic, they
can embed the API interface directly.
import "go.opentelemetry.io/otel/trace"
type TracerProvider struct {
trace.TracerProvider
// ...
}
This option is not recommended. It will lead to publishing packages that
contain runtime panics when users update to newer versions of
[go.opentelemetry.io/otel/trace], which may be done with a trasitive
dependency.
Finally, an author can embed another implementation in theirs. The embedded
implementation will be used for methods not defined by the author. For example,
an author who wants to default to silently dropping the call can use
[go.opentelemetry.io/otel/trace/noop]:
import "go.opentelemetry.io/otel/trace/noop"
type TracerProvider struct {
noop.TracerProvider
// ...
}
It is strongly recommended that authors only embed
[go.opentelemetry.io/otel/trace/noop] if they choose this default behavior.
That implementation is the only one OpenTelemetry authors can guarantee will
fully implement all the API interfaces when a user updates their API.
