## [Unreleased]
## [1.19.0/0.42.0/0.0.7] 2023-09-28
This release contains the first stable release of the OpenTelemetry Go [metric SDK].
Our project stability guarantees now apply to the `go.opentelemetry.io/otel/sdk/metric` package.
See our [versioning policy](VERSIONING.md) for more information about these stability guarantees.
### Added
- Add the "Roll the dice" getting started application example in `go.opentelemetry.io/otel/example/dice`. (#4539)
- The `WithWriter` and `WithPrettyPrint` options to `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric` to set a custom `io.Writer`, and allow displaying the output in human-readable JSON. (#4507)
### Changed
- Allow '/' characters in metric instrument names. (#4501)
- The exporter in `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric` does not prettify its output by default anymore. (#4507)
- Upgrade `gopkg.io/yaml` from `v2` to `v3` in `go.opentelemetry.io/otel/schema`. (#4535)
### Fixed
- In `go.opentelemetry.op/otel/exporters/prometheus`, don't try to create the Prometheus metric on every `Collect` if we know the scope is invalid. (#4499)
### Removed
- Remove `"go.opentelemetry.io/otel/bridge/opencensus".NewMetricExporter`, which is replaced by `NewMetricProducer`. (#4566)
## [1.19.0-rc.1/0.42.0-rc.1] 2023-09-14
This is a release candidate for the v1.19.0/v0.42.0 release.
That release is expected to include the `v1` release of the OpenTelemetry Go metric SDK and will provide stability guarantees of that SDK.
See our [versioning policy](VERSIONING.md) for more information about these stability guarantees.
### Changed
- Allow '/' characters in metric instrument names. (#4501)

## [1.15.0-rc.1/0.38.0-rc.1] 2023-03-01
This is a release candidate for the v1.15.0/v0.38.0 release.
That release will 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.
This release drops the compatibility guarantee of [Go 1.18].
### Added
- Support global `MeterProvider` in `go.opentelemetry.io/otel`. (#3818)
- 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
- Dropped compatibility testing for [Go 1.18].
The project no longer guarantees support for this version of Go. (#3813)
### Fixed
- Handle empty environment variable as it they were not set. (#3764)
- Clarify the `httpconv` and `netconv` packages in `go.opentelemetry.io/otel/semconv/*` provide tracing semantic conventions. (#3823)
- Fix race conditions in `go.opentelemetry.io/otel/exporters/metric/prometheus` that could cause a panic. (#3899)
- Fix sending nil `scopeInfo` to metrics channel in `go.opentelemetry.io/otel/exporters/metric/prometheus` that could cause a panic in `github.com/prometheus/client_golang/prometheus`. (#3899)
### Deprecated
- The `go.opentelemetry.io/otel/metric/global` package is deprecated.
Use `go.opentelemetry.io/otel` instead. (#3818)
### Removed
- The deprecated `go.opentelemetry.io/otel/metric/unit` package is removed. (#3814)
