 ## [Unreleased]
 
+## [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.
+  Use `go.opentelemetry.io/otel` instead. (#4039)
+
+## [1.15.1/0.38.1] 2023-05-02
+
+### Fixed
+
+- Remove unused imports from `sdk/resource/host_id_bsd.go` which caused build failures. (#4040, #4041)
+
