+# uuid
+The uuid package generates and inspects UUIDs based on
+[RFC 4122](https://datatracker.ietf.org/doc/html/rfc4122)
+and DCE 1.1: Authentication and Security Services. 
+
+This package is based on the github.com/pborman/uuid package (previously named
+code.google.com/p/go-uuid).  It differs from these earlier packages in that
+a UUID is a 16 byte array rather than a byte slice.  One loss due to this
+change is the ability to represent an invalid UUID (vs a NIL UUID).

+
+### Added
+

+## [1.24.0/0.46.0/0.0.1-alpha] 2024-02-23
+
+This release is the last to support [Go 1.20].

+
+### Fixed
+

+
+## [1.23.0] 2024-02-06
+
+This release contains the first stable, `v1`, release of the following modules:
+
+- `go.opentelemetry.io/otel/bridge/opencensus`
+- `go.opentelemetry.io/otel/bridge/opencensus/test`
+- `go.opentelemetry.io/otel/example/opencensus`
+- `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`
+- `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`
+- `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric`
+
+See our [versioning policy](VERSIONING.md) for more information about these stability guarantees.
+
+### Added
+
+- Add `WithEndpointURL` option to the `exporters/otlp/otlpmetric/otlpmetricgrpc`, `exporters/otlp/otlpmetric/otlpmetrichttp`, `exporters/otlp/otlptrace/otlptracegrpc` and `exporters/otlp/otlptrace/otlptracehttp` packages. (#4808)
+- Experimental exemplar exporting is added to the metric SDK.
+  See [metric documentation](./sdk/metric/internal/x/README.md#exemplars) for more information about this feature and how to enable it. (#4871)
+- `ErrSchemaURLConflict` is added to `go.opentelemetry.io/otel/sdk/resource`.
+  This error is returned when a merge of two `Resource`s with different (non-empty) schema URL is attempted. (#4876)
+
+### Changed
+
+- The `Merge` and `New` functions in `go.opentelemetry.io/otel/sdk/resource` now returns a partial result if there is a schema URL merge conflict.
+  Instead of returning `nil` when two `Resource`s with different (non-empty) schema URLs are merged the merged `Resource`, along with the new `ErrSchemaURLConflict` error, is returned.
+  It is up to the user to decide if they want to use the returned `Resource` or not.
+  It may have desired attributes overwritten or include stale semantic conventions. (#4876)
+
+### Fixed
+
+- Fix `ContainerID` resource detection on systemd when cgroup path has a colon. (#4449)
+- Fix `go.opentelemetry.io/otel/sdk/metric` to cache instruments to avoid leaking memory when the same instrument is created multiple times. (#4820)
+- Fix missing `Mix` and `Max` values for `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric` by introducing `MarshalText` and `MarshalJSON` for the `Extrema` type in `go.opentelemetry.io/sdk/metric/metricdata`. (#4827)
+
+## [1.23.0-rc.1] 2024-01-18
+
+This is a release candidate for the v1.23.0 release.
+That release is expected to include the `v1` release of the following modules:
+
+- `go.opentelemetry.io/otel/bridge/opencensus`
+- `go.opentelemetry.io/otel/bridge/opencensus/test`
+- `go.opentelemetry.io/otel/example/opencensus`

+- Add `NewMemberRaw` and `NewKeyValuePropertyRaw` in `go.opentelemetry.io/otel/baggage`. (#4804)
+
+### Changed
+
+- Upgrade all use of `go.opentelemetry.io/otel/semconv` to use `v1.24.0`. (#4754)
+- Update transformations in `go.opentelemetry.io/otel/exporters/zipkin` to follow `v1.24.0` version of the OpenTelemetry specification. (#4754)
+- Record synchronous measurements when the passed context is canceled instead of dropping in `go.opentelemetry.io/otel/sdk/metric`.
+  If you do not want to make a measurement when the context is cancelled, you need to handle it yourself (e.g  `if ctx.Err() != nil`). (#4671)

+- Fix whitespace encoding of `Member.String` in `go.opentelemetry.io/otel/baggage`. (#4756)
+- Fix observable not registered error when the asynchronous instrument has a drop aggregation in `go.opentelemetry.io/otel/sdk/metric`. (#4772)
+- Fix baggage item key so that it is not canonicalized in `go.opentelemetry.io/otel/bridge/opentracing`. (#4776)
+- Fix `go.opentelemetry.io/otel/bridge/opentracing` to properly handle baggage values that requires escaping during propagation. (#4804)
+- Fix a bug where using multiple readers resulted in incorrect asynchronous counter values in `go.opentelemetry.io/otel/sdk/metric`. (#4742)

See the "API Implementations" section of the [trace API] package documentation for more information about how to accomplish this.

+### Ignoring context cancellation
+
+OpenTelemetry API implementations need to ignore the cancellation of the context that are
+passed when recording a value (e.g. starting a span, recording a measurement, emitting a log).
+Recording methods should not return an error describing the cancellation state of the context
+when they complete, nor should they abort any work.
+
+This rule may not apply if the OpenTelemetry specification defines a timeout mechanism for
+the method. In that case the context cancellation can be used for the timeout with the
+restriction that this behavior is documented for the method. Otherwise, timeouts
+are expected to be handled by the user calling the API, not the implementation.
+
+Stoppage of the telemetry pipeline is handled by calling the appropriate `Shutdown` method
+of a provider. It is assumed the context passed from a user is not used for this purpose.
+
+Outside of the direct recording of telemetry from the API (e.g. exporting telemetry,
+force flushing telemetry, shutting down a signal provider) the context cancellation
+should be honored. This means all work done on behalf of the user provided context
+should be canceled.
