+// If that happens, even if we keep these functions they can be replaced with
+// the trivial safe code.
+
+// NOTE: The usual way of doing an unsafe string-to-[]byte conversion is:
 //
-// Both of these wrapper functions still incur function call overhead since they
-// will not be inlined. We could write Go/asm copies of Sum64 and Digest.Write

+//
+// Unfortunately, as of Go 1.15.3 the inliner's cost model assigns a high enough
+// weight to this sequence of expressions that any function that uses it will
+// not be inlined. Instead, the functions below use a different unsafe

+
+
+
+## [8.11.4](https://github.com/go-redis/redis/compare/v8.11.3...v8.11.4) (2021-10-04)
+
+
+### Features
+
+* add acl auth support for sentinels ([f66582f](https://github.com/go-redis/redis/commit/f66582f44f3dc3a4705a5260f982043fde4aa634))
+* add Cmd.{String,Int,Float,Bool}Slice helpers and an example ([5d3d293](https://github.com/go-redis/redis/commit/5d3d293cc9c60b90871e2420602001463708ce24))
+* add SetVal method for each command ([168981d](https://github.com/go-redis/redis/commit/168981da2d84ee9e07d15d3e74d738c162e264c4))
+
+
+
+## v8.11
+
+- Remove OpenTelemetry metrics.
+- Supports more redis commands and options.
+
+## v8.10
+
+- Removed extra OpenTelemetry spans from go-redis core. Now go-redis instrumentation only adds a
+  single span with a Redis command (instead of 4 spans). There are multiple reasons behind this
+  decision:
+
+  - Traces become smaller and less noisy.
+  - It may be costly to process those 3 extra spans for each query.
+  - go-redis no longer depends on OpenTelemetry.
+
+  Eventually we hope to replace the information that we no longer collect with OpenTelemetry
+  Metrics.
+
+## v8.9
+
+- Changed `PubSub.Channel` to only rely on `Ping` result. You can now use `WithChannelSize`,
+  `WithChannelHealthCheckInterval`, and `WithChannelSendTimeout` to override default settings.
+
+## v8.8
+
+- To make updating easier, extra modules now have the same version as go-redis does. That means that
+  you need to update your imports:
+
+```
+github.com/go-redis/redis/extra/redisotel -> github.com/go-redis/redis/extra/redisotel/v8
+github.com/go-redis/redis/extra/rediscensus -> github.com/go-redis/redis/extra/rediscensus/v8
+```
+
+## v8.5
+
+- [knadh](https://github.com/knadh) contributed long-awaited ability to scan Redis Hash into a
+  struct:
+
+```go
+err := rdb.HGetAll(ctx, "hash").Scan(&data)
+
+err := rdb.MGet(ctx, "key1", "key2").Scan(&data)
+```
+
+- Please check [redismock](https://github.com/go-redis/redismock) by
+  [monkey92t](https://github.com/monkey92t) if you are looking for mocking Redis Client.

 ## v8

- Documentation at https://redis.uptrace.dev/
-
 - All commands require `context.Context` as a first argument, e.g. `rdb.Ping(ctx)`. If you are not
  using `context.Context` yet, the simplest option is to define global package variable
  `var ctx = context.TODO()` and use it when `ctx` is required.

+
+The paths of redis-server bin file and redis config file are defined in `main_test.go`:
+
+```
+var (
+	redisServerBin, _  = filepath.Abs(filepath.Join("testdata", "redis", "src", "redis-server"))
+	redisServerConf, _ = filepath.Abs(filepath.Join("testdata", "redis", "redis.conf"))

+```
+
+For local testing, you can change the variables to refer to your local files, or create a soft link
+to the corresponding folder for redis-server and copy the config file to `testdata/redis/`:
+
+```
+ln -s /usr/bin/redis-server ./go-redis/testdata/redis/src
+cp ./go-redis/testdata/redis.conf ./go-redis/testdata/redis/
+```
+
+Lastly, run:

-## [Unreleased]
-
-## [0.13.0] - 2020-10-08
-
-### Added
-
- OTLP Metric exporter supports Histogram aggregation. (#1209)
- The `Code` struct from the `go.opentelemetry.io/otel/codes` package now supports JSON marshaling and unmarshaling as well as implements the `Stringer` interface. (#1214)
- A Baggage API to implement the OpenTelemetry specification. (#1217)
-
-### Changed
-
- Set default propagator to no-op propagator. (#1184)
- The `HTTPSupplier`, `HTTPExtractor`, `HTTPInjector`, and `HTTPPropagator` from the `go.opentelemetry.io/otel/api/propagation` package were replaced with unified `TextMapCarrier` and `TextMapPropagator` in the `go.opentelemetry.io/otel` package. (#1212)
- The `New` function from the `go.opentelemetry.io/otel/api/propagation` package was replaced with `NewCompositeTextMapPropagator` in the `go.opentelemetry.io/otel` package. (#1212)
- The status codes of the `go.opentelemetry.io/otel/codes` package have been updated to match the latest OpenTelemetry specification.
-   They now are `Unset`, `Error`, and `Ok`.
-   They no longer track the gRPC codes. (#1214)
- The `StatusCode` field of the `SpanData` struct in the `go.opentelemetry.io/otel/sdk/export/trace` package now uses the codes package from this package instead of the gRPC project. (#1214)
- Move the `go.opentelemetry.io/otel/api/baggage` package into `go.opentelemetry.io/otel/propagators`. (#1217)
-
-### Fixed
-
- Copies of data from arrays and slices passed to `go.opentelemetry.io/otel/label.ArrayValue()` are now used in the returned `Value` instead of using the mutable data itself. (#1226)
-
-### Removed
-
- The `ExtractHTTP` and `InjectHTTP` functions from the `go.opentelemetry.io/otel/api/propagation` package were removed. (#1212)
- The `Propagators` interface from the `go.opentelemetry.io/otel/api/propagation` package was removed to conform to the OpenTelemetry specification.
-   The explicit `TextMapPropagator` type can be used in its place as this is the `Propagator` type the specification defines. (#1212)
- The `SetAttribute` method of the `Span` from the `go.opentelemetry.io/otel/api/trace` package was removed given its redundancy with the `SetAttributes` method. (#1216)
- The internal implementation of Baggage storage is removed in favor of using the new Baggage API functionality. (#1217)
- Remove duplicate hostname key `HostHostNameKey` in Resource semantic conventions. (#1219)
- Nested array/slice support has been removed. (#1226)
-
-## [0.12.0] - 2020-09-24
-
-### Added
-
- A `SpanConfigure` function in `go.opentelemetry.io/otel/api/trace` to create a new `SpanConfig` from `SpanOption`s. (#1108)
- In the `go.opentelemetry.io/otel/api/trace` package, `NewTracerConfig` was added to construct new `TracerConfig`s.
-   This addition was made to conform with our project option conventions. (#1155)
- Instrumentation library information was added to the Zipkin exporter. (#1119)
- The `SpanProcessor` interface now has a `ForceFlush()` method. (#1166)
- More semantic conventions for k8s as resource attributes. (#1167)
-
-### Changed
-
- Add reconnecting udp connection type to Jaeger exporter.
-   This change adds a new optional implementation of the udp conn interface used to detect changes to an agent's host dns record.
-   It then adopts the new destination address to ensure the exporter doesn't get stuck. This change was ported from jaegertracing/jaeger-client-go#520. (#1063)
- Replace `StartOption` and `EndOption` in `go.opentelemetry.io/otel/api/trace` with `SpanOption`.
-   This change is matched by replacing the `StartConfig` and `EndConfig` with a unified `SpanConfig`. (#1108)
- Replace the `LinkedTo` span option in `go.opentelemetry.io/otel/api/trace` with `WithLinks`.
-   This is be more consistent with our other option patterns, i.e. passing the item to be configured directly instead of its component parts, and provides a cleaner function signature. (#1108)
- The `go.opentelemetry.io/otel/api/trace` `TracerOption` was changed to an interface to conform to project option conventions. (#1109)
- Move the `B3` and `TraceContext` from within the `go.opentelemetry.io/otel/api/trace` package to their own `go.opentelemetry.io/otel/propagators` package.
-    This removal of the propagators is reflective of the OpenTelemetry specification for these propagators as well as cleans up the `go.opentelemetry.io/otel/api/trace` API. (#1118)
- Rename Jaeger tags used for instrumentation library information to reflect changes in OpenTelemetry specification. (#1119)
- Rename `ProbabilitySampler` to `TraceIDRatioBased` and change semantics to ignore parent span sampling status. (#1115)
- Move `tools` package under `internal`. (#1141)
- Move `go.opentelemetry.io/otel/api/correlation` package to `go.opentelemetry.io/otel/api/baggage`. (#1142)
-   The `correlation.CorrelationContext` propagator has been renamed `baggage.Baggage`.  Other exported functions and types are unchanged.
- Rename `ParentOrElse` sampler to `ParentBased` and allow setting samplers depending on parent span. (#1153)
- In the `go.opentelemetry.io/otel/api/trace` package, `SpanConfigure` was renamed to `NewSpanConfig`. (#1155)
- Change `dependabot.yml` to add a `Skip Changelog` label to dependabot-sourced PRs. (#1161)
- The [configuration style guide](https://github.com/open-telemetry/opentelemetry-go/blob/master/CONTRIBUTING.md#config) has been updated to
-   recommend the use of `newConfig()` instead of `configure()`. (#1163)
- The `otlp.Config` type has been unexported and changed to `otlp.config`, along with its initializer. (#1163)
- Ensure exported interface types include parameter names and update the
-   Style Guide to reflect this styling rule. (#1172)
- Don't consider unset environment variable for resource detection to be an error. (#1170)
- Rename `go.opentelemetry.io/otel/api/metric.ConfigureInstrument` to `NewInstrumentConfig` and
-  `go.opentelemetry.io/otel/api/metric.ConfigureMeter` to `NewMeterConfig`.
- ValueObserver instruments use LastValue aggregator by default. (#1165)
- OTLP Metric exporter supports LastValue aggregation. (#1165)
- Move the `go.opentelemetry.io/otel/api/unit` package to `go.opentelemetry.io/otel/unit`. (#1185)
- Rename `Provider` to `MeterProvider` in the `go.opentelemetry.io/otel/api/metric` package. (#1190)
- Rename `NoopProvider` to `NoopMeterProvider` in the `go.opentelemetry.io/otel/api/metric` package. (#1190)
- Rename `NewProvider` to `NewMeterProvider` in the `go.opentelemetry.io/otel/api/metric/metrictest` package. (#1190)
- Rename `Provider` to `MeterProvider` in the `go.opentelemetry.io/otel/api/metric/registry` package. (#1190)
- Rename `NewProvider` to `NewMeterProvider` in the `go.opentelemetry.io/otel/api/metri/registryc` package. (#1190)

-## [0.11.0] - 2020-08-24
-
-### Added
-
- Support for exporting array-valued attributes via OTLP. (#992)
- `Noop` and `InMemory` `SpanBatcher` implementations to help with testing integrations. (#994)
- Support for filtering metric label sets. (#1047)
- A dimensionality-reducing metric Processor. (#1057)
- Integration tests for more OTel Collector Attribute types. (#1062)
- A new `WithSpanProcessor` `ProviderOption` is added to the `go.opentelemetry.io/otel/sdk/trace` package to create a `Provider` and automatically register the `SpanProcessor`. (#1078)
-
-### Changed
-
- Rename `sdk/metric/processor/test` to `sdk/metric/processor/processortest`. (#1049)
- Rename `sdk/metric/controller/test` to `sdk/metric/controller/controllertest`. (#1049)
- Rename `api/testharness` to `api/apitest`. (#1049)
- Rename `api/trace/testtrace` to `api/trace/tracetest`. (#1049)
- Change Metric Processor to merge multiple observations. (#1024)
- The `go.opentelemetry.io/otel/bridge/opentracing` bridge package has been made into its own module.
-   This removes the package dependencies of this bridge from the rest of the OpenTelemetry based project. (#1038)
- Renamed `go.opentelemetry.io/otel/api/standard` package to `go.opentelemetry.io/otel/semconv` to avoid the ambiguous and generic name `standard` and better describe the package as containing OpenTelemetry semantic conventions. (#1016)
- The environment variable used for resource detection has been changed from `OTEL_RESOURCE_LABELS` to `OTEL_RESOURCE_ATTRIBUTES` (#1042)
- Replace `WithSyncer` with `WithBatcher` in examples. (#1044)
- Replace the `google.golang.org/grpc/codes` dependency in the API with an equivalent `go.opentelemetry.io/otel/codes` package. (#1046)
- Merge the `go.opentelemetry.io/otel/api/label` and `go.opentelemetry.io/otel/api/kv` into the new `go.opentelemetry.io/otel/label` package. (#1060)
- Unify Callback Function Naming.
-   Rename `*Callback` with `*Func`. (#1061)
- CI builds validate against last two versions of Go, dropping 1.13 and adding 1.15. (#1064)
- The `go.opentelemetry.io/otel/sdk/export/trace` interfaces `SpanSyncer` and `SpanBatcher` have been replaced with a specification compliant `Exporter` interface.
-   This interface still supports the export of `SpanData`, but only as a slice.
-   Implementation are also required now to return any error from `ExportSpans` if one occurs as well as implement a `Shutdown` method for exporter clean-up. (#1078)
- The `go.opentelemetry.io/otel/sdk/trace` `NewBatchSpanProcessor` function no longer returns an error.
-   If a `nil` exporter is passed as an argument to this function, instead of it returning an error, it now returns a `BatchSpanProcessor` that handles the export of `SpanData` by not taking any action. (#1078)
- The `go.opentelemetry.io/otel/sdk/trace` `NewProvider` function to create a `Provider` no longer returns an error, instead only a `*Provider`.
-   This change is related to `NewBatchSpanProcessor` not returning an error which was the only error this function would return. (#1078)
-
-### Removed
-
- Duplicate, unused API sampler interface. (#999)
-   Use the [`Sampler` interface](https://github.com/open-telemetry/opentelemetry-go/blob/v0.11.0/sdk/trace/sampling.go) provided by the SDK instead.
- The `grpctrace` instrumentation was moved to the `go.opentelemetry.io/contrib` repository and out of this repository.
-   This move includes moving the `grpc` example to the `go.opentelemetry.io/contrib` as well. (#1027)
- The `WithSpan` method of the `Tracer` interface.
-   The functionality this method provided was limited compared to what a user can provide themselves.
-   It was removed with the understanding that if there is sufficient user need it can be added back based on actual user usage. (#1043)
- The `RegisterSpanProcessor` and `UnregisterSpanProcessor` functions.
-   These were holdovers from an approach prior to the TracerProvider design. They were not used anymore. (#1077)
- The `oterror` package. (#1026)
- The `othttp` and `httptrace` instrumentations were moved to `go.opentelemetry.io/contrib`. (#1032)
-
-### Fixed
-
- The `semconv.HTTPServerMetricAttributesFromHTTPRequest()` function no longer generates the high-cardinality `http.request.content.length` label. (#1031)
- Correct instrumentation version tag in Jaeger exporter. (#1037)
- The SDK span will now set an error event if the `End` method is called during a panic (i.e. it was deferred). (#1043)
- Move internally generated protobuf code from the `go.opentelemetry.io/otel` to the OTLP exporter to reduce dependency overhead. (#1050)
- The `otel-collector` example referenced outdated collector processors. (#1006)
-
-## [0.10.0] - 2020-07-29
-
-This release migrates the default OpenTelemetry SDK into its own Go module, decoupling the SDK from the API and reducing dependencies for instrumentation packages.
-
-### Added
-
- The Zipkin exporter now has `NewExportPipeline` and `InstallNewPipeline` constructor functions to match the common pattern.
-    These function build a new exporter with default SDK options and register the exporter with the `global` package respectively. (#944)
- Add propagator option for gRPC instrumentation. (#986)
- The `testtrace` package now tracks the `trace.SpanKind` for each span. (#987)
-
-### Changed
-
- Replace the `RegisterGlobal` `Option` in the Jaeger exporter with an `InstallNewPipeline` constructor function.
-   This matches the other exporter constructor patterns and will register a new exporter after building it with default configuration. (#944)
- The trace (`go.opentelemetry.io/otel/exporters/trace/stdout`) and metric (`go.opentelemetry.io/otel/exporters/metric/stdout`) `stdout` exporters are now merged into a single exporter at `go.opentelemetry.io/otel/exporters/stdout`.
-   This new exporter was made into its own Go module to follow the pattern of all exporters and decouple it from the `go.opentelemetry.io/otel` module. (#956, #963)
- Move the `go.opentelemetry.io/otel/exporters/test` test package to `go.opentelemetry.io/otel/sdk/export/metric/metrictest`. (#962)
- The `go.opentelemetry.io/otel/api/kv/value` package was merged into the parent `go.opentelemetry.io/otel/api/kv` package. (#968)
-  - `value.Bool` was replaced with `kv.BoolValue`.
-  - `value.Int64` was replaced with `kv.Int64Value`.
-  - `value.Uint64` was replaced with `kv.Uint64Value`.
-  - `value.Float64` was replaced with `kv.Float64Value`.
-  - `value.Int32` was replaced with `kv.Int32Value`.
-  - `value.Uint32` was replaced with `kv.Uint32Value`.
-  - `value.Float32` was replaced with `kv.Float32Value`.
-  - `value.String` was replaced with `kv.StringValue`.
-  - `value.Int` was replaced with `kv.IntValue`.
-  - `value.Uint` was replaced with `kv.UintValue`.
-  - `value.Array` was replaced with `kv.ArrayValue`.
- Rename `Infer` to `Any` in the `go.opentelemetry.io/otel/api/kv` package. (#972)
- Change `othttp` to use the `httpsnoop` package to wrap the `ResponseWriter` so that optional interfaces (`http.Hijacker`, `http.Flusher`, etc.) that are implemented by the original `ResponseWriter`are also implemented by the wrapped `ResponseWriter`. (#979)
- Rename `go.opentelemetry.io/otel/sdk/metric/aggregator/test` package to `go.opentelemetry.io/otel/sdk/metric/aggregator/aggregatortest`. (#980)
- Make the SDK into its own Go module called `go.opentelemetry.io/otel/sdk`. (#985)
- Changed the default trace `Sampler` from `AlwaysOn` to `ParentOrElse(AlwaysOn)`. (#989)
-
-### Removed
-
- The `IndexedAttribute` function from the `go.opentelemetry.io/otel/api/label` package was removed in favor of `IndexedLabel` which it was synonymous with. (#970)
-
-### Fixed
-
- Bump github.com/golangci/golangci-lint from 1.28.3 to 1.29.0 in /tools. (#953)
- Bump github.com/google/go-cmp from 0.5.0 to 0.5.1. (#957)

-
-## [0.9.0] - 2020-07-20
-
-### Added
-
- A new Resource Detector interface is included to allow resources to be automatically detected and included. (#939)
- A Detector to automatically detect resources from an environment variable. (#939)
- Github action to generate protobuf Go bindings locally in `internal/opentelemetry-proto-gen`. (#938)
- OTLP .proto files from `open-telemetry/opentelemetry-proto` imported as a git submodule under `internal/opentelemetry-proto`.
-   References to `github.com/open-telemetry/opentelemetry-proto` changed to `go.opentelemetry.io/otel/internal/opentelemetry-proto-gen`. (#942)
-
-### Changed
-
- Non-nil value `struct`s for key-value pairs will be marshalled using JSON rather than `Sprintf`. (#948)
-
-### Removed
-
- Removed dependency on `github.com/open-telemetry/opentelemetry-collector`. (#943)
-
-## [0.8.0] - 2020-07-09
-
-### Added
-
- The `B3Encoding` type to represent the B3 encoding(s) the B3 propagator can inject.
-   A value for HTTP supported encodings (Multiple Header: `MultipleHeader`, Single Header: `SingleHeader`) are included. (#882)
- The `FlagsDeferred` trace flag to indicate if the trace sampling decision has been deferred. (#882)
- The `FlagsDebug` trace flag to indicate if the trace is a debug trace. (#882)
- Add `peer.service` semantic attribute. (#898)
- Add database-specific semantic attributes. (#899)
- Add semantic convention for `faas.coldstart` and `container.id`. (#909)
- Add http content size semantic conventions. (#905)
- Include `http.request_content_length` in HTTP request basic attributes. (#905)
- Add semantic conventions for operating system process resource attribute keys. (#919)
- The Jaeger exporter now has a `WithBatchMaxCount` option to specify the maximum number of spans sent in a batch. (#931)
-
-### Changed
-
- Update `CONTRIBUTING.md` to ask for updates to `CHANGELOG.md` with each pull request. (#879)
- Use lowercase header names for B3 Multiple Headers. (#881)
- The B3 propagator `SingleHeader` field has been replaced with `InjectEncoding`.
-   This new field can be set to combinations of the `B3Encoding` bitmasks and will inject trace information in these encodings.
-   If no encoding is set, the propagator will default to `MultipleHeader` encoding. (#882)
- The B3 propagator now extracts from either HTTP encoding of B3 (Single Header or Multiple Header) based on what is contained in the header.
-   Preference is given to Single Header encoding with Multiple Header being the fallback if Single Header is not found or is invalid.
-   This behavior change is made to dynamically support all correctly encoded traces received instead of having to guess the expected encoding prior to receiving. (#882)
- Extend semantic conventions for RPC. (#900)
- To match constant naming conventions in the `api/standard` package, the `FaaS*` key names are appended with a suffix of `Key`. (#920)
-  - `"api/standard".FaaSName` -> `FaaSNameKey`
-  - `"api/standard".FaaSID` -> `FaaSIDKey`
-  - `"api/standard".FaaSVersion` -> `FaaSVersionKey`
-  - `"api/standard".FaaSInstance` -> `FaaSInstanceKey`
-
-### Removed
-
- The `FlagsUnused` trace flag is removed.
-   The purpose of this flag was to act as the inverse of `FlagsSampled`, the inverse of `FlagsSampled` is used instead. (#882)
- The B3 header constants (`B3SingleHeader`, `B3DebugFlagHeader`, `B3TraceIDHeader`, `B3SpanIDHeader`, `B3SampledHeader`, `B3ParentSpanIDHeader`) are removed.
-   If B3 header keys are needed [the authoritative OpenZipkin package constants](https://pkg.go.dev/github.com/openzipkin/zipkin-go@v0.2.2/propagation/b3?tab=doc#pkg-constants) should be used instead. (#882)
-
-### Fixed
-
- The B3 Single Header name is now correctly `b3` instead of the previous `X-B3`. (#881)
- The B3 propagator now correctly supports sampling only values (`b3: 0`, `b3: 1`, or `b3: d`) for a Single B3 Header. (#882)
- The B3 propagator now propagates the debug flag.
-   This removes the behavior of changing the debug flag into a set sampling bit.
-   Instead, this now follow the B3 specification and omits the `X-B3-Sampling` header. (#882)
- The B3 propagator now tracks "unset" sampling state (meaning "defer the decision") and does not set the `X-B3-Sampling` header when injecting. (#882)
- Bump github.com/itchyny/gojq from 0.10.3 to 0.10.4 in /tools. (#883)
- Bump github.com/opentracing/opentracing-go from v1.1.1-0.20190913142402-a7454ce5950e to v1.2.0. (#885)
- The tracing time conversion for OTLP spans is now correctly set to `UnixNano`. (#896)
- Ensure span status is not set to `Unknown` when no HTTP status code is provided as it is assumed to be `200 OK`. (#908)
- Ensure `httptrace.clientTracer` closes `http.headers` span. (#912)
- Prometheus exporter will not apply stale updates or forget inactive metrics. (#903)
- Add test for api.standard `HTTPClientAttributesFromHTTPRequest`. (#905)
- Bump github.com/golangci/golangci-lint from 1.27.0 to 1.28.1 in /tools. (#901, #913)
- Update otel-colector example to use the v0.5.0 collector. (#915)
- The `grpctrace` instrumentation uses a span name conforming to the OpenTelemetry semantic conventions (does not contain a leading slash (`/`)). (#922)
- The `grpctrace` instrumentation includes an `rpc.method` attribute now set to the gRPC method name. (#900, #922)
- The `grpctrace` instrumentation `rpc.service` attribute now contains the package name if one exists.
-   This is in accordance with OpenTelemetry semantic conventions. (#922)
- Correlation Context extractor will no longer insert an empty map into the returned context when no valid values are extracted. (#923)
- Bump google.golang.org/api from 0.28.0 to 0.29.0 in /exporters/trace/jaeger. (#925)
- Bump github.com/itchyny/gojq from 0.10.4 to 0.11.0 in /tools. (#926)
- Bump github.com/golangci/golangci-lint from 1.28.1 to 1.28.2 in /tools. (#930)
-
-## [0.7.0] - 2020-06-26
-
-This release implements the v0.5.0 version of the OpenTelemetry specification.
-
-### Added
-
- The othttp instrumentation now includes default metrics. (#861)
- This CHANGELOG file to track all changes in the project going forward.
- Support for array type attributes. (#798)
- Apply transitive dependabot go.mod dependency updates as part of a new automatic Github workflow. (#844)
- Timestamps are now passed to exporters for each export. (#835)
- Add new `Accumulation` type to metric SDK to transport telemetry from `Accumulator`s to `Processor`s.
-   This replaces the prior `Record` `struct` use for this purpose. (#835)
- New dependabot integration to automate package upgrades. (#814)
- `Meter` and `Tracer` implementations accept instrumentation version version as an optional argument.
-   This instrumentation version is passed on to exporters. (#811) (#805) (#802)
- The OTLP exporter includes the instrumentation version in telemetry it exports. (#811)
- Environment variables for Jaeger exporter are supported. (#796)
- New `aggregation.Kind` in the export metric API. (#808)
- New example that uses OTLP and the collector. (#790)
- Handle errors in the span `SetName` during span initialization. (#791)
- Default service config to enable retries for retry-able failed requests in the OTLP exporter and an option to override this default. (#777)
- New `go.opentelemetry.io/otel/api/oterror` package to uniformly support error handling and definitions for the project. (#778)
- New `global` default implementation of the `go.opentelemetry.io/otel/api/oterror.Handler` interface to be used to handle errors prior to an user defined `Handler`.
-   There is also functionality for the user to register their `Handler` as well as a convenience function `Handle` to handle an error with this global `Handler`(#778)
- Options to specify propagators for httptrace and grpctrace instrumentation. (#784)
- The required `application/json` header for the Zipkin exporter is included in all exports. (#774)

-
-### Changed
-
- Rename `Integrator` to `Processor` in the metric SDK. (#863)

- Rename `SynchronizedCopy` to `SynchronizedMove`. (#858)
- Rename `simple` integrator to `basic` integrator. (#857)
- Merge otlp collector examples. (#841)
- Change the metric SDK to support cumulative, delta, and pass-through exporters directly.
-   With these changes, cumulative and delta specific exporters are able to request the correct kind of aggregation from the SDK. (#840)
- The `Aggregator.Checkpoint` API is renamed to `SynchronizedCopy` and adds an argument, a different `Aggregator` into which the copy is stored. (#812)
- The `export.Aggregator` contract is that `Update()` and `SynchronizedCopy()` are synchronized with each other.
-   All the aggregation interfaces (`Sum`, `LastValue`, ...) are not meant to be synchronized, as the caller is expected to synchronize aggregators at a higher level after the `Accumulator`.
-   Some of the `Aggregators` used unnecessary locking and that has been cleaned up. (#812)
- Use of `metric.Number` was replaced by `int64` now that we use `sync.Mutex` in the `MinMaxSumCount` and `Histogram` `Aggregators`. (#812)
- Replace `AlwaysParentSample` with `ParentSample(fallback)` to match the OpenTelemetry v0.5.0 specification. (#810)
- Rename `sdk/export/metric/aggregator` to `sdk/export/metric/aggregation`. #808
- Send configured headers with every request in the OTLP exporter, instead of just on connection creation. (#806)
- Update error handling for any one off error handlers, replacing, instead, with the `global.Handle` function. (#791)
- Rename `plugin` directory to `instrumentation` to match the OpenTelemetry specification. (#779)
- Makes the argument order to Histogram and DDSketch `New()` consistent. (#781)
-
-### Removed

- Renamed `AlwaysSampleSampler` to `AlwaysOnSampler` in the trace API. (#511)
- Renamed `NeverSampleSampler` to `AlwaysOffSampler` in the trace API. (#511)

- Use `NewRoot` in the othttp plugin for public endpoints. (#513)
- Fix data race in `BatchedSpanProcessor`. (#518)
- Skip test-386 for Mac OS 10.15.x (Catalina and upwards). #521

-
-## [0.2.3] - 2020-03-04
-
-### Added
-
- `RecordError` method on `Span`s in the trace API to Simplify adding error events to spans. (#473)
- Configurable push frequency for exporters setup pipeline. (#504)
-
-### Changed
-
- Rename the `exporter` directory to `exporters`.
-   The `go.opentelemetry.io/otel/exporter/trace/jaeger` package was mistakenly released with a `v1.0.0` tag instead of `v0.1.0`.
-   This resulted in all subsequent releases not becoming the default latest.
-   A consequence of this was that all `go get`s pulled in the incompatible `v0.1.0` release of that package when pulling in more recent packages from other otel packages.
-   Renaming the `exporter` directory to `exporters` fixes this issue by renaming the package and therefore clearing any existing dependency tags.
-   Consequentially, this action also renames *all* exporter packages. (#502)
-
-### Removed
-
- The `CorrelationContextHeader` constant in the `correlation` package is no longer exported. (#503)
-
-## [0.2.2] - 2020-02-27

-# Contributing to opentelemetry-go
-
-The Go special interest group (SIG) meets regularly. See the
-OpenTelemetry
-[community](https://github.com/open-telemetry/community#golang-sdk)
-repo for information on this and other language SIGs.
-
-See the [public meeting
-notes](https://docs.google.com/document/d/1A63zSWX0x2CyCK_LoNhmQC4rqhLpYXJzXbEPDUQ2n6w/edit#heading=h.9tngw7jdwd6b)
-for a summary description of past meetings. To request edit access,
-join the meeting or get in touch on
-[Gitter](https://gitter.im/open-telemetry/opentelemetry-go).
-
-## Development
-
-You can view and edit the source code by cloning this repository:
-
-```bash
-git clone https://github.com/open-telemetry/opentelemetry-go.git
-```
-
-Run `make test` to run the tests instead of `go test`. 
-
-There are some generated files checked into the repo. To make sure
-that the generated files are up-to-date, run `make` (or `make
-precommit` - the `precommit` target is the default).
-
-The `precommit` target also fixes the formatting of the code and
-checks the status of the go module files.
-
-If after running `make precommit` the output of `git status` contains
-`nothing to commit, working tree clean` then it means that everything
-is up-to-date and properly formatted.
-
-## Pull Requests
-
-### How to Send Pull Requests
-
-Everyone is welcome to contribute code to `opentelemetry-go` via
-GitHub pull requests (PRs).
-
-To create a new PR, fork the project in GitHub and clone the upstream
-repo:
-
-```sh
-$ go get -d go.opentelemetry.io/otel
-```
-
-(This may print some warning about "build constraints exclude all Go
-files", just ignore it.)
-
-This will put the project in `${GOPATH}/src/go.opentelemetry.io/otel`. You
-can alternatively use `git` directly with:
-
-```sh
-$ git clone https://github.com/open-telemetry/opentelemetry-go
-```
-
-(Note that `git clone` is *not* using the `go.opentelemetry.io/otel` name -
-that name is a kind of a redirector to GitHub that `go get` can
-understand, but `git` does not.)
-
-This would put the project in the `opentelemetry-go` directory in
-current working directory.
-
-Enter the newly created directory and add your fork as a new remote:
-
-```sh
-$ git remote add <YOUR_FORK> git@github.com:<YOUR_GITHUB_USERNAME>/opentelemetry-go
-```
-
-Check out a new branch, make modifications, run linters and tests, update
-`CHANGELOG.md`, and push the branch to your fork:
-
-```sh
-$ git checkout -b <YOUR_BRANCH_NAME>
-# edit files
-# update changelog
-$ make precommit
-$ git add -p
-$ git commit
-$ git push <YOUR_FORK> <YOUR_BRANCH_NAME>
-```
-
-Open a pull request against the main `opentelemetry-go` repo. Be sure to add the pull
-request ID to the entry you added to `CHANGELOG.md`.
-
-### How to Receive Comments
-
-* If the PR is not ready for review, please put `[WIP]` in the title,
-  tag it as `work-in-progress`, or mark it as
-  [`draft`](https://github.blog/2019-02-14-introducing-draft-pull-requests/).
-* Make sure CLA is signed and CI is clear.
-
-### How to Get PRs Merged
-
-A PR is considered to be **ready to merge** when:
-
-* It has received two approvals from Collaborators/Maintainers (at
-  different companies). This is not enforced through technical means
-  and a PR may be **ready to merge** with a single approval if the change
-  and its approach have been discussed and consensus reached.
-* Major feedbacks are resolved.
-* It has been open for review for at least one working day. This gives
-  people reasonable time to review.
-* Trivial changes (typo, cosmetic, doc, etc.) do not have to wait for
-  one day and may be merged with a single Maintainer's approval.
-* `CHANGELOG.md` has been updated to reflect what has been
-  added, changed, removed, or fixed.
-* Urgent fix can take exception as long as it has been actively
-  communicated.
-
-Any Maintainer can merge the PR once it is **ready to merge**.
-
-## Design Choices
-
-As with other OpenTelemetry clients, opentelemetry-go follows the
-[opentelemetry-specification](https://github.com/open-telemetry/opentelemetry-specification).
-
-It's especially valuable to read through the [library
-guidelines](https://github.com/open-telemetry/opentelemetry-specification/blob/master/specification/library-guidelines.md).
-
-### Focus on Capabilities, Not Structure Compliance
-
-OpenTelemetry is an evolving specification, one where the desires and
-use cases are clear, but the method to satisfy those uses cases are
-not.
-
-As such, Contributions should provide functionality and behavior that
-conforms to the specification, but the interface and structure is
-flexible.
-
-It is preferable to have contributions follow the idioms of the
-language rather than conform to specific API names or argument
-patterns in the spec.
-
-For a deeper discussion, see:
-https://github.com/open-telemetry/opentelemetry-specification/issues/165
-
-## Style Guide
-
-One of the primary goals of this project is that it is actually used by
-developers. With this goal in mind the project strives to build
-user-friendly and idiomatic Go code adhering to the Go community's best
-practices.
-
-For a non-comprehensive but foundational overview of these best practices
-the [Effective Go](https://golang.org/doc/effective_go.html) documentation
-is an excellent starting place.
-
-As a convenience for developers building this project the `make precommit`
-will format, lint, validate, and in some cases fix the changes you plan to
-submit. This check will need to pass for your changes to be able to be
-merged.
-
-In addition to idiomatic Go, the project has adopted certain standards for
-implementations of common patterns. These standards should be followed as a
-default, and if they are not followed documentation needs to be included as
-to the reasons why.
-
-### Configuration
-
-When creating an instantiation function for a complex `struct` it is useful
-to allow variable number of options to be applied. However, the strong type
-system of Go restricts the function design options. There are a few ways to
-solve this problem, but we have landed on the following design.
-
-#### `config`
-
-Configuration should be held in a `struct` named `config`, or prefixed with
-specific type name this Configuration applies to if there are multiple
-`config` in the package. This `struct` must contain configuration options.
-
-```go
-// config contains configuration options for a thing.
-type config struct {
-    // options ...
-}
-```
-
-In general the `config` `struct` will not need to be used externally to the
-package and should be unexported. If, however, it is expected that the user
-will likely want to build custom options for the configuration, the `config`
-should be exported. Please, include in the documentation for the `config`
-how the user can extend the configuration.
-
-It is important that `config` are not shared across package boundaries.
-Meaning a `config` from one package should not be directly used by another.
-
-Optionally, it is common to include a `newConfig` function (with the same
-naming scheme). This function wraps any defaults setting and looping over
-all options to create a configured `config`.
-
-```go
-// newConfig returns an appropriately configured config.
-func newConfig([]Option) config {
-    // Set default values for config.
-    config := config{/* […] */}
-    for _, option := range options {
-        option.Apply(&config)
-    }
-    // Preform any validation here.
-    return config
-}
-```
-
-If validation of the `config` options is also preformed this can return an
-error as well that is expected to be handled by the instantiation function
-or propagated to the user.
-
-Given the design goal of not having the user need to work with the `config`,
-the `newConfig` function should also be unexported.
-
-#### `Option`
-
-To set the value of the options a `config` contains, a corresponding
-`Option` interface type should be used.
-
-```go
-type Option interface {
-  Apply(*config)
-}
-```
-
-The name of the interface should be prefixed in the same way the
-corresponding `config` is (if at all).
-
-#### Options
-
-All user configurable options for a `config` must have a related unexported
-implementation of the `Option` interface and an exported configuration
-function that wraps this implementation.
-
-The wrapping function name should be prefixed with `With*` (or in the
-special case of a boolean options `Without*`) and should have the following
-function signature.
-
-```go
-func With*(…) Option { … }
-```
-
-##### `bool` Options
-
-```go
-type defaultFalseOption bool
-
-func (o defaultFalseOption) Apply(c *config) {
-    c.Bool = bool(o)
-}
-
-// WithOption sets a T* to have an option included.
-func WithOption() Option {
-    return defaultFalseOption(true)
-}
-```
-
-```go
-type defaultTrueOption bool
-
-func (o defaultTrueOption) Apply(c *config) {
-    c.Bool = bool(o)
-}
-
-// WithoutOption sets a T* to have Bool option excluded.
-func WithoutOption() Option {
-    return defaultTrueOption(false)
-}
-````
-
-##### Declared Type Options
-
-```go
-type myTypeOption struct {
-    MyType MyType
-}
-
-func (o myTypeOption) Apply(c *config) {
-    c.MyType = o.MyType
-}
-
-// WithMyType sets T* to have include MyType.
-func WithMyType(t MyType) Option {
-    return myTypeOption{t}
-}
-```
-
-#### Instantiation
-
-Using this configuration pattern to configure instantiation with a `New*`
-function.
-
-```go
-func NewT*(options ...Option) T* {…}
-```
-
-Any required parameters can be declared before the variadic `options`.
-
-#### Dealing with Overlap
-
-Sometimes there are multiple complex `struct` that share common
-configuration and also have distinct configuration. To avoid repeated
-portions of `config`s, a common `config` can be used with the union of
-options being handled with the `Option` interface.
-
-For example.
-
-```go
-// config holds options for all animals.
-type config struct {
-	Weight      float64
-	Color       string
-	MaxAltitude float64
-}
-
-// DogOption apply Dog specific options.
-type DogOption interface {
-	ApplyDog(*config)
-}
-
-// BirdOption apply Bird specific options.
-type BirdOption interface {
-	ApplyBird(*config)
-}
-
-// Option apply options for all animals.
-type Option interface {
-	BirdOption
-	DogOption
-}
-
-type weightOption float64
-func (o weightOption) ApplyDog(c *config)  { c.Weight = float64(o) }
-func (o weightOption) ApplyBird(c *config) { c.Weight = float64(o) }
-func WithWeight(w float64) Option          { return weightOption(w) }
-
-type furColorOption string
-func (o furColorOption) ApplyDog(c *config) { c.Color = string(o) }
-func WithFurColor(c string) DogOption       { return furColorOption(c) }
-
-type maxAltitudeOption float64
-func (o maxAltitudeOption) ApplyBird(c *config) { c.MaxAltitude = float64(o) }
-func WithMaxAltitude(a float64) BirdOption      { return maxAltitudeOption(a) }
-
-func NewDog(name string, o ...DogOption) Dog    {…}
-func NewBird(name string, o ...BirdOption) Bird {…}
-```
-
-### Interface Type
-
-To allow other developers to better comprehend the code, it is important
-to ensure it is sufficiently documented. One simple measure that contributes
-to this aim is self-documenting by naming method parameters. Therefore,
-where appropriate, methods of every exported interface type should have
-their parameters appropriately named.

-
-The Go [OpenTelemetry](https://opentelemetry.io/) implementation.
-
-## Getting Started
-
-OpenTelemetry's goal is to provide a single set of APIs to capture distributed
-traces and metrics from your application and send them to an observability
-platform. This project allows you to do just that for applications written in
-Go. There are two steps to this process: instrument your application, and
-configure an exporter.
-
-### Instrumentation
-
-To start capturing distributed traces and metric events from your application
-it first needs to be instrumented. The easiest way to do this is by using an
-instrumentation library for your code. Be sure to check out [the officially
-supported instrumentation
-libraries](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/master/instrumentation).
-
-If you need to extend the telemetry an instrumentation library provides or want
-to build your own instrumentation for your application directly you will need
-to use the
-[go.opentelemetry.io/otel/api](https://pkg.go.dev/go.opentelemetry.io/otel/api)
-package. The included [examples](./example/) are a good way to see some
-practical uses of this process.
-
-### Export
-
-Now that your application is instrumented to collect telemetry, it needs an
-export pipeline to send that telemetry to an observability platform.
-
-You can find officially supported exporters [here](./exporters/) and in the
-companion [contrib
-repository](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/master/exporters/metric).
-Additionally, there are many vendor specific or 3rd party exporters for
-OpenTelemetry. These exporters are broken down by
-[trace](https://pkg.go.dev/go.opentelemetry.io/otel/sdk/export/trace?tab=importedby)
-and
-[metric](https://pkg.go.dev/go.opentelemetry.io/otel/sdk/export/metric?tab=importedby)
-support.
-
-## Project Status
-
-[Project boards](https://github.com/open-telemetry/opentelemetry-go/projects)
-and [milestones](https://github.com/open-telemetry/opentelemetry-go/milestones)
-can be found at the respective links. We try to keep these accurate and should
-be the best place to go for answers on project status.

-# Release Process
-
-## Pre-Release
-
-Update go.mod for submodules to depend on the new release which will happen in the next step.
-
-1. Run the pre-release script. It creates a branch `pre_release_<new tag>` that will contain all release changes.
-
-    ```
-    ./pre_release.sh -t <new tag>
-    ```
-
-2. Verify the changes.
-
-    ```
-    git diff master
-    ```
-
-    This should have changed the version for all modules to be `<new tag>`.
-
-3. Update the [Changelog](./CHANGELOG.md).
-   - Make sure all relevant changes for this release are included and are in language that non-contributors to the project can understand.
-       To verify this, you can look directly at the commits since the `<last tag>`.
-
-       ```
-       git --no-pager log --pretty=oneline "<last tag>..HEAD"
-       ```
-
-   - Move all the `Unreleased` changes into a new section following the title scheme (`[<new tag>] - <date of release>`).
-   - Update all the appropriate links at the bottom.
-
-4. Push the changes to upstream and create a Pull Request on GitHub.
-    Be sure to include the curated changes from the [Changelog](./CHANGELOG.md) in the description.
-
-
-## Tag
-
-Once the Pull Request with all the version changes has been approved and merged it is time to tag the merged commit.
-
-***IMPORTANT***: It is critical you use the same tag that you used in the Pre-Release step!
-Failure to do so will leave things in a broken state.
-
-***IMPORTANT***: [There is currently no way to remove an incorrectly tagged version of a Go module](https://github.com/golang/go/issues/34189).
-It is critical you make sure the version you push upstream is correct.
-[Failure to do so will lead to minor emergencies and tough to work around](https://github.com/open-telemetry/opentelemetry-go/issues/331).
-
-1. Run the tag.sh script using the `<commit-hash>` of the commit on the master branch for the merged Pull Request.
-
-    ```
-    ./tag.sh <new tag> <commit-hash>
-    ```
-
-2. Push tags to the upstream remote (not your fork: `github.com/open-telemetry/opentelemetry-go.git`).
-    Make sure you push all sub-modules as well.
-
-    ```
-    git push upstream <new tag>
-    git push upstream <submodules-path/new tag>
-    ...
-    ```
-
-## Release
-
-Finally create a Release for the new `<new tag>` on GitHub.
-The release body should include all the release notes from the Changelog for this release.
-Additionally, the `tag.sh` script generates commit logs since last release which can be used to supplement the release notes.
-
-## Verify Examples
-
-After releasing verify that examples build outside of the repository.
-
-```
-./verify_examples.sh
-```
-
-The script copies examples into a different directory removes any `replace` declarations in `go.mod` and builds them.
-This ensures they build with the published release, not the local copy.
-
-## Contrib Repository
-
-Once verified be sure to [make a release for the `contrib` repository](https://github.com/open-telemetry/opentelemetry-go-contrib/blob/master/RELEASING.md) that uses this release.

-// Synchronous instruments are called by the user with a Context.
-// Asynchronous instruments are called by the SDK during collection.

-// The synchronous instrument names are:

-//   Counter:           additive, monotonic
-//   UpDownCounter:     additive
-//   ValueRecorder:     non-additive
-//

-//   SumObserver:       additive, monotonic
-//   UpDownSumObserver: additive
-//   ValueObserver:     non-additive
-//
-// All instruments are provided with support for either float64 or
-// int64 input values.
-//
-// The Meter interface supports allocating new instruments as well as
-// interfaces for recording batches of synchronous measurements or
-// asynchronous observations.  To obtain a Meter, use a MeterProvider.
-//
-// The MeterProvider interface supports obtaining a named Meter interface. To
