+
+## Installation
+
+go-redis supports 2 last Go versions and requires a Go version with
+[modules](https://github.com/golang/go/wiki/Modules) support. So make sure to initialize a Go
+module:
+
+```shell
+go mod init github.com/my/repo
+```
+
+And then install go-redis (note _v8_ in the import; omitting it is a popular mistake):
+
+```shell
+go get github.com/go-redis/redis/v8
+```
+
+## Quickstart
+
+```go
+import (
+    "context"
+    "github.com/go-redis/redis/v8"
+)
+
+var ctx = context.Background()
+
+func ExampleClient() {
+    rdb := redis.NewClient(&redis.Options{
+        Addr:     "localhost:6379",
+        Password: "", // no password set
+        DB:       0,  // use default DB
+    })
+
+    err := rdb.Set(ctx, "key", "value", 0).Err()
+    if err != nil {
+        panic(err)
+    }
+
+    val, err := rdb.Get(ctx, "key").Result()
+    if err != nil {
+        panic(err)
+    }
+    fmt.Println("key", val)
+
+    val2, err := rdb.Get(ctx, "key2").Result()
+    if err == redis.Nil {
+        fmt.Println("key2 does not exist")
+    } else if err != nil {
+        panic(err)
+    } else {
+        fmt.Println("key2", val2)
+    }
+    // Output: key value
+    // key2 does not exist
+}
+```
+
+## Look and feel
+
+Some corner cases:
+
+```go
+// SET key value EX 10 NX
+set, err := rdb.SetNX(ctx, "key", "value", 10*time.Second).Result()
+
+// SET key value keepttl NX
+set, err := rdb.SetNX(ctx, "key", "value", redis.KeepTTL).Result()
+
+// SORT list LIMIT 0 2 ASC
+vals, err := rdb.Sort(ctx, "list", &redis.Sort{Offset: 0, Count: 2, Order: "ASC"}).Result()
+
+// ZRANGEBYSCORE zset -inf +inf WITHSCORES LIMIT 0 2
+vals, err := rdb.ZRangeByScoreWithScores(ctx, "zset", &redis.ZRangeBy{
+    Min: "-inf",
+    Max: "+inf",
+    Offset: 0,
+    Count: 2,
+}).Result()
+
+// ZINTERSTORE out 2 zset1 zset2 WEIGHTS 2 3 AGGREGATE SUM
+vals, err := rdb.ZInterStore(ctx, "out", &redis.ZStore{
+    Keys: []string{"zset1", "zset2"},
+    Weights: []int64{2, 3}
+}).Result()
+
+// EVAL "return {KEYS[1],ARGV[1]}" 1 "key" "hello"
+vals, err := rdb.Eval(ctx, "return {KEYS[1],ARGV[1]}", []string{"key"}, "hello").Result()
+
+// custom command
+res, err := rdb.Do(ctx, "set", "key", "value").Result()
+```

+
+## [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)

+- Fix missing shutdown processor in otel-collector example. (#1186)
+- Fix missing shutdown processor in basic and namedtracer examples. (#1197)
+
+## [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)
+- Use `global.Handle` for span export errors in the OTLP exporter. (#946)
+- Correct Go language formatting in the README documentation. (#961)
+- Remove default SDK dependencies from the `go.opentelemetry.io/otel/api` package. (#977)
+- Remove default SDK dependencies from the `go.opentelemetry.io/otel/instrumentation` package. (#983)
+- Move documented examples for `go.opentelemetry.io/otel/instrumentation/grpctrace` interceptors into Go example tests. (#984)
+
+## [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)
+- Integrate HTTP semantics helpers from the contrib repository into the `api/standard` package. #769
+
+### Changed
+
+- Rename `Integrator` to `Processor` in the metric SDK. (#863)
+- Rename `AggregationSelector` to `AggregatorSelector`. (#859)
+- 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
+
+- `Uint64NumberKind` and related functions from the API. (#864)
+- Context arguments from `Aggregator.Checkpoint` and `Integrator.Process` as they were unused. (#803)
+- `SpanID` is no longer included in parameters for sampling decision to match the OpenTelemetry specification. (#775)
+
+### Fixed
+
+- Upgrade OTLP exporter to opentelemetry-proto matching the opentelemetry-collector v0.4.0 release. (#866)
+- Allow changes to `go.sum` and `go.mod` when running dependabot tidy-up. (#871)
+- Bump github.com/stretchr/testify from 1.4.0 to 1.6.1. (#824)
+- Bump github.com/prometheus/client_golang from 1.7.0 to 1.7.1 in /exporters/metric/prometheus. (#867)

+### Added
+

+- Context propagation in OpenTracing bridge in terms of OpenTelemetry context propagation. (#525)
+- The `Resource` type was added to the SDK. (#528)
+- The global API now supports a `Tracer` and `Meter` function as shortcuts to getting a global `*Provider` and calling these methods directly. (#538)
+- The metric API now defines a generic `MeterImpl` interface to support general purpose `Meter` construction.
+   Additionally, `SyncImpl` and `AsyncImpl` are added to support general purpose instrument construction. (#560)
+- A metric `Kind` is added to represent the `MeasureKind`, `ObserverKind`, and `CounterKind`. (#560)
+- Scripts to better automate the release process. (#576)
+
+### Changed
+
+- Default to to use `AlwaysSampler` instead of `ProbabilitySampler` to match OpenTelemetry specification. (#506)
+- Renamed `AlwaysSampleSampler` to `AlwaysOnSampler` in the trace API. (#511)
+- Renamed `NeverSampleSampler` to `AlwaysOffSampler` in the trace API. (#511)
+- The `Status` field of the `Span` was changed to `StatusCode` to disambiguate with the added `StatusMessage`. (#524)
+- Updated the trace `Sampler` interface conform to the OpenTelemetry specification. (#531)
+- Rename metric API `Options` to `Config`. (#541)
+- Rename metric `Counter` aggregator to be `Sum`. (#541)
+- Unify metric options into `Option` from instrument specific options. (#541)
+- The trace API's `TraceProvider` now support `Resource`s. (#545)
+- Correct error in zipkin module name. (#548)
+- The jaeger trace exporter now supports `Resource`s. (#551)
+- Metric SDK now supports `Resource`s.
+   The `WithResource` option was added to configure a `Resource` on creation and the `Resource` method was added to the metric `Descriptor` to return the associated `Resource`. (#552)
+- Replace `ErrNoLastValue` and `ErrEmptyDataSet` by `ErrNoData` in the metric SDK. (#557)
+- The stdout trace exporter now supports `Resource`s. (#558)
+- The metric `Descriptor` is now included at the API instead of the SDK. (#560)
+- Replace `Ordered` with an iterator in `export.Labels`. (#567)
+
+### Removed
+
+- The vendor specific Stackdriver. It is now hosted on 3rd party vendor infrastructure. (#452)
+- The `Unregister` method for metric observers as it is not in the OpenTelemetry specification. (#560)
+- `GetDescriptor` from the metric SDK. (#575)
+- The `Gauge` instrument from the metric API. (#537)
+
+### Fixed
+
+- Make histogram aggregator checkpoint consistent. (#438)
+- Update README with import instructions and how to build and test. (#505)
+- The default label encoding was updated to be unique. (#508)
+- 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

+- Provide an implementation of the `Header*` filters that do not depend on Go 1.14. (#565)
+- Encode labels once during checkpoint.
+   The checkpoint function is executed in a single thread so we can do the encoding lazily before passing the encoded version of labels to the exporter.
+   This is a cheap and quick way to avoid encoding the labels on every collection interval. (#572)
+- Run coverage over all packages in `COVERAGE_MOD_DIR`. (#573)
+
+## [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
+
+### Added
+

+- Reword function documentation in gRPC plugin. (#446)
+- Send the `span.kind` tag to Jaeger from the jaeger exporter. (#441)
