-### Removed
+## [1.0.0] - 2021-09-20
+
+This is the first stable release for the project.
+This release includes an API and SDK for the tracing signal that will comply with the stability guarantees defined by the projects [versioning policy](./VERSIONING.md).
+
+### Added
+
+- OTLP trace exporter now sets the `SchemaURL` field in the exported telemetry if the Tracer has `WithSchemaURL` option. (#2242)
 
 ### Fixed
 
-### Security
+- Slice-valued attributes can correctly be used as map keys. (#2223)
+
+### Removed
+
+- Removed the `"go.opentelemetry.io/otel/exporters/zipkin".WithSDKOptions` function. (#2248)
+- Removed the deprecated package `go.opentelemetry.io/otel/oteltest`. (#2234)
+- Removed the deprecated package `go.opentelemetry.io/otel/bridge/opencensus/utils`. (#2233)
+- Removed deprecated functions, types, and methods from `go.opentelemetry.io/otel/attribute` package.
+  Use the typed functions and methods added to the package instead. (#2235)
+  - The `Key.Array` method is removed.
+  - The `Array` function is removed.
+  - The `Any` function is removed.
+  - The `ArrayValue` function is removed.
+  - The `AsArray` function is removed.
+
+## [1.0.0-RC3] - 2021-09-02
+
+### Added
+
+- Added `ErrorHandlerFunc` to use a function as an `"go.opentelemetry.io/otel".ErrorHandler`. (#2149)
+- Added `"go.opentelemetry.io/otel/trace".WithStackTrace` option to add a stack trace when using `span.RecordError` or when panic is handled in `span.End`. (#2163)
+- Added typed slice attribute types and functionality to the `go.opentelemetry.io/otel/attribute` package to replace the existing array type and functions. (#2162)
+  - `BoolSlice`, `IntSlice`, `Int64Slice`, `Float64Slice`, and `StringSlice` replace the use of the `Array` function in the package.
+- Added the `go.opentelemetry.io/otel/example/fib` example package.
+  Included is an example application that computes Fibonacci numbers. (#2203)
+
+### Changed
+
+- Metric instruments have been renamed to match the (feature-frozen) metric API specification:
+  - ValueRecorder becomes Histogram
+  - ValueObserver becomes Gauge
+  - SumObserver becomes CounterObserver
+  - UpDownSumObserver becomes UpDownCounterObserver
+  The API exported from this project is still considered experimental. (#2202)
+- Metric SDK/API implementation type `InstrumentKind` moves into `sdkapi` sub-package. (#2091)
+- The Metrics SDK export record no longer contains a Resource pointer, the SDK `"go.opentelemetry.io/otel/sdk/trace/export/metric".Exporter.Export()` function for push-based exporters now takes a single Resource argument, pull-based exporters use `"go.opentelemetry.io/otel/sdk/metric/controller/basic".Controller.Resource()`. (#2120)
+- The JSON output of the `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` is harmonized now such that the output is "plain" JSON objects after each other of the form `{ ... } { ... } { ... }`. Earlier the JSON objects describing a span were wrapped in a slice for each `Exporter.ExportSpans` call, like `[ { ... } ][ { ... } { ... } ]`. Outputting JSON object directly after each other is consistent with JSON loggers, and a bit easier to parse and read. (#2196)
+- Update the `NewTracerConfig`, `NewSpanStartConfig`, `NewSpanEndConfig`, and `NewEventConfig` function in the `go.opentelemetry.io/otel/trace` package to return their respective configurations as structs instead of pointers to the struct. (#2212)
+
+### Deprecated
+
+- The `go.opentelemetry.io/otel/bridge/opencensus/utils` package is deprecated.
+  All functionality from this package now exists in the `go.opentelemetry.io/otel/bridge/opencensus` package.
+  The functions from that package should be used instead. (#2166)
+- The `"go.opentelemetry.io/otel/attribute".Array` function and the related `ARRAY` value type is deprecated.
+  Use the typed `*Slice` functions and types added to the package instead. (#2162)
+- The `"go.opentelemetry.io/otel/attribute".Any` function is deprecated.
+  Use the typed functions instead. (#2181)
+- The `go.opentelemetry.io/otel/oteltest` package is deprecated.
+  The `"go.opentelemetry.io/otel/sdk/trace/tracetest".SpanRecorder` can be registered with the default SDK (`go.opentelemetry.io/otel/sdk/trace`) as a `SpanProcessor` and used as a replacement for this deprecated package. (#2188)
+
+### Removed
+
+- Removed metrics test package `go.opentelemetry.io/otel/sdk/export/metric/metrictest`. (#2105)
+
+### Fixed
+
+- The `fromEnv` detector no longer throws an error when `OTEL_RESOURCE_ATTRIBUTES` environment variable is not set or empty. (#2138)
+- Setting the global `ErrorHandler` with `"go.opentelemetry.io/otel".SetErrorHandler` multiple times is now supported. (#2160, #2140)
+- The `"go.opentelemetry.io/otel/attribute".Any` function now supports `int32` values. (#2169)
+- Multiple calls to `"go.opentelemetry.io/otel/sdk/metric/controller/basic".WithResource()` are handled correctly, and when no resources are provided `"go.opentelemetry.io/otel/sdk/resource".Default()` is used. (#2120)
+- The `WithoutTimestamps` option for the `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` exporter causes the exporter to correctly ommit timestamps. (#2195)
+- Fixed typos in resources.go. (#2201)
+
+## [1.0.0-RC2] - 2021-07-26
+
+### Added
+
+- Added `WithOSDescription` resource configuration option to set OS (Operating System) description resource attribute (`os.description`). (#1840)
+- Added `WithOS` resource configuration option to set all OS (Operating System) resource attributes at once. (#1840)
+- Added the `WithRetry` option to the `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` package.
+  This option is a replacement for the removed `WithMaxAttempts` and `WithBackoff` options. (#2095)
+- Added API `LinkFromContext` to return Link which encapsulates SpanContext from provided context and also encapsulates attributes. (#2115)
+- Added a new `Link` type under the SDK `otel/sdk/trace` package that counts the number of attributes that were dropped for surpassing the `AttributePerLinkCountLimit` configured in the Span's `SpanLimits`.
+  This new type replaces the equal-named API `Link` type found in the `otel/trace` package for most usages within the SDK.
+  For example, instances of this type are now returned by the `Links()` function of `ReadOnlySpan`s provided in places like the `OnEnd` function of `SpanProcessor` implementations. (#2118)
+- Added the `SpanRecorder` type to the `go.opentelemetry.io/otel/skd/trace/tracetest` package.
+  This type can be used with the default SDK as a `SpanProcessor` during testing. (#2132)
+
+### Changed
+
+- The `SpanModels` function is now exported from the `go.opentelemetry.io/otel/exporters/zipkin` package to convert OpenTelemetry spans into Zipkin model spans. (#2027)
+- Rename the `"go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc".RetrySettings` to `RetryConfig`. (#2095)
+
+### Deprecated
+
+- The `TextMapCarrier` and `TextMapPropagator` from the `go.opentelemetry.io/otel/oteltest` package and their associated creation functions (`TextMapCarrier`, `NewTextMapPropagator`) are deprecated. (#2114)
+- The `Harness` type from the `go.opentelemetry.io/otel/oteltest` package and its associated creation function, `NewHarness` are deprecated and will be removed in the next release. (#2123)
+- The `TraceStateFromKeyValues` function from the `go.opentelemetry.io/otel/oteltest` package is deprecated.
+  Use the `trace.ParseTraceState` function instead. (#2122)
+
+### Removed
+
+- Removed the deprecated package `go.opentelemetry.io/otel/exporters/trace/jaeger`. (#2020)
+- Removed the deprecated package `go.opentelemetry.io/otel/exporters/trace/zipkin`. (#2020)
+- Removed the `"go.opentelemetry.io/otel/sdk/resource".WithBuiltinDetectors` function.
+  The explicit `With*` options for every built-in detector should be used instead. (#2026 #2097)
+- Removed the `WithMaxAttempts` and `WithBackoff` options from the `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` package.
+  The retry logic of the package has been updated to match the `otlptracegrpc` package and accordingly a `WithRetry` option is added that should be used instead. (#2095)
+- Removed `DroppedAttributeCount` field from `otel/trace.Link` struct. (#2118)
+
+### Fixed
+
+- When using WithNewRoot, don't use the parent context for making sampling decisions. (#2032)
+- `oteltest.Tracer` now creates a valid `SpanContext` when using `WithNewRoot`. (#2073)
+- OS type detector now sets the correct `dragonflybsd` value for DragonFly BSD. (#2092)
+- The OTel span status is correctly transformed into the OTLP status in the `go.opentelemetry.io/otel/exporters/otlp/otlptrace` package.
+  This fix will by default set the status to `Unset` if it is not explicitly set to `Ok` or `Error`. (#2099 #2102)
+- The `Inject` method for the `"go.opentelemetry.io/otel/propagation".TraceContext` type no longer injects empty `tracestate` values. (#2108)
+- Use `6831` as default Jaeger agent port instead of `6832`. (#2131)
+
+## [Experimental Metrics v0.22.0] - 2021-07-19
+
+### Added
+
+- Adds HTTP support for OTLP metrics exporter. (#2022)
+
+### Removed
+
+- Removed the deprecated package `go.opentelemetry.io/otel/exporters/metric/prometheus`. (#2020)

+# OpenTelemetry-Go OTLP Span Exporter
+
+[![Go Reference](https://pkg.go.dev/badge/go.opentelemetry.io/otel/exporters/otlp/otlptrace.svg)](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace)
+
+[OpenTelemetry Protocol Exporter](https://github.com/open-telemetry/opentelemetry-specification/blob/v1.5.0/specification/protocol/exporter.md) implementation.
+
+## Installation
+
+```
+go get -u go.opentelemetry.io/otel/exporters/otlp/otlptrace
+```
+
+## Examples
+
+- [Exporter setup and examples](./otlptracehttp/example_test.go)
+- [Full example sending telemetry to a local collector](../../../example/otel-collector)
+
+## [`otlptrace`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace)
+
+The `otlptrace` package provides an exporter implementing the OTel span exporter interface.
+This exporter is configured using a client satisfying the `otlptrace.Client` interface.
+This client handles the transformation of data into wire format and the transmission of that data to the collector.
+
+## [`otlptracegrpc`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc)
+
+The `otlptracegrpc` package implements a client for the span exporter that sends trace telemetry data to the collector using gRPC with protobuf-encoded payloads.
+
+## [`otlptracehttp`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp)
+
+The `otlptracehttp` package implements a client for the span exporter that sends trace telemetry data to the collector using HTTP with protobuf-encoded payloads.
+
+## Configuration
+
+### Environment Variables
+
+The following environment variables can be used
+(instead of options objects) to override the default configuration.
+
+| Environment variable                                                     | Option                        | Default value                       |
+| ------------------------------------------------------------------------ |------------------------------ | ----------------------------------- |
+| `OTEL_EXPORTER_OTLP_ENDPOINT` `OTEL_EXPORTER_OTLP_TRACES_ENDPOINT`       | `WithEndpoint` `WithInsecure` | `https://localhost:4317`            |
+| `OTEL_EXPORTER_OTLP_CERTIFICATE` `OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE` | `WithTLSClientConfig`         |                                     |
+| `OTEL_EXPORTER_OTLP_HEADERS` `OTEL_EXPORTER_OTLP_TRACES_HEADERS`         | `WithHeaders`                 |                                     |
+| `OTEL_EXPORTER_OTLP_COMPRESSION` `OTEL_EXPORTER_OTLP_TRACES_COMPRESSION` | `WithCompression`             |                                     |
+| `OTEL_EXPORTER_OTLP_TIMEOUT` `OTEL_EXPORTER_OTLP_TRACES_TIMEOUT`         | `WithTimeout`                 | `10s`                               |
+
+Configuration using options have precedence over the environment variables.
