This project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [Unreleased]
### Added
- Support for stdoutlog exporter in `go.opentelemetry.io/contrib/config`. (#5850)
- Add macOS ARM64 platform to the compatibility testing suite. (#5868)
- The `go.opentelemetry.io/contrib/bridges/otelzap` module.
This module provides an OpenTelemetry logging bridge for `go.uber.org/zap`. (#5191)
- The `go.opentelemetry.io/contrib/config` package supports configuring `with_resource_constant_labels` for the prometheus exporter. (#5890)
- Add new runtime metrics to `go.opentelemetry.io/contrib/instrumentation/runtime`, which are still disabled by default. (#5870)
- Support for the `OTEL_HTTP_CLIENT_COMPATIBILITY_MODE=http/dup` environment variable in `go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp` to emit attributes for both the v1.20.0 and v1.24.0 semantic conventions. (#5401)
### Removed
- The deprecated `go.opentelemetry.io/contrib/processors/baggagecopy` package is removed. (#5853)
<!-- Released section -->
<!-- Don't change this section unless doing release -->
## [1.28.0/0.53.0/0.22.0/0.8.0/0.3.0/0.1.0] - 2024-07-02
### Added
- Add the new `go.opentelemetry.io/contrib/detectors/azure/azurevm` package to provide a resource detector for Azure VMs. (#5422)
- Add support to configure views when creating MeterProvider using the config package. (#5654)
- The `go.opentelemetry.io/contrib/config` add support to configure periodic reader interval and timeout. (#5661)
- Add log support for the autoexport package. (#5733)
- Add support for disabling the old runtime metrics using the `OTEL_GO_X_DEPRECATED_RUNTIME_METRICS=false` environment variable. (#5747)
- Add support for signal-specific protocols environment variables (`OTEL_EXPORTER_OTLP_TRACES_PROTOCOL`, `OTEL_EXPORTER_OTLP_LOGS_PROTOCOL`, `OTEL_EXPORTER_OTLP_METRICS_PROTOCOL`) in `go.opentelemetry.io/contrib/exporters/autoexport`. (#5816)
- The `go.opentelemetry.io/contrib/processors/minsev` module is added.
This module provides and experimental logging processor with a configurable threshold for the minimum severity records must have to be recorded. (#5817)
- The `go.opentelemetry.io/contrib/processors/baggagecopy` module.
This module is a replacement of `go.opentelemetry.io/contrib/processors/baggage/baggagetrace`. (#5824)
### Changed
- Improve performance of `go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc` with the usage of `WithAttributeSet()` instead of `WithAttribute()`. (#5664)
- Improve performance of `go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp` with the usage of `WithAttributeSet()` instead of `WithAttribute()`. (#5664)
- Update `go.opentelemetry.io/contrib/config` to latest released configuration schema which introduces breaking changes where `Attributes` is now a `map[string]interface{}`. (#5758)
- Upgrade all dependencies of `go.opentelemetry.io/otel/semconv/v1.25.0` to `go.opentelemetry.io/otel/semconv/v1.26.0`. (#5847)
### Fixed
- Custom attributes targeting metrics recorded by the `go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp` are not ignored anymore. (#5129)
- The double setup in `go.opentelemetry.io/contrib/instrumentation/net/http/httptrace/otelhttptrace/example` that caused duplicate traces. (#5564)
- The superfluous `response.WriteHeader` call in `go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp` when the response writer is flushed. (#5634)
- Use `c.FullPath()` method to set `http.route` attribute in `go.opentelemetry.io/contrib/instrumentation/github.com/gin-gonic/gin/otelgin`. (#5734)
- Out-of-bounds panic in case of invalid span ID in `go.opentelemetry.io/contrib/propagators/b3`. (#5754)
### Deprecated
- The `go.opentelemetry.io/contrib/instrumentation/github.com/labstack/echo/otelecho` package is deprecated.
If you would like to become a Code Owner of this module and prevent it from being removed, see [#5550]. (#5645)
- The `go.opentelemetry.io/contrib/instrumentation/gopkg.in/macaron.v1/otelmacaron` package is deprecated.
If you would like to become a Code Owner of this module and prevent it from being removed, see [#5552]. (#5646)
- The `go.opentelemetry.io/contrib/samplers/aws/xray` package is deprecated.
If you would like to become a Code Owner of this module and prevent it from being removed, see [#5554]. (#5647)
- The `go.opentelemetry.io/contrib/processors/baggage/baggagetrace` package is deprecated.
Use the added `go.opentelemetry.io/contrib/processors/baggagecopy` package instead. (#5824)
- Use `baggagecopy.NewSpanProcessor` as a replacement for `baggagetrace.New`.
- `NewSpanProcessor` accepts a `Fitler` function type that selects which baggage members are added to a span.
- `NewSpanProcessor` returns a `*baggagecopy.SpanProcessor` instead of a `trace.SpanProcessor` interface.
The returned type still implements the interface.

- Add `WithFallbackMetricProducer` option that adds a fallback if the `OTEL_METRICS_PRODUCERS` is not set or empty.
- The `go.opentelemetry.io/contrib/processors/baggage/baggagetrace` module. This module provides a Baggage Span Processor. (#5404)

This option function is used as a replacement of `WithInstrumentationScope` to specify the logged package version. (#5588)
- The `WithSchemaURL` option function in `go.opentelemetry.io/contrib/bridges/otelslog`.
This option function is used as a replacement of `WithInstrumentationScope` to specify the semantic convention schema URL for the logged records. (#5588)
- Add support for Cloud Run jobs in `go.opentelemetry.io/contrib/detectors/gcp`. (#5559)

This package implements the Jaeger remote sampler for OpenTelemetry Go. (#936)
- DynamoDB spans created with the `go.opentelemetry.io/contrib/instrumentation/github.com/aws/aws-sdk-go-v2/otelaws` package now have the appropriate database attributes added for the operation being performed.
These attributes are detected automatically, but it is also now possible to provide a custom function to set attributes using `WithAttributeSetter`. (#1582)
- Add resource detector for GCP cloud function. (#1584)
- Add OpenTracing baggage extraction to the OpenTracing propagator in `go.opentelemetry.io/contrib/propagators/ot`. (#1880)

This changes fixes the code to comply with the OpenTelemetry specification. (#1414, #1537)
- Fixed the region reported by the `"go.opentelemetry.io/contrib/detectors/gcp".CloudRun` detector to comply with the OpenTelemetry specification.
It no longer includes the project scoped region path, instead just the region. (#1546)
- The `"go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp".Transport` type now correctly handles protocol switching responses.
The returned response body implements the `io.ReadWriteCloser` interface if the underlying one does.
