### Added
- Support `OTEL_EXPORTER_OTLP_LOGS_INSECURE` and
`OTEL_EXPORTER_OTLP_INSECURE` environments in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#5739)
- The `WithResource` option for `NewMeterProvider` now merges the
provided resources with the ones from environment variables. (#5773)
- The `WithResource` option for `NewLoggerProvider` now merges the
provided resources with the ones from environment variables. (#5773)
- Add UTF-8 support to `go.opentelemetry.io/otel/exporters/prometheus`.
(#5755)
### Fixed
- Fix memory leak in the global `MeterProvider` when identical
instruments are repeatedly created. (#5754)
- Fix panic instruments creation when setting meter provider. (#5758)
- Fix panic on instruments creation when setting meter provider. (#5758)
- Fix an issue where `SetMeterProvider` in `go.opentelemetry.io/otel`
might miss the delegation for instruments and registries. (#5780)
### Removed
- Drop support for [Go 1.21](https://go.dev/doc/go1.21). (#5736, #5740,
#5800)

### Changes
Disable sanitization when the UTF-8 support is enabled in the Prometheus
library.
### Usage
To enable UTF-8 support for the Prometheus exporter after this change,
set the following in your application:
```golang
import "github.com/prometheus/common/model"
func init() {
model.NameValidationScheme = model.UTF8Validation
}
```
See `exporters/prometheus/testdata/counter_utf8.txt` for an example of
the text exposition format including names/labels with dots.
Closes#5757
This PR fixes an issue where `SetMeterProvider` might miss the
delegation for instruments and registries. This bug brings a concurrent
issue that could possibly make instruments and registries unable to
operate correctly, such as recording, after using the `SetMeterProvider`
method. The data put on these instruments and registries might be lost.
Closes https://github.com/open-telemetry/opentelemetry-go/issues/5719
In this commit I add OTEL_EXPORTER_OTLP_LOGS_INSECURE and
OTEL_EXPORTER_OTLP_INSECURE env options to `otlploggrpc.Exporter`.
Now insecure option is fetched from env endpoint value
(OTEL_EXPORTER_OTLP_LOGS_ENDPOINT/OTEL_EXPORTER_OTLP_ENDPOINT).
According to
[spec](https://opentelemetry.io/docs/specs/otel/protocol/exporter/):
> Insecure: Whether to enable client transport security for the
exporter’s gRPC connection. This option only applies to OTLP/gRPC when
an endpoint is provided without the http or https scheme - OTLP/HTTP
always uses the scheme provided for the endpoint.
So with current behavior we have several problems:
- If default endpoint is used, we can't use insecure connection (with
setting OTEL_EXPORTER_OTLP_INSECURE).
- If endpoint provided with option without scheme (e.g. `WithEndpoint`)
we can't use insecure connection with env settings.
- If endpoint provided with env variable without scheme (e.g.
`//env.endpoint:8080/`) we can't use insecure connection.
This commit fixes this.
The same problem with `otlploghttp.Exporter`, and probably it should be
fixed there too.
I'm open to suggestions on how to fix the current behavior in a more
elegant way.

With the `write` option, codespell fixes issues (which is a nice
behavior when we run it locally), but it also returns a 0 status code
(except if some failures couldn't be fixed).
So in order to actually fix the CI on a failing codespell, we need to
ensure the working directory is clean.

This release is the last to support [Go 1.21]. The next release will
require at least [Go 1.22].
### Added
- Add MacOS ARM64 platform to the compatibility testing suite. (#5577)
- Add `InstrumentationScope` field to `SpanStub` in
`go.opentelemetry.io/otel/sdk/trace/tracetest`, as a replacement for the
deprecated `InstrumentationLibrary`. (#5627)
- Make the initial release of
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. This new
module contains an OTLP exporter that transmits log telemetry using
gRPC. This module is unstable and breaking changes may be introduced.
See our [versioning policy](VERSIONING.md) for more information about
these stability guarantees. (#5629)
- Add `Walk` function to `TraceState` in
`go.opentelemetry.io/otel/trace` to iterate all the key-value pairs.
(#5651)
- Bridge the trace state in
`go.opentelemetry.io/otel/bridge/opencensus`. (#5651)
- Zero value of `SimpleProcessor` in `go.opentelemetry.io/otel/sdk/log`
no longer panics. (#5665)
- The `FilterProcessor` interface type is added in
`go.opentelemetry.io/otel/sdk/log/internal/x`. This is an optional and
experimental interface that log `Processor`s can implement to instruct
the `Logger` if a `Record` will be processed or not. It replaces the
existing `Enabled` method that is removed from the `Processor` interface
itself. It does not fall within the scope of the OpenTelemetry Go
versioning and stability [policy](./VERSIONING.md) and it may be changed
in backwards incompatible ways or removed in feature releases. (#5692)
- Support [Go 1.23]. (#5720)
### Changed
- `NewMemberRaw`, `NewKeyProperty` and `NewKeyValuePropertyRaw` in
`go.opentelemetry.io/otel/baggage` allow UTF-8 string in key. (#5132)
- `Processor.OnEmit` in `go.opentelemetry.io/otel/sdk/log` now accepts a
pointer to `Record` instead of a value so that the record modifications
done in a processor are propagated to subsequent registered processors.
(#5636)
- `SimpleProcessor.Enabled` in `go.opentelemetry.io/otel/sdk/log` now
returns `false` if the exporter is `nil`. (#5665)
- Update the concurrency requirements of `Exporter` in
`go.opentelemetry.io/otel/sdk/log`. (#5666)
- `SimpleProcessor` in `go.opentelemetry.io/otel/sdk/log` synchronizes
`OnEmit` calls. (#5666)
- The `Processor` interface in `go.opentelemetry.io/otel/sdk/log` no
longer includes the `Enabled` method. See the `FilterProcessor`
interface type added in `go.opentelemetry.io/otel/sdk/log/internal/x` to
continue providing this functionality. (#5692)
- The `SimpleProcessor` type in `go.opentelemetry.io/otel/sdk/log` is no
longer comparable. (#5693)
- The `BatchProcessor` type in `go.opentelemetry.io/otel/sdk/log` is no
longer comparable. (#5693)
### Fixed
- Correct comments for the priority of the `WithEndpoint` and
`WithEndpointURL` options and their corresponding environment variables
in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#5584)
- Pass the underlying error rather than a generic retry-able failure in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`,
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp` and
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#5541)
- Correct the `Tracer`, `Meter`, and `Logger` names used in
`go.opentelemetry.io/otel/example/dice`. (#5612)
- Correct the `Tracer` names used in
`go.opentelemetry.io/otel/example/namedtracer`. (#5612)
- Correct the `Tracer` name used in
`go.opentelemetry.io/otel/example/opencensus`. (#5612)
- Correct the `Tracer` and `Meter` names used in
`go.opentelemetry.io/otel/example/otel-collector`. (#5612)
- Correct the `Tracer` names used in
`go.opentelemetry.io/otel/example/passthrough`. (#5612)
- Correct the `Meter` name used in
`go.opentelemetry.io/otel/example/prometheus`. (#5612)
- Correct the `Tracer` names used in
`go.opentelemetry.io/otel/example/zipkin`. (#5612)
- Correct comments for the priority of the `WithEndpoint` and
`WithEndpointURL` options and their corresponding environment variables
in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`
and `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
(#5641)
- Correct comments for the priority of the `WithEndpoint` and
`WithEndpointURL` options and their corresponding environment variables
in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`.
(#5650)
- Stop percent encoding header environment variables in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`,
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`,
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc` and
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`
(#5705)
- Remove invalid environment variable header keys in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`,
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`,
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc` and
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`
(#5705)
### Removed
- The `Enabled` method of the `SimpleProcessor` in
`go.opentelemetry.io/otel/sdk/log` is removed. (#5692)
- The `Enabled` method of the `BatchProcessor` in
`go.opentelemetry.io/otel/sdk/log` is removed. (#5692)

Closes#5425
Our current log `Processor` interface contains more functionality than
the [OTel
spec](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/logs/sdk.md#logrecordprocessor-operations).
The additional functionality allows processors to report back to the API
if a Record should be constructed and emitted or not, which is quite
helpful[^1][^2][^3][^4][^5].
This removes the `Enabled` method from the `Processor` type. It adds
this functionality a new optional and experimental `FilterProcessor`
interface type. The logger and provider are updated to check for this
optional interface to be implemented with the configured processors and
uses them to back the `Logger.Enabled` method, preserving existing
functionality.
By making this change:
- The `Processor` interface is now compliant with the OTel spec and does
not contain any additional unspecified behavior.
- All `Processor` implementations are no longer required to implement an
`Enabled` method. The default, when they do not implement this method,
is to assume they are enabled.
### Benchmark
```terminal
goos: linux
goarch: amd64
pkg: go.opentelemetry.io/otel/sdk/log
cpu: Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz
│ old.txt │ new7.txt │
│ sec/op │ sec/op vs base │
LoggerEnabled-8 133.30n ± 3% 32.36n ± 3% -75.72% (p=0.000 n=10)
│ old.txt │ new7.txt │
│ B/op │ B/op vs base │
LoggerEnabled-8 0.000 ± 0% 0.000 ± 0% ~ (p=1.000 n=10) ¹
¹ all samples are equal
│ old.txt │ new7.txt │
│ allocs/op │ allocs/op vs base │
LoggerEnabled-8 0.000 ± 0% 0.000 ± 0% ~ (p=1.000 n=10) ¹
¹ all samples are equal
```
This is a significant performance improvement due to the `Record` no
longer being converted from the API version to the SDK version.

# Summary
This is to fix issue: #5642
The original logic skips copying TraceState when convert Spans between
OTel and OC.
This PR also updated the OTel TraceState to expose the Keys function for
the propagation purpose.
