Fixes#6986
This PR adds a `Clone()` method to the `log.Record` type.
The `Clone` method returns a copy of the record with no shared state,
allowing both the original and the clone to be modified independently.
This functionality mirrors the existing `sdk/log.Record.Clone()`
behavior and includes a corresponding unit test (`TestRecordClone`) to
ensure correctness.

### Added
- Add exponential histogram support in
`go.opentelemetry.io/otel/exporters/prometheus`. (#6421)
- The `go.opentelemetry.io/otel/semconv/v1.31.0` package.
The package contains semantic conventions from the `v1.31.0` version of

information on how to upgrade from

`ValuesGetter` interface in `go.opentelemetry.io/otel/propagation`.
(#5973)

(#6662)
- The `go.opentelemetry.io/otel/semconv/v1.32.0` package.
The package contains semantic conventions from the `v1.32.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.32.0/MIGRATION.md) for
information on how to upgrade from

(#6662)
### Changed
- ⚠️ Update `github.com/prometheus/client_golang` to `v1.21.1`, which
changes the `NameValidationScheme` to `UTF8Validation`.
This allows metrics names to keep original delimiters (e.g. `.`), rather
than replacing with underscores.
This can be reverted by setting
`github.com/prometheus/common/model.NameValidationScheme` to
`LegacyValidation` in `github.com/prometheus/common/model`. (#6433)

`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc` and
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#6392)
- Ensure the `noopSpan.tracerProvider` method is not inlined in
`go.opentelemetry.io/otel/trace` so the `go.opentelemetry.io/auto`
instrumentation can instrument non-recording spans. (#6456)
- Use a `sync.Pool` instead of allocating `metricdata.ResourceMetrics`
in `go.opentelemetry.io/otel/exporters/prometheus`. (#6472)

## Overview
This release is the last to support [Go 1.22].
The next release will require at least [Go 1.23].
### Added
- Add `ValueFromAttribute` and `KeyValueFromAttribute` in
`go.opentelemetry.io/otel/log`. (#6180)
- Add `EventName` and `SetEventName` to `Record` in
`go.opentelemetry.io/otel/log`. (#6187)
- Add `EventName` to `RecordFactory` in
`go.opentelemetry.io/otel/log/logtest`. (#6187)
- `AssertRecordEqual` in `go.opentelemetry.io/otel/log/logtest` checks
`Record.EventName`. (#6187)
- Add `EventName` and `SetEventName` to `Record` in
`go.opentelemetry.io/otel/sdk/log`. (#6193)
- Add `EventName` to `RecordFactory` in
`go.opentelemetry.io/otel/sdk/log/logtest`. (#6193)
- Emit `Record.EventName` field in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#6211)
- Emit `Record.EventName` field in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#6211)
- Emit `Record.EventName` field in
`go.opentelemetry.io/otel/exporters/stdout/stdoutlog` (#6210)
- The `go.opentelemetry.io/otel/semconv/v1.28.0` package.
The package contains semantic conventions from the `v1.28.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.28.0/MIGRATION.md) for
information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.27.0`(#6236)
- The `go.opentelemetry.io/otel/semconv/v1.30.0` package.
The package contains semantic conventions from the `v1.30.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.30.0/MIGRATION.md) for
information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.28.0`(#6240)
- Document the pitfalls of using `Resource` as a comparable type.
`Resource.Equal` and `Resource.Equivalent` should be used instead.
(#6272)
- Support [Go 1.24]. (#6304)
- Add `FilterProcessor` and `EnabledParameters` in
`go.opentelemetry.io/otel/sdk/log`.
It replaces
`go.opentelemetry.io/otel/sdk/log/internal/x.FilterProcessor`.
Compared to previous version it additionally gives the possibility to
filter by resource and instrumentation scope. (#6317)
### Changed
- Update `github.com/prometheus/common` to v0.62.0., which changes the
`NameValidationScheme` to `NoEscaping`. This allows metrics names to
keep original delimiters (e.g. `.`), rather than replacing with
underscores. This is controlled by the `Content-Type` header, or can be
reverted by setting `NameValidationScheme` to `LegacyValidation` in
`github.com/prometheus/common/model`. (#6198)
### Fixes
- Eliminate goroutine leak for the processor returned by
`NewSimpleSpanProcessor` when `Shutdown` is called and the passed `ctx`
is canceled and `SpanExporter.Shutdown` has not returned. (#6368)
- Eliminate goroutine leak for the processor returned by
`NewBatchSpanProcessor` when `ForceFlush` is called and the passed `ctx`
is canceled and `SpanExporter.Export` has not returned. (#6369)

## Overview
### Changed
- Remove the notices from `Logger` to make the whole Logs API
user-facing in `go.opentelemetry.io/otel/log`. (#6167)
### Fixed
- Relax minimum Go version to 1.22.0 in various modules. (#6073)
- The `Type` name logged for the
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc` client
is corrected from `otlphttpgrpc` to `otlptracegrpc`. (#6143)
- The `Type` name logged for the
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlphttpgrpc` client
is corrected from `otlphttphttp` to `otlptracehttp`. (#6143)
### Added
- Add `Reset` method to `SpanRecorder` in
`go.opentelemetry.io/otel/sdk/trace/tracetest`. (#5994)
- Add `EnabledInstrument` interface in
`go.opentelemetry.io/otel/sdk/metric/internal/x`. This is an
experimental interface that is implemented by synchronous instruments
provided by `go.opentelemetry.io/otel/sdk/metric`. Users can use it to
avoid performing computationally expensive operations when recording
measurements. 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. (#6016)
### Changed
- The default global API now supports full auto-instrumentation from the
`go.opentelemetry.io/auto` package. See that package for more
information. (#5920)
- Propagate non-retryable error messages to client in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#5929)
- Propagate non-retryable error messages to client in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#5929)
- Propagate non-retryable error messages to client in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
(#5929)
- Performance improvements for attribute value `AsStringSlice`,
`AsFloat64Slice`, `AsInt64Slice`, `AsBoolSlice`. (#6011)
- Change `EnabledParameters` to have a `Severity` field instead of a
getter and setter in `go.opentelemetry.io/otel/log`. (#6009)
### Fixed
- Fix inconsistent request body closing in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#5954)
- Fix inconsistent request body closing in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#5954)
- Fix inconsistent request body closing in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
(#5954)
- Fix invalid exemplar keys in
`go.opentelemetry.io/otel/exporters/prometheus`. (#5995)
- Fix attribute value truncation in
`go.opentelemetry.io/otel/sdk/trace`. (#5997)
- Fix attribute value truncation in `go.opentelemetry.io/otel/sdk/log`.
(#6032)
When the auto-instrumentation attaches to a process using the global
TracerProvider, and there has not been a delegate set, create a span
from the go.opentelemetry.io/auto/sdk package so the OTel Go
auto-instrumentation can instrument the application by default.

keeps the metadata already present in the context when `WithHeaders` is
used. (#5911)
