docs(changelog): update changelog for v1.11.0

[worker-controller-auto-changelog]

⚠ Breaking Changes

• changelog: WithEndpointURL in

go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp
no longer appends the default signal path when an endpoint URL has no
path, making the behavior consistent with
go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp
and with setting the endpoint through
OTEL_EXPORTER_OTLP_METRICS_ENDPOINT. If the URL has no path
component, the root path (/) is used. Use
WithEndpointURL(url.JoinPath(endpoint,
"/v1/metrics")) to preserve the previous behavior. (<a

⚠️ Breaking Change: WithEndpointURL in

go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp
no longer appends the default signal path when an endpoint URL has no
path, making the behavior consistent with
go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp
and with setting the endpoint through
OTEL_EXPORTER_OTLP_TRACES_ENDPOINT. If the URL has no path
component, the root path (/) is used. Use
WithEndpointURL(url.JoinPath(endpoint,
"/v1/traces")) to preserve the previous behavior. (<a

href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/8538">#8538)

Deprecated

• Deprecate WithExportBufferSize in go.opentelemetry.io/otel/sdk/log. The option remains available for source compatibility but no longer affects behavior; BatchProcessor no longer maintains a separate export-request buffer. (href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/8620">#8620)

Removed

• ⚠️ Breaking Change: Remove Kind, Value, KeyValue, their constructors, and attribute conversion helpers from go.opentelemetry.io/otel/log. (href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/8490">#8490)
• ⚠️ Breaking Change: Remove the AttributeValueLengthLimit and AttributeCountLimit fields from RecordFactory in go.opentelemetry.io/otel/sdk/log/logtest; records produced by the factory now keep attribute limits disabled so test code can append exact attributes. (href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/8556">#8556)

Fixed

• Apply TLS certificates configured through environment variables to gRPC connections in

  go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc.

• Prevent panics in go.opentelemetry.io/otel/bridge/opentracing when OpenTracing baggage is propagated concurrently with Span.SetBaggageItem.
• Fix an off-by-one error in FixedSizeReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar that prevented the first exemplar from being sampled after the reservoir was filled. (href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/8309">#8309)
• Interpret HTTP Retry-After header values as seconds instead of nanoseconds when retrying OTLP HTTP exports in

  go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp,

  go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp,
  and

  go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp.

Changed

• HistogramReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar now uses a time-unbiased sampling algorithm for exemplars. (href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/8306">#8306)
• ⚠️ Breaking Change: Use go.opentelemetry.io/otel/attribute.Value and go.opentelemetry.io/otel/attribute.KeyValue for log bodies and attributes in go.opentelemetry.io/otel/log, go.opentelemetry.io/otel/log/logtest, go.opentelemetry.io/otel/sdk/log, and go.opentelemetry.io/otel/sdk/log/logtest. (href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/8490">#8490)
• Encode log bodies and attributes as go.opentelemetry.io/otel/attribute.Value JSON in go.opentelemetry.io/otel/exporters/stdout/stdoutlog. (href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/8490">#8490)
• Improve the performance of hashing BOOLSLICE, INT64SLICE, FLOAT64SLICE, and STRINGSLICE attribute values by avoiding reflection for short slices in go.opentelemetry.io/otel/attribute. (href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/8511">#8511)
