🚩 Deprecations 🚩

• Deprecate go.opentelemetry.io/collector/service/featuregate in favor of go.opentelemetry.io/collector/featuregate. (#6094)
• Deprecate pmetric.OptionalType, unused enum type. (#6096)
• Deprecate ptrace.Span[Link]?.TraceStateStruct in favor of ptrace.Span[Link]?.TraceState (#6085)
• Deprecate pcommon.NewValueBytesEmpty in favor of pcommon.NewValueBytes that now has the same signature. (#6105)
• Deprecate pmetric.MetricDataType and related constants in favor of pmetric.MetricType. (#6127)
• Deprecate pmetric.Metric.DataType() in favor of pmetric.Metric.Type(). (#6127)
• Deprecate pmetric.NumberDataPoint.[Set]?[Int|Double]Val() in favor of pmetric.NumberDataPoint.[Set]?[Int|Double]Value(). (#6134)
• Deprecate pmetric.Exemplar.[Set]?[Int|Double]Val() in favor of pmetric.Exemplar.[Set]?[Int|Double]Value(). (#6134)
• Deprecate p[metric|log|trace]otlp.[Client|Server] in favor of p[metric|log|trace]otlp.GRPC[Client|Server] (#6165)
• Deprecate pdata Clone methods in favor of CopyTo for consistency with other pdata structs (#6164)
  • pmetric.Metrics.Clone is deprecated in favor of pmetric.Metrics.CopyTo
  • ptrace.Traces.Clone is deprecated in favor of pmetric.Traces.CopyTo
  • plog.Logs.Clone is deprecated in favor of plogs.Logs.CopyTo
• Rename all pcommon.Value getter/setter methods by removing Val suffix. (#6092)
  • Old methods with Val suffix are deprecated.
  • StringVal and SetStringVal are deprecated in favor of Str and SetStr to avoid implementing fmt.Stringer interface.
  • Therefore, ValueTypeString is deprecated in favour of ValueTypeStr for consistency.

💡 Enhancements 💡

• Add AppendEmpty and EnsureCapacity method to primitive pdata slices (#6060)
• Expose AsRaw and FromRaw pcommon.Value methods (#6090)
• Convert ValueTypeBytes attributes in logging exporter (#6153)
• service.name Resource attribute is added to Collector's own telemetry, defaults to the value of BuildInfo.Command and can be overridden in the config (#6152)
• Updated how telemetryInitializer is created so it's instanced per Collector instance rather than global to the process (#6138)
