🛑 Breaking changes 🛑

• config: Remove already deprecates config.Service. (#6395)

• pdata: Change output of String() method of the following enum types to more a concise form: (#6251)

  • plog.SeverityNumber
  • ptrace.SpanKind
  • ptrace.StatusCode

• config: Remove already deprecates config.Config. (#6394)

• pdata: Remove deprecated code from pdata (#6417)

  • p[trace|metric|log]otlp.[Request|Response]
  • p[trace|metric|log]otlp.New[Request|Response]
  • p[trace|metric|log]otlp.NewRequestFrom[Traces|Metrics|Logs]
  • p[trace|metric|log]otlp.NewClient
  • p[trace|metric|log]New[JSON|Proto][Marshaler|Unmarshale]

• extension: Splitting ballast/zpages extension into their own modules (#6191)
  The import path for the extension modules can now be accessed directly:

  • go.opentelemetry.io/collector/extension/ballastextension
  • go.opentelemetry.io/collector/extension/zpagesextension

  If using one of these extensions, modify your Collector builder configuration to use gomod directly, such as:

  • gomod: go.opentelemetry.io/collector/extension/ballastextension v0.64.0

• processor: Splitting batch/memorylimiter processors into their own modules (#6188, #6192, #6193)
  The import path for the processor modules can now be access directly:

  • go.opentelemetry.io/collector/processor/batchprocessor
  • go.opentelemetry.io/collector/processor/memorylimiter

  If using this processor, modify your Collector builder configuration to use gomod directly, such as:

  • gomod: go.opentelemetry.io/collector/processor/batchprocessor v0.64.0

• otlpreceiver: Splitting otlp receiver into its own module (#6190)
  The import path for the OTLP receiver can now be access directly:

  • go.opentelemetry.io/collector/receiver/otlpreceiver

  If using this receiver, modify your Collector builder configuration to use gomod directly, such as:

  • gomod: go.opentelemetry.io/collector/receiver/otlpreceiver v0.64.0

• confmap: Remove unused public member sync.Mutex from confmap.Resolver. (#6489)
  This is an exception from the deprecation rule since this is not used anywhere and it is very unlikely that is used by external users.

• config: Deprecate multiple types and funcs in config package (#6422)

  • config.ComponentID => component.ID
  • config.Type => component.Type
  • config.DataType => component.DataType
  • config.[Traces|Metrics|Logs]DataType => component.DataType[Traces|Metrics|Logs]
  • config.Receiver => component.ReceiverConfig
  • config.UnmarshalReceiver => component.UnmarshalReceiverConfig
  • config.Processor => component.ProcessorConfig
  • config.UnmarshalProcessor => component.UnmarshalProcessorConfig
  • config.Exporter => component.ExporterConfig
  • config.UnmarshalExporter => component.UnmarshalExporterConfig
  • config.Extension => component.ExtensionConfig
  • config.UnmarshalExtension => component.UnmarshalExtensionConfig

• obsreport: deprecate obsreport.New[Receiver|Scraper|Processor|Exporter] in favor of obsreport.MustNew[Receiver|Scraper|Processor|Exporter] (#6458)

• config/configgrpc: Provide better helpers for configgrpc, consistent with confighttp (#6441)

  • Deprecate GRPCClientSettings.ToDialOptions in favor of GRPCClientSettings.ToClientConn.
  • Deprecate GRPCServerSettings.ToServerOption in favor of GRPCServerSettings.ToServer.
