🧰 Bug fixes 🧰

• service: Fix running collector as a windows service. (#6433)

🛑 Breaking changes 🛑

• pdata: JSON marshaler emits enums as ints per spec requirements. This may be a breaking change if receivers were not confirming with the spec. (#6338)

• confmap: Remove deprecated confmap.Conf.UnmarshalExact API in 0.62.0 (#6315)

• pdata: Remove API deprecated in 0.62.0 (#6314)

  • Remove deprecated pcommon.NewValueString
  • Remove deprecated pcommon.Map.PutString
  • Remove deprecated plog.SeverityNumberUndefined
  • Remove deprecated p[metric|log|trace]otlp.RegisterServer

  • Remove deprecated pmetric.[New]?ValueAtQuantileSlice
  • Remove deprecated ptrace.[New]?SpanStatus

• exporter: Splitting otlp, otlphttp and logging exporters into their own modules (#6343) The import path for these exporters can now be access directly:

  • go.opentelemetry.io/collector/exporter/loggingexporter
  • go.opentelemetry.io/collector/exporter/otlpexporter
  • go.opentelemetry.io/collector/exporter/otlphttpexporter

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

  • gomod: go.opentelemetry.io/collector/exporter/otlpexporter v0.63.0

🚩 Deprecations 🚩

• overwritepropertiesconverter: Deprecate overwritepropertiesconverter, only used by non builder distributions. (#6294)

  • Deprecate p[trace|metric|log]otlp.NewRequestFrom[Traces|Metrics|Logs] in favor of p[trace|metric|log]otlp.NewExportRequestFrom[Traces|Metrics|Logs]

• service/telemetry: Move logging and tracing initialization to service/telemetry (#5564)
• confmap: Fail fast when a resolver has URIs with unsupported schemes. (#6274)
• service: Use the same prometheus.Registry for the OpenCensus and OpenTelemetry Go prometheus exporters to act as a bridge for internal telemetry (#6297)

🧰 Bug fixes 🧰

• pdata: Because of wrong deprecation/rename in proto, services still send the fake 1000 proto id. See https://github.com/open-telemetry/opentelemetry-proto/issues/431 (#6342)
• confmap: When a sub-config implements Unmarshaler, do not reinitialized it unless necessary. (#6392)
• pdata: Enable enums as ints for otlp messages, switch to jsoniter for responses. (#6345)
• collector: Fixed collector service not cleaning up if it failed during Start (#6352)

• Fix support for new line in config URI location. (#6306)
