🛑 Breaking changes 🛑

• configauth: Removes deprecated configauth.Authentication and extensionauthtest.NewErrorClient (#12992)
  The following have been removed:
  • configauth.Authentication use configauth.Config instead
  • extensionauthtest.NewErrorClient use extensionauthtest.NewErr instead

💡 Enhancements 💡

• service: Replace go.opentelemetry.io/collector/semconv usage with go.opentelemetry.io/otel/semconv (#12991)

• confmap: Update the behavior of the confmap.enableMergeAppendOption feature gate to merge only component lists. (#12926)

• service: Add item count metrics defined in Pipeline Component Telemetry RFC (#12812)
  See Pipeline Component Telemetry RFC for more details:

  • otelcol.receiver.produced.items
  • otelcol.processor.consumed.items
  • otelcol.processor.produced.items
  • otelcol.connector.consumed.items
  • otelcol.connector.produced.items
  • otelcol.exporter.consumed.items

• tls: Add trusted platform module (TPM) support to TLS authentication. (#12801)
  Now the TLS allows the use of TPM for loading private keys (e.g. in TSS2 format).

🧰 Bug fixes 🧰

• exporterhelper: Add validation error for batch config if min_size is greater than queue_size. (#12948)

• telemetry: Allocate less memory per component when OTLP exporting of logs is disabled (#13014)

• confmap: Use reflect.DeepEqual to avoid panic when confmap.enableMergeAppendOption feature gate is enabled. (#12932)

• internal telemetry: Add resource attributes from telemetry.resource to the logger (#12582)
  Resource attributes from telemetry.resource were not added to the internal
  console logs.

  Now, they are added to the logger as part of the "resource" field.

• confighttp and configcompression: Fix handling of snappy content-encoding in a backwards-compatible way (#10584, #12825)
  The collector used the Snappy compression type of "framed" to handle the HTTP
  content-encoding "snappy". However, this encoding is typically used to indicate
  the "block" compression variant of "snappy". This change allows the collector to:

  • When receiving a request with encoding 'snappy', the server endpoints will peek
    at the first bytes of the payload to determine if it is "framed" or "block" snappy,
    and will decompress accordingly. This is a backwards-compatible change.

  If the feature-gate "confighttp.framedSnappy" is enabled, you'll see new behavior for both client and server:

  • Client compression type "snappy" will now compress to the "block" variant of snappy
    instead of "framed". Client compression type "x-snappy-framed" will now compress to the "framed" variant of snappy.
  • Servers will accept both "snappy" and "x-snappy-framed" as valid content-encodings.

• tlsconfig: Disable TPM tests on MacOS/Darwin (#12964)
