### Release Notes

<details>
<summary>open-telemetry/opentelemetry-collector (go.opentelemetry.io/collector/processor/processortest)</summary>

### [`v0.148.0`](https://github.com/open-telemetry/opentelemetry-collector/blob/HEAD/CHANGELOG.md#v1540v01480)

[Compare Source](open-telemetry/opentelemetry-collector@v0.147.0...v0.148.0)

##### ❗ Known Issues ❗

- `service`: The collector's internal Prometheus metrics endpoint (`:8888`) now emits OTel service labels with underscore
  names (`service_name`, `service_instance_id`, `service_version`) instead of dot-notation names (`service.name`,
  `service.instance.id`, `service.version`). Users scraping this endpoint with the Prometheus receiver will see these renamed
  labels in resource and datapoint attributes. As a workaround, add the following `metric_relabel_configs` to your scrape
  config in prometheus receiver:
  ```yaml
  metric_relabel_configs:
    - source_labels: [service_name]
      target_label: service.name
    - source_labels: [service_instance_id]
      target_label: service.instance.id
    - source_labels: [service_version]
      target_label: service.version
    - regex: service_name|service_instance_id|service_version
      action: labeldrop
  ```
  See [#&#8203;14814](open-telemetry/opentelemetry-collector#14814) for details and updates.

##### 🛑 Breaking changes 🛑

- `all`: Change metric units to be singular to match OTel specification, e.g. `{requests}` -> `{request}` ([#&#8203;14753](open-telemetry/opentelemetry-collector#14753))

##### 💡 Enhancements 💡

- `cmd/mdatagen`: Add deprecated\_type field to allow specifying an alias for component types. ([#&#8203;14718](open-telemetry/opentelemetry-collector#14718))
- `cmd/mdatagen`: Generate entity-scoped MetricsBuilder API that enforces entity-metric associations at compile time ([#&#8203;14659](open-telemetry/opentelemetry-collector#14659))
- `cmd/mdatagen`: Skip generating reaggregation config options for metrics that have no aggregatable attributes. ([#&#8203;14689](open-telemetry/opentelemetry-collector#14689))
- `pkg/service`: The internal status reporter no longer drops repeated Ok and RecoverableError statuses ([#&#8203;14282](open-telemetry/opentelemetry-collector#14282))
  Status events can now carry metadata and there's value in allowing them to be emitted despite the status value itself
  not changing.

##### 🧰 Bug fixes 🧰

- `cmd/builder`: Add `.exe` to output binary names when building for Windows targets. ([#&#8203;12591](open-telemetry/opentelemetry-collector#12591))

- `exporter/debug`: Add printing of metric metadata in detailed verbosity. ([#&#8203;14667](open-telemetry/opentelemetry-collector#14667))

- `exporter/otlp_grpc`: Prevent nil pointer panic when push methods are called before the OTLP exporter initializes its gRPC clients. ([#&#8203;14663](open-telemetry/opentelemetry-collector#14663))
  When the sending queue and retry are disabled, calling ConsumeTraces,
  ConsumeMetrics, ConsumeLogs, or ConsumeProfiles before the OTLP exporter
  initializes its gRPC clients could cause a nil pointer dereference panic.
  The push methods now return an error instead of panicking.

- `exporter/otlp_http`: Show the actual destination URL in error messages when request URL is modified by middleware. ([#&#8203;14673](open-telemetry/opentelemetry-collector#14673))
  Unwraps the `*url.Error` returned by `http.Client.Do()` to prevent misleading error logs when a middleware extension dynamically updates the endpoint.

- `pdata/pprofile`: Switch the dictionary of dictionary tables entries only once when merging profiles ([#&#8203;14709](open-telemetry/opentelemetry-collector#14709))
  For dictionary table data, we used to switch their dictionaries when doing
  the switch for the data that uses them.
  However, when an entry is associated with multiple other data (several
  samples can use the same stack), we would have been switching the
  dictionaries of the entry multiple times.

  We now switch dictionaries for dictionary table data only once, before
  switching the resource profiles.

### [`v1.53.0`](https://github.com/open-telemetry/opentelemetry-collector/blob/HEAD/CHANGELOG.md#v1530v01470)

##### 💡 Enhancements 💡

- `exporter/debug`: Output bucket counts for exponential histogram data points in normal verbosity. ([#&#8203;10463](open-telemetry/opentelemetry-collector#10463))
- `pkg/exporterhelper`: Add `metadata_keys` configuration to `sending_queue.batch.partition` to partition batches by client metadata ([#&#8203;14139](open-telemetry/opentelemetry-collector#14139))
  The `metadata_keys` configuration option is now available in the `sending_queue.batch.partition` section for all exporters.
  When specified, batches are partitioned based on the values of the listed metadata keys, allowing separate batching per metadata partition. This feature
  is automatically configured when using `exporterhelper.WithQueue()`.

##### 🧰 Bug fixes 🧰

- `cmd/builder`: Fix duplicate error output when CLI command execution fails in the builder tool. ([#&#8203;14436](open-telemetry/opentelemetry-collector#14436))

- `cmd/mdatagen`: Fix duplicate error output when CLI command execution fails in the mdatagen tool. ([#&#8203;14436](open-telemetry/opentelemetry-collector#14436))

- `cmd/mdatagen`: Fix semconv URL validation for metrics with underscores in their names ([#&#8203;14583](open-telemetry/opentelemetry-collector#14583))
  Metrics like `system.disk.io_time` now correctly validate against semantic convention URLs containing underscores in the anchor tag.

- `extension/memory_limiter`: Use ChainUnaryInterceptor instead of UnaryInterceptor to allow multiple interceptors. ([#&#8203;14634](open-telemetry/opentelemetry-collector#14634))
  If multiple extensions that use the UnaryInterceptor are set the binary panics at start time.

- `extension/memory_limiter`: Add support for streaming services. ([#&#8203;14634](open-telemetry/opentelemetry-collector#14634))

- `pkg/config/configmiddleware`: Add context.Context to HTTP middleware interface constructors. ([#&#8203;14523](open-telemetry/opentelemetry-collector#14523))
  This is a breaking API change for components that implement or use extensionmiddleware.

- `pkg/confmap`: Fix another issue where configs could fail to decode when using interpolated values in string fields. ([#&#8203;14034](open-telemetry/opentelemetry-collector#14034))
  For example, a resource attribute can be set via an environment variable to a string that is parseable as a number, e.g. `1234`.

  (A similar bug was fixed in a previous release: that one was triggered when the field was nested in a struct,
  whereas this one is triggered when the field internally has type "pointer to string" rather than "string".)

- `pkg/otelcol`: The featuregate subcommand now rejects extra positional arguments instead of silently ignoring them. ([#&#8203;14554](open-telemetry/opentelemetry-collector#14554))

- `pkg/queuebatch`: Fix data race in partition\_batcher where resetTimer() was called outside mutex, causing concurrent timer.Reset() calls and unpredictable batch flush timing under load. ([#&#8203;14491](open-telemetry/opentelemetry-collector#14491))

- `pkg/scraperhelper`: Log scrapers now emit log-appropriate receiver telemetry ([#&#8203;14654](open-telemetry/opentelemetry-collector#14654))
  Log scrapers previously emitted the same receiver telemetry as metric scrapers,
  such as the otelcol\_receiver\_accepted\_metric\_points metric (instead of otelcol\_receiver\_accepted\_log\_records),
  or spans named receiver/myreceiver/MetricsReceived (instead of receiver/myreceiver/LogsReceived).

  This did not affect scraper-specific spans and metrics.

- `processor/batch`: Fixes a bug where the batch processor would not copy `SchemaUrl` metadata from resource and scope containers during partial batch splits. ([#&#8203;12279](open-telemetry/opentelemetry-collector#12279), [#&#8203;14620](open-telemetry/opentelemetry-collector#14620))

### [`v1.51.0`](https://github.com/open-telemetry/opentelemetry-collector/blob/HEAD/CHANGELOG.md#v1510v01450)

##### 💡 Enhancements 💡

- `pkg/scraperhelper`: ScraperID has been added to the logs for metrics, logs, and profiles ([#&#8203;14461](open-telemetry/opentelemetry-collector#14461))

##### 🧰 Bug fixes 🧰

- `exporter/otlp_grpc`: Fix the OTLP exporter balancer to use round\_robin by default, as intended. ([#&#8203;14090](open-telemetry/opentelemetry-collector#14090))

- `pkg/config/configoptional`: Fix `Unmarshal` methods not being called when config is wrapped inside `Optional` ([#&#8203;14500](open-telemetry/opentelemetry-collector#14500))
  This bug notably manifested in the fact that the `sending_queue::batch::sizer` config for exporters
  stopped defaulting to `sending_queue::sizer`, which sometimes caused the wrong units to be used
  when configuring `sending_queue::batch::min_size` and `max_size`.

  As part of the fix, `xconfmap` exposes a new `xconfmap.WithForceUnmarshaler` option, to be used in the `Unmarshal` methods
  of wrapper types like `configoptional.Optional` to make sure the `Unmarshal` method of the inner type is called.

  The default behavior remains that calling `conf.Unmarshal` on the `confmap.Conf` passed as argument to an `Unmarshal`
  method will skip any top-level `Unmarshal` methods to avoid infinite recursion in standard use cases.

- `pkg/confmap`: Fix an issue where configs could fail to decode when using interpolated values in string fields. ([#&#8203;14413](open-telemetry/opentelemetry-collector#14413))
  For example, a header can be set via an environment variable to a string that is parseable as a number, e.g. `1234`

- `pkg/service`: Don't error on startup when process metrics are enabled on unsupported OSes (e.g. AIX) ([#&#8203;14307](open-telemetry/opentelemetry-collector#14307))
