### Release Notes

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

###
[`v1.56.0`](https://redirect.github.com/open-telemetry/opentelemetry-collector/blob/HEAD/CHANGELOG.md#v1560v01500)

##### 💡 Enhancements 💡

- `all`: Update semconv package from 1.38.0 to 1.40.0
([#&#8203;15095](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15095))
- `cmd/mdatagen`: Only allow the `ToVersion` feature flag attribute to
be set for the `Stable` and `Deprecated` stages.
([#&#8203;15040](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15040))
  To better match the feature flag README

(<https://github.com/open-telemetry/opentelemetry-collector/blob/main/featuregate/README.md#feature-lifecycle>).

##### 🧰 Bug fixes 🧰

- `exporter/debug`: Guard from out of bounds profiles dictionary indices
([#&#8203;14803](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14803))

- `pdata/pprofile`: create a copy when the input is marked as read-only
([#&#8203;15080](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15080))

- `pkg/otelcol`: Fix missing default values in unredacted print-config
command by introducing confmap.WithUnredacted MarshalOption.
([#&#8203;14750](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14750))
Resolves an issue where the unredacted mode output omitted all
default-valued options. By introducing a new MarshalOption to disable
redaction directly at the confmap encoding level, the unredacted mode
now preserves all component defaults natively without requiring
post-processing.

- `pkg/service`: Headers on the internal telemetry OTLP exporter are now
redacted when the configuration is marshaled
([#&#8203;14756](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14756))
