##### 🛑 Breaking changes 🛑
- `pkg/config/confighttp`: Use configoptional.Optional for
confighttp.ClientConfig.Cookies field
([#​14021](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14021))
##### 💡 Enhancements 💡
- `pkg/config/confighttp`: Setting `compression_algorithms` to an empty
list now disables automatic decompression, ignoring Content-Encoding
([#​14131](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14131))
- `pkg/service`: Update semantic conventions from internal telemetry to
v1.37.0
([#​14232](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14232))

[`v0.140.0`](https://redirect.github.com/open-telemetry/opentelemetry-collector/blob/HEAD/CHANGELOG.md#v1460v01400)
[Compare
Source](https://redirect.github.com/open-telemetry/opentelemetry-collector/compare/v0.139.0...v0.140.0)
##### 💡 Enhancements 💡
- `cmd/mdatagen`: `metadata.yaml` now supports an optional `entities`
section to organize resource attributes into logical entities with
identity and description attributes
([#​14051](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14051))
When entities are defined, mdatagen generates
`AssociateWith{EntityType}()` methods on ResourceBuilder
that associate resources with entity types using the entity refs API.
The entities section is backward
compatible - existing metadata.yaml files without entities continue to
work as before.
- `cmd/mdatagen`: Add semconv reference for metrics
([#​13920](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13920))
- `connector/forward`: Add support for Profiles to Profiles
([#​14092](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14092))
- `exporter/debug`: Disable sending queue by default
([#​14138](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14138))
The recently added sending queue configuration in Debug exporter was
enabled by default and had a problematic default size of 1.
This change disables the sending queue by default.
Users can enable and configure the sending queue if needed.
- `pkg/config/configoptional`: Mark `configoptional.AddEnabledField` as
beta
([#​14021](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14021))
- `pkg/otelcol`: This feature has been improved and tested;
secure-by-default redacts configopaque values
([#​12369](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12369))
##### 🧰 Bug fixes 🧰
- `all`: Ensure service service.instance.id is the same for all the
signals when it is autogenerated.

##### 🛑 Breaking changes 🛑
- `cmd/mdatagen`: Make stability.level a required field for metrics
([#​14070](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14070))
- `cmd/mdatagen`: Replace `optional` field with `requirement_level`
field for attributes in metadata schema
([#​13913](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13913))
The `optional` boolean field for attributes has been replaced with a
`requirement_level` field that accepts enum values: `required`,
`conditionally_required`, `recommended`, or `opt_in`.
- `required`: attribute is always included and cannot be excluded
- `conditionally_required`: attribute is included by default when
certain conditions are met (replaces `optional: true`)
- `recommended`: attribute is included by default but can be disabled
via configuration (replaces `optional: false`)
- `opt_in`: attribute is not included unless explicitly enabled in user
config
When `requirement_level` is not specified, it defaults to `recommended`.
- `pdata/pprofile`: Remove deprecated `PutAttribute` helper method
([#​14082](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14082))
- `pdata/pprofile`: Remove deprecated `PutLocation` helper method
([#​14082](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14082))

configuration to enable it.
([#​10028](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/10028))
- `pkg/config/configgrpc`: Errors of type status.Status returned from an
Authenticator extension are being propagated as is to the upstream
client.
([#​14005](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14005))
- `pkg/config/configoptional`: Adds new `configoptional.AddEnabledField`
feature gate that allows users to explicitly disable a
`configoptional.Optional` through a new `enabled` field.
([#​14021](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14021))
- `pkg/exporterhelper`: Replace usage of gogo proto for persistent queue
metadata
([#​14079](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14079))
- `pkg/pdata`: Remove usage of gogo proto and generate the structs with
pdatagen
([#​14078](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14078))
##### 🧰 Bug fixes 🧰
- `exporter/debug`: add queue configuration

##### 🛑 Breaking changes 🛑
- `all`: Remove deprecated type `TracesConfig`
([#​14036](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14036))
- `pkg/exporterhelper`: Add default values for `sending_queue::batch`
configuration.
([#​13766](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13766))
Setting `sending_queue::batch` to an empty value now results in the same
setup as the default batch processor configuration.
- `all`: Add unified print-config command with mode support (redacted,
unredacted), json support (unstable), and validation support.
([#​11775](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/11775))
This replaces the `print-initial-config` command. See the `service`
package README for more details. The original command name
`print-initial-config` remains an alias, to be retired with the feature
flag.
##### 💡 Enhancements 💡
- `all`: Add `keep_alives_enabled` option to ServerConfig to control
HTTP keep-alives for all components that create an HTTP server.
([#​13783](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13783))
- `pkg/otelcol`: Avoid unnecessary mutex in collector logs, replace by
atomic pointer
([#​14008](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14008))
- `cmd/mdatagen`: Add lint/ordering validation for metadata.yaml
([#​13781](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13781))
- `pdata/xpdata`: Refactor JSON marshaling and unmarshaling to use
`pcommon.Value` instead of `AnyValue`.
([#​13837](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13837))
- `pkg/exporterhelper`: Expose `MergeCtx` in exporterhelper's queue
batch settings\`
([#​13742](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13742))
##### 🧰 Bug fixes 🧰
- `all`: Fix zstd decoder data corruption due to decoder pooling for all
components that create an HTTP server.
([#​13954](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13954))
- `pkg/otelcol`: Remove UB when taking internal logs and move them to
the final zapcore.Core
([#​14009](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14009))
This can happen because of a race on accessing `logsTaken`.
- `pkg/confmap`: Fix a potential race condition in confmap by closing
the providers first.

##### 💡 Enhancements 💡
- `cmd/mdatagen`: Improve validation for resource attribute `enabled`
field in metadata files
([#​12722](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12722))
Resource attributes now require an explicit `enabled` field in
metadata.yaml files, while regular attributes
are prohibited from having this field. This improves validation and
prevents configuration errors.
- `all`: Changelog entries will now have their component field checked
against a list of valid components.
([#​13924](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13924))
This will ensure a more standardized changelog format which makes it
easier to parse.
- `pkg/pdata`: Mark featuregate pdata.useCustomProtoEncoding as stable

##### 💡 Enhancements 💡
- `pdata`: Add custom grpc/encoding that replaces proto and calls into
the custom marshal/unmarshal logic in pdata.
([#​13631](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13631))
This change should not affect other gRPC calls since it fallbacks to the
default grpc/proto encoding if requests are not pdata/otlp requests.
- `pdata`: Avoid copying the pcommon.Map when same origin
([#​13731](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13731))
This is a very large improvement if using OTTL with map functions since
it will avoid a map copy.
- `exporterhelper`: Respect `num_consumers` when batching and
partitioning are enabled.
([#​13607](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13607))
##### 🧰 Bug fixes 🧰
- `pdata`: Correctly parse OTLP payloads containing non-packed repeated
primitive fields
([#​13727](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13727),
[#​13730](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13730))
This bug prevented the Collector from ingesting most Histogram,
ExponentialHistogram,
and Profile payloads.

([#​13627](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13627))
##### 💡 Enhancements 💡
- `otlphttpexporter`: Add `profiles_endpoint` configuration option to
allow custom endpoint for profiles data export
([#​13504](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13504))
The `profiles_endpoint` configuration follows the same pattern as
`traces_endpoint`, `metrics_endpoint`, and `logs_endpoint`.
When specified, profiles data will be sent to the custom URL instead of
the default `{endpoint}/v1development/profiles`.
- `pdata`: Add support for local memory pooling for data objects.
([#​13678](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13678))
This is still an early experimental (alpha) feature. Do not recommended
to be used production. To enable use
"--featuregate=+pdata.useProtoPooling"
- `pdata`: Optimize CopyTo messages to avoid any copy when same source
and destination
([#​13680](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13680))

internal vs. downstream errors using new `otelcol_receiver_failed_x` and
`otelcol_receiver_requests` metrics
([#​12207](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12207),
[#​12802](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12802))
This is a breaking change for the semantics of the
otelcol\_receiver\_refused\_metric\_points,
otelcol\_receiver\_refused\_log\_records and
otelcol\_receiver\_refused\_spans metrics.
These new metrics and semantics are enabled through the
`receiverhelper.newReceiverMetrics` feature gate.
- `debugexporter`: Add support for entity references in debug exporter
output
([#​13324](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13324))
- `pdata`: Fix unnecessary allocation of a new state when adding new
values to pcommon.Map
([#​13634](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13634))

([#​13631](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13631))
This feature is protected by `--featuregate=+pdata.useProtoPooling`.
- `service`: Add a debug-level log message when a consumer returns an
error.
([#​13357](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13357))

- `pdata`: Use the newly added proto marshaler/unmarshaler for the
official proto Marshaler/Unmarshaler
([#​13637](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13637))
If any problems observed with this consider to disable the featuregate
`--feature-gates=-pdata.useCustomProtoEncoding`
<!-- cspell:ignore MLKEM mlkem -->
- `configtls`: Enable X25519MLKEM768 as per draft-ietf-tls-ecdhe-mlkem
([#​13670](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13670))
##### 🧰 Bug fixes 🧰
- `exporterhelper`: Prevent uncontrolled goroutines in batcher due to a
incorrect worker pool behaviour.
([#​13689](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13689))

- `batchprocessor`: Fix UB in batch processor when trying to read bytes
size after adding request to pipeline
([#​13698](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13698))
This bug only happens id detailed metrics are enabled and also an async
(sending queue enabled) exporter that mutates data is configure.

##### 🛑 Breaking changes 🛑
- `componentstatus`: Change the signature of the
componentstatus.NewEvent to accept multiple options.
([#​13210](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13210))
Changes the signature of the component.NewEvent to accept multiple
EventBuilderOption,
like the new WithAttributes constructor.
##### 🚩 Deprecations 🚩
- `service`: move service.noopTraceProvider feature gate to deprecated
stage
([#​13492](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13492))
The functionality of the feature gate is available via configuration
with the following telemetry settings:
```
service:
telemetry:
traces:
level: none
```
- `mdatagen`: Remove the deletion of
`generated_component_telemetry_test.go`.
([#​12067](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12067))
This file used to be generated by mdatagen. Starting with 0.122.0, the
code deletes that file.
It is no longer necessary to delete the file, as code has had time to
upgrade to mdatagen and delete the file.
- `service`: The `telemetry.disableHighCardinalityMetrics` feature gate
is deprecated
([#​13537](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13537))
The feature gate is now deprecated since metric views can be configured.
The feature gate will be removed in v0.134.0.
The metric attributes removed by this feature gate are no longer emitted
by the Collector by default, but if needed, you can achieve the same
functionality by configuring the following metric views:
```yaml
service:
telemetry:
metrics:
level: detailed
views:
- selector:
meter_name:
"go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc"
stream:

##### ❗ Known Issues ❗
- Due to a
[bug](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7039)
in the prometheus exporter, if you are configuring a prometheus
exporter, the collector's internal metrics will be emitted with an
unexpected suffix in its name. For example, the metric
`otelcol_exporter_sent_spans__spans__total` instead of
`otelcol_exporter_sent_spans_total`. The workaround is to manually
configure `without_units: true` in your prometheus exporter config
```yaml
service:
telemetry:
metrics:
readers:
- pull:
exporter:
prometheus:
host: 0.0.0.0
port: 8888
without_units: true
```
If you are using the collector's default Prometheus exporter for
exporting internal metrics you are unaffected.

([#​13342](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13342))
- `exporterhelper`: Preserve all metrics metadata when batch splitting.
([#​13236](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13236))
Previously, when large batches of metrics were processed, the splitting
logic in `metric_batch.go` could
cause the `name` field of some metrics to disappear. This fix ensures
that all metric fields are
properly preserved when `metricRequest` objects are split.
- `service`: Default internal metrics config now enables `otel_scope_`
labels
([#​12939](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12939),
[#​13344](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13344))
By default, the Collector exports its internal metrics using a
Prometheus
exporter from the opentelemetry-go repository. With this change, the
Collector
no longer sets "without\_scope\_info" to true in its configuration.
This means that all exported metrics will have `otel_scope_name`,
`otel_scope_schema_url`, and `otel_scope_version` labels corresponding
to the
instrumentation scope metadata for that metric.
This notably prevents an error when multiple metrics are only
distinguished
by their instrumentation scopes and end up aliased during export.
If this is not desired behavior, a Prometheus exporter can be explicitly
configured with this option enabled.

It allows internal collector spans and client information to propagate

the exporters. The same way as it's done for the in-memory queue.
Currently, it is behind the exporter.PersistRequestContext feature gate,
which can be enabled by adding
`--feature-gates=exporter.PersistRequestContext` to the collector
command line. An exporter buffer stored by
a previous version of the collector (or by a collector with the feature
gate disabled) can be read by a newer
collector with the feature enabled. However, the reverse is not
supported: a buffer stored by a newer collector with
the feature enabled cannot be read by an older collector (or by a
collector with the feature gate disabled).

[#​12825](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/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.

[#​12933](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12933))
The "off" state of this feature gate introduced a regression, where the
Collector's internal logs were missing component attributes. See issue
[#​12870](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12870)
for more details on this bug.
On the other hand, the "on" state introduced an issue with the
Collector's default internal metrics, because the Prometheus exporter
does not currently support instrumentation scope attributes.
To solve both of these issues, this change turns on the new scope
attributes for logs and traces by default regardless of the feature
gate.
However, the new scope attributes for metrics stay locked behind the
feature gate, and will remain off by default until the Prometheus
exporter is updated to support scope attributes.
Please understand that enabling the `telemetry.newPipelineTelemetry`
feature gate may break the export of Collector metrics through,
depending on your configuration.
Having a `batch` processor in multiple pipelines is a known trigger for
this.
This comes with a breaking change, where internal logs exported through
OTLP will now use instrumentation scope attributes to identify the
source component instead of log attributes.
This does not affect the Collector's stderr output. See the changelog
for v0.123.0 for a more detailed description of the gate's effects.

batching is enabled.
([#​12244](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12244))
- `exporterhelper`: Reject elements larger than the queue capacity
([#​12847](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12847))
- `mdatagen`: Add time and plog package imports
([#​12907](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12907))
- `confmap`: Maintain nil values when marshaling or unmarshaling nil
slices
([#​11882](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/11882))
Previously, nil slices were converted to empty lists, which are
semantically different
than a nil slice. This change makes this conversion more consistent when
encoding
or decoding config, and these values are now maintained.

###
[`v0.123.0`](https://redirect.github.com/open-telemetry/opentelemetry-collector/blob/HEAD/CHANGELOG.md#v1290v01230)
[Compare
Source](https://redirect.github.com/open-telemetry/opentelemetry-collector/compare/v0.122.1...v0.123.0)
##### ❗ Known Issues ❗
- This version increases memory usage by \~0.5 MB per component in the
pipelines because a separate Zap Core logger is
initialized for each component. The issue is partially fixed in v0.126.0
for users who write logs to stdout, but do
not export logs via OTLP. See
[#​13014](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13014)
for more details.
##### 🛑 Breaking changes 🛑
- `service/telemetry`: Mark
`telemetry.disableAddressFieldForInternalTelemetry` as beta, usage of
deprecated service::telemetry::address are ignored
([#​25115](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/25115))
To restore the previous behavior disable
`telemetry.disableAddressFieldForInternalTelemetry` feature gate.
- `exporterbatch`: Remove deprecated fields `min_size_items` and
`max_size_items` from batch config.
([#​12684](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12684))
##### 🚩 Deprecations 🚩
- `otlpexporter`: Mark BatcherConfig as deprecated, use
`sending_queue::batch` instead
([#​12726](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12726))
- `exporterhelper`: Deprecate `blocking` in favor of
`block_on_overflow`.
([#​12710](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12710))
- `exporterhelper`: Deprecate configuring exporter batching separately.
Use `sending_queue::batch` instead.
([#​12772](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12772))
Moving the batching configuration to `sending_queue::batch` requires
setting `sending_queue::sizer` to `items`
which means that `sending_queue::queue_size` needs to be also increased
by the average batch size number (roughly
x5000 for the default batching configuration).
See
<https://github.com/open-telemetry/opentelemetry-collector/tree/main/exporter/exporterhelper#configuration>
##### 💡 Enhancements 💡
- `exporterhelper`: Add support to configure batching in the sending
queue.
([#​12746](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12746))
- `exporterhelper`: Add support for wait\_for\_result, remove
disabled\_queue
([#​12742](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/12742))
This has a side effect for users of the experimental BatchConfig with
the queue disabled, since not this is | uses only NumCPU() consumers.
- `exporterhelper`: Allow exporter memory queue to use different type of
sizers.
