Mon Sep 22 07:36:30 UTC 2025 - Johannes Kastl <opensuse_buildservice@ojkastl.de>
- update to 0.135.0:
The full changelog for this release is here:
https://github.com/open-telemetry/opentelemetry-collector/releases/tag/v0.135.0
* Enhancements
- exporterhelper: Add new exporter_queue_batch_send_size and
exporter_queue_batch_send_size_bytes metrics, showing the
size of telemetry batches from the exporter. (#12894)
- update to 0.134.0:
The full changelog for this release is here:
https://github.com/open-telemetry/opentelemetry-collector/releases/tag/v0.134.0
* Enhancements
- pdata: Add custom grpc/encoding that replaces proto and calls
into the custom marshal/unmarshal logic in pdata. (#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) 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)
* Bug fixes
- pdata: Correctly parse OTLP payloads containing non-packed
repeated primitive fields (#13727, #13730) This bug prevented
the Collector from ingesting most Histogram,
ExponentialHistogram, and Profile payloads.
- update to 0.133.0:
The full changelog for this release is here:
https://github.com/open-telemetry/opentelemetry-collector/releases/tag/v0.133.0
* Breaking changes
- all: Increase minimum Go version to 1.24 (#13627)
* Enhancements
- otlphttpexporter: Add profiles_endpoint configuration option
to allow custom endpoint for profiles data export (#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) 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)
- receiverhelper: New feature flag to make receiverhelper
distinguish internal vs. downstream errors using new
otelcol_receiver_failed_x and otelcol_receiver_requests
metrics (#12207, #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)
- pdata: Fix unnecessary allocation of a new state when adding
new values to pcommon.Map (#13634)
- service: Implement refcounting for pipeline data owned
memory. (#13631) This feature is protected by
--featuregate=+pdata.useProtoPooling.
- service: Add a debug-level log message when a consumer
returns an error. (#13357)
- xpdata: Optimize xpdata/context for persistent queue when
only one value for key (#13636)
- otlpreceiver: Log the listening addresses of the receiver,
rather than the configured endpoints. (#13654)
- pdata: Use the newly added proto marshaler/unmarshaler for
the official proto Marshaler/Unmarshaler (#13637) If any
problems observed with this consider to disable the
featuregate --feature-gates=-pdata.useCustomProtoEncoding
- configtls: Enable X25519MLKEM768 as per
draft-ietf-tls-ecdhe-mlkem (#13670)
* Bug fixes
- exporterhelper: Prevent uncontrolled goroutines in batcher
due to a incorrect worker pool behaviour. (#13689)
- service: Ensure the insecure configuration is accounted for
when normalizing the endpoint. (#13691)
- configoptional: Allow validating nested types (#13579)
- configoptional.Optional now implements xconfmap.Validator
- batchprocessor: Fix UB in batch processor when trying to read
bytes size after adding request to pipeline (#13698) This bug
only happens id detailed metrics are enabled and also an
async (sending queue enabled) exporter that mutates data is
configure.
- update to 0.132.0:
The full changelog for this release is here:
https://github.com/open-telemetry/opentelemetry-collector/releases/tag/v0.132.0
* Breaking changes
- componentstatus: Change the signature of the
componentstatus.NewEvent to accept multiple options. (#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)
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)
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)
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:
service:
telemetry:
metrics:
level: detailed
views:
- selector:
meter_name: "go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc"
stream:
attribute_keys:
excluded: ["net.sock.peer.addr", "net.sock.peer.port", "net.sock.peer.name"]
- selector:
meter_name: "go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp"
stream:
attribute_keys:
excluded: ["net.host.name", "net.host.port"]
Note that this requires setting
service::telemetry::metrics::level: detailed. If you have a
strong use case for using views in combination with a
different level, please show your interest in #10769.
* Enhancements
- pdata: Generate Logs/Traces/Metrics/Profiles and
p[log|trace|metric|profile]ExportResponse with pdatagen.
(#13597) This change brings consistency on how these structs
are written and remove JSON marshaling/unmarshaling hand
written logic.
- confighttp: Add option to configure ForceAttemptHTTP2 to
support HTTP/1 specific transport settings. (#13426)
- pdata: Avoid unnecessary buffer copy when JSON marshal fails.
(#13598)
- cmd/mdatagen: Use a custom host implementation for lifecycle
tests (#13589) Use a custom noop host implementation that
implements all non-deprecated, publicly-accessible interfaces
implemented by the Collector service.
- processorhelper: Add processor internal duration metric.
(#13231)
- pdata: Improve RemoveIf for slices to not reference anymore
the removed memory (#13522)
* Bug fixes
- pdata: Fix null pointer access when copying into a slice with
larger cap but smaller len. (#13523)
- confighttp: Fix middleware configuration field name from
"middleware" to "middlewares" for consistency with configgrpc
(#13444)
- memorylimiterextension, memorylimiterprocessor: Memory
limiter extension and processor shutdown don't throw an error
if the component was not started first. (#9687) The
components would throw an error if they were shut down before
being started. With this change, they will no longer return
an error, conforming to the lifecycle of components expected.
- confighttp: Reuse zstd Reader objects (#11824)
-------------------------------------------------------------------
Mon Aug 4 07:27:29 UTC 2025 - Johannes Kastl <opensuse_buildservice@ojkastl.de>
- update to 0.131.0:
* Breaking changes
- confighttp: Move confighttp.framedSnappy feature gate to
beta. (#10584)
* Enhancements
- exporter/debug: Move to alpha stability except profiles
(#13487)
- exporterhelper: Enable exporter.PersistRequestContext feature
gate by default. (#13437)
Request context is now preserved by default when using
persistent queues.
Note that Auth extensions context is not propagated through
the persistent queue.
- pdata: Use pdatagen to generate marshalJSON without using
gogo proto jsonpb. (#13450)
- otlpreceiver: Remove usage of gogo proto which uses
reflect.Value.MethodByName. Removes one source of disabling
DCE. (#12747)
- exporterhelper: Fix metrics split logic to consider metrics
description into the size. (#13418)
- service: New pipeline instrumentation now differentiates
internal failures from downstream errors (#13234)
With the telemetry.newPipelineTelemetry feature gate enabled,
the "received" and "produced" metrics related to a component
now distinguish between two types of errors:
- "outcome = failure" indicates that the component returned
an internal error;
- "outcome = refused" indicates that the component
successfully emitted data, but returned an error coming
from a downstream component processing that data.
- pdata: Remove usage of text/template from pdata, improves
DCE. (#12747)
- architecture: New Tier 3 platform riscv64 allowing the
collector to be built and distributed for this platform.
(#13462)
* Bug fixes
- exporterhelper: Prevents the exporter for being stuck when
telemetry data is bigger than batch.max_size (#12893)
- mdatagen: Fix import paths for mdatagen component (#13069)
- otlpreceiver: Error handler correctly fallbacks to content
type (#13414)
- pdata/pprofiles: Fix profiles JSON unmarshal logic for
originalPayload. The bytes have to be base64 encoded.
(#13483)
- xpdata: Fix unmarshaling JSON for entities, add e2e tests to
avoid this in the future. (#13480)
- service: Downgrade dependency of prometheus exporter in OTel
Go SDK (#13429)
This fixes the bug where collector's internal metrics are
emitted with an unexpected suffix in their names when users
configure the service::telemetry::metrics::readers with
Prometheus
- service: Revert Default internal metrics config now enables
otel_scope_ labels (#12939, #13344)
Reverting change temporarily due to prometheus exporter
downgrade. This unfortunately re-introduces the bug that
instrumentation scope attributes cause errors in Prometheus
exporter. See
http://github.com/open-telemetry/opentelemetry-collector/issues/12939
for details.
- builder: Remove undocumented handling of DIST_* environment
variables replacements (#13335)
API Changelog
* Breaking changes
- configgrpc: Update optional fields to use
configoptional.Optional field for optional values. (#13252,
#13364)
Specifically, the following fields have been updated to
configoptional:
- KeepaliveServerConfig.ServerParameters
(KeepaliveServerParameters type)
- KeepaliveServerConfig.EnforcementPolicy
(KeepaliveEnforcementPolicy type)
- xexporterhelper: Remove deprecated NewProfilesExporter
function from xexporterhelper package (#13391)
* Enhancements
- consumererror: Add new "Downstream" error marker (#13234)
This new error wrapper type indicates that the error returned
by a component's Consume method is not an internal failure of
the component, but instead was passed through from another
component further downstream. This is used internally by the
new pipeline instrumentation feature to determine the outcome
of a component call. This wrapper is not intended to be used
by components directly.
- pdata/pprofile: Introduce Equal method on the Function type
(#13222)
- pdata/pprofile: Introduce Equal method on the Link type
(#13223)
- pdata/pprofile: Add new helper method SetFunction to set a
new function on a line. (#13222)
- pdata/pprofile: Add new helper method SetLink to set a new
link on a sample. (#13223)
- pdata/pprofile: Add new helper method SetString to set or
retrieve the index of a value in the StringTable. (#13225)

- update to 0.130.0:
End User Changelog
* Known Issues
Due to a bug in the internal telemetry Prometheus exporter, if
you are configuring an internal telemetry 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 internal
telemetry Prometheus exporter config
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 internal telemetry
Prometheus exporter for exporting internal metrics you are
unaffected.
This issue has been fixed in v0.130.1. If you are using the
Collector builder, please use the builder v0.130.1 to fix this
issue.
* Breaking changes
- exporter/otlp: Remove deprecated batcher config from OTLP,
use queuebatch (#13339)
* Enhancements
- exporterhelper: Enable items and bytes sizers for persistent
queue (#12881)
- exporterhelper: Refactor persistent storage size backup to
always record it. (#12890)
- exporterhelper: Add support to configure a different Sizer
for the batcher than the queue (#13313)
- yaml: Replaced sigs.k8s.io/yaml with go.yaml.in/yaml for
improved support and long-term maintainability. (#13308)
* Bug fixes
- exporterhelper: Fix exporter.PersistRequestContext feature
gate (#13342)
- exporterhelper: Preserve all metrics metadata when batch
splitting. (#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, #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.

Mon Aug 4 07:00:05 UTC 2025 - Johannes Kastl <opensuse_buildservice@ojkastl.de>
- update to 0.129.0:
End User Changelog
* Breaking changes
- exporterhelper: Remove deprecated sending_queue::blocking
options, use sending_queue::block_on_overflow. (#13211)
* Enhancements
- mdatagen: Taught mdatagen to print the go list stderr output
on failures, and to run go list where the metadata file is.
(#13205)
- service: Support setting sampler and limits under
service::telemetry::traces (#13201) This allows users to
enable sampling and set span limits on internal Collector
traces using the OpenTelemetry SDK declarative configuration.
- pdata/pprofile: Add new helper methods FromLocationIndices
and PutLocation to read and modify the content of locations.
(#13150)
- exporterhelper: Preserve request span context and client
information in the persistent queue. (#11740, #13220, #13232)
It allows internal collector spans and client information to
propagate through the persistent queue used by 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).
* Bug fixes
- pdata: Fix copying of optional fields when the source is
unset. (#13268)
- service: Only allocate one set of internal log sampling
counters (#13014) The case where logs are only exported to
stdout was fixed in v0.126.0; this new fix also covers the
case where logs are exported through OTLP.
API Changelog

support marshaling and unmarshaling of request context.
(#13188)
* Enhancements
- pdata/pprofile: Introduce Equal method on the Mapping type
(#13197)
- configoptional: Make unmarshaling into None[T] work the same
as unmarshaling into (*T)(nil). (#13168)
- configoptional: Add a confmap.Marshaler implementation for
configoptional.Optional (#13196)
- pdata/pprofile: Introduce Equal methods on the Line and
Location types (#13150)
- pdata/pprofile: Add new helper method SetMapping to set a new
mapping on a location. (#13197)

- update to 0.128.0:
End User Changelog
* Breaking changes
- service/telemetry: Mark
"telemetry.disableAddressFieldForInternalTelemetry" as stable
(#13152)
* Enhancements
- confighttp: Update the HTTP server span naming to use the
HTTP method and route pattern instead of the path. (#12468)
The HTTP server span name will now be formatted as
<http.request.method> <http.route>. If a route pattern is
not available, it will fall back to <http.request.method>.
- service: Use configured loggers to log errors as soon as it
is available (#13081)
- service: Remove stabilized featuregate
useOtelWithSDKConfigurationForInternalTelemetry (#13152)
* Bug fixes
- telemetry: Add generated resource attributes to the printed
log messages. (#13110) If service.name, service.version, or
service.instance.id are not specified in the config, they
will be generated automatically. This change ensures that
these attributes are also included in the printed log
messages.
- mdatagen: Fix generation when there are no events in the
metadata. (#13123)
- confmap: Do not panic on assigning nil maps to non-nil maps
(#13117)
- pdata: Fix event_name skipped when unmarshalling LogRecord
from JSON (#13127) API Changelog

configuration sections in the OTLP receiver. Remove Unmarshal
method. (#13119)
- confighttp,configgrpc: Rename ClientConfig.TLSSetting and
ServerConfig.TLSSetting to ClientConfig.TLS and
ServerConfig.TLS. (#13115)
- pdata/pprofile: Upgrade the OTLP protobuf definitions to
version 1.7.0 (#13075) Note that the batcher is temporarily a
noop.
- pipeline: Remove deprecated MustNewID[WithName] (#13139)
* New components
- configoptional: Add a new configoptional module to support
optional configuration fields. (#12981)
* Enhancements
- pdata: Introduce MoveAndAppendTo methods to the generated
primitive slices (#13074)
- pdata: Upgrade the OTLP protobuf definitions to version 1.7.0
(#13075)
* Bug fixes
- confmap: Correctly distinguish between nil and empty map
values on the ToStringMap method (#13161) This means that
ToStringMap() method can now return a nil map if the original
value was nil. If you were not doing so already, make sure
to check for nil before writing to the map to avoid panics.
- confighttp: Make the NewDefaultServerConfig function return a
nil TLS config by default. (#13129)
- The previous default was a TLS config with no certificates,
which would fail at runtime.

Sun Jun 8 07:34:10 UTC 2025 - Johannes Kastl <opensuse_buildservice@ojkastl.de>
- new package opentelemetry-collector: OpenTelemetry collector
distribution that contains all the components from the
OpenTelemetry Collector repository and a small selection of
components tied to open source projects from the OpenTelemetry
Collector Contrib repository.
This distribution is considered "classic" and is no longer
accepting new components outside of components from the Core
repo.
