API Changelog

🛑 Breaking changes 🛑

• configauth: Remove NewDefaultAuthentication (#12223)
  The value returned by this function will always cause an error on startup.
  In configgrpc.Client/ServerConfig.Auth, nil should be used instead to disable authentication.

• otelcol: Make the ConfigProvider interface a struct (#12297)
  Calls to NewConfigProvider will now return *ConfigProvider,
  but will otherwise work the same as before.

• extension: Remove extension.Settings.ModuleInfo (#12296)

  • The functionality is now available as an optional, hidden interface on service's implementation of the Host

• component: Remove deprecated field component.TelemetrySettings.MetricsLevel. (#11061)

  Components that were manually using metadata.NewOutgoingContext as a workaround no longer need to
  do so, unless they are overwriting or adding header keys.

• configgrpc: Set Auth to nil in NewDefaultClientConfig/NewDefaultServerConfig (#12223)
  The value that was used previously would always cause an error on startup.

• confighttp: confighttp.ToServer now sets ErrorLog with a default logger backed by Zap (#11820)

v1.20.0/v0.114.0

💡 Enhancements 💡

• cmd/builder: Allow for replacing of local Providers and Converters when building custom collector with ocb. (#11649)
  Use the property path under gomod to replace an go module with a local folder in
  builder-config.yaml. Ex:

  providers:
    - gomod: module.url/my/custom/provider v1.2.3
      path: /path/to/local/provider
  

• cmd/builder: Allow configuring confmap.Converter components in ocb. (#11582)
  If no converters are specified, there will be no converters added.
  Currently, the only published converter is expandconverter which is
  deprecated as of v0.107.0, but can still be added for testing purposes.

  To configure a custom converter, make sure your converter implements the converter
  interface and is published as a go module (or replaced locally if not published).
  You may then use the converters key in your OCB build manifest with a list of
  Go modules (and replaces as necessary) to include your converter.

  Please note that converters are order-dependent. The confmap will apply converters
  in order of which they are listed in your manifest if there is more than one.

• all: shorten time period before removing an unmaintained component from 6 months to 3 months (#11664)

🧰 Bug fixes 🧰

• all: Updates dialer timeout section documentation in confignet README (#11685)
• scraperhelper: If the scraper shuts down, do not scrape first. (#11632)
  When the scraper is shutting down, it currently will scrape at least once.
  With this change, upon receiving a shutdown order, the receiver's scraperhelper will exit immediately.

🐛 Known bugs 🐛

• The ocb binary has an identified bug caused by the fact that some of the providers have been marked stable and the default providers in the ocb binary still use the unstable version. In order to fix this explicitly add the default providers in your otel builder config, if not already configured:

providers:
  - gomod: go.opentelemetry.io/collector/confmap/provider/envprovider v1.17.0
  - gomod: go.opentelemetry.io/collector/confmap/provider/fileprovider v1.17.0
  - gomod: go.opentelemetry.io/collector/confmap/provider/httpprovider v1.17.0
  - gomod: go.opentelemetry.io/collector/confmap/provider/httpsprovider v1.17.0
  - gomod: go.opentelemetry.io/collector/confmap/provider/yamlprovider v1.17.0

This release removes the logging exporter. See #11337 to migrate to the debug exporter.

🛑 Breaking changes 🛑

• service/telemetry: Change default metrics address to "localhost:8888" instead of ":8888" (#11251)
  This behavior can be disabled by disabling the feature gate telemetry.UseLocalHostAsDefaultMetricsAddress.
• loggingexporter: Removed the deprecated logging exporter. Use the debug exporter instead. (#11037).
  You can read issue #11337 for migration instructions.

🚩 Deprecations 🚩

• service/telemetry: Deprecate service::telemetry::metrics::address in favor of service::telemetry::metrics::readers. (#11205)
• processorhelper: Deprecate BuildProcessorMetricName as it's no longer needed since introduction of mdatagen (#11302)

💡 Enhancements 💡

• ocb: create docker images for OCB, per open-telemetry/opentelemetry-collector-releases#671 (#5712)
  Adds standard Docker images for OCB to Dockerhub and GitHub, see hub.docker.com/r/otel/opentelemetry-collector-builder
• confighttp: Snappy compression to lazy read for memory efficiency (#11177)
• httpsprovider: Mark the httpsprovider as stable. (#11191)
• httpprovider: Mark the httpprovider as stable. (#11191)
• yamlprovider: Mark the yamlprovider as stable. (#11192)
• confmap: Allow using any YAML structure as a string when loading configuration including time.Time formats (#10659)
  Previously, fields with time.Time formats could not be used as strings in configurations

🧰 Bug fixes 🧰

• processorhelper: Fix data race condition, concurrent writes to the err variable, causes UB (Undefined Behavior) (#11350)

API Changes

🛑 Breaking changes 🛑

• service/telemetry: Change default metrics address to "localhost:8888" instead of ":8888" (#11251)
  This behavior can be disabled by disabling the feature gate 'telemetry.UseLocalHostAsDefaultMetricsAddress'.

• componentprofiles: Removed deprecated DataTypeProfiles. Use SignalProfiles instead. (#11312)

• configgrpc: Replace ToClientConn and ToServer with ToClientConnWithOptions and ToServerWithOptions. (#11271, #9480)
  ClientConfig.ToClientConn and ServerConfig.ToServer were deprecated in v0.110.0 in favor of
  ClientConfig.ToClientConnWithOptions and ServerConfig.ToServerWithOptions which use a more
  flexible option type. The original functions are now removed, and the new ones are renamed to the
  old names. The WithOptions names are kept as deprecated aliases for now.

• exporterhelper: Removed deprecated QueueTimeout/TimeoutSettings aliases in favor of QueueConfig/TimeoutConfig. (#11264, #6767)
  NewDefaultQueueSettings and NewDefaultTimeoutSettings have been similarly renamed.

• exporterqueue: Remove deprecated Settings.DataType. Use Settings.Signal instead. (#11305)

• exportertest: Remove deprecated CheckConsumeContractParams.DataType. Use CheckConsumeContractParams.Signal instead. (#11305)

• component: Removed deprecated ErrDataTypeIsNotSupported, DataType, DataTypeTraces, DataTypeMetrics, and DataTypeLogs. Use pipeline.ErrSignalNotSupported, pipeline.Signal, pipeline.SignalTraces, pipeline.SignalMetrics, and pipeline.SignalLogs instead. (#11253)

• pdata/pprofile: Replace slices of values to slices of pointers for the Mapping, Location, Line, Function, AttributeUnit, Link, Value, Sample and Labels attributes. (#11339)

• receivertest: Remove deprecated CheckConsumeContractParams.DataType. Use CheckConsumeContractParams.Signal instead. (#11304)

• scraperhelper: Remove deprecated function NewScraperWithComponentType. (#11294)

• processorhelper: Remove deprecated funcs form processorhelper.ObsReport (#11289)
  The "otelcol_processor_dropped_log_records", "otelcol_processor_dropped_log_records" | and "otelcol_processor_dropped_spans" metrics are complete removed, before they were always record with 0 values.
