v1.21.0/v0.115.0

🛑 Breaking changes 🛑

• otelcol: Change all logged timestamps to ISO8601. (#10543)
  This makes log timestamps human-readable (as opposed to epoch seconds in
  scientific notation), but may break users trying to parse logged lines in the
  old format.
• pdata/pprofile: Upgrade pdata to opentelemetry-proto v1.4.0 (#11722)

🚩 Deprecations 🚩

• scraperhelper: Deprecate all Scraper helpers in scraperhelper (#11732)
  Deprecate ScrapeFunc, ScraperOption, WithStart, WithShutdown in favor of equivalent funcs in scraper package.

💡 Enhancements 💡

• exporterqueue: Introduce a feature gate exporter.UsePullingBasedExporterQueueBatcher to use the new pulling model in exporter queue batching. (#8122, #10368)
  If both queuing and batching is enabled for exporter, we now use a pulling model instead of a
  pushing model. num_consumer in queue configuration is now used to specify the maximum number of
  concurrent workers that are sending out the request.

• service: label metrics as alpha to communicate their stability (#11729)

• consumer: Mark consumer as stable. (#9046)

• service: Add support for ca certificates in telemetry metrics otlp grpc exporter (#11633)
  Before this change the Certificate value in config was silently ignored.

🧰 Bug fixes 🧰

• service: ensure OTLP emitted logs respect severity (#11718)
• featuregate: Fix an unfriendly display message runtime error when featuregate is used to display command line usage. (#11651)
• profiles: Fix iteration over scope profiles while counting the samples. (#11688)

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.

End User Changelog

🐛 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.

End User Changelog

v1.13.0/v0.107.0

🛑 Breaking changes 🛑

• service: Remove OpenCensus bridge completely, mark feature gate as stable. (#10414)
• confmap: Set the confmap.unifyEnvVarExpansion feature gate to Stable. Expansion of $FOO env vars is no longer supported. Use ${FOO} or ${env:FOO} instead. (#10508)
• service: Remove otelcol from Prometheus configuration. This means that any metric that isn't explicitly prefixed with otelcol_ no longer have that prefix. (#9759)

💡 Enhancements 💡

• mdatagen: export ScopeName in internal/metadata package (#10845)
  This can be used by components that need to set their scope name manually. Will save component owners from having to store a variable, which may diverge from the scope name used by the component for emitting its own telemetry.

• semconv: Add v1.26.0 semantic conventions package (#10249, #10829)

• mdatagen: Expose a setting on tests::host to set up your own host initialization code (#10765)
  Some receivers require a host that has additional capabilities such as exposing exporters.
  For those, we can expose a setting that allows them to place a different host in the generated code.

• confmap: Allow using any YAML structure as a string when loading configuration. (#10800)
  Previous to this change, slices could not be used as strings in configuration.

• ocb: migrate build and release of ocb binaries to opentelemetry-collector-releases repository (#10710)
  ocb binaries will now be released under open-telemetry/opentelemetry-collector-releases tagged as "cmd/builder/vX.XXX.X"

• semconv: Add semantic conventions version v1.27.0 (#10837)

• client: Mark module as stable. (#10775)

🧰 Bug fixes 🧰

• configtelemetry: Add 10s read header timeout on the configtelemetry Prometheus HTTP server. (#5699)

• service: Allow users to disable the tracer provider via the feature gate service.noopTracerProvider (#10858)
  The service is returning an instance of a SDK tracer provider regardless of whether there were any processors configured causing resources to be consumed unnecessarily.

• processorhelper: Fix processor metrics not being reported initially with 0 values. (#10855)

• service: Implement the temporality_preference setting for internal telemetry exported via OTLP (#10745)

• configauth: Fix unmarshaling of authentication in HTTP servers. (#10750)

• confmap: If loading an invalid YAML string through a provider, use it verbatim instead of erroring out. (#10759)
  This makes the ${env:ENV} syntax closer to how ${ENV} worked before unifying syntaxes.

• component: Allow component names of up to 1024 characters in length. (#10816)

• confmap: Remove original string representation if invalid. (#10787)
