🛑 Breaking changes 🛑

• service: Batch processor telemetry is no longer emitted at "basic" verbosity level (#7890)
  According to the guidelines, basic-level telemetry should be reserved for core Collector APIs.
  Components such as the batch processor should emit telemetry starting from the "normal" level
  (which is also the default level).

  Migration: If your Collector telemetry was set to level: basic and you want to keep seeing
  batch processor-related metrics, consider switching to level: normal instead.

💡 Enhancements 💡

• service: Add service.AllowNoPipelines feature gate to allow starting the Collector without pipelines. (#12613)
  This can be used to start with only extensions.

• mdatagen: Delete generated_status.go if the component type doesn't require it. (#12346)

• componenttest: Improve config struct mapstructure field tag checks (#12590)
  remain tags and omitempty tags without a custom field name will now pass validation.

• service: include component id/type in start error (#10426)

• mdatagen: Add deprecation date and migration guide fields as part of component metadata (#12359)

• confmap: Introduce a new feature flag to allow for merging lists instead of discarding the existing ones. (#8394, #8754, #10370)
  You can enable this option via the command line by running following command:
  otelcol --config=main.yaml --config=extra_config.yaml --feature-gates=-confmap.enableMergeAppendOption

• zpagesextension: Add expvar handler to zpages extension. (#11081)

🧰 Bug fixes 🧰

• confmap: Maintain nil values when marshaling or unmarshaling nil slices (#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.

• service: do not attempt to register process metrics if they are disabled (#12098)

💡 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.

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.
