## v1.26.0/v0.120.0

### 🛑 Breaking changes 🛑

- `configauth`: Remove NewDefaultAuthentication (#12223)

  Calls to `NewConfigProvider` will now return `*ConfigProvider`,
  but will otherwise work the same as before.

  - 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)
- `confighttp`: Add `ToClientOption` type and add it to signature of `ToClient` method. (#12353)
  - This has no use for now, it may be used in the future.

## v0.106.0

### 🛑 Breaking changes 🛑

- `configauth`: removing deprecated methods GetServerAuthenticatorContext and GetClientAuthenticatorContext (#9808)
- `connector,exporter,receiver,extension,processor`: Remove deprecated funcs/structs (#10423)
  Remove the following funcs & structs:
  - connector.CreateSettings -> connector.Settings
  - connectortest.NewNopCreateSettings -> connectortest.NewNopSettings
  - exporter.CreateSettings -> exporter.Settings
  - exportertest.NewNopCreateSettings -> exportertest.NewNopSettings
  - extension.CreateSettings -> extension.Settings
  - extensiontest.NewNopCreateSettings -> extensiontest.NewNopSettings
  - processor.CreateSettings -> processor.Settings
  - processortest.NewNopCreateSettings -> processortest.NewNopSettings
  - receiver.CreateSettings -> receiver.Settings
  - receivertest.NewNopCreateSettings -> receivertest.NewNopSettings
  
- `component/componenttest`: Add optional ...attribute.KeyValue argument to TestTelemetry.CheckExporterMetricGauge. (#10593)
- `confighttp`: Auth data type signature has changed (#4806)
  As part of the linked PR, the `auth` attribute was moved from `configauth.Authentication` 
  to a new `AuthConfig`, which contains a `configauth.Authentication`. For end-users, this
  is a non-breaking change. For users of the API, create a new AuthConfig using the
  `configauth.Authentication` instance that was being used before.
  
- `mdatagen`: Remove WithAttributes option from the telemetry builder constructor. (#10608)
  Attribute sets for async instruments now can be set as options to callback setters and async instruments initializers.
  This allows each async instrument to have its own attribute set.
  
- `service/extensions`: Adds `Options` to `extensions.New`. (#10728)
  This is only a breaking change if you are depending on `extensions.New`'s signature. Calls to `extensions.New` are not broken.

### 🧰 Bug fixes 🧰

- `confmap`: Fix wrong expansion of environment variables escaped with `$$`, e.g. `$${ENV_VAR}` and `$$ENV_VAR`. (#10713)
  This change fixes the issue where environment variables escaped with $$ were expanded. 
  The collector now converts `$${ENV_VAR}` to `${ENV_VAR}` and `$$ENV_VAR` to `$ENV_VAR` without further expansion.
