OpenTelemetry Collector 0.107.0 release notes

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)

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)

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)

otelcol: Delete deprecated NewCommandMustSetProvider (#10778)
component: Removes the deprecated Host.GetFactory method. (#10771)
otelcoltest: The otelcol.LoadConfig method no longer sets the expandconverter. (#10510)
ocb: Collectors built with OCB will no longer include the expandconverter (#10510)
exporterhelper: Delete deprecated exporterhelper.ObsReport and exporterhelper.NewObsReport (#10779, #10592)

componentstatus: Adds new componentstatus module that will soon replace status content in component. (#10730)
connector/connectorprofiles: Allow handling profiles in connector. (#10703)
exporter/exporterprofiles: Allow handling profiles in exporter. (#10702)
processor/processorprofiles: Allow handling profiles in processor. (#10691)
receiver/receiverprofiles: Allow handling profiles in receiver. (#10690)

confmap: Check that providers have a correct scheme when building a confmap.Resolver. (#10786)
confighttp: Add NewDefaultCORSConfig function to initialize the default confighttp.CORSConfig (#9655)
