+  - Methods on `*Config` (package `apis/v1beta1`) converted to standalone functions in `internal/otelconfig`, now taking `*v1beta1.Config` as the first parameter:
+      - GetEnabledComponents, GetReceiverPorts, GetExporterPorts, GetExtensionPorts, GetReceiverAndExporterPorts, GetAllPorts, GetEnvironmentVariables, GetAllRbacRules, ApplyDefaults, GetLivenessProbe, GetReadinessProbe, GetStartupProbe, Yaml, NullObjects
+  - Methods on `*Service` converted to functions in `internal/otelconfig`:
+      - MetricsEndpoint, GetTelemetry
+      - ApplyDefaults → renamed to ServiceApplyDefaults
+  - Method on `*Telemetry` converted to function:
+      - ToAnyConfig → renamed to TelemetryToAnyConfig
+  -  Functions moved from `apis/v1beta1` to `internal/metrics` with renames:
+      - BootstrapMetrics → Bootstrap
+      - NewMetrics(prv, ctx, cl) → New(ctx, prv, cl) (parameter reorder: ctx now first)
+  - Types moved out of `apis/v1beta1`:
+      - MetricsConfig, Telemetry → internal/otelconfig
+      - Metrics → internal/metrics
