Changed

• To prevent sensitive information from leaking through query strings, the following instrumentations redact by default any value detected in query string components when building the url.query or the url.full attributes: OpenTelemetry.Instrumentation.Http, OpenTelemetry.Instrumentation.AspNetCore, OpenTelemetry.Instrumentation.AspNet. For example, ?key1=value1&key2=value2 becomes ?key1=Redacted&key2=Redacted. You can customize this behavior through the environment variables. See the instrumentation options table for details.
