+  [#3942](https://github.com/open-telemetry/opentelemetry-cpp/pull/3942)
+
+  * In TracerConfig(bool), MeterConfig(bool), and LoggerConfig(bool), the boolean parameter now represents `enabled` instead of `disabled`.
+  * User code calling these constructors explicitly must be adjusted to pass `false` to disable.
