+* For issue [#569](Add include_stability config into semconv_grouped_attributes): added `stable_only` boolean flag as a parameter for
+  `semconv_signal`, `semconv_grouped_attributes`, and other `semconv_*` JQ semconv helpers. When `stable_only` is set to `true`,
+  corresponding helper function returns stable conventions only. If the flag is not set or set to false, stability filtering does not apply.
+  It's recommended to use `stable_only` flag instead of `exclude_stability` parameter.
