Libstdc++ headers have been updated with comments referencing Library Working Group (LWG) defect reports from 2023 that affect pre-C++23 features. These comments provide context for specific implementation choices or behaviors related to issues like LWG3887, LWG3953, LWG3892, and LWG3655, aiding developers in understanding the standard’s evolution.
