C++20 introduced a breaking change where u8 string literals changed from const char arrays to const char8_t arrays, causing previously compatible code to fail compilation.

Microsoft's disc-to-digital feature, which converts physical Xbox game discs to digital copies, stems from a decision made 15 years ago to uniquely identify discs. The capability is now part of Xbox's game preservation efforts and gives Microsoft an advantage over Sony, who cannot easily replicate the feature without similar disc metadata. The move reflects the industry's broader shift toward all-digital game distribution.
