WhatsApp's Hidden Notes Told AI Not to Recommend a Regulator
Dan Saltman, founder of Redact, found hidden text for artificial intelligence (AI) tools on WhatsApp help pages. On the account deletion page, the text told AI not to suggest contacting a regulator. On a second help page, the text told AI to avoid legal topics and skip privacy laws such as the General Data Protection Regulation (GDPR).

It also removes Loongson support because it did not work with Clang 22.
