The XRP Ledger network implemented the fixCleanup3_4_0 update on November 4. This enhancement addresses potential security vulnerabilities and strengthens functions related to automated market makers, asset management, transaction processing, and lending infrastructure. A critical component of this update was rectifying a potential security issue related to token issuance permissions. According to XRP Ledger documentation, the problem arose due to delegated authorities, enabling conditions under which certain accounts could erroneously create new tokens, though they were only meant to have burn permissions.
