The XRP Ledger is set to launch the fixCleanup3_1_3 upgrade on Wednesday, aimed at enhancing the network's efficiency and security. This upgrade requires validators and node operators to update their software to avoid disconnection. Key features of the upgrade include the automatic deletion of expired non-fungible token (NFT) offers, which currently clutter the ledger by remaining indefinitely if not accepted. Additionally, the upgrade addresses a bug that allowed unauthorized changes to permissioned domain settings, ensuring only approved accounts can modify these settings. It will also enforce trust-line limits on vault withdrawals, preventing users from sending more tokens than a receiving account can accept. Furthermore, improvements in loan accounting will ensure that all related records update accurately when a loan's status changes. The system will now return clearer error messages for loan overpayments, enhancing user clarity. This upgrade is crucial for maintaining the integrity and functionality of the XRP Ledger as it continues to facilitate multi-currency transactions.
