According to U.Today, RippleX, Ripple's developer division, has called on node operators to upgrade to version 2.1.1. The latest version of the XRPL reference server implementation was made available a week ago and includes an important amendment designed to rectify a critical Automated Market Maker (AMM) vulnerability. If operators fail to update to the new version promptly, they risk being amendment blocked.
The AMM bug fix is set to be activated this Thursday, hence RippleX's push for node operators to carry out the upgrade. The AMM amendment was initially launched on the XRPL in May, with Ripple's Chief Technology Officer, David Schwartz, hailing it as a 'significant moment' for the XRPL due to its potential to broaden the decentralized finance (DeFi) ecosystem. The AMM mechanism enables the replacement of traditional order books with individual liquidity pools.
However, the new AMM feature did not function as smoothly as anticipated. A critical bug was identified in late March, which impeded the feature's intended functionality. Transactions could not be executed correctly due to an inconsistency in some AMM pools. XRPL users were advised not to use the feature while the RippleX team worked on resolving the issue. Community participants, such as Sologenic, promptly shut down deposit functionality. The 2.1.1 release now incorporates the fixAMMOverflowOffer amendment, which is intended to rectify the major bug.
