• Commit: 063230586884a4f4835e732ab1715b6903f848ec
• Prior Release: v2.4.1
• Prior Commit: 4942ab6ce15761b44b5ed46110c2d3439b009e81

This is an important but optional release for validators. This release adds new validator-side payment authorization. Validators who do not upgrade may be vulnerable to DOS attacks in the future when third party dispersers are onboarded.
