The rippled 0.80.0 release introduces several enhancements that improve the reliability, scalability and security of the XRP Ledger.
Highlights of this release include:
The SortedDirectories amendment, which allows the entries stored within a page to be sorted, and corrects a technical flaw that could, in some edge cases, prevent an empty intermediate page from being deleted.
Changes to the UNL and quorum rules
Use a fixed size UNL if the total listed validators are below threshold
Ensure a quorum of 0 cannot be configured
Set a quorum to provide Byzantine fault tolerance until a threshold of total validators is exceeded, at which time the quorum is 80>#/li###
