The next version of Virtuoso.
It's high-level design is described in TLA+.
Here's an email from Eric Verhulst, the head of the development team.

One of the results was that the code size was about 10x less than in [the previous version].](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:ulg2bzgrgs7ddjjlmhtegk3v/bafkreibxet54mro26fevjwofxyjqcbycyyajxirt6cqo7uz6uqa3ssreaq)
