Wasabi was developed by a company which closed its doors last year. Since then, a tiny group of volunteers took the responsibility to continue with the project and has been focused on guaranteeing the survival of the wallet. This means changing an originally centralized, trusted, client-server architecture to a standalone, trustless piece of software with decentralized services run by volunteers. In other words, the goal is still to completely redesign Wasabi's architecture to eliminate central points of failure and protect Wasabi users and volunteers.

Even though every release highlights user-oriented features such as Silent Payments, SLIP39, support for newer hardware wallets, and similar improvements, the most important changes are structural. These changes allow others to run coordinators, backend servers, or both. It also allows Wasabi to synchronize and operate without a central server by connecting to your own node.

The next goal for the team is to shut down the backend and let others host tiny indexers that users can connect to.

If you are interested, I explain all this a bit better in the Bitcoin Talk forum thread I posted: https://bitcointalk.org/index.php?topic=5476197.msg65272894#msg65272894
