Dat uses an append-only feed that’s inspired by Certificate Transparency to create auditable change logs in file archives. We use this to deliver Web applications securely in Beaker.
A big part of this release was about improving the UX. We’re thinking very specifically about how we want Beaker, as a product, to work. We took inspiration from a lot of different products, including CodePen, GitHub, and even iTunes.
The other major half of this release was making fixes to the Dat protocol. We’ve improved our debugging techniques, and found some key issues that we’ve patched.
