I'm a little confused. They've supported offline for some time.

Even published a very cool article last July about all the (considerable) challenges one runs into when going after making wasm-sqlite work: https://www.notion.com/blog/how-we-sped-up-notion-in-the-bro...

The article you posted doesn't mention "offline" at all. We use SQLite as a cache in the browser when available and in iOS/Android/desktop apps, but we didn't have any guarantee that a page you want offline is actually available offline.

It would "mostly work" offline before, but you could have cases where some blocks in a page aged out of the LRU, or they changed online in a way that invalidated the page but new content wasn't downloaded. When that happens we show a "go online to view" error instead of risking you viewing/editing a known-incorrect local snapshot of the page.

With "available offline", we now proactively download and keep up-to-date the content you want available offline. It will either work, or show an explicit error if things go wrong in the sync process. No more guesswork.
