I don’t normally like to spam release announcements, but I thought it’d be worth mentioning on the forum since 0.5.0 was a huge update for Diesel. The headline feature is that we now fully support SQLite in addition to PostgreSQL. You can of course still take full use of the features that are specific to PostgreSQL, and our type system will prevent you from accidentally trying to use them with SQLite, even if you’re using both backends in the same app!
You can see the full release announcement at https://github.com/sgrif/diesel/commit/44e40bc90a769d1539ff40afc034b514a3df5e75. We’ve also launched a new website, with a completely rewritten getting started guide. http://diesel.rs/
