This release changes the "syncing" mode SQLite uses with on-disk files, by switching "synchronous" to OFF. The [SQLite docs](https://www.sqlite.org/pragma.html#pragma_synchronous) state that this risks database corruption in the event of a crash, but that's OK, as rqlite always blows away any SQLite database on startup and rebuilds it from the Raft log. Testing should this results in (at least) a 3x speed-up in write performance.
