Exactly, it is the underlying OS API which was revamped in SQLite 3.5.
It doesn't hurt the on-disk format and it also usually doesn't affect
any SQLite based applications like Monotone -- at least as long as
one doesn't fiddle around with the underlying OS-related SQLite API
(which is not the case for Monotone). Even in OpenPKG I've not found any
application which was broken after the SQLite 3.4 to 3.5 upgrade.
