=head1 SQLITE VERSION
DBD::SQLite is usually compiled with a bundled SQLite library
-(SQLite version S<3.12.0> as of this release) for consistency.
+(SQLite version S<3.12.2> as of this release) for consistency.
However, a different version of SQLite may sometimes be used for
some reasons like security, or some new experimental features.
