SQLite Release 3.6.19 On 2009-10-14
- Added support for foreign key constraints.  Foreign key constraints
    are disabled by default.  Use the foreign_keys pragma to turn them on.
- Generalized the IS and IS NOT operators to take arbitrary expressions
    on their right-hand side.
- The TCL Interface has been enhanced to use the
    Non-Recursive Engine (NRE)
    interface to the TCL interpreter when linked against TCL 8.6 or later.
- Fix a bug introduced in 3.6.18 that can lead to a segfault when an
    attempt is made to write on a read-only database.
