SQLite Release 3.5.0 On 2007 Sep 04 (3.5.0) alpha
Changes associated with this release include the following:
- Redesign the OS interface layer.  See
    34to35.html for details.
    *** Potentially incompatible change ***
- The sqlite3_release_memory(), sqlite3_soft_heap_limit(),
    and sqlite3_enable_shared_cache() interfaces now work cross all
    threads in the process, not just the single thread in which they
    are invoked.
    *** Potentially incompatible change ***
- Added the sqlite3_open_v2() interface.  
- Reimplemented the memory allocation subsystem and made it 
    replaceable at compile-time.
- Created a new mutex subsystem and made it replicable at
    compile-time.
- The same database connection may now be used simultaneously by
    separate threads.
