<td><p>Version 3.3.0 adds support for descending indices and
uses a new encoding for boolean values that requires
less disk space. Version 3.3.0 can read and write database
files created by prior versions of SQLite. But prior versions
of SQLite will not be able to read or write databases created
by Version 3.3.0</p>
<p>If you need backwards and forwards capatibility, you can
compile with -DSQLITE_DEFAULT_FILE_FORMAT=1. Or at runtime
you can say "PRAGMA legacy_file_format=ON" prior to creating
a new database file</p>
<p>Once a database file is created, its format is fixed. So
a database file created by SQLite 3.2.8 and merely modified
by version 3.3.0 or later will retain the old format. Except,
the VACUUM command recreates the database so running VACUUM
on 3.3.0 or later will change the file format to the latest
edition.</p>
