    modified columns are associated with foreign keys.
<li>Added the [SQLITE_MINIMUM_FILE_DESCRIPTOR] compile-time option
<li>Added the win32-longpath VFS on windows, permitting filenames up to 32K
    characters in length.
<li>The [Date And Time Functions] are enhanced so that the current time
    (ex: julianday('now')) is always the same for multiple function invocations
    within the same [sqlite3_step()] call.

<li>Added the [tointeger()] and [toreal()] SQL functions.
<li>[FTS4] queries are better able to make use of docid<$limit constraints to
    limit the amount of I/O required.
<li>The [VACUUM] command packs the database about 1% tighter.
<li>The sqlite3_analyzer utility program is updated to provide better descriptions
    and to compute a more accurate estimate for "Non-sequential pages"
<li>Refactor the implementation of PRAGMA statements to improve parsing performance.
<li>The directory used to hold temporary files on unix can now be set using
