<li>Take into account WHERE clause terms that cannot be used with indices.
<li>Estimate the sizes of table and index rows and use the smallest applicable B-Tree
    for full scans and "count(*)" operations.
</ul>
<li>Added support for [SQLITE_ENABLE_STAT4]
<li>Added support for "sz=NNN" parameters at the end of sqlite_stat1.stat fields
    used to specify the average length in bytes for table and index rows.
<li>Changed the [index_list pragma] so that it shows the estimated size of index
    rows and so that it shows a new row for the PRIMARY KEY index that gives the
    estimated size of table rows.
<li>Avoid running foreign-key constraint checks on an UPDATE if none of the
    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.
<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.

    using this pragma.</p>
