<li>Added the [unlikely()] and [likelihood()] SQL functions to be used
as hints to the query planner.
<li>Added the [soft_heap_limit pragma].
<li>Enhancements the query planner:
<ul>
<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>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.
<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

<li>Added the [unlikely()] and [likelihood()] SQL functions to be used
as hints to the query planner.
<li>Enhancements to the query planner:
<ul>
<li>Take into account the fact WHERE clause terms that cannot be used with indices
still probably reduce the number of output rows.
<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 the [soft_heap_limit pragma].
<li>Added support for [SQLITE_ENABLE_STAT4]

<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, 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
