<li> Disallow the use of [window functions] in the recursive part of
     a CTE. Ticket [https://sqlite.org/src/info/e8275b415a2f03bee|e8275b415a2f03bee]

<li> Strengthen defenses against deliberately corrupted database files.
<li> Fix a problem in the query planner that results when a row-value expression
     is used with a PRIMARY KEY with redundant columns.  Ticket
     [https://sqlite.org/src/info/1a84668dcfdebaf12415d|1a84668dcfdebaf12415d]
<li> Fix the query planner so that it works correctly for IS NOT NULL operators
     in the ON clause of a LEFT JOIN with the SQLITE_ENABLE_STAT4 compile-time option.

<li> Add the [PRAGMA legacy_alter_table=ON] command that causes the
     "ALTER TABLE RENAME" command to behave as it did in SQLite versions 3.24.0
     and earlier: references to the renamed table inside the bodies of triggers
     and views are not updated.  This new pragma provides a compatibility
     work around for older programs that expected the older, wonky behavior
     of ALTER TABLE RENAME.

newsitem {2018-11-05} {Release 3.25.3} {
SQLite [version 3.25.3] is a third patch against 3.25.0 that fixes various
problems that have come to light and which seem serious enough to 
justify a patch.
}

newsitem {2018-09-25} {Release 3.25.2} {
SQLite [version 3.25.2] is another patch against 3.25.0 that fixes still
more problems associated with the new [window function] feature and the
[ALTER TABLE] enhancements.  Of particular note is the new
[PRAGMA legacy_alter_table=ON] command, which causes the ALTER TABLE RENAME
command to behave in the same goofy way that it did before the enhancements
