<li>Enhance the [SQLITE_DIRECT_OVERFLOW_READ] option so that it works
    in [WAL mode] as long as the pages being read are not in the WAL file.
<li>Enhance the 
    [https://www.sqlite.org/src/doc/trunk/doc/lemon.html|LEMON parser generator]
    so that it can store the parser object as a stack variable rather than 
    allocating space from the heap and make use of that enhancement in
    the [amalgamation].



<li>Other performance improvements. Uses about [CPU cycles used|6.5% fewer CPU cycles].
<p><b>Bug Fixes:</b>
<li>Throw an error if the ON clause of a LEFT JOIN references tables
    to the right of the ON clause.  This is the same behavior as
    PostgreSQL.  Formerly, SQLite silently converted the LEFT JOIN
    into an INNER JOIN.  Fix for ticket
    [https://www.sqlite.org/src/info/25e335f802dd|25e335f802dd].

    warned that this limit might be enforced in the future.  That day has
    now come.
