<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].

<li>Begin enforcing [SQLITE_LIMIT_VDBE_OP]. The documentation has always
warned that this limit might be enforced in the future. That day has
now come.
