<li> Added the sorter-reference optimization as a compile-time option.
Only available if compiled with SQLITE_ENABLE_SORTER_REFERENCES.
<li> The [CLI] automatically intercepts the raw [EXPLAIN QUERY PLAN]
output an reformats it into an ASCII-art graph.
<li> Enhance the query planner to allow the [OR optimization] to proceed
even if the OR expression has also been converted into an IN
expression.
<li> Performance improvements in the LEMON-generated parser.
<p><b>Bug fixes:</b>
<li> For the right-hand table of a LEFT JOIN, compute the values
of expressions directly rather than loading precomputed values
out of an [expression index] as the expression index might
not contain the correct value. Ticket
[https://sqlite.org/src/info/7fa8049685b50b5aeb0c2|7fa8049685b50b5aeb0c2]
<li> Do not attempt to use terms from the WHERE clause to enable
indexed lookup of the right-hand table of a LEFT JOIN. Ticket
[https://sqlite.org/src/info/4ba5abf65c5b0f9a96a7a|4ba5abf65c5b0f9a96a7a]
<li> Fix a memory leak that can occur following a failure to open error
in the [CSV virtual table]
<p><b>Hashes:</b>
<li>SQLITE_SOURCE_ID: <i>pending</i>
<li>SHA3-256 for sqlite3.c: <i>pending</i>
