    full scan of the main table, in cases where that makes sense.
<li>Allow [table-valued functions] to appear on the right-hand side of an [IN operator].
<li>Created the [dbhash.exe] command-line utility.
<li>Added two new C-language interfaces: [sqlite3_expanded_sql()] and
    [sqlite3_trace_v2()].  These new interfaces subsume the functions of
    [sqlite3_trace()] and [sqlite3_profile()] which are now deprecated.
<li>Added the [json_quote()] SQL function to [the json1 extension].

<p><b>Bug Fixes:</b>
<li>Fix the [ALTER TABLE] command so that it does not corrupt [descending indexes]
    when adding a column to a [legacy_file_format|legacy file format] database.  Ticket
    [https://www.sqlite.org/src/info/f68bf68513a1c15f|f68bf68513a1c15f]
<li>Fix a NULL-pointer dereference/crash that could occurs when a transitive WHERE
    clause references a non-existent collating sequence.  Ticket
    [https://www.sqlite.org/src/info/e8d439c77685eca6|e8d439c77685eca6].

<li>Postpone I/O associated with TEMP files for as long as possible, with the hope
    that the I/O can ultimately be avoided completely.
<li>Merged the [session] extension into trunk.
<li>Added the ".auth ON|OFF" command to the [command-line shell].

<li>Improved the cost estimation for an index scan which includes a WHERE clause
    that can be partially or fully evaluated using columns in the index and without
    having to do a table lookup.  This fixes a performance regression that occurred
    for some obscure queries following the ORDER BY LIMIT optimization introduced
    in [version 3.12.0].
