<li>The query planner now does a better job of optimizing [virtual table]
    accesses in a 3-way or higher join where constraints on the virtual
    table are split across two or more other tables of the join.
<li>More efficient handling of [application-defined SQL functions], especially
    in cases where the application defines hundreds or thousands of 
    custom functions.
<li>The query planner considers the LIMIT clause when estimating the cost
    or ORDER BY.
<li>The configure script (on unix) automatically detects the availablity of
    pread() and pwrite() and sets of compile-time options to use those OS
    interfaces if they are available.
<li>Reduce the amount of memory needed to hold the schema.
<li>Other miscellanous micro-optimizations for improved performance and reduced
    memory usage.
<p><b>New Features:</b>
<li>Added the [SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER] option to [sqlite3_db_config()]
    which allows the two-argument version of the [fts3_tokenizer()] SQL function to
    be enabled or disabled at run-time.
<li>Added the [https://www.sqlite.org/src/artifact/d7cc99350?ln=403-443|sqlite3rbu_bp_progress()]
    interface to the [RBU] extension.
<li>The [PRAGMA defer_foreign_keys=ON] statement now also disables 
    [foreign key actions|RESTRICT actions] on foreign key.

<li>Added the [SQLITE_DEFAULT_SYNCHRONOUS] and [SQLITE_DEFAULT_WAL_SYNCHRONOUS]
    compile-time options.  The [SQLITE_DEFAULT_SYNCHRONOUS] compile-time option
    replaces the [SQLITE_EXTRA_DURABLE] option, which is no longer supported.
<li>Enhanced the ".stats" command in the [command-line shell] to show more
    information about I/O performance obtained from /proc, when available.
<p><b>Bug fixes:</b>
<li>Make sure the [sqlite3_set_auxdata()] values from multiple triggers
