<li>Added the [sqlite3_db_config](db,[SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION]) interface
    which allows the [sqlite3_load_extension()] C-API to be enabled while keeping the
    [load_extension()] SQL function disabled for security.
<li>Change the [temporary directory search algorithm] on Unix to allow directories
    read and execute permission, but without read permission, to serve as temporary
    directories.  Apply this same standard to the "." fallback directory.
<p><b>Bug Fixes:</b>
<li>Fix a problem with the multi-row one-pass DELETE optimization that was
    causing it to compute incorrect answers with a self-referential subquery in
    the WHERE clause.  Fix for ticket
    [https://www.sqlite.org/src/info/dc6ebeda9396087|dc6ebeda9396087]
<li>When checking for the WHERE-clause push-down optimization, verify that all terms
    of the compound inner SELECT are non-aggregate, not just the last term. Fix for ticket
    [https://www.sqlite.org/src/info/f7f8c97e97597|f7f8c97e97597].
<li>Fix a locking race condition in Windows that can occur when two or more processes
    attempt to recover the same [hot journal] at the same time.
