<li>Added the [FTS5 detail option].
<li>Added the "EXTRA" option to [PRAGMA synchronous] that does a sync of the
    containing directory when a rollback journal is unlinked in DELETE mode,
    for better durability.  The [SQLITE_EXTRA_DURABLE] compile-time option enables
    [PRAGMA synchronous=EXTRA] by default.
<li>Enhanced the [query planner] so that it is able to use
    a [covering index] as part of the [OR optimization].


<li>Many micro-optimizations, resulting in a library that is both smaller
    and faster than the previous release.
<p><b>Enhancements to the [command-line shell]:</b>
<li>By default, the shell is now in "auto-explain" mode.  The output of
    [EXPLAIN] commands is automatically formatted.
<li>Added the ".vfslist" [dot-commands|dot-command].
<li>The [SQLITE_ENABLE_EXPLAIN_COMMENTS] compile-time option is now turned
    on by default in the standard builds.
<p><b>Enhancements to the [TCL Interface]:</b>
