<p><ol class='lessindent'>
<li value='1'> Add support for the <a href="../lang_aggfunc.html#aggfilter">FILTER clause on aggregate functions</a>.

<li> The <a href="../pragma.html#pragma_index_info">index_info</a> and <a href="../pragma.html#pragma_index_xinfo">index_xinfo</a> pragmas are enhanced to provide
information about the on-disk representation of <a href="../withoutrowid.html">WITHOUT ROWID</a>
tables.
<li> Add the <a href="../c3ref/drop_modules.html">sqlite3_drop_modules()</a> interface, allowing applications
to disable automatically loaded virtual tables that they do not
need.
<li> Improvements to the <a href="../cli.html#recover">.recover dot-command</a> in the <a href="../cli.html">CLI</a> so that
it recovers more content from corrupt database files.
<li> Enhance the <a href="../rbu.html">RBU</a> extension to support <a href="../expridx.html">indexes on expressions</a>.
<li> Change the schema parser so that it will error out if any of
the type, name, and tbl_name columns of the <a href="../schematab.html">sqlite_master table</a>
have been corrupted and the database connection is not in
<a href="../pragma.html#pragma_writable_schema">writable_schema</a> mode.
<li> The <a href="../pragma.html#pragma_function_list">PRAGMA function_list</a>, <a href="../pragma.html#pragma_module_list">PRAGMA module_list</a>, and
<a href="../pragma.html#pragma_pragma_list">PRAGMA pragma_list</a> commands are now
enabled in all builds by default. Disable them using
<a href="../compile.html#omit_introspection_pragmas">-DSQLITE_OMIT_INTROSPECTION_PRAGMAS</a>.
<li> Add the <a href="../c3ref/c_dbconfig_defensive.html#sqlitedbconfigenableview">SQLITE_DBCONFIG_ENABLE_VIEW</a> option for <a href="../c3ref/db_config.html">sqlite3_db_config()</a>.
<li> Added the <a href="../tclsqlite.html">TCL Interface</a> <a href="../tclsqlite.html#config">config method</a> in order to be able to
disable <a href="../c3ref/c_dbconfig_defensive.html#sqlitedbconfigenableview">SQLITE_DBCONFIG_ENABLE_VIEW</a> as well as control other
<a href="../c3ref/db_config.html">sqlite3_db_config()</a> options from TCL.
<li> Added the <a href="../c3ref/c_deterministic.html#sqlitedirectonly">SQLITE_DIRECTONLY</a> flag for
<a href="../appfunc.html">application-defined SQL functions</a> to prevent those functions from
being used inside triggers and views.
<li> The legacy <a href="../compile.html#enable_stat3">SQLITE_ENABLE_STAT3</a> compile-time option is now a no-op.
</ol>
<p><b>Changes in this specific patch release, version 3.30.1 (2019-10-10):</b></p>
<p><ol class='lessindent'>
<li value='13'> Fix a bug in the <a href="../optoverview.html#flattening">query flattener</a> that might cause a segfault
