<h2>SQLite Release 3.44.0 On 2023-11-01</h2><p><ol class='lessindent'>
<li> <a href="../lang_aggfunc.html">Aggregate functions</a> can now include an ORDER BY clause after their last
     parameter.  The arguments to the function are processed in the order
     specified.  This can be important for functions like
     <a href="../lang_aggfunc.html#group_concat">string_agg()</a> and <a href="../json1.html#jgrouparray">json_group_array()</a>.
<li> Add support for the <a href="../lang_corefunc.html#concat">concat()</a> and <a href="../lang_corefunc.html#concat_ws">concat_ws()</a> scalar SQL functions,
     compatible with PostgreSQL, SQLServer, and MySQL.
<li> Add support for the <a href="../lang_aggfunc.html#group_concat">string_agg()</a> aggregate SQL function, compatible
     with PostgreSQL and SQLServer.
<li> New conversion letters on the <a href="../lang_datefunc.html#strftm">strftime() SQL function</a>: %e %F %I %k %l %p %P %R %T %u
<li> Add new C-language APIs:  <a href="../c3ref/get_clientdata.html">sqlite3_get_clientdata()</a> and <a href="../c3ref/get_clientdata.html">sqlite3_set_clientdata()</a>.
<li> Many errors associated with CREATE TABLE are now raised when the CREATE TABLE statement
     itself is run, rather than being deferred until the first time the table is actually
     used.
<li> The <a href="../pragma.html#pragma_integrity_check">PRAGMA integrity_check</a> command now verifies the consistency of the
     content in various built-in <a href="../vtab.html">virtual tables</a> using the new <a href="../vtab.html#xintegrity">xIntegrity method</a>.
     This works for the <a href="../fts3.html">FTS3</a>, <a href="../fts3.html#fts4">FTS4</a>, <a href="../fts5.html">FTS5</a>, <a href="../rtree.html">RTREE</a>, and <a href="../geopoly.html">GEOPOLY</a> extensions.
<li> The <a href="../c3ref/c_dbconfig_defensive.html#sqlitedbconfigdefensive">SQLITE_DBCONFIG_DEFENSIVE</a> setting now prevents <a href="../pragma.html#pragma_writable_schema">PRAGMA writable_schema</a>
     from being turned on.  Previously writable_schema could be turned on, but would
     not actually allow the schema to be writable.  Now it simply cannot be turned on.
<li> Tag the built-in <a href="../fts3.html">FTS3</a>, <a href="../fts3.html#fts4">FTS4</a>, <a href="../fts5.html">FTS5</a>, <a href="../rtree.html">RTREE</a>, and <a href="../geopoly.html">GEOPOLY</a> virtual tables as
     <a href="../c3ref/c_vtab_constraint_support.html#sqlitevtabinnocuous">SQLITE_VTAB_INNOCUOUS</a> so that they can be used inside of triggers in
     high-security deployments.
<li> The <a href="../pragma.html#pragma_case_sensitive_like">PRAGMA case_sensitive_like</a> statement is deprecated, as its use when the
     schema contains LIKE operators can lead to reports of database corruption
     by <a href="../pragma.html#pragma_integrity_check">PRAGMA integrity_check</a>.
<li> <a href="../compile.html#use_seh">SQLITE_USE_SEH</a> (Structured Exception Handling) is now enabled by default whenever
     SQLite is built using the Microsoft C compiler.  It can be disabled using
     -DSQLITE_USE_SEH=0
<li> Query planner optimizations:
     <ol type="a">
     <li> In partial index scans, if the WHERE clause implies a constant value for a table
          column, replace occurrences of that table column with the constant. This
          increases the likelihood of the partial index being a covering index.
     <li> Disable the view-scan optimization (added in <a href="../releaselog/3_42_0.html">version 3.42.0</a> - item 1c) 
          as it was causing multiple performance regressions. In its place, reduce
          the estimated row count for DISTINCT subqueries by a factor of 8.
     </ol>
<li> SQLite now performs run-time detection of whether or not the underlying hardware
     supports "long double" with precision greater than "double" and uses appropriate
     floating-point routines depending on what it discovered.
<li> The <a href="../cli.html">CLI</a> for Windows now defaults to using UTF-8 for both input
     and output on platforms that support it.  The --no-utf8 option is available
     to disable UTF8 support.
