+<h2>SQLite Release 3.39.2 On 2022-07-21</h2><p><b>Prior changes from version 3.39.0 (2022-06-25):</b></p>
+<p><ol class='lessindent'>
+<li value='1'> Add (long overdue) support for <a href="../lang_select.html#rjoin">RIGHT and FULL OUTER JOIN</a>.
+<li> Add new binary comparison operators <a href="../lang_expr.html#isdf">IS NOT DISTINCT FROM</a> and <a href="../lang_expr.html#isdf">IS DISTINCT FROM</a>
+ that are equivalent to IS and IS NOT, respective, for compatibility with
+ PostgreSQL and SQL standards.
+<li> Add a new return code (value "3") from the <a href="../c3ref/vtab_distinct.html">sqlite3_vtab_distinct()</a>
+ interface that indicates a query that has both DISTINCT and ORDER BY
+ clauses.
+<li> Added the <a href="../c3ref/db_name.html">sqlite3_db_name()</a> interface.
+<li> The unix os interface resolves all symbolic links in database
+ filenames to create a canonical name for the database before the
+ file is opened.
+ If the <a href="../c3ref/c_open_autoproxy.html">SQLITE_OPEN_NOFOLLOW</a> flag is used with <a href="../c3ref/open.html">sqlite3_open_v2()</a>
+ or similar, the open will fail if any element of the path is a
+ symbolic link.
+<li> Defer materializing views until the materialization
+ is actually needed, thus avoiding unnecessary work if the materialization turns
+ out to never be used.
+<li> The <a href="../lang_select.html#resultset">HAVING clause</a> of a <a href="../lang_select.html">SELECT statement</a> is now allowed on any aggregate query,
+ even queries that do not have a <a href="../lang_select.html#resultset">GROUP BY clause</a>.
+<li> Many <a href="../cpu.html#microopt">microoptimizations</a> collectively reduce CPU cycles by about 2.3%.
+</ol>
+<p><b>Prior changes from version 3.39.1 (2022-07-13):</b></p>
+<p><ol class='lessindent'>
+<li value='9'> Fix an incorrect result from a query that uses a view that contains a compound
+ SELECT in which only one arm contains a RIGHT JOIN and where the view is not
+ the first FROM clause term of the query that contains the view.
+ <a href="https://sqlite.org/forum/forumpost/174afeae5734d42d">forum post 174afeae5734d42d</a>.
+<li> Fix some harmless compiler warnings.
+<li> Fix a long-standing problem with <a href="../lang_altertable.html#altertabrename">ALTER TABLE RENAME</a> that can only arise
+ if the <a href="../c3ref/limit.html">sqlite3_limit</a>(<a href="../c3ref/c_limit_attached.html#sqlitelimitsqllength">SQLITE_LIMIT_SQL_LENGTH</a>) is set to a very small value.
+<li> Fix a long-standing problem in <a href="../fts3.html">FTS3</a> that can only arise when compiled with
+ the <a href="../compile.html#enable_fts3_parenthesis">SQLITE_ENABLE_FTS3_PARENTHESIS</a> compile-time option.
+<li> Fix the build so that is works when the <a href="../compile.html#debug">SQLITE_DEBUG</a> and
+ <a href="../compile.html#omit_windowfunc">SQLITE_OMIT_WINDOWFUNC</a> compile-time options are both provided at the
+ same time.
+<li> Fix the initial-prefix optimization for the <a href="../lang_expr.html#regexp">REGEXP</a> extension so that it works
+ correctly even if the prefix contains characters that require a 3-byte UTF8
+ encoding.
+<li> Enhance the <a href="../stmt.html">sqlite_stmt</a> virtual table so that it buffers all of its output.
+</ol>
+<p><b>Changes in this specific patch release, version 3.39.2 (2022-07-21):</b></p>
+<p><ol class='lessindent'>
+<li value='16'> Fix a performance regression in the query planner associated with rearranging
+ the order of FROM clause terms in the presences of a LEFT JOIN.
+<li> Apply fixes for CVE-2022-35737, Chromium bugs 1343348 and 1345947,
+ <a href="https://sqlite.org/forum/forumpost/3607259d3c">forum post 3607259d3c</a>, and
