+<h2>SQLite Release 3.42.0 On 2023-05-16</h2><p><ol class='lessindent'>
+<li> Add the <a href="../fts5.html#the_secure_delete_configuration_option">FTS5 secure-delete command</a>. This option causes all forensic traces
+ to be removed from the FTS5 inverted index when content is deleted.
+<li> Enhance the <a href="../json1.html">JSON SQL functions</a> to support <a href="../json1.html#json5">JSON5 extensions</a>.
+<li> The <a href="../c3ref/c_config_covering_index_scan.html#sqliteconfiglog">SQLITE_CONFIG_LOG</a> and <a href="../c3ref/c_config_covering_index_scan.html#sqliteconfigpcachehdrsz">SQLITE_CONFIG_PCACHE_HDRSZ</a> calls to <a href="../c3ref/config.html">sqlite3_config()</a>
+ are now allowed to occur <i>after</i> <a href="../c3ref/initialize.html">sqlite3_initialize()</a>.
+<li> New <a href="../c3ref/db_config.html">sqlite3_db_config()</a> options: <a href="../c3ref/c_dbconfig_defensive.html#sqlitedbconfigstmtscanstatus">SQLITE_DBCONFIG_STMT_SCANSTATUS</a> and
+ <a href="../c3ref/c_dbconfig_defensive.html#sqlitedbconfigreversescanorder">SQLITE_DBCONFIG_REVERSE_SCANORDER</a>.
+<li> Query planner improvements:
+ <ol type="a">
+ <li> Enable the "count-of-view" optimization by default.
+ <li> Avoid computing unused columns in subqueries.
+ <li> Improvements to the <a href="../optoverview.html#pushdown">push-down optimization</a>.
+ </ol>
+<li> Enhancements to the <a href="../cli.html">CLI</a>:
+ <ol type="a">
+ <li> Add the --unsafe-testing command-line option. Without this option, some
+ dot-commands (ex: ".testctrl") are now disabled because those commands
+ that are intended for testing only and can cause malfunctions if misused.
+ <li> Allow commands ".log on" and ".log off", even in --safe mode.
+ <li> "--" as a command-line argument means all subsequent arguments that
+ start with "-" are interpreted as normal non-option argument.
+ <li> Magic parameters ":inf" and ":nan" bind to floating point literals
+ Infinity and NaN, respectively.
+ <li> The --utf8 command-line option omits all translation to or from
+ MBCS on the Windows console for interactive sessions, and sets
+ the console code page for UTF-8 I/O during such sessions.
+ The --utf8 option is a no-op on all other platforms.
+ </ol>
+<li> Add the ability for <a href="../appfunc.html">application-defined SQL functions</a> to have the same name
+ as join keywords: CROSS, FULL, INNER, LEFT, NATURAL, OUTER, or RIGHT.
+<li> Enhancements to <a href="../pragma.html#pragma_integrity_check">PRAGMA integrity_check</a>:
+ <ol type="a">
+ <li> Detect and raise an error when a NaN value is stored in a NOT NULL column.
+ <li> Improved error message output identifies the root page of a b-tree when
+ an error is found within a b-tree.
+ </ol>
+<li> Allow the <a href="../sessionintro.html">session extension</a> to be configured to capture changes from
+ tables that lack an explicit ROWID.
+<li> Added the <a href="../lang_datefunc.html#subsec">subsecond modifier</a> to the <a href="../lang_datefunc.html">date and time functions</a>.
+<li> Negative values passed into <a href="../c3ref/sleep.html">sqlite3_sleep()</a> are henceforth interpreted as 0.
+<li> The maximum recursion depth for JSON arrays and objects is lowered from 2000
+ to 1000.
+<li> Extended the <a href="../printf.html">built-in printf()</a> function so the <a href="../printf.html#comma">comma option</a> now works with
+ floating-point conversions in addition to integer conversions.
+<li> Miscellaneous bug fixes and performance optimizations
