+<h2>SQLite Release 3.37.1 On 2021-12-30</h2><p><b>Prior changes from version 3.37.0 (2021-11-27):</b></p>
+<p><ol class='lessindent'>
+<li value='1'> <a href="../stricttables.html">STRICT tables</a> provide a prescriptive style of data type management,
+ for developers who prefer that kind of thing.
+<li> When adding columns that contain a
+ <a href="../lang_createtable.html#ckconst">CHECK constraint</a> or a <a href="../gencol.html">generated column</a> containing a <a href="../lang_createtable.html#notnullconst">NOT NULL constraint</a>,
+ the <a href="../lang_altertable.html#altertabaddcol">ALTER TABLE ADD COLUMN</a> now checks new constraints against
+ preexisting rows in the database and will only proceed if no constraints
+ are violated.
+<li> Added the <a href="../pragma.html#pragma_table_list">PRAGMA table_list</a> statement.
+<li> <a href="../cli.html">CLI</a> enhancements:
+ <ol type="a">
+ <li> Add the <a href="../cli.html#dotconn">.connection</a> command, allowing the CLI to keep multiple database
+ connections open at the same time.
+ <li> Add the <a href="../cli.html#safemode">--safe command-line option</a> that disables
+ <a href="../cli.html#dotcmd">dot-commands</a> and SQL statements that might cause side-effects that extend
+ beyond the single database file named on the command-line.
+ <li> Performance improvements when reading SQL statements
+ that span many lines.
+ </ol>
+<li> Added the <a href="../c3ref/autovacuum_pages.html">sqlite3_autovacuum_pages()</a> interface.
+<li> The <a href="../c3ref/deserialize.html">sqlite3_deserialize()</a> does not and has never worked for the TEMP
+ database. That limitation is now noted in the documentation.
+<li> The query planner now omits ORDER BY clauses on subqueries and views
+ if removing those clauses does not change the semantics of the query.
+<li> The <a href="../series.html">generate_series</a> table-valued function extension is modified so that
+ the first parameter ("START") is now required. This is done as a way to
+ demonstrate how to write table-valued functions with required parameters.
+ The legacy behavior is available using the -DZERO_ARGUMENT_GENERATE_SERIES
+ compile-time option.
+<li> Added new <a href="../c3ref/changes.html">sqlite3_changes64()</a> and <a href="../c3ref/total_changes.html">sqlite3_total_changes64()</a> interfaces.
+<li> Added the <a href="../c3ref/c_open_autoproxy.html">SQLITE_OPEN_EXRESCODE</a> flag option to <a href="../c3ref/open.html">sqlite3_open_v2()</a>.
+<li> Use less memory to hold the database schema.
+
+</ol>
+<p><b>Changes in this specific patch release, version 3.37.1 (2021-12-30):</b></p>
+<p><ol class='lessindent'>
+<li value='12'> Fix a bug introduced by the <a href="../lang_upsert.html">UPSERT</a> enhancements of <a href="../releaselog/3_35_0.html">version 3.35.0</a> that
+ can cause incorrect byte-code to be generated for some obscure but valid
+ SQL, possibly resulting in a NULL-pointer dereference.
+<li> Fix an OOB read that can occur in <a href="../fts5.html">FTS5</a> when reading corrupt database files.
+<li> Improved robustness of the --safe option in the <a href="../cli.html">CLI</a>.
+<li> Other minor fixes to assert() statements and test cases.
