<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.
<p><b>Hashes:</b>
<li>SQLITE_SOURCE_ID: 2021-12-30 15:30:28 378629bf2ea546f73eee84063c5358439a12f7300e433f18c9e1bddd948dea62
<li>SHA3-256 for sqlite3.c: 915afb3f29c2d217ea0c283326a9df7d505e6c73b40236f0b33ded91f812d174
</ol></p>

in a single page and a <a href="../chronology.html">chronology</a> are both also available.

check-in is available at
