<h2>SQLite Release 3.7.5 On 2011-02-01</h2><p><ol class='lessindent'>
<li> Added the <a href="../c3ref/mprintf.html">sqlite3_vsnprintf()</a> interface.
<li> Added the <a href="../c3ref/c_dbstatus_options.html#sqlitedbstatuslookasidehit">SQLITE_DBSTATUS_LOOKASIDE_HIT</a>,
<a href="../c3ref/c_dbstatus_options.html#sqlitedbstatuslookasidemisssize">SQLITE_DBSTATUS_LOOKASIDE_MISS_SIZE</a>, and
<a href="../c3ref/c_dbstatus_options.html#sqlitedbstatuslookasidemissfull">SQLITE_DBSTATUS_LOOKASIDE_MISS_FULL</a> options for the
<a href="../c3ref/db_status.html">sqlite3_db_status()</a> interface.
<li> Added the <a href="../compile.html#omit_autoreset">SQLITE_OMIT_AUTORESET</a> compile-time option.
<li> Added the <a href="../compile.html#default_foreign_keys">SQLITE_DEFAULT_FOREIGN_KEYS</a> compile-time option.
<li> Updates to <a href="../c3ref/stmt_readonly.html">sqlite3_stmt_readonly()</a> so that its result is well-defined
for all prepared statements and so that it works with <a href="../lang_vacuum.html">VACUUM</a>.
<li> Added the "-heap" option to the <a href="../cli.html">command-line shell</a>
<li> Fix <a href="https://www.sqlite.org/src/info/5d863f876e">a bug</a> involving
frequent changes in and out of WAL mode and
VACUUM that could (in theory) cause database corruption.
<li> Enhance the <a href="../c3ref/profile.html">sqlite3_trace()</a> mechanism so that nested SQL statements
such as might be generated by virtual tables are shown but are shown
in comments and without parameter expansion. This
greatly improves tracing output when using the FTS3/4 and/or RTREE
virtual tables.
<li> Change the xFileControl() methods on all built-in VFSes to return
<a href="../rescode.html#notfound">SQLITE_NOTFOUND</a> instead of <a href="../rescode.html#error">SQLITE_ERROR</a> for an unrecognized
operation code.
<li> The SQLite core invokes the <a href="../c3ref/c_fcntl_begin_atomic_write.html#sqlitefcntlsyncomitted">SQLITE_FCNTL_SYNC_OMITTED</a>
<a href="../c3ref/file_control.html">file control</a>
to the VFS in place of a call to xSync if the database has
<a href="../pragma.html#pragma_synchronous">PRAGMA synchronous</a> set to OFF.
</ol></p>
<p>A <a href="../changes.html">complete list of SQLite releases</a>
in a single page and a <a href="../chronology.html">chronology</a> are both also available.
A detailed history of every
check-in is available at
<a href="https://www.sqlite.org/src/timeline">
SQLite version control site</a>.</p>
