<h2>SQLite Release 3.6.0 On 2008-07-16</h2><p><ol class='lessindent'>
<li>Modifications to the <a href="../c3ref/vfs.html">virtual file system</a> interface
to support a wider range of embedded systems.
See <a href="../35to36.html">35to36.html</a> for additional information.
<font color="red">*** Potentially incompatible change ***</font></li>
<li>All C-preprocessor macros used to control compile-time options
now begin with the prefix "SQLITE_". This may require changes to
applications that compile SQLite using their own makefiles and with
custom compile-time options, hence we mark this as a
<font color="red">*** Potentially incompatible change ***</font></li>
<li>The SQLITE_MUTEX_APPDEF compile-time option is no longer supported.
Alternative mutex implementations can now be added at run-time using
the <a href="../c3ref/config.html">sqlite3_config()</a> interface with the <a href="../c3ref/c_config_covering_index_scan.html#sqliteconfigmutex">SQLITE_CONFIG_MUTEX</a> verb.
<font color="red">*** Potentially incompatible change ***</font></li>
<li>The handling of IN and NOT IN operators that contain a NULL on their
right-hand side expression is brought into compliance with the SQL
standard and with other SQL database engines. This is a bug fix,
but as it has the potential to break legacy applications that depend
on the older buggy behavior, we mark that as a
<font color="red">*** Potentially incompatible change ***</font></li>
<li>The result column names generated for compound subqueries have been
simplified to show only the name of the column of the original table and
omit the table name. This makes SQLite operate more like other SQL
database engines.</li>
<li>Added the <a href="../c3ref/config.html">sqlite3_config()</a> interface for doing run-time configuration
of the entire SQLite library.</li>
<li>Added the <a href="../c3ref/status.html">sqlite3_status()</a> interface used for querying run-time status
information about the overall SQLite library and its subsystems.</li>
<li>Added the <a href="../c3ref/initialize.html">sqlite3_initialize()</a> and <a href="../c3ref/initialize.html">sqlite3_shutdown()</a> interfaces.</li>
<li>The <a href="../c3ref/c_open_autoproxy.html">SQLITE_OPEN_NOMUTEX</a> option was added to <a href="../c3ref/open.html">sqlite3_open_v2()</a>.</li>
<li>Added the <a href="../pragma.html#pragma_page_count">PRAGMA page_count</a> command.</li>
<li>Added the <a href="../c3ref/next_stmt.html">sqlite3_next_stmt()</a> interface.</li>
<li>Added a new <a href="../rtree.html">R*Tree virtual table</a></li>
</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="http://www.sqlite.org/src/timeline">
SQLite version control site</a>.</p>
