+<h2>SQLite Release 3.7.9 On 2011-11-01</h2><p><ol class='lessindent'>
+<li>If a search token (on the right-hand side of the MATCH operator) in
+ <a href="../fts3.html#fts4">FTS4</a> begins with "&#94;" then that token must be the first in its field
+ of the document. <b>** Potentially Incompatible Change **</b>
+<li>Added options <a href="../c3ref/c_dbstatus_options.html#sqlitedbstatuscachehit">SQLITE_DBSTATUS_CACHE_HIT</a> and <a href="../c3ref/c_dbstatus_options.html#sqlitedbstatuscachemiss">SQLITE_DBSTATUS_CACHE_MISS</a>
+ to the <a href="../c3ref/db_status.html">sqlite3_db_status()</a> interface.
+<li>Removed support for <a href="../compile.html#enable_stat2">SQLITE_ENABLE_STAT2</a>, replacing it with the much
+ more capable <a href="../compile.html#enable_stat3">SQLITE_ENABLE_STAT3</a> option.
+<li>Enhancements to the sqlite3_analyzer utility program, including the
+ --pageinfo and --stats options and support for multiplexed databases.
+<li>Enhance the <a href="../c3ref/data_count.html">sqlite3_data_count()</a> interface so that it can be used to
+ determine if SQLITE_DONE has been seen on the prepared statement.
+<li>Added the <a href="../c3ref/c_fcntl_begin_atomic_write.html#sqlitefcntloverwrite">SQLITE_FCNTL_OVERWRITE</a> file-control by which the SQLite core
+ indicates to the VFS that the current transaction will overwrite the
+ entire database file.
+<li>Increase the default <a href="../malloc.html#lookaside">lookaside memory allocator</a> allocation size from
+ 100 to 128 bytes.
+<li>Enhanced the query planner so that it can factor terms in and out of
+ OR expressions in the WHERE clause in an effort to find better indices.
+<li>Added the <a href="../compile.html#direct_overflow_read">SQLITE_DIRECT_OVERFLOW_READ</a> compile-time option, causing
+ <a href="../fileformat2.html#ovflpgs">overflow pages</a> to be read directly from the database file,
+ bypassing the <a href="../c3ref/pcache_methods2.html">page cache</a>.
+<li>Remove limits on the magnitude of precision and width value in the
+ format specifiers of the <a href="../c3ref/mprintf.html">sqlite3_mprintf()</a> family of string rendering
+ routines.
+<li>Fix a bug that prevent <a href="../lang_altertable.html">ALTER TABLE ... RENAME</a> from working
+ on some virtual tables in a database with a UTF16 encoding.
+<li>Fix a bug in ASCII-to-float conversion that causes slow performance and
+ incorrect results when converting numbers with ridiculously large exponents.
+<li>Fix a bug that causes incorrect results in aggregate queries that use
+ multiple aggregate functions whose arguments contain complicated expressions
+ that differ only in the case of string literals contained within those
+ expressions.
+<li>Fix a bug that prevented the <a href="../pragma.html#pragma_page_count">page_count</a> and <a href="../pragma.html#pragma_quick_check">quick_check</a> pragmas from
+ working correctly if their names were capitalized.
+<li>Fix a bug that caused <a href="../lang_vacuum.html">VACUUM</a> to fail if the <a href="../pragma.html#pragma_count_changes">count_changes pragma</a> was
+ engaged.
+<li>Fix a bug in <a href="../vtab.html">virtual table</a> implementation that causes a crash if
+ an <a href="../fts3.html#fts4">FTS4</a> table is <a href="../lang_droptable.html">dropped</a> inside a transaction and
+ a <a href="../lang_savepoint.html">SAVEPOINT</a> occurs afterwards.
+<li>SQLITE_SOURCE_ID:
+ "2011-11-01 00:52:41 c7c6050ef060877ebe77b41d959e9df13f8c9b5e"
