<h2>SQLite Release 3.7.9 On 2011 November 1 (3.7.9)</h2><p><ul>
121
<li>If a search token (on the right-hand side of the MATCH operator) in
122
<a href="../fts3.html#fts4">FTS4</a> begins with "^" then that token must be the first in its field
123
of the document. <b>** Potentially Incompatible Change **</b>
124
<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>
125
to the <a href="../c3ref/db_status.html">sqlite3_db_status()</a> interface.
126
<li>Removed support for <a href="../compile.html#enable_stat2">SQLITE_ENABLE_STAT2</a>, replacing it with the much
127
more capable <a href="../compile.html#enable_stat3">SQLITE_ENABLE_STAT3</a> option.
128
<li>Enhancements to the sqlite3_analyzer utility program, including the
129
--pageinfo and --stats options and support for multiplexed databases.
130
<li>Enhance the <a href="../c3ref/data_count.html">sqlite3_data_count()</a> interface so that it can be used to
131
determine if SQLITE_DONE has been seen on the prepared statement.
132
<li>Added the <a href="../c3ref/c_fcntl_chunk_size.html#sqlitefcntloverwrite">SQLITE_FCNTL_OVERWRITE</a> file-control by which the SQLite core
133
indicates to the VFS that the current transaction will overwrite the
134
entire database file.
135
<li>Increase the default <a href="../malloc.html#lookaside">lookaside memory allocator</a> allocation size from
137
<li>Enhanced the query planner so that it can factor terms in and out of
138
OR expressions in the WHERE clause in an effort to find better indices.
139
<li>Added the <a href="../compile.html#direct_overflow_read">SQLITE_DIRECT_OVERFLOW_READ</a> compile-time option, causing
140
<a href="../fileformat2.html#ovflpgs">overflow pages</a> to be read directly from the database file,
141
bypassing the <a href="../c3ref/pcache_methods2.html">page cache</a>.
142
<li>Remove limits on the magnitude of precision and width value in the
143
format specifiers of the <a href="../c3ref/mprintf.html">sqlite3_mprintf()</a> family of string rendering
145
<li>Fix a bug that prevent <a href="../lang_altertable.html">ALTER TABLE ... RENAME</a> from working
146
on some virtual tables in a database with a UTF16 encoding.
147
<li>Fix a bug in ASCII-to-float conversion that causes slow performance and
148
incorrect results when converting numbers with ridiculously large exponents.
149
<li>Fix a bug that causes incorrect results in aggregate queries that use
150
multiple aggregate functions whose arguments contain complicated expressions
151
that differ only in the case of string literals contained within those
153
<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
154
working correctly if their names were capitalized.
155
<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
157
<li>Fix a bug in <a href="../vtab.html">virtual table</a> implementation that causes a crash if
158
an <a href="../fts3.html#fts4">FTS4</a> table is <a href="../lang_droptable.html">dropped</a> inside a transaction and
159
a <a href="../lang_savepoint.html">SAVEPOINT</a> occurs afterwards.
