<h2>SQLite Release 3.7.1 On 2010-08-23</h2><p><ol class='lessindent'>
<li> Added new commands <a href="../c3ref/c_dbstatus_options.html#sqlitedbstatusschemaused">SQLITE_DBSTATUS_SCHEMA_USED</a> and
<a href="../c3ref/c_dbstatus_options.html#sqlitedbstatusstmtused">SQLITE_DBSTATUS_STMT_USED</a> to the <a href="../c3ref/db_status.html">sqlite3_db_status()</a> interface, in
order to report out the amount of memory used to hold the schema and
prepared statements of a connection.
<li> Increase the maximum size of a database pages from 32KiB to 64KiB.
<li> Use the <a href="../optoverview.html#like_opt">LIKE optimization</a> even if the right-hand side string contains
no wildcards.
<li> Added the <a href="../c3ref/c_fcntl_begin_atomic_write.html#sqlitefcntlchunksize">SQLITE_FCNTL_CHUNK_SIZE</a> verb to the <a href="../c3ref/file_control.html">sqlite3_file_control()</a>
interface for both unix and windows, to cause database files to grow in
large chunks in order to reduce disk fragmentation.
<li> Fixed a bug in the query planner that caused performance regressions
relative to 3.6.23.1 on some complex joins.
<li> Fixed a typo in the OS/2 backend.
<li> Refactored the pager module.
<li> The SQLITE_MAX_PAGE_SIZE compile-time option is now silently ignored.
The maximum page size is hard-coded at 65536 bytes.
</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>
