Note that this extension is experimental and subject to change in incompatible ways. <li>Added the experimental <a href="../fts5.html">FTS5</a> extension. Note that this extension is experimental and subject to change in incompatible ways. <li>Added the <a href="../c3ref/value_dup.html">sqlite3_value_dup()</a> and <a href="../c3ref/value_dup.html">sqlite3_value_free()</a> interfaces. <li>Enhance the <a href="../spellfix1.html">spellfix1</a> extension to support <a href="../lang_conflict.html">ON CONFLICT</a> clauses. <li>The <a href="../lang_expr.html#isisnot">IS operator</a> is now able to drive indexes. <li>Enhance the query planner to permit <a href="../optoverview.html#autoindex">automatic indexing</a> on FROM-clause subqueries that are implemented by co-routine. <li>Disallow the use of "rowid" in <a href="../lang_with.html">common table expressions</a>. <li>Added the <a href="../pragma.html#pragma_cell_size_check">PRAGMA cell_size_check</a> command for better and earlier detection of database file corruption. <li>Added the <a href="../fts3.html#matchinfo-b">matchinfo 'b' flag</a> to the <a href="../fts3.html#matchinfo">matchinfo()</a> function in <a href="../fts3.html">FTS3</a>. <li>Improved fuzz-testing of database files, with fixes for problems found. <li>Add the fuzzcheck test program and automatically run this program using both SQL and database test cases on "make test". <li>Added the <a href="../c3ref/c_mutex_fast.html">SQLITE_MUTEX_STATIC_VFS1</a> static mutex and use it in the Windows <a href="../vfs.html">VFS</a>. <li>The <a href="../c3ref/profile.html">sqlite3_profile()</a> callback is invoked (by <a href="../c3ref/reset.html">sqlite3_reset()</a> or <a href="../c3ref/finalize.html">sqlite3_finalize()</a>) for statements that did not run to completion. <li>Enhance the page cache so that it can preallocate a block of memory to use for the initial set page cache lines. Set the default preallocation to 100 pages. Yields about a 5% performance increase on common workloads. <li>Miscellaneous micro-optimizations result in 22.3% more work for the same number of CPU cycles relative to the previous release. SQLite now runs twice as fast as <a href="../releaselog/3_8_0.html">version 3.8.0</a> and three times as fast as <a href="../releaselog/3_3_9.html">version 3.3.9</a>.

Your performance may vary.) <li>Added the <a href="../c3ref/result_blob.html">sqlite3_result_zeroblob64()</a> and <a href="../c3ref/bind_blob.html">sqlite3_bind_zeroblob64()</a> interfaces. <p><b>Important bug fixes:</b> <li>Fix <a href="../lang_createtable.html#createtabas">CREATE TABLE AS</a> so that columns of type TEXT never end up holding an INT value.

Ticket <a href="https://www.sqlite.org/src/info/873cae2b6e25b">873cae2b6e25b</a> <li>Fix the <a href="../optoverview.html#skipscan">skip-scan optimization</a> so that it works correctly when the <a href="../optoverview.html#or_opt">OR optimization</a> is used on <a href="../withoutrowid.html">WITHOUT ROWID</a> tables. Ticket <a href="https://www.sqlite.org/src/info/8fd39115d8f46">8fd39115d8f46</a> <li>Fix the <a href="../c3ref/memory_highwater.html">sqlite3_memory_used()</a> and <a href="../c3ref/memory_highwater.html">sqlite3_memory_highwater()</a> interfaces so that they actually do provide a 64-bit answer. <p><b>Hashes:</b> <li>SQLITE_SOURCE_ID: "2015-07-27 13:49:41 b8e92227a469de677a66da62e4361f099c0b79d0" <li>SHA1 for sqlite3.c: 719f6891abcd9c459b5460b191d731cd12a3643e </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.
