+<h2>SQLite Release 3.8.11 On 2015-07-27</h2><p><ol class='lessindent'>
+<li>Added the experimental <a href="../rbu.html">RBU</a> extension. 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>.
+ (Measured using
+ <a href="http://valgrind.org/docs/manual/cg-manual.html">cachegrind</a> on the
+ <a href="https://www.sqlite.org/src/artifact/83f6b3318f7ee">speedtest1.c</a> workload on
+ Ubuntu 14.04 x64 with gcc 4.8.2 and -Os. 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/f2ad7de056ab1dc9200">f2ad7de056ab1dc9200</a>
+<li>Fix <a href="../lang_createtable.html#createtabas">CREATE TABLE AS</a> so that it does not leave NULL entries in the
+ <a href="../schematab.html">sqlite_master table</a> if the SELECT statement on the right-hand side
+ aborts with an error. 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.
