<h2>SQLite Release 3.9.1 On 2015-10-16</h2><p><b>Prior changes from version 3.9.0 (2015-10-14):</b></p>
<p><ol class='lessindent'>
<p><b>Policy Changes:</b>
<li value='1'>The <a href="../versionnumbers.html">version numbering conventions</a> for SQLite are revised to use the
emerging standard of <a href="http://semver.org/">semantic versioning</a>.
<p><b>New Features And Enhancements:</b>
<li>Added <a href="../json1.html">the json1 extension</a> module in the source tree, and in the <a href="../amalgamation.html">amalgamation</a>.
Enable support using the <a href="../compile.html#enable_json1">SQLITE_ENABLE_JSON1</a> compile-time option.
<li>Added <a href="../fts5.html">Full Text Search version 5 (FTS5)</a> to the <a href="../amalgamation.html">amalgamation</a>, enabled
using <a href="../compile.html#enable_fts5">SQLITE_ENABLE_FTS5</a>. FTS5 will be considered "experimental" (subject
to incompatible changes) for at least one more release cycle.
<li>The <a href="../lang_createview.html">CREATE VIEW</a> statement now accepts an optional list of
column names following the view name.
<li>Added support for <a href="../expridx.html">indexes on expressions</a>.
<li>Added support for <a href="../vtab.html#tabfunc2">table-valued functions</a> in the FROM clause of a
<a href="../lang_select.html">SELECT</a> statement.
<li>Added support for <a href="../vtab.html#epovtab">eponymous virtual tables</a>.
<li>A <a href="../lang_createview.html">VIEW</a> may now reference undefined tables and functions when
initially created. Missing tables and functions are reported when
the VIEW is used in a query.
<li>Added the <a href="../c3ref/value_subtype.html">sqlite3_value_subtype()</a> and <a href="../c3ref/result_subtype.html">sqlite3_result_subtype()</a>
interfaced (used by <a href="../json1.html">the json1 extension</a>).
<li>The query planner is now able to use <a href="../partialindex.html">partial indexes</a> that contain
AND-connected terms in the WHERE clause.
<li>The sqlite3_analyzer.exe utility is updated to report the depth of
each btree and to show the average fanout for indexes and
WITHOUT ROWID tables.
<li>Enhanced the <a href="../dbstat.html">dbstat virtual table</a> so that it can be used as a
<a href="../vtab.html#tabfunc2">table-valued function</a> where the argument is the schema to be
analyzed.
<p><b>Other changes:</b>
<li>The <a href="../c3ref/aggregate_count.html">sqlite3_memory_alarm()</a> interface, which has been deprecated and
undocumented for 8 years, is changed into a no-op.
<p><b>Important fixes:</b>
<li>Fixed a critical bug in the
<a href="https://www.sqlite.org/see/doc/trunk/www/readme.wiki">SQLite Encryption Extension</a> that
could cause the database to become unreadable and unrecoverable if a <a href="../lang_vacuum.html">VACUUM</a> command
changed the size of the encryption nonce.
<li>Added a memory barrier in the implementation of
<a href="../c3ref/initialize.html">sqlite3_initialize()</a> to help ensure that it is thread-safe.
<li>Fix the <a href="../optoverview.html#or_opt">OR optimization</a> so that it always ignores subplans that
do not use an index.
<li>Do not apply the WHERE-clause pushdown optimization on terms that originate
in the ON or USING clause of a LEFT JOIN. Fix for ticket
<a href="https://www.sqlite.org/src/info/c2a19d81652f40568c">c2a19d81652f40568c</a>.
</ol>
<p><b>Changes in this specific patch release, version 3.9.1 (2015-10-16):</b></p>
<p><ol class='lessindent'>
<li value='18'>Fix <a href="../json1.html">the json1 extension</a> so that it does <u>not</u> recognize ASCII form-feed as a
whitespace character, in order to comply with RFC-7159. Fix for ticket
<a href="https://www.sqlite.org/src/info/57eec374ae1d0a1d">57eec374ae1d0a1d</a>
<li>Add a few #ifdef and build script changes to address compilation issues that
appeared after the 3.9.0 release.
<li>SQLITE_SOURCE_ID: ""2015-10-16 17:31:12 767c1727fec4ce11b83f25b3f1bfcfe68a2c8b02"
<li>SHA1 for sqlite3.c: 5e6d1873a32d82c2cf8581f143649940cac8ae49

in a single page and a <a href="../chronology.html">chronology</a> are both also available.

check-in is available at
