<h2>SQLite Release 3.10.2 On 2016-01-20</h2><p><b>Changes in version 3.10.0 (2016-01-06):</b></p>
<p><ol class='lessindent'>
<p><b>General improvements:</b>
<li value='1'>Added support for <a href="../lang_expr.html#like">LIKE</a>, <a href="../lang_expr.html#glob">GLOB</a>, and <a href="../lang_expr.html#regexp">REGEXP</a> operators on <a href="../vtab.html">virtual tables</a>.
<li>Added the <a href="../vtab.html#colUsed">colUsed field</a> to <a href="../c3ref/index_info.html">sqlite3_index_info</a> for use by
the <a href="../vtab.html#xbestindex">sqlite3_module.xBestIndex</a> method.
<li>Enhance the <a href="../pragma.html#pragma_cache_spill">PRAGMA cache_spill</a> statement to accept a 32-bit integer
parameter which is the threshold below which cache spilling is prohibited.
<li>On unix, if a symlink to a database file is opened, then the corresponding
journal files are based on the actual filename, not the symlink name.
<li>Added the "--transaction" option to <a href="../sqldiff.html">sqldiff</a>.
<li>Added the <a href="../c3ref/db_cacheflush.html">sqlite3_db_cacheflush()</a> interface.
<li>Added the <a href="../c3ref/strlike.html">sqlite3_strlike()</a> interface.
<li>When using <a href="../mmap.html">memory-mapped I/O</a> map the database file read-only so that stray pointers
and/or array overruns in the application cannot accidentally modify the database file.
<li>Added the <em>experimental</em> <a href="../c3ref/snapshot_get.html">sqlite3_snapshot_get()</a>, <a href="../c3ref/snapshot_open.html">sqlite3_snapshot_open()</a>,
and <a href="../c3ref/snapshot_free.html">sqlite3_snapshot_free()</a> interfaces. These are subject to change or removal in
a subsequent release.
<li>Enhance the <a href="../lang_datefunc.html#localtime">'utc' modifier</a> in the <a href="../lang_datefunc.html">date and time functions</a> so that it is a no-op if
the date/time is known to already be in UTC. (This is not a compatibility break since
the behavior has long been documented as "undefined" in that case.)
<li>Added the <a href="../json1.html#jgrouparray">json_group_array()</a> and <a href="../json1.html#jgroupobject">json_group_object()</a> SQL functions in the
<a href="../json1.html#jmini">json</a> extension.
<li>Added the <a href="../compile.html#like_doesnt_match_blobs">SQLITE_LIKE_DOESNT_MATCH_BLOBS</a> compile-time option.
<li>Many small performance optimizations.
<p><b>Portability enhancements:</b>
<li>Work around a sign-extension bug in the optimizer of the HP C compiler on HP/UX.
<a href="https://www.sqlite.org/src/fdiff?sbs=1&v1=869c95b0fc73026d&v2=232c242a0ccb3d67">(details)</a>
<p><b>Enhancements to the <a href="../cli.html">command-line shell</a>:</b>
<li>Added the ".changes ON|OFF" and ".vfsinfo" <a href="../cli.html#dotcmd">dot-commands</a>.
<li>Translate between MBCS and UTF8 when
running in <a href="https://en.wikipedia.org/wiki/Cmd.exe">cmd.exe</a> on Windows.
<p><b>Enhancements to makefiles:</b>
<li>Added the --enable-editline and --enable-static-shell options
to the various autoconf-generated configure scripts.
<li>Omit all use of "awk" in the makefiles, to make building easier for MSVC users.
<p><b>Important fixes:</b>
<li>Fix inconsistent integer to floating-point comparison operations that
could result in a corrupt index if the index is created on a table
column that contains both large integers and floating point values
of similar magnitude. Ticket
<a href="https://www.sqlite.org/src/tktview?name=38a97a87a6">38a97a87a6</a>.
<li>Fix an infinite-loop in the query planner that could occur on
malformed <a href="../lang_with.html">common table expressions</a>.
<li>Various bug fixes in the <a href="../sqldiff.html">sqldiff</a> tool.
</ol>
<p><b>Additional changes in version 3.10.1 (2016-01-14):</b></p>
<p><ol class='lessindent'>
<p><b>New feature:</b>
<li value='22'>Add the <a href="../c3ref/c_fcntl_begin_atomic_write.html#sqlitefcntljournalpointer">SQLITE_FCNTL_JOURNAL_POINTER</a> file control.
<p><b>Bug fix:</b>
<li>Fix a 16-month-old bug in the query planner that could generate incorrect results
when a scalar subquery attempts to use the <a href="../queryplanner.html#partialsort">block sorting</a> optimization. Ticket
<a href="https://www.sqlite.org/src/info/cb3aa0641d9a4">cb3aa0641d9a4</a>.
</ol>
<p><b>Additional changes in version 3.10.2 (2016-01-20):</b></p>
<p><ol class='lessindent'>
<p><b>Critical bug fix:</b>
<li value='24'>Version 3.10.0 introduced a case-folding bug in the <a href="../lang_expr.html#like">LIKE</a> operator which is fixed
by this patch release. Ticket
<a href="https://www.sqlite.org/src/info/80369eddd5c94">80369eddd5c94</a>.
<p><b>Other miscellaneous bug fixes:</b>
<li>Fix a use-after-free that can occur when SQLite is compiled with -DSQLITE_HAS_CODEC.
<li>Fix the build so that it works with -DSQLITE_OMIT_WAL.
<li>Fix the configure script for the amalgamation so that the --readline option works again
on Raspberry PIs.
<p><b>Hashes:</b>
<li>SQLITE_SOURCE_ID: "2016-01-20 15:27:19 17efb4209f97fb4971656086b138599a91a75ff9"
<li>SHA1 for sqlite3.c: f7088b19d97cd7a1c805ee95c696abd54f01de4f
