+<h2>SQLite Release 3.11.0 On 2016-02-15</h2><p><ol class='lessindent'>
+<p><b>General improvements:</b>
+<li>Enhanced <a href="../wal.html">WAL mode</a> so that it works efficiently with transactions that are
+ larger than the <a href="../pragma.html#pragma_cache_size">cache_size</a>.
+<li>Added the <a href="../fts5.html#the_detail_option">FTS5 detail option</a>.
+<li>Added the "EXTRA" option to <a href="../pragma.html#pragma_synchronous">PRAGMA synchronous</a> that does a sync of the
+ containing directory when a rollback journal is unlinked in DELETE mode,
+ for better durability. The <a href="../compile.html#extra_durable">SQLITE_EXTRA_DURABLE</a> compile-time option enables
+ <a href="../pragma.html#pragma_synchronous">PRAGMA synchronous=EXTRA</a> by default.
+<li>Enhanced the <a href="../optoverview.html">query planner</a> so that it is able to use
+ a <a href="../queryplanner.html#covidx">covering index</a> as part of the <a href="../optoverview.html#or_opt">OR optimization</a>.
+<li>Avoid recomputing <a href="../lang_createtable.html#notnullconst">NOT NULL</a> and <a href="../lang_createtable.html#ckconst">CHECK constraints</a> on unchanged
+ columns in <a href="../lang_update.html">UPDATE</a> statement.
+<li>Many micro-optimizations, resulting in a library that is
+ faster than the previous release.
+<p><b>Enhancements to the <a href="../cli.html">command-line shell</a>:</b>
+<li>By default, the shell is now in "auto-explain" mode. The output of
+ <a href="../lang_explain.html">EXPLAIN</a> commands is automatically formatted.
+<li>Added the ".vfslist" <a href="../cli.html#dotcmd">dot-command</a>.
+<li>The <a href="../compile.html#enable_explain_comments">SQLITE_ENABLE_EXPLAIN_COMMENTS</a> compile-time option is now turned
+ on by default in the standard builds.
+<p><b>Enhancements to the <a href="../tclsqlite.html">TCL Interface</a>:</b>
+<li>If a database connection is opened with the "-uri 1" option, then
+ <a href="../uri.html">URI filenames</a> are honored by the "backup" and "restore" commands.
+<li>Added the "-sourceid" option to the "sqlite3" command.
+<p><b>Makefile improvements:</b>
+<li>Improved pthreads detection in configure scripts.
+<li>Add the ability to do MSVC Windows builds from the <a href="../download.html">amalgamation tarball</a>.
+<p><b>Bug fixes</b>
+<li>Fix an issue with incorrect sharing of VDBE temporary registers between
+ co-routines that could cause incorrect query results in obscure cases. Ticket
+ <a href="https://www.sqlite.org/src/info/d06a25c84454a">d06a25c84454a</a>.
+<li>Fix a problem in the <a href="../c3ref/result_subtype.html">sqlite3_result_subtype()</a> interface that could
+ cause problems for the <a href="../json1.html">json1</a> extension under obscure circumstances.
+ Fix for ticket
+ <a href="https://www.sqlite.org/src/info/f45ac567eaa9f9">f45ac567eaa9f9</a>.
+<li>Escape control characters in JSON strings. Fix for ticket
+ <a href="https://www.sqlite.org/src/info/ad2559db380abf8">ad2559db380abf8</a>.
+<li>Reenable the xCurrentTime and xGetLastError methods in the built-in
+ unix <a href="../vfs.html">VFSes</a> as long as <a href="../compile.html#omit_deprecated">SQLITE_OMIT_DEPRECATED</a> is not defined.
+<p><b>Backwards Compatibility:</b>
+<li>Because of continuing security concerns, the two-argument version
+ of the seldom-used and little-known <a href="../fts3.html#f3tknzr">fts3_tokenizer()</a> function is
+ disabled unless SQLite is compiled with the <a href="../compile.html#enable_fts3_tokenizer">SQLITE_ENABLE_FTS3_TOKENIZER</a>.
+<p><b>Hashes:</b>
+<li>SQLITE_SOURCE_ID: "2016-02-15 17:29:24 3d862f207e3adc00f78066799ac5a8c282430a5f"
