+<h2>SQLite Release 3.12.2 On 2016-04-18</h2><p><b>Prior changes from version 3.12.0 (2016-03-29):</b></p>
+<p><ol class='lessindent'>
+<p><b>Potentially Disruptive Change:</b>
+<li value='1'>The <a href="../compile.html#default_page_size">SQLITE_DEFAULT_PAGE_SIZE</a> is increased from 1024 to 4096.
+    The <a href="../compile.html#default_cache_size">SQLITE_DEFAULT_CACHE_SIZE</a> is changed from 2000 to -2000 so
+    the same amount of cache memory is used by default.
+    See the application note on the
+    <a href="../pgszchng2016.html">version 3.12.0 page size change</a> for further information.
+<p><b>Performance enhancements:</b>
+<li>Enhancements to the <a href="../lemon.html">Lemon parser generator</a>
+    so that it creates a smaller and faster SQL parser.
+<li>Only create <a href="../tempfiles.html#superjrnl">master journal</a> files if two or more attached databases are all
+    modified, do not have <a href="../pragma.html#pragma_synchronous">PRAGMA synchronous</a> set to OFF, and
+    do not have the <a href="../pragma.html#pragma_journal_mode">journal_mode</a> set to OFF, MEMORY, or WAL.
+<li>Only create <a href="../tempfiles.html#stmtjrnl">statement journal</a> files when their size exceeds a threshold.
+    Otherwise the journal is held in memory and no I/O occurs.  The threshold
+    can be configured at compile-time using <a href="../compile.html#stmtjrnl_spill">SQLITE_STMTJRNL_SPILL</a> or at
+    start-time using <a href="../c3ref/config.html">sqlite3_config</a>(<a href="../c3ref/c_config_covering_index_scan.html#sqliteconfigstmtjrnlspill">SQLITE_CONFIG_STMTJRNL_SPILL</a>).
+<li>The query planner is able to optimize IN operators on <a href="../vtab.html">virtual tables</a>
+    even if the <a href="../vtab.html#xbestindex">xBestIndex</a> method does not set the
+    sqlite3_index_constraint_usage.omit flag of the
+    virtual table column to the left of the IN operator.
+<li>The query planner now does a better job of optimizing <a href="../vtab.html">virtual table</a>
+    accesses in a 3-way or higher join where constraints on the virtual
+    table are split across two or more other tables of the join.
+<li>More efficient handling of <a href="../appfunc.html">application-defined SQL functions</a>, especially
+    in cases where the application defines hundreds or thousands of
+    custom functions.
+<li>The query planner considers the LIMIT clause when estimating the cost
+    of ORDER BY.
+<li>The configure script (on unix) automatically detects
+    pread() and pwrite() and sets compile-time options to use those OS
+    interfaces if they are available.
+<li>Reduce the amount of memory needed to hold the schema.
+<li>Other miscellaneous micro-optimizations for improved performance and reduced
+    memory usage.
+<p><b>New Features:</b>
+<li>Added the <a href="../c3ref/c_dbconfig_defensive.html#sqlitedbconfigenablefts3tokenizer">SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER</a> option to <a href="../c3ref/db_config.html">sqlite3_db_config()</a>
+    which allows the two-argument version of the <a href="../fts3.html#f3tknzr">fts3_tokenizer()</a> SQL function to
+    be enabled or disabled at run-time.
+<li>Added the <a href="https://www.sqlite.org/src/artifact/d7cc99350?ln=403-443">sqlite3rbu_bp_progress()</a>
+    interface to the <a href="../rbu.html">RBU</a> extension.
+<li>The <a href="../pragma.html#pragma_defer_foreign_keys">PRAGMA defer_foreign_keys=ON</a> statement now also disables
+    <a href="../foreignkeys.html#fk_actions">RESTRICT actions</a> on foreign key.
+<li>Added the <a href="../c3ref/system_errno.html">sqlite3_system_errno()</a> interface.
+<li>Added the <a href="../compile.html#default_synchronous">SQLITE_DEFAULT_SYNCHRONOUS</a> and <a href="../compile.html#default_wal_synchronous">SQLITE_DEFAULT_WAL_SYNCHRONOUS</a>
+    compile-time options.  The <a href="../compile.html#default_synchronous">SQLITE_DEFAULT_SYNCHRONOUS</a> compile-time option
+    replaces the <a href="../compile.html#extra_durable">SQLITE_EXTRA_DURABLE</a> option, which is no longer supported.
+<li>Enhanced the ".stats" command in the <a href="../cli.html">command-line shell</a> to show more
+    information about I/O performance obtained from /proc, when available.
+<p><b>Bug fixes:</b>
+<li>Make sure the <a href="../c3ref/get_auxdata.html">sqlite3_set_auxdata()</a> values from multiple triggers
+    within a single statement do not interfere with one another.
+    Ticket <a href="https://www.sqlite.org/src/info/dc9b1c91">dc9b1c91</a>.
+<li>Fix the code generator for expressions of the form "x IN (SELECT...)" where
+    the SELECT statement on the RHS is a correlated subquery.
+    Ticket <a href="https://www.sqlite.org/src/info/5e3c886796e5512e">5e3c886796e5512e</a>.
+<li>Fix a harmless TSAN warning associated with the <a href="../c3ref/db_readonly.html">sqlite3_db_readonly()</a> interface.
+</ol>
+<p><b>Prior changes from version 3.12.1 (2016-04-08):</b></p>
+<p><ol class='lessindent'>
+<li value='21'>Fix a boundary condition error introduced by version 3.12.0
+    that can result in a crash during heavy <a href="../lang_savepoint.html">SAVEPOINT</a> usage.
+    Ticket <a href="https://www.sqlite.org/src/info/7f7f8026eda38">7f7f8026eda38</a>.
+<li>Fix <a href="../lang_createview.html">views</a> so that they inherit column datatypes from the
+    table that they are defined against, when possible.
+<li>Fix the query planner so that IS and IS NULL operators are able
+    to drive an index on a LEFT OUTER JOIN.
+</ol>
+<p><b>Changes in this specific patch release, version 3.12.2 (2016-04-18):</b></p>
+<p><ol class='lessindent'>
+<li value='24'>Fix a backwards compatibility problem in version 3.12.0 and 3.12.1:
+    Columns declared as <tt>"INTEGER" PRIMARY KEY</tt> (with quotes around
+    the datatype keyword) were not being recognized as an
+    <a href="../lang_createtable.html#rowid">INTEGER PRIMARY KEY</a>, which resulted in an incompatible database file.
+    Ticket <a href="https://www.sqlite.org/src/info/7d7525cb01b68">7d7525cb01b68</a>
+<li>Fix a bug (present since <a href="../releaselog/3_9_0.html">version 3.9.0</a>) that can cause the <a href="../lang_delete.html">DELETE</a>
+    operation to miss rows if <a href="../pragma.html#pragma_reverse_unordered_selects">PRAGMA reverse_unordered_selects</a> is turned on.
+    Ticket <a href="https://www.sqlite.org/src/info/a306e56ff68b8fa5">a306e56ff68b8fa5</a>
+<li>Fix a bug in the code generator that can cause incorrect results if
+    two or more <a href="../vtab.html">virtual tables</a> are joined and the virtual table used in
+    outer loop of the join has an <a href="../lang_expr.html#in_op">IN operator</a> constraint.
+<li>Correctly interpret negative "PRAGMA cache_size" values when determining
+    the cache size used for sorting large amounts of data.
+<p><b>Hashes:</b>
+<li>SQLITE_SOURCE_ID: "2016-04-18 17:30:31 92dc59fd5ad66f646666042eb04195e3a61a9e8e"
+<li>SHA1 for sqlite3.c: de5a5898ebd3a3477d4652db143746d008b24c83
