+<h2>SQLite Release 3.8.8.1 On 2015-01-20</h2><p><b>Prior changes from version 3.8.8 (2015-01-16):</b></p>
+<p><ol class='lessindent'>
+<p><b>New Features:</b>
+<li value='1'>Added the <a href="../pragma.html#pragma_data_version">PRAGMA data_version</a> command that can be used to determine if
+ a database file has been modified by another process.
+<li>Added the <a href="../c3ref/c_checkpoint_full.html">SQLITE_CHECKPOINT_TRUNCATE</a> option to the
+ <a href="../c3ref/wal_checkpoint_v2.html">sqlite3_wal_checkpoint_v2()</a> interface, with corresponding enhancements
+ to <a href="../pragma.html#pragma_wal_checkpoint">PRAGMA wal_checkpoint</a>.
+<li>Added the <a href="../c3ref/stmt_scanstatus.html">sqlite3_stmt_scanstatus()</a> interface, available only when
+ compiled with <a href="../compile.html#enable_stmt_scanstatus">SQLITE_ENABLE_STMT_SCANSTATUS</a>.
+<li>The <a href="../c3ref/table_column_metadata.html">sqlite3_table_column_metadata()</a> is enhanced to work correctly on
+ <a href="../withoutrowid.html">WITHOUT ROWID</a> tables and to check for the existence of a
+ a table if the column name parameter is NULL. The interface is now
+ also included in the build by default, without requiring
+ the <a href="../compile.html#enable_column_metadata">SQLITE_ENABLE_COLUMN_METADATA</a> compile-time option.
+<li>Added the <a href="../compile.html#enable_api_armor">SQLITE_ENABLE_API_ARMOR</a> compile-time option.
+<li>Added the <a href="../compile.html#reverse_unordered_selects">SQLITE_REVERSE_UNORDERED_SELECTS</a> compile-time option.
+<li>Added the <a href="../compile.html#sorter_pmasz">SQLITE_SORTER_PMASZ</a> compile-time option and <a href="../c3ref/c_config_covering_index_scan.html#sqliteconfigpmasz">SQLITE_CONFIG_PMASZ</a>
+ start-time option.
+<li>Added the <a href="../c3ref/c_config_covering_index_scan.html#sqliteconfigpcachehdrsz">SQLITE_CONFIG_PCACHE_HDRSZ</a> option to <a href="../c3ref/config.html">sqlite3_config()</a>
+ which makes it easier for applications to determine the appropriate
+ amount of memory for use with <a href="../c3ref/c_config_covering_index_scan.html#sqliteconfigpagecache">SQLITE_CONFIG_PAGECACHE</a>.
+<li>The number of rows in a <a href="../lang_select.html#values">VALUES clause</a> is no longer limited by
+ <a href="../c3ref/c_limit_attached.html#sqlitelimitcompoundselect">SQLITE_LIMIT_COMPOUND_SELECT</a>.
+<li>Added the <a href="https://www.sqlite.org/src/artifact/f971962e92ebb8b0">eval.c</a>
+ <a href="../loadext.html">loadable extension</a> that implements an eval() SQL function that will recursively
+ evaluate SQL.
+<p><b>Performance Enhancements:</b>
+<li>Reduce the number of memcpy() operations involved in balancing a b-tree,
+ for 3.2% overall performance boost.
+<li>Improvements to cost estimates for the <a href="../optoverview.html#skipscan">skip-scan optimization</a>.
+<li>The <a href="../optoverview.html#autoindex">automatic indexing</a> optimization is now capable of generating
+ a <a href="../partialindex.html">partial index</a> if that is appropriate.
+<p><b>Bug fixes:</b>
+<li>Ensure durability following a power loss with
+ "PRAGMA journal_mode=TRUNCATE" by calling fsync() right after truncating
+ the journal file.
+<li>The query planner now recognizes that any column in the right-hand
+ table of a LEFT JOIN can be NULL, even if that column has a NOT NULL
+ constraint. Avoid trying to optimize out NULL tests in those cases.
+ Fix for ticket
+ <a href="https://www.sqlite.org/src/info/6f2222d550f5b0ee7ed">6f2222d550f5b0ee7ed</a>.
+<li>Make sure ORDER BY puts rows in ascending order even if the DISTINCT
+ operator is implemented using a descending index. Fix for ticket
+ <a href="https://www.sqlite.org/src/info/c5ea805691bfc4204b1cb9e">c5ea805691bfc4204b1cb9e</a>.
+<li>Fix data races that might occur under stress when running with many threads
+ in <a href="../sharedcache.html">shared cache mode</a> where some of the threads are opening and
+ closing connections.
+<li>Fix obscure crash bugs found by
+ <a href="http://lcamtuf.coredump.cx/afl/">american fuzzy lop</a>. Ticket
+ <a href="https://www.sqlite.org/src/info/a59ae93ee990a55">a59ae93ee990a55</a>.
+<li>Work around a GCC optimizer bug (for gcc 4.2.1 on MacOS 10.7) that caused the
+ <a href="../rtree.html">R-Tree extension</a> to compute incorrect results when compiled with -O3.
+<p><b>Other changes:</b>
+<li>Disable the use of the strchrnul() C-library routine unless it is
+ specifically enabled using the -DHAVE_STRCHRNULL compile-time option.
+<li>Improvements to the effectiveness and accuracy of the
+ <a href="../lang_corefunc.html#likelihood">likelihood()</a>, <a href="../lang_corefunc.html#likely">likely()</a>, and <a href="../lang_corefunc.html#unlikely">unlikely()</a> SQL hint functions.
+
+</ol>
+<p><b>Changes in this specific patch release, version 3.8.8.1 (2015-01-20):</b></p>
+<p><ol class='lessindent'>
+<li value='22'>Fix a bug in the sorting logic, present since version 3.8.4, that can cause
+ output to appear in the wrong order on queries that contains an ORDER BY clause,
+ a LIMIT clause, and that have approximately 60 or more columns in the result set.
+ Ticket <a href="https://www.sqlite.org/src/tktview?name=f97c4637102a3ae72b79">f97c4637102a3ae72b79</a>.
