+<h2>SQLite Release 3.22.0 On 2018-01-22</h2><p><ol class='lessindent'>
+<li> The output of <a href="../c3ref/trace_v2.html">sqlite3_trace_v2()</a> now shows each individual SQL statement
+     run within a trigger.
+<li> Add the ability to read from <a href="../wal.html">WAL mode</a> databases even if the application 
+     lacks write permission on the database and its containing directory, as long as
+     the -shm and -wal files exist in that directory.
+<li> Added the <a href="../rtree.html#rtreecheck">rtreecheck()</a> scalar SQL function to the <a href="../rtree.html">R-Tree extension</a>.
+<li> Added the <a href="../c3ref/vtab_nochange.html">sqlite3_vtab_nochange()</a> and <a href="../c3ref/value_blob.html">sqlite3_value_nochange()</a> interfaces
+     to help virtual table implementations optimize UPDATE operations.
+<li> Added the <a href="../c3ref/vtab_collation.html">sqlite3_vtab_collation()</a> interface.
+<li> Added support for the <a href="../fts5.html#carrotq">"&#94;" initial token syntax</a> in FTS5.
+<li> New extensions:
+<ol type='a'>
+  <li> The <a href="../zipfile.html">Zipfile virtual table</a> can read and write a 
+       <a href="https://en.wikipedia.org/wiki/Zip_(file_format)">ZIP Archive</a>.
+  <li> Added the fsdir(PATH) <a href="../vtab.html#tabfunc2">table-valued function</a> to the
+       <a href="https://sqlite.org/src/file/ext/misc/fileio.c">fileio.c</a> extension,
+       for listing the files in a directory.
+  <li> The <a href="https://sqlite.org/src/file/ext/misc/btreeinfo.c">sqlite_btreeinfo</a>
+       eponymous virtual table for introspecting and estimating the sizes of
+       the btrees in a database.
+  <li> The <a href="https://sqlite.org/src/file/ext/misc/appendvfs.c">Append VFS</a> is a
+       <a href="../vfs.html#shim">VFS shim</a> that allows an SQLite database to be appended to some other
+       file.  This allows (for example) a database to be appended to an
+       executable that then opens and reads the database.
+</ol>
+<li> Query planner enhancements:
+<ol type='a'>
+  <li> The optimization that uses an index to quickly compute an
+       aggregate min() or max() is extended to work with
+       <a href="../expridx.html">indexes on expressions</a>.
+  <li> The decision of whether to implement a FROM-clause subquery
+       as a co-routine or using <a href="../optoverview.html#flattening">query flattening</a>
+       now considers whether
+       the result set of the outer query is "complex" (if it
+       contains functions or expression subqueries).  A complex result
+       set biases the decision toward the use of co-routines.
+  <li> The planner avoids query plans that use indexes with unknown
+       collating functions.
+  <li> The planner omits unused LEFT JOINs even if they are not the 
+       right-most joins of a query.
+</ol>
+<li> Other performance optimizations:
+<ol type='a'>
+  <li> A smaller and faster implementation of text to floating-point
+       conversion subroutine: sqlite3AtoF().
+  <li> The <a href="../lemon.html">Lemon parser generator</a> creates a faster parser.
+  <li> Use the strcspn() C-library routine to speed up the LIKE and
+       GLOB operators.
+</ol>
+<li> Improvements to the <a href="../cli.html">command-line shell</a>:
+<ol type='a'>
+  <li> The ".schema" command shows the structure of virtual tables.
+  <li> Added support for reading and writing
+       <a href="../sqlar.html">SQLite Archive</a> files using
+       the <a href="../cli.html#sqlar">.archive command</a>.
+  <li> Added the experimental <a href="../cli.html#expert">.expert command</a>
+  <li> Added the ".eqp trigger" variant of the ".eqp" command
+  <li> Enhance the ".lint fkey-indexes" command so that it works with
+       <a href="../withoutrowid.html">WITHOUT ROWID</a> tables.
+  <li> If the filename argument to the shell is a ZIP archive rather than
+       an SQLite database, then the shell automatically opens that ZIP 
+       archive using the <a href="../zipfile.html">Zipfile virtual table</a>.
+  <li> Added the <a href="../cli.html#editfunc">edit() SQL function</a>.
+  <li> Added the <a href="../cli.html#exexcel*">.excel command</a> to simplify exporting
+       database content to a spreadsheet.
+  <li> Databases are opened using 
+       <a href="https://sqlite.org/src/file/ext/misc/appendvfs.c">Append VFS</a> when
+       the --append flag is used on the command line or with the
+       .open command.
+</ol>
+<li> Enhance the <a href="../compile.html#enable_update_delete_limit">SQLITE_ENABLE_UPDATE_DELETE_LIMIT</a> compile-time option so
+     that it works for <a href="../withoutrowid.html">WITHOUT ROWID</a> tables.
+<li> Provide the <a href="../lang_corefunc.html#sqlite_offset">sqlite_offset(X)</a> SQL function that returns
+     the byte offset into the database file to the beginning of the record
+     holding value X, when compiling with <a href="../compile.html#enable_offset_sql_func">-DSQLITE_ENABLE_OFFSET_SQL_FUNC</a>.
+<li> Bug fixes:
+<ol type='a'>
+  <li> Infinite loop on an UPDATE that uses an OR operator in the WHERE clause.
+       Problem introduced with 3.17.0 and reported on the mailing list about
+       one year later.  Ticket
+       <a href="https://www.sqlite.org/src/info/47b2581aa9bfecec">47b2581aa9bfecec</a>.
+  <li> Incorrect query results when the skip-ahead-distinct optimization is
+       used.
+       Ticket <a href="https://sqlite.org/src/info/ef9318757b152e3a">ef9318757b152e3a</a>.
+  <li> Incorrect query results on a join with a ORDER BY DESC.  Ticket
+       <a href="https://sqlite.org/src/info/123c9ba32130a6c9">123c9ba32130a6c9</a>.
+  <li> Inconsistent result set column names between CREATE TABLE AS
+       and a simple SELECT.  Ticket
+       <a href="https://sqlite.org/src/info/3b4450072511e621">3b4450072511e621</a>
+  <li> Assertion fault when doing REPLACE on an index on an expression.
+       Ticket <a href="https://sqlite.org/src/info/dc3f932f5a147771">dc3f932f5a147771</a>
+  <li> Assertion fault when doing an IN operator on a constant index.
+       Ticket <a href="https://sqlite.org/src/info/aa98619ad08ddcab">aa98619ad08ddcab</a>
