+<h2>SQLite Release 3.19.0 On 2017-05-22</h2><p><ol class='lessindent'>
+<li> The <a href="../c3ref/c_alter_table.html">SQLITE_READ</a> <a href="../c3ref/set_authorizer.html">authorizer callback</a> is invoked once
+ with a column name that is an empty string
+ for every table referenced in a query from which no columns are extracted.
+<li> When using an index on an expression, try to use expression values already
+ available in the index, rather than loading the original columns and recomputing
+ the expression.
+<li> Enhance the <a href="../optoverview.html#flattening">flattening optimization</a> so that it is able to flatten views
+ on the right-hand side of a LEFT JOIN.
+<li> Use <a href="../lang_corefunc.html#replace">replace()</a> instead of <a href="../lang_corefunc.html#char">char()</a> for escaping newline and carriage-return
+ characters embedded in strings in the .dump output from the <a href="../cli.html">command-line shell</a>.
+<li> Avoid unnecessary foreign key processing in UPDATE statements that do not
+ touch the columns that are constrained by the foreign keys.
+<li> On a DISTINCT query that uses an index, try to skip ahead to the next distinct
+ entry using the index rather than stepping through rows, when an appropriate
+ index is available.
+<li> Avoid unnecessary invalidation of <a href="../c3ref/blob.html">sqlite3_blob</a> handles when making
+ changes to unrelated tables.
+<li> Transfer any terms of the HAVING clause that use only columns mentioned in
+ the GROUP BY clause over to the WHERE clause for faster processing.
+<li> Reuse the same materialization of a VIEW if that VIEW appears more than
+ once in the same query.
+<li> Enhance <a href="../pragma.html#pragma_integrity_check">PRAGMA integrity_check</a> so that it identifies tables that have two
+ or more rows with the same <a href="../lang_createtable.html#rowid">rowid</a>.
+<li> Enhance the <a href="../fts5.html">FTS5</a> query syntax so that <a href="../fts5.html#fts5_column_filters">column filters</a>
+ may be applied to arbitrary expressions.
+<li> Enhance the <a href="../json1.html#jex">json_extract()</a> function to cache and reuse parses of JSON
+ input text.
+<li> Added the <a href="https://sqlite.org/src/file/ext/misc/anycollseq.c">anycollseq.c</a>
+ <a href="../loadext.html">loadable extension</a> that allows a generic SQLite database connection to
+ read a schema that contains unknown and/or
+ application-specific <a href="../datatype3.html#collation">collating sequences</a>.
+<p><b>Bug Fixes:</b>
+<li> Fix a problem in <a href="../lang_replace.html">REPLACE</a> that can result in a corrupt database containing
+ two or more rows with the same <a href="../lang_createtable.html#rowid">rowid</a>. Fix for ticket
+ <a href="https://www.sqlite.org/src/info/f68dc596c4e6018d">f68dc596c4e6018d</a>.
+<li> Fix a problem in <a href="../pragma.html#pragma_integrity_check">PRAGMA integrity_check</a> that was causing a subsequent
+ <a href="../lang_vacuum.html">VACUUM</a> to behave suboptimally.
+<li> Fix the <a href="../pragma.html#pragma_foreign_key_check">PRAGMA foreign_key_check</a> command so that it works correctly with
+ foreign keys on <a href="../withoutrowid.html">WITHOUT ROWID</a> tables.
+<li> Fix a bug in the b-tree logic that can result in incorrect duplicate answers
+ for IN operator queries. Ticket
+ <a href="https://sqlite.org/src/info/61fe9745">61fe9745</a>
+<li> Disallow leading zeros in numeric constants in JSON. Fix for ticket
+ <a href="https://www.sqlite.org/src/info/b93be8729a895a528e2">b93be8729a895a528e2</a>.
+<li> Disallow control characters inside of strings in JSON. Fix for ticket
+ <a href="https://www.sqlite.org/src/info/6c9b5514077fed34551">6c9b5514077fed34551</a>.
+<li> Limit the depth of recursion for JSON objects and arrays in order to avoid
+ excess stack usage in the recursive descent parser. Fix for ticket
+ <a href="https://www.sqlite.org/src/info/981329adeef51011052">981329adeef51011052</a>.
