Similarly, + when doing <a href="../lang_update.html">UPDATE</a> on records that span multiple pages, only + the subset of pages that actually change are written to disk. + This is a low-level performance optimization only and does not + affect the behavior of TRIGGERs or other higher level SQL + structures. +<li> Queries that use ORDER BY and LIMIT now try to avoid computing + rows that cannot possibly come in under the LIMIT. This can greatly + improve performance of ORDER BY LIMIT queries, especially when the + LIMIT is small relative to the number of unrestricted output rows. +<li> The <a href="../optoverview.html#or_opt">OR optimization</a> is allowed to proceed + even if the OR expression has also been converted into an IN + expression. Uses of the OR optimization are now also + <a href="../eqp.html#or-opt">more clearly shown</a> in the <a href="../eqp.html">EXPLAIN QUERY PLAN</a> output. +<li> The query planner is more aggressive about using + <a href="../optoverview.html#autoindex">automatic indexes</a> for views and subqueries for which it is + not possible to create a persistent index. +<li> Make use of the one-pass UPDATE and DELETE query plans in the + <a href="../rtree.html">R-Tree extension</a> where appropriate. +<li> Performance improvements in the LEMON-generated parser. +<p><b>Bug fixes:</b> +<li> For the right-hand table of a LEFT JOIN, compute the values + of expressions directly rather than loading precomputed values + out of an <a href="../expridx.html">expression index</a> as the expression index might + not contain the correct value. Ticket + <a href="https://sqlite.org/src/info/7fa8049685b50b5aeb0c2">7fa8049685b50b5aeb0c2</a> +<li> Do not attempt to use terms from the WHERE clause to enable + indexed lookup of the right-hand table of a LEFT JOIN.
