<li>The SQL output resulting from [sqlite3_trace()] is now modified to include
the values of [parameters | bound parameters].
<li>Performance optimizations targetting a specific use case from
a single high-profile user of SQLite. A 12% reduction in the number of
CPU operations is achieved (as measured by valgrind). Actual performance
improvements in practice may vary depending on workload. Changes

We believe that [http://www.ge.com/ | General Electric]
uses SQLite in some product or
another because they twice wrote the to SQLite developers requesting
the US Export Control Number for SQLite. So presumably GE is using
SQLite in something that they are exporting. But nobody
(outside of GE) seems to know what that might be.
