<h2>SQLite Release 3.36.0 On 2021-06-18</h2><p><ol class='lessindent'>
<li> Improvement to the <a href="../eqp.html">EXPLAIN QUERY PLAN</a> output to make it easier to
understand.
<li> Byte-order marks at the start of a token are skipped as if they
were whitespace.
<li> An error is raised on any attempt to access the <a href="../lang_createtable.html#rowid">rowid</a> of a VIEW or subquery.
Formerly, the rowid of a VIEW would be indeterminate and often would be NULL.
The -DSQLITE_ALLOW_ROWID_IN_VIEW compile-time option is available to restore
the legacy behavior for applications that need it.
<li> The <a href="../c3ref/deserialize.html">sqlite3_deserialize()</a> and <a href="../c3ref/serialize.html">sqlite3_serialize()</a> interfaces are now
enabled by default. The -DSQLITE_ENABLE_DESERIALIZE compile-time option is
no longer required. Instead, there is a new <a href="../compile.html#omit_deserialize">-DSQLITE_OMIT_DESERIALIZE</a>
compile-time option to omit those interfaces.
<li> The "memdb" VFS now allows the same in-memory database to be shared among
multiple database connections in the same process as long as the
database name begins with "/".
<li> Back out the EXISTS-to-IN optimization (item 8b in the
<a href="../releaselog/3_35_0.html">SQLite 3.35.0 change log</a>)
as it was found to slow down queries more often than speed them up.
<li> Improve the <a href="../optoverview.html#constprop">constant-propagation optimization</a> so that it works on
non-join queries.
<li> The <a href="https://sqlite.org/src/file/ext/misc/regexp.c">REGEXP extension</a> is
now included in <a href="../cli.html">CLI</a> builds.
