<h1>Change Log</h1>
<h2>Next Version (unreleased)</h2>
<ul><li>-
<ul><li>Inserting rows in reverse order could throw an ArrayIndexOutOfBoundsException
in some cases (specially rows larger than the page size, which is 2 KB by default). Issue 226.
</li><li>H2 Console: with Chrome and Safari, resizing the table/query frame doesn't work. Issue 225.
</li><li>New experimental database file locking mechanism "FS" to use native file locking
(no *.lock.db file is created in this case, and no background thread is started). This mechanism
may not work on all systems (on some systems it's possible to lock the same file multiple
times within the same virtual machine, and on some system native file locking is not working
or unlocking is not working).
</li></ul>
