<h2>Next Version (unreleased)</h2> <h2>Next Version (unreleased)</h2>
<ul><li>- <ul><li>The MySQL compatibility feature "insert ... on duplicate key update"
did not work with a non-default schema.
</li><li>Issue 599: the condition "in(x, y)" could not be used in the select list
when using "group by".
</li><li>The LIRS cache could grow larger than the allocated memory.
</li><li>A new file system implementation that re-opens the file if it was closed due
to the application calling Thread.interrupt(). File name prefix "retry:".
Please note it is strongly recommended to avoid calling Thread.interrupt;
this is a problem for various libraries, including Apache Lucene.
</li><li>MVStore: use RandomAccessFile file system if the file name starts with "file:".
</li></ul> </li></ul>
