 <p>Updates for Praat are available from <code><font size=+1>praat.org</font></code> or <code><font size=+1>www.fon.hum.uva.nl/praat</font></code>.</p>

 <p>Given that we tend to release new Praat versions once or twice a month, you can probably guess whether it would be worth your while to have a look at <code><font size=+1>praat.org</font></code> or <code><font size=+1>www.fon.hum.uva.nl/praat</font></code> to see what is new, and perhaps download a new version.</p>
 <p>Praat improves continually, and old features will almost always continue to work, so there should never be a reason to continue to work with older versions.</p>
 <h2>Why no automatic update checking?</h2>
