Plugin listed as using PHP4 constructors that will soon be unsupported

Hey there.

I use your plugin which works great, but recently saw a posting from a site with a list of plugins that may have issues due to a change in PHP constructors and in searching my plugin list, found that yours was listed:

Not sure if this is an issue or not, but just wanted to raise it, since I am a long time user of your great plugin.

Regards,

Michael
