Best way to update portableapps?

I was wondering how other people handle the issue of keeping their portableapps up to date? I know you can subscribe by RSS to PA.c news updates, but is there a program or anything that I could run which would check whether new versions of specific apps (i.e. the ones I have installed) exist?

I found this:

An outdated updater for portableapps. I am guessing this is exactly what I'm looking for - but I don't suppose I should use it as it's "OUTDATED!!!".

It mentions in this post that this updater functionality will be included in the PA.c platform version 2.0 beta 4.

Is this the case? Will the beta 4 include exactly this functionality that I'm looking for? Does anyone know when we might expect beta 4 to be released? And what is everyone else doing to keep their apps up to date in the mean time?

Thanks
Robin.
