@TAV1702 and @Shrikar,
It's always best to stay in safe zone but keep in mind that most internet service providers are upgrading their PHP to higher versions, so it would be wise if phpVMS gets upgraded ahead of time cause once the ISP upgrades their services then problems will start showing up with phpVMS. Also, as an add-on creator, I will create my future modules on newer versions of phpVMS and since I do this free, I will not have time to create them for old versions too.
