Using 5.1.0 for commercial project
Are versions below 5.1.0 (final) stable, scalable and have complete XMPP implementation?
I will not redistribute but will use it after customization as a backend to my commercial application. Please can you elaborate if they are free versions to use under GPLv3 or do I need to pay for anything over there.

One of the suggestion on SO says:
Tigase is a typical backend system and as long as you do not redistribute it with some modifications under some other label, you shouldn't worry about GPL. Simply use it for your backend needs.
I was wondering if this is true and any of those older versions (under GPL and not AGPL) can be used for commercial purpose (without having need to publish anything of the server side source)

Our intention when we decided to release our code under an AGPL (GPL for older versions) license was to encourage people to kind of a fair use of our software. If you use it for free (under AGPL) license, go ahead but contribute back by releasing source codes of the software. If you do not want to release source codes, then please contribute back by buying a commercial license. As much as we would like to offer everything completely for free, it is not quite possible as we have to feed ourselves.
That was our intention and our way to support the project development but for real legal implications and advice I recommend to contact a lawyer who should be able to give you a definite answers what is legally acceptable with under the AGPL license.
