Until the 15th of June, it is still possible to download in the old version. This is why the idea is to still keep it alive, so the .PRO is still the main user database.
I have cloned .NET, for you this morning.
It mean that you can now see your last changes done in .PRO, visible in .NET (copy)
Now, you can download in .NET and see the source.
If you change something in .NET (for example you add a filter, or a field in form, change properties....) All this you can do freely, but at the next clone, you will lost them. So if you want to modify important stuff, do it in .PRO
I know it is a bit strange but with my limited knowledge, it is the best I could do for the moment for this important migration.
For example, if you want to try the new State filter, you can but you can only try it from .NEt because it does not exists under 2.0 (.PRO)
It means, you cannot really instance State filter in .PRO and everytime you want to download in .NEt, you must recreate it if the clone has occured.
.NET beta is only for you to check the new code, and for you to start forking your projects.
I don't know if you already started to custom your component under 2.0 (I guess not if you are new here)
Forking means that now you must separate your custom in the way it is explained. A kind of Cook standard for developping fast and efficiently.
I invite you to read this doc :

Last but not least :
The support forum is free for all. I voluntary do not see from the forum if you have paid or not. It is my philosophy. When you tell me that you can download, it always means that you have paid something.
