About older versions of the program

[corttex]

I noticed that older versions of the program (4.9.0) are no longer supported by you, (as it says in the message when I try to start the program and that I have to update), and do not work anymore, so I wonder if version 4.9.5 will also stop working in a while, and if every version of the program will stop working if it's not updated in say a couple of months or so.
