Hi Rajesh,<br> &nbsp;&nbsp;&nbsp;&nbsp; I am not a lawyer. Just telling you what I know. <br> &nbsp;&nbsp;&nbsp; Assuming you have written all of software X.1 you can relicense X.1 as anything you want. But people who got X.1 will forever be under GPL.<br> &nbsp;&nbsp;&nbsp; If you want to make X.5 proprietary, assuming that you wrote all the code for X.5 you are very much free to do so. You can change the license from GPL-&gt;NonGPL if you own all the software.<br>&nbsp;&nbsp; Also X.1 will always be under GPL, you cannot take that back.<br><br> -Krishna<br>BTW: Since you are taking community help in a bussiness decision, I request you to donate Rs. 500 (or atleast Rs. 100) to FSF India.<br>If you have more questions feel free to email me.<br><br><b><i>Rajesh Prakasam &lt;rprakasam@velankani.com&gt;</i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;">      <meta http-equiv="Content-Type"

Here goes the situation.&nbsp;&nbsp;&nbsp; <br> ---------<br> I have software X.1 which is GPL. I find it pretty useful and use it in the development of Software A, by way of just using the binary of software X.1. When I commercially release software A, I also release Software X.1 along with its GPL, but my Software A isn't GPL....meaning anything NON-GPL. In this circumstance, suppose Software X, from version X.5 decides to go NON-GPL, what are the implications that I have for Software X.1 that I already bundle with Software A.<br> <br> There are a couple of questions.<br> <br> a) Can this situation of a GPL software moving towards a non-GPL license over the time happen...???<br> b) Does the older GPL version X.1 also get affected by changes to version X.5...(rephrasing it )...Is a
 version of a software GPL released, GPL for ever or is it subject to change?<br> ---------<br> <br> I have been using Free Software mostly on personal basis, but now faced with a business decision to make, hence consulting the authority...:-)<br> <br> Thanks,<br> Rajesh<br> </blockquote><BR><BR>=====================================
