Dear all.

I’d like to release my software, which uses PyQt, under the MIT license. There used to be an exception that, if I understand correctly, allowed this. This was is the file called GPL_EXCEPTION.TXT that comes with the source distribution of PyQt 4.11.3 and earlier. However, from version 4.11.4 onwards and in PyQt5 this file is no longer present. Can you tell me if the exception has been revoked?

I know that this has been asked before in this mailing list here: https://riverbankcomputing.com/pipermail/pyqt/2014-February/033848.html <https://riverbankcomputing.com/pipermail/pyqt/2014-February/033848.html>. However, that answer mentions that the MIT is compatible with the GPL-3, which I believe is true as long as you release your software under the GPL (see https://www.gnu.org/licenses/gpl-faq.en.html#WhatDoesCompatMean <https://www.gnu.org/licenses/gpl-faq.en.html#WhatDoesCompatMean>). The exception would allow me to release my SW under the MIT license. 

Pepijn Kenter.
