I do not want to encourage anybody, but, just to share my personal experience, I have installed the Fujileaks FW 4.0 early this morning (Central Europe Time) and I have used it all the day without any trouble and with much satisfaction. I do not know if the final official version will be different and, if this is the case I will be able to install it over the Fujileaks version, but after this test really I do not care.
