Recently, Nokia has been in touch with some CSSU devs and the council about a Fremantle software update. As the version number implies, this is a simple fix for the DigiNotar issue and a fixed security control panel applet. The update should be released in a few days. Non-CSSU users can update immediately. If you ever want to install CSSU, the installer will work fine on PR1.3.1. Nokia has also agreed that the patches may be redistributed by the community and can be used in CSSU and Cordia.
