According to the website a new final of SFXMaker (1.3) was released on April 18th. http://www.isoft-online.com/
You're right. I missed that version because it's not mentioned on the changelog page
As I tried the new version it refused to start on a limited account (WinXP SP2). This was something new compared to the previous final (1.2.1). Can anyone confirm it?
On my system (64-bit Windows 7 SP1) SFXMaker 1.3 requires elevation (i.e. admin rights).
To me, additional portability is more important than the improvements in the new version. I have edited the entry
by adding a note about this and changing the download link to point pernamently to version 1.2.1.
