Apologies to anyone who downloaded the 1.8.1 DMG file which was badly broken. A new version has been uploaded and should work as expected. Internal application updates were not affected by the DMG packaging bug.
This release updates the Greek localisation and has a couple of minor bug fixes. If anyone sees hangs when updating the port database let me know, I would be interested to know if it goes away after a selfupdate as well.
You can get Porticus 1.8.1 here.
I have started adding a little help to the web site, thanks to Jim Busser for providing the basis for this.
