Update: Due to issues with our download server, portable gis is not currently available. Investigations are taking place as to the exact cause and I will announce when it is fixed, though this may take a few days as I am away over the weekend. Thanks for your patience and your interest!
Version 1.2 of Portable GIS has been released today, addressing a number of bugs in Version 1.1. Thanks to everyone who provided feedback and spotted the bugs. If you use, or intend to use, the web-based components of Portable GIS, or the OpenEV viewer, then this is a recommended update.
The download is available here, along with a patch to convert version 1.1 to 1.2. Please read the instructions provided in the patch file as the process is slightly complicated.
Feedback is, as ever, greatly appreciated, and thanks to the 100 or so people who have downloaded the first version!
