After some nice user making me notice that I was laging 3 years behind with the uDig version in the osgeo for windows installer, I wrapped myself up and with the gentle help of the osgeo guys (I had 2 tickets open since 3 years :( ) I got back on track.
The result is that uDig 1.2.1 is available in the osgeo4w installer. I really like the installer of osgeo4w and I will definitely put also BeeGIS as an installation option into it.
Want to try it out? Just run the installer here.
