Great new version!

I noticed that there is only a build for ubuntu platform. Will at least  
one of the other (older distribution) ones come back? Also the builds for  
ubuntu have different versions for 32 and 64 bit. 32bit is fine with the  
12.04 LTS, which is the newest LTS. But all the 64bit users who want or  
have to stick with the LTS version have to manually build it. Would it be  
possible to provide a prebuild 64bit precise version?
