For older SFOS versions we have bunch of repositories as listed on the right of https://build.merproject.org/project...e:rinigus:maps . Just checked and the corresponding server version worked for SFOS 3.2

However, note that it is an effort to keep all the old SFOS versions and I may drop it soon. Reason is simple, right now we can stat using up-to-date gcc compiler and I don't have to do all these extra steps to compile recent code with the compiler installed in /opt/gcc. So, having new gcc is major improvement in SFOS 3.3 and you may get it more difficult to get updated software without it.

There is also an option for interested users to take over maintenance of these older versions. I am keeping opt-gcc available for older SFOS at its repository and, as it is, it would mainly require reverting one commit from today. But let's see if there is an interest at all ...
