Is it possible to upgrade from 3.2a to 3.3 without having to disturb anything already installed. I have apache/mysql running as a service and 3.2a installed in C:\Uniform3_1_1s\ Which files should be replaced in order to upgrade? Also where can I find a changelog for v3.3? One more thing you might want to update http://miniserver.sourceforge.net/version.html to show version 3.3. edit : Also does the PEAR package work in 3.3, I could never get it to work on 3.2a, it always said class pear not found fatal error.
