[Pharo-project] Monticello diff between 2 version

Maybe I am not seeing it but: How do you see the changes between 2 version in a given repository in Monticello? And then, how do you export it to a simple fileout or record them in a change set. More specifically how can I extract the changes introduced by Collections-cmm.405.mcz Collections-cmm.404.mcz in source.squeak.org/trunk Thanks -- Miguel Cobá http://twitter.com/MiguelCobaMtz http://miguel.leugim.com.mx
