[MC] Diffing arbitrary versions?

Hi Guys -

I want to see a diff between two arbitrary package versions in
Monticello. It looks like there isn't a UI for this (the "diff" button
looked good at first but I couldn't figure out what it does) so does
anyone have a quick doIt for diffing versions?

Thanks,
   - Andreas

Hit History, and pop up the context menu on the items in the lefthand  
list.  You can use that to a) get a diff to the topmost version in  
the history list, or b) spawn a new history window with the selected  
item at the top.

Ah, great! I had no idea. BTW, can you explain what the "diff" button
actually does? It claims to "create an equivalent version based on an
earlier release" but what exactly does that mean? (I kinda expected this
button to offer me a history where I could choose a version from for
creating a diff ;-)

Cheers,

It should let you choose a previous version - it then creates a new  
Version object that only stores the diff between that previous  
version and the later one (which gets saved as a .mcd file,  
not .mcz).  To do anything with the .mcd later you need to have  
access to the previous version the diff is based on.
