I did know that I've read it summarized somewhere!
The changes with the different releases are documented here:
http://midas.psi.ch/elog/download/ChangeLog

It is actually not so difficult to find: 
it is linked on the "Download" section http://midas.psi.ch/elog/download.html

"News for each version can be seen in the changelog (->http://midas.psi.ch/elog/download/ChangeLog)"

And for version 3.0.0 it states:
- Create one logbook subdirectory pear year

I admit that version 3.0 has never been announced and the changelog is not mentioned in the announcement of version 3.1.0
Maybe we'll do better in the future ;-)
