I am not too sure about what changes you exactly are looking to see.
Yes it does keep a log of all changes that are performed.
However if it is creation of clients then needless to say all clients which are created are listed.
If you want to view changes then there is an option
Utilities->Change Logs in which you can select the client and the duration period and it will reflect all the changes made if any.
Hope this is what you were looking for.
