This feature won't be in v1.0, mainly because it is possible via existing Subversion clients, and therefore there is a simple workaround for now. Is there any reason why you hoped not to install a Subversion client?
In order to browse the history of any file or schema object script, you'll need an SVN client tool.
We'll definitely add more features in a later version, as we recognize this will improve the ease of setting up the system in the first place. Likewise, we hope to make the history available from within the tool.
