Before answering, I'd point out you have a very significant potential
bug. Each of your __unicode__ methods actually uses str(). This will
work as long as you only use ASCII values, but as soon as you have
anything else - a name with an accent, a foreign currency symbol, or
whatever - it will die horribly and you will spend ages working out
why (believe me, I've been there).
Always, always return unicode from a __unicode__ method:
return unicode(self.name) + u' v' + unicode(self.version)
or, even better:
return u'%s v %s' (self.name, self.version)
Now, on to the question. It's actually related, in that the value that
gets printed there is the unicode of the inline model. If you want to
change the value, define a __unicode__ on ChangeLog. But to actually
remove the value, you'll need to override the inline template. You can
copy what's in django/contrib/admin/templates/admin/edit_inline/
tabular.html and just remove lines 25-28. Place the your overridden
template somewhere in your own templates directory, and put
template='path/to/your/template.html' in the ChangeInline admin class.
