I hope this will save time for developers whose tests fail like mine did.

 In [4767], we added a {{{mysql_old}}} backend, which is identical to the {{{mysql}}} backend prior to the change in [4724]. You can use this backend if upgrading the {{{MySQLdb}}} module is not immediately possible. However, the {{{mysql_old}}} backend is deprecated, and  we will not continue developing it.
 
+== Changed ModelForm's init signature to match Form's ==
+
+As of [6915] the {{{__init__}}} signature for {{{ModelForm}}} matches that of {{{newforms.Form}}}. {{{ModelForm}}} objects can now be instantiated by supplying the relevant form data without requiring a model instance to be passed in.
+
+Before the change {{{ModelForm}}} objects used in views were instantiated as follows:
+{{{
+   form = MyModelForm(instance, request.POST.copy())
+}}}
+
+This now becomes
+{{{
+   form = MyModelForm(request.POST.copy())
+}}}
