 For me it felt the other way around.  Well, not so much what I could
 filter (which is nearly everything), but the later versions allowed
 a bit better 'filter management' (searching through them, for one).
 What are you trying to achieve?  For instance, I filter this list
 by specifically going for the "List-Id" header attribute.  (I do
 the same for others.)  That usually works fine for me.
 
I stopped using Thunderbird so that's not really an issue anymore.
