Nothing has intentionally changed. We've had another report of a problem
(in the opposite direction ... fonts were too big) so maybe there is
something going wrong in the code to handle DPI. I'd certainly like
a test case.

The main 1.2.3 => 1.2.4 change that seems relevant here is:

        * pango/pangoft2-fontmap.c (pango_ft2_font_map_default_substitute):
        Move DPI substitution before FcDefaultSubstitute so
        it actually works.

So, possibly the problem is that you were simply relying on fontconfig's
default DPI value before and not setting it correctly yourself. 

Hmm, are you using
pango_ft2_font_map_new()/pango_ft2_font_map_create_context()
the old pango_ft2_get_context()?
