Yes, they changed the behavior of S-mouse-1.  It now does so-called text scaling
or resizing.  The library for this behavior is face-remap.el.  See for example
`text-scale-increase' and `text-scale-adjust' (`C-x C-+'). For the doc, see the
Emacs manual, node `Temporary Face Changes'.

Those functions resize/scale the buffer text, as I said.  An _alternative_ is to
change the font of the `default' face for a given _frame_. You can do that in
various ways.  Again, see the SetFonts wiki page.
