I'd be surprised if it has been otherwise. :-)

First, as far as I know there is no way to set the resolution for PDF or
PostScript output. On the other hand, this is because it does not matter
for vector drawings (which are used by LilyPond) anyway. IIRC, PDF uses
like 32bit resolution on the positioning and size of objects, and this
exceeds by far what you're able to distinguish on a printout.
If there's a single program on this planet allowing you to get the
correct view at a high zoom level from the document, it's up to the
printing driver or rendering engine of your viewer.

Generally, you only have to bother with resolution settings unless you
have any rasterized part in your output (embedded PNG or something).
