bin/faxrcvd, bin/pollrcvd, and bin/notify are all considered to be part 
of the package distribution and as such are subject to change between 
package versions.  If you are dependent upon the particulars of any of 
those then you should copy it to "____.custom" and use the configuration 
of FaxRcvdCmd, PollRcvdCmd, or NotifyCmd to point to your "custom" 
versions that will not change through upgrades.

Correct.  The image itself has more data than it did before.

It's possibly because your new pdf rendering engine is creating "color" 
or "greyscale" PDFs instead of monochrome... causing Ghostscript to try 
to render the colors to monochrome in a meaningful way (and doing so 
poorly).  Make sure that the PDF is monochrome before submitting it to fax.
