And don't forget to read your News. In this case, there is an item in the very first entry about embedFonts:

Here's a way to search for any others:

[1] "embedFonts() now defaults to format = \"ps2write\" for .ps and .eps\nfiles.  This is available in Ghostscript 9.x (since 2010) whereas\nthe previous default, format = \"pswrite\", was removed in\nGhostscript 9.10."
[2] "Error messages from bugs in embedded Sexpr code in Sweave documents\nnow report the source location."                                                                                                                 
[3] "read.table(), readLines() and scan() have a new argument to\ninfluence the treatment of embedded nuls."                                                                                                               
[4] "read.table(), readLines() and scan() now warn when an embedded nul\nis found in the input.  (Related to PR#15625 which was puzzled by\nthe behaviour in this unsupported case.)"
