I quickly skimmed Monty's changes to paranoia/, and almost all of them look like the changes backported from libcdio (mostly comments and a few bug fixes that originated in libcdio).
He has made a handful of other code changes that I need to examine (to understand and document), and then I plan to port those over to libcdio so that it's in sync with Xiph. Note that there will continue to be a little bit of divergence with Xiph, mostly due to the underlying infrastructure (libcdio vs. paranoia's direct SCSI access), but also because Monty chose not to merge in the TRACE_PARANOIA debug code. Interestingly, he also updated cdparanoia to LGPLv3 from GPLv2.
