I'm not sure which version you were previously using, but mine was a very neanderthal version of miltiMAN which I had installed during my Kmeaw phase. So for me, it was a giant leap when I got the latest bunch of updates. Most notable change is the interface which looks really amazing and is absolutely smooth. Besides that the discless compatibility has increased, accessing NTFS partition is much easier through file manager, games which require firmware above 4.30 can be patched directly at launch, temperatures can now be monitored, PSX games can be loaded and yes, from the recent change-log, it does seems like you can switch Blu-Ray region coding too. So yes, it's miles better than what it was before. I almost have a hard time catching up with it's updates.
