GRUB 0.xx is considered to be "GRUB Legacy", or as I call it, "GRUB1" ]

http://grub.enbug.org/, but I haven't seen hardly any updates for YEARS!
GRUB2 is still being worked on. On certain occasions, I was curious about its development and have become familiar with its source code. It's very well designed from the start, and the developers are extremely careful not to introduce any new bugs. This is why it's constantly in the beta stages.
IMHO, despite the fact that it's still "beta", I think GRUB2 is already done and ready for use. It's completely stable, at least on x86 architectures, and I've never had it crash or do anything out of the ordinary. The only real issue is (again, in my opinion) its lack of documentation, and I'm pretty sure this stems from the fact that some of the lead developers are not native English speakers!
If you want to try it (GRUB2) out for the first time, I recommend doing it on a brand new blank disk, ideally a cheap USB flash drive, where you can test it out and get comfortable with it. It's possible to learn to use it just by diving in and testing stuff out.
Warning: A bootloader has to write to the MBR, and it will overwrite the old MBR. If you try to install GRUB2 to your main hard drive before you know how to use GRUB2, you will most definitely find yourself bashing your head against the keyboard (I try to do this at least once a day). Also, I find it particularly frustrating when people speak of GRUB without acknowledging which version they're talking about: the result is mass confusion around the internet when it comes to GRUB. So make sure you don't add to the confusion: read the documentation.
