[SeaBIOS] Advise on updating SeaBIOS in stable

[Anthony Liguori]

Hi,

I'm ready to cut another qemu stable release and I'm contemplating 
whether to update to 0.5.1 in stable.  Generally speaking, we try to 
limit stable to bug fixes and changes that aren't user visible.

0.5.1 looks like a point on the master branch as opposed to a separate 
branch.  I wonder what the thinking is within SeaBIOS about what sort of 
changes will be in the 0.5.x series vs. what would result in 0.6.0.

Regards,

Anthony Liguori
