Are you installing grub to a disk or to a partition?
If it's to a partition, this is a normal message because GRUB has to
use blocklists in this case.
How large is the post-MBR gap? It looks like core.img has become
larger with the upgraded package, cannot be embedded into the post-MBR
gap, and therefore GRUB needs blocklists for core.img to be located
and loaded at boot.
