GRUB 1.97 released

GNU GRUB is upgraded to version 1.97. GRUB, also known as the GRand Unified Bootloader, is a modular, portable bootloader that supports a number of platforms & is included in many Linux distributions.

A source tarball for the new release can be found at:

and its GPG detached signature [*]:

[*] You can use either of the above signature files to verify that
the corresponding file (without the .sig suffix) is intact. First,
be sure to download both the .sig file and the corresponding tarball.
Then, run a command like this:

gpg --verify grub-1.97.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

gpg --keyserver --recv-keys DEA2C38E

and rerun the `gpg --verify' command.
