My plan was to offer no more than two versions: N-1 and N, so that we
can add N, and give it some testing before having all users move
immediately from N-1 to N. This is pretty much what we do with gcc,
binutils and gdb as well. I believe the toolchain components are quite
critical, that's why we're a bit more conservative with these than with
the other components.

Do we have a reason to keep multiple versions for binutils, gcc and
gdb, but not for glibc?

Best regards,

Thomas
