I=E2=80=99ll admit that back then I had neglected to upgrade the shared dae= mon at the MDC, missing the change to different compression types. A considerable chunk of the demand for gzip substitutes then could have been due to the MDC. Eventually, I did upgrade the shared daemon, so demand should have dropped significantly. > But there does seem to be users on foreign distros who never update > their daemon and don=E2=80=99t read news either.

Printing a warning is a good way to get people=E2=80=99s attention, so I=E2= =80=99m all for it to prepare for the big break. --=20 Ricardo
