frioux would be the best person to address the question

No - frioux tells me that he has nothing to do with the Strawberry Perl releases, and suggested contacting the Strawberry Perl mailing list, which I did.
The only reply I've received to that post was from zdm who suggested that the maintainer (AFAIK that is still kmx) might be on vacation.
I had sent kmx a private email a few days earlier but received no reply. Maybe his atlas.cz address is no longer active, or he couldn't be bothered replying, or he actually is on holiday.
Time will tell, I guess.

Cheers,
Rob
