Ruby security announce mailing list?

I’m looking for a mailing list to subscribe regarding ruby security to
know at once when a new version is released and what the actual security
flaw is and if there is a workaround for it.

I checked on ruby-lang but couldn’t seem to find one dedicated to this.
Could anyone kindly point me to the right direction?

Thanks.

Anyone?

Thanks vladm!
