Let's go with adding a SECURITY.md with some basic things, I'll submit a PR so we can work out the verbiage. Do we need to update the security page with an abbreviated version? I'm not a fan of having duplicated information across the two especially for this which might change rapidly and have the potential to go stale. > > Mark > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [email protected] > For additional commands, e-mail: [email protected] > >
