frequency of pkg updates

[David Newman]

How often is the FreeBSD pkg repository updated?

Asking because 'sudo pkg audit' sometimes shows vulnerabilities in one
or more packages, yet 'sudo pkg update && sudo pkg upgrade -f <pkg
name>' offers only to reinstall the vulnerable version.

An updated pkg can take days to show up. The ports tree is updated much
faster, but I'm trying to move to pkg where possible. (Yes, I know I
could run poudriere and create a pkg repository, but I'm asking here
about FreeBSD's pkg system.)

This is on 10.1-RELEASE-p4 amd64.

Thanks!
