quite a bit, new options and new features are regularly added :

https://grsecurity.net/changelog-stable.txt
https://grsecurity.net/features.php
https://grsecurity.net/compare.php

the patches are very actively maintained and working very well on
gentoo hardened, but once again I use only the sanitizing features,
not the RBAC system.

as a sysadmin, grsec have helped me quite a bit those last ten years,
most of the kernel security problems, 0 days, local roots . . . have
been useless against my grsec kernels ;) usefull ehen you provide a
shell to most of your customers/users !
