New versions of the NRPE (2.5) and NSCA (2.6) addons have been released. The new NRPE release fixes a few bugs in 2.4 and supports an allowed_hosts option in the config file (this was supported in earlier NRPE releases, but later removed). The NSCA release fixes a segfault, and adds support for reloading config via a SIGHUP and chroot jail. You can download both addons here.
