If <method> is 'os', installation will be to O/S- + and distribution-specific locations, such as /usr/sbin, /usr/lib/nagios, + /etc/nagios, and so on. +* Added additional init and inetd config files to support more systems, + including SuSE, Debian, Slackware, Gentoo, *BSD, AIX, HP-UX, Solaris, OS X. +* Added listen_queue_size as configuration option (Vadim Antipov, Kaspersky Lab) +* Reworked SSL/TLS. See the README.SSL.md file for full info. (John Frickson) +* Added support for version 3 variable sized packets up to 64KB. nrpe will + accept either version from check_nrpe. check_nrpe will try to send a + version 3 packet first, and fall back to version 2. check_nrpe can be forced + to only send version 2 packets if the switch `-2` is used.
