Release Notes: Minor changes were made to work with Linux kernel 2.6.9.
Release Notes: This is the port to Linux 2.6.x. With this version, kernel 2.4.x is no longer supported: use the 1.x.x version for the old kernel.
Release Notes: Minor documentation changes were made.
Release Notes: This version fixes the mcount initialization value, and adds a check for the running kernel version in configure.ac. There are minor documentation changes in the README and man page.
Release Notes: A problem with "observer" where the noarp module did not correctly suppress the selection of the VIP as the sender IP address in ARP requests was fixed. This solved an issue where the back-end host was updating all ARP cache entries on the local net for the VIP with the MAC of the back-end host.
