3.2.1.36 pr Command Behavior Now Works as Described in Reference Page
The pr command has been modified to handle the i [character] [gap] option
(which replaces multiple space characters with tab characters) so that it performs as
documented in the pr(1) reference page.
3.2.1.37 Kit's Session Log Made More Useful
If you view the session log for this release, you may notice that it is smaller than it has
been in the past. We edited this file to remove non-essential information that the system
generates automatically.
3.2.1.38 Sys_Check Version 143 Provided
This kit includes Sys_Check Version 143. However, HP recommends that you visit the
sys_check website to download and install the version there if it is more recent than
Version 143:

3.2.1.39 New Variables Protect Against Attack
This kit provides two new kernel tunable variables, tcp_rst_win and tcp_syn_win
to protect systems against potential vulnerabilities called TCP RST attack and TCP SYN
attack. For more information, see “Potential Security Vulnerability Identified” and a
revised sys_attrs_inet(8) reference page, which is installed with this kit.
3.2.1.40 New fuser Option Aids Query Search
A new option, -a, has been added to the fuser command to expand a query to search
of all cluster members. See the fuser(8) reference page for more information.
3.2.1.41 New /etc/printcap Option Provided
This kit provides a new boolean /etc/printcap option, sr, to suppress the reprinting
of jobs under conditions that indicate to the print daemon that a reprint is needed. The
syntax for this entry is similar to that of the sh (suppress header) option.
You can use this option to suppress an unexpected or unneeded reprinting of jobs that
are completed but are reprinted a second time due to miscommunication between the
printer and the print daemon.
