New features and improvements in KSS
Multiline display of events
To improve readability, KSS NG now allows for the full display of multiline message text. Users are able to click and expand or collapse individual message lines, as well as toggle to show the full message text for all rows.
New macro $Message.RFCHost and changed logic for $Message.MsgHost
KSS NG now includes the macro $Message.RFCHost, which takes the host name from the RFC header of the message. If there is no RFC header, KSS NG will use the IP address.
The macro $Message.MsgHost now takes the host name from DNS data. If DNS is not available, KSS NG will use the IP address.
New filter workflow
KSS NG now offers an improved workflow for saved filters. Users are able to save up to twenty filters.
Additional log entries displayed on events page
KSS NG now displays up to 10,000 log entries on the events page.
General improvements
- Security enhancements.
- Angular framework upgraded to version 19.

Installation or upgrade
For new installations, you can download the installation file from the product page or the Customer Portal.
For information about how to install Releases, see the KSS NG Install Guide.
Releases is a separate application from the legacy version of Kiwi Syslog Server. If you installed the legacy version of Kiwi Syslog Server, you must either uninstall it or stop the KSS server before installing Releases. Legacy Kiwi Syslog Server and Kiwi Syslog Server NG cannot run on the same machine because they use the same listening ports.
