The link in the Customer Portal for the release notes takes me to Kiwi Customer Support | Kiwi which appears to be a generic page for support with no release notes in sight. Navigating Thwack using Product Forums > Kiwi Syslog Server > Documentation brings up 9.4.1... ?
The 9.4.2 information is now available:
Feature Updates - Kiwi Syslog Server | Kiwi
We are in the process of updating the documentation. In the meantime is there a specific question you have I can answer? The main issue we solved with 9.4.2 was adding support for running the product on Windows 2012 R2.
I see, thanks.
