Although the official update to version 9.5 is not yet available, Sophos has released a mini update today. The update raises the version of UTM 9 to 9.412-2:
The update contains the following bug fixes:
- Fix [NUTM-7483]: [Basesystem] Optimize LPC usage
- Fix [NUTM-7564]: [SUM] RED Link state is shown wrong in Gateway Manager

- tools-9.40-2.g78bd00c.rb3.i686.rpm
- ep-init-9.40-16.ga469d4d.noarch.rpm
- ep-release-9.412-2.noarch.rpm

With version 9.5 there will also be Exchange templates for the WAF, but these are not yet completely up-to-date:
But the article linked above refers to a solution
