Brief information for users of Sophos UTM. In mid-April 2020, in the article Stop: Don't install Sophos UTM 9.703 Firmware, I reported that the firmware update was pulled due to issues. Users should not install this update. Sophos has updated now it's advisory and acknowledged the errors. A revised firmware is now in tests – if that shows no problems, a revised version of the firmware will be available this week. I have added details in the linked article. Thanks to Thorsten for pointing this out.
