Hi Everyone,

Today we've released UTM 9.503. The release will be rolled out in phases. In phase 1 you can download the update package from our FTP server, in phase 2 we will spread it via our Up2Date servers.

Update 2017-08-25: Unfortunately the update package has an issue with a missing config file for Samba and we needed to pull the update package down from the FTP server. We are working on a replacement urgently.

Update 2017-08-31: New update files with the fix for the missing Samba config (NUTM-8702) are available on our FTP server. There are two update files available now:

Update 2017-09-07: Update is available for all via Up2Date servers.
