Hello *,
Core Update 178 (master/41e33931) is running here without any issues for roughly a day now. A very minor finding is that vulnerabilities.cgi does not give human- readable names and CVEs for the new vulnerabilities, but that is by no means a show-stopper, and I'll prepare a patch for fixing this.
IMHO, Core Update 178 is ready to be released.
Thanks, and best regards, Peter Müller
