Hi Michael,
I installed CU188 from the nightly onto a vm system and looked though all the WUI pages and everything looked fine.
I then restored a CU187 backup from my testing and then checked the OpenVPN RW and N2N. Both worked fine with no problems. Also the logging for that all worked with no problems.
Also checked out the IPS, IP Blocklists, Firewall groups and rules, DNS ...
Everything I have looked at shows no impact from the cleanup branch changes. It looks good to me.
Of course good for others to also evaluate.
Regards,
Adolf.
