For comparison, when building with Clang 8 and 9, the number of packages that could not be built was higher.

It has been barely 10 years since the RoS developers (in stable 6.47) added functionality that allows DNS requests to be redirected according to specific rules. Previously, one had to convolute with Layer-7 rules in the firewall, but now it's done simply and elegantly: /ip dns static add forward-to=192.168.88.3 regexp=».*\.test1\.localdomain» type=FWD add forward-to=192.168.88.56 regexp=».*\.test2\.localdomain» type=FWD My happiness knows no bounds!
