Wrt this from way back https://dev.lucee.org/t/changing-isdebugmode-adding-isdebugoutputenabled/10691 Lucee 6.2.0.321 just seems to require debugging to be enabled i.e. it is working as per the above proposal. With e.g. Lucee 6.0.3.1, isDebugMode() returns true only if debugging is enabled and I have a template defined (with an IP range matching my current IP!!) If this has been a recent(ish) change, did an equivalent of the proposed isDebugOutputEnabled() ever get built? If not, is there another way I can work out if Lucee debug being shown on screen for the current request, which takes into account IP addresses?
