Thankfully i was partially wrong and the vendor will support 4.8

Unfortunately that still leaves us vulnerable to some nasty bugs.

I can only speculate reasons but my suspicions are similar to whats been mentioned in this thread.

Thank you all very much for your assistance, i wholeheartedly agree with the sentiment expressed in your reply's. Unfortunately im a programmer not a politician, and can only hope logic will prevail... it makes me feel sick to think of the consequences.

 Due to the fact, that DNN 4.9.3 does not include breaking changes, I am sure, that your solution will work on latest version as well, except the module developers are using undocumented methods (oops, "inofficial" interfaces) or even do change the core (a no-go). I'd suggest to test it on a duplicated environment an look for a reliable provider of suitable solutions.
