Obviously this is sad news, especially for those of us who were hoping for an update for ESXi 6.5 compatibility, guess I'll have to downgrade to ESXi 6!
Nevertheless I completely understand your decision. Thank you for all the work you've put into this project over the years, hopefully someone comes along and takes over
I have a probable solution to ESXi 6.5 so my parting shot will be to try and finish it up and release before the end of the month. I have enjoyed working on the unlocker plus all is predecessors, and I am pleased it has been of use to many in the community.
