I found the one you mean, i think: https://forums.mydigitallife.net/threads/iso-for-latest-enus-ltsb.72600/#post-1304719
It should be called 2018 LTSC, according to MSFT documents: https://forums.mydigitallife.net/threads/windows-10-hotfix-repository.57050/page-263#post-1408156
Look into basebrd.dll itself with strings.exe (or strings2.exe) and it's better to check \.rsrc\RCDATA\1 file only
can't wait for this new version! it will be running just as good as LTSB 1607, never had any problems and i use LTSB since the release of windows 10. 1-2 more months until it's out i guess?
