With trepidation I upgraded to TBC 2026.1 last night (Kiwi time) - with a full uninstall through Cleaner (and advanced removal of Registry entrys) and then an offline install it took a few hours (some issues for me with my User Admin Rights from our company)
BUT it was a clean install and it seems to work ok - no errors nor crashes
ALSO the Rockpile macros I’ve tried all seem to work - yee hah!
Not extensive testing but it is nice to feel positive about a release for once!
