Sorry, I was not aware. Doesn't seem to have been mentioned in the last month or so. Perhaps it could be included in the list introduction message? All people obviously won't read it, but some will.

A plain "please use reply all" would've sufficed.

Although I do appreciate the importance of guaranteed interfaces, I am also pragmatic. An incompatible change in ntdll.dll would break vast amounts of programs, including cygwin. There is a lot to be said about Microsoft and their APIs, but I don't think they have a habit of changing ABIs or function semantics for userland libraries that have been around for 15 years.

Okay, thanks. Just like you I hate wasting time, in my case with patches that'll be refused.
