[LLVMdev] RFC: Drop support running LLVM on Windows XP
Nobody objected to raising the bar, so I think we can go ahead and do this. Keeping the XP support until 3.7 ships seems reasonable as it's less disruptive. Should we consider bypassing Vista and jumping to 7 as the lowest supported Windows version as David suggested? I think we should document 7 as the recommended baseline. After we start using some of the newer APIs, we can see if users complain and evaluate the burden of maintaining Vista support at that time.

Vista's mainstream support ended in 2012 and only has extended support until 2017, so it's sunsetting already. ~Aaron> > On Mon, Jul 13, 2015 at 2:28 PM, Greg Bedwell <gregbedwell at gmail.com> wrote: >> >> Hi all, >> >> It looks like this conversation stalled.

[LLVMdev] RFC: Drop support running LLVM on Windows XP
+1.
