Compiler fixes are being continuously checked in, but the people who write the changelogs don't always remember to ask the compiler devs for a list. Nor did they ask me for a list of STL fixes.

I keep track of all STL fixes that are checked in, so I can write VCBlog posts about them (as I did for CTP1 [1], and will do again for RTM). But I don't immediately know what got into CTP6 - I'd need to ask somebody to verify what branch it was built from, or install it in a VM. I also keep track of STL features and compiler features (again for VCBlog posts) but not compiler fixes - there are just too many fixes and I can't accurately describe most of them.

Approximately 80 STL bugs in our internal database (including Connect) have been fixed after CTP1. Notably, I overhauled <functional> to fix all known bugs, with the only limitation being Expression SFINAE. If the CTP6 branch is $/devdiv/Rel/D14Rel as the version number would seem to indicate, then it appears to contain both the overhaul and my later implementation of C++17 std::invoke(). This also means it contains fixes for several compiler bugs that I encountered along the way, including the interaction of PMDs with rvalues, and partial ordering among variadic templates.
