Tcl/Tk 8.6.9 (followed by Tk 8.6.9.1) was released recently. Among other things, they contain fixes for various issues on macOS, some of which have been seen by macOS users of IDLE and other tkinter apps, so the macOS installer should definitely be updated for 3.7.2, 3.6.8, and 2.7.16.

... and master.

I believe for Windows the policy has been to stick with one tcl/tk version for a Python version. But I don't know that this is written on stone. If not too much trouble, I would like master updated occasionally during the a1 period rather than just once around b1. I am not sure about backports.

The macOS installers will use Tcl 8.6.9 and Tk 8.6.9.1 starting with 3.7.2rc1 and 3.6.8rc1. Due to time constraints, the Windows builds will get updated later.

[zooba]

I pushed the raw Tcl and Tk sources for 8.6.9.0 to cpython-source-deps, but it looks like we need some patches to be able to build on Windows (the X11 headers #define some names that the Windows headers want to use as struct members).

So far I've needed to #undef and redefine None and ControlMask around #include <Windows.h> in winmain.c and tkWin.h, but I think that will be enough.

[zooba]

Looks like Tix needs similar updates, since it imports the Tk headers. Perhaps it'll be easier to undef immediately after the X11\X.h include? Assuming the values aren't actually being used anywhere.

[ned-deily]

Should the problems be reported upstream?
