This should be done ASAP for most testing.

MacOS 64bit 3.7.0b1 links to 8.6.7.  Whether that should be upgraded to 8.6.8 is up to Ned.  I raised question on #15663.

This is on Steve these days due to the binary signing.

Yay, more work...

(btw Zach, nothing stopping you from putting the sources up for me :) I just need to hit the buttons to make the build.)

Yeah, we should do that for the macOS installers as well.

True :).  I'll get the sources up if I get a chance to do it before you do.

(Anyone else can feel free to take a crack at it as well, see https://github.com/python/cpython-source-deps/blob/master/README.rst for instructions that should hopefully work :))

I'll give it a shot.  :-)

I'm already most of the way through doing the sources this time - just running into ssh/GitHub troubles getting them online.

Still working on this - X11 and the WinSDK aren't playing nicely together. I might need a special build configuration to build this, or to submit fixes (and apply patches) to Tk.

Is "this will only be useful on Windows," in the source-deps readme still true? It appears that the tcl/tk tar.gz source is meant for Mac also.  (IE, has Xcode project files.)

Looking ahead, there is an 8.7a1 release.  I am hoping that 8.7 will be available for our 3.8, as it should include a rewritten Text widget that, among other things, will fix the slow long lines problem.  Do we wait for 8.7 final or do we start testing and, if necessary, adapting _tkinter and tkinter with, say, their .b1?

bpo-32901: Update Tcl and Tk versions to 8.6.8 (GH-5823)

The sources are just the original sources, so they could be useful on other platforms too.

The build on cpython-bin-deps is obviously only useful on Windows.

Windows is complete - leaving this open for Ned to resolve when the Mac installers are done.

New build with 8.6.8 seems to work fine on my machine.  Thanks.

I noticed that 'fetching tcl/tk 8.6.8' downloaded a pre-built binary instead of sources to build on my machine.  Nice.

The macOS installer builds do not use the cpython-source-deps repo.
