Suggestion: "Nightly" Builds

[ryancinsight]

Using "nightly" loosely but having an option to use the greatest in newest release candidate could help debug early on/find bugs that didn't previously cause issues due to new usage/allow users to test new improvements and if need be delay distribution with the new more significant changes in speed from previous versions.

I'm supportive of this.

But the main reason we don't have this is supporting the latest CPython branch tends to require a lot of code changes over the evolution of a major CPython release. I've found it easier to just set aside 1-2 days every year to apply all changes in bulk than to attempt to track upstream more closely.

There's a compelling argument that it would be easier to adopt to upstream changes if we were building off the latest CPython branches. But if we do this, I can't make any guarantees that builds remain green. python-build-standalone is very much something I prefer to touch once every few months and I'd prefer to not get sidetracked by random CPython commits breaking our build.

I'll look into this
