I interpret this as a gentle suggestion that I upgrade instead. And I know that you're all volunteers. :)
Per the following announcement, Ruby 2.2.7 was released on March 28, 2017:
And, per the following external site (for what it's worth), the entire Ruby 2.2 series reached end-of-life on March 31, 2018:
After the moment when the new build environment started working, was it perhaps simply true that nobody wanted, or requested, a RubyInstaller2 download for any of the newer Ruby 2.2 series releases (beginning with 2.2.7)? Historically, could this have happened?
I don't want the old build environment, particularly.
Would you be able to tell me definitely, explicitly and truthfully that Ruby version 2.2.6 was built only with the old build environment (and not with the new one)? And more importantly, that Ruby version 2.2.10 cannot be built with the new build environment?
If it can't be built with the new build environment, would you give me a clue as to why not? :)
You say, "try to build." But that certainly wouldn't be helpful advice, if you happened to know already that building Ruby version 2.2.10 with the new build environment would turn out to be impossible.
Actually, I am willing to volunteer to build Ruby 2.2.10 with the new build environment if you assure me that, as far as you know, it is possible to succeed.
For other users (like me) who want to use this version, would my build be made available on the official downloads page?
