Minimum ruby version out of date?

[XuluWarrior]

I'm trying to install travis as per the README.

My MacOS system has ruby 2.6.10p210 installed, which presumably matches the "2.6.0 recommended" note.
But when I run gem install travis --no-document, I get the error

There are no versions of activesupport (~> 7.0.8) compatible with your Ruby & RubyGems. Maybe try installing an older version of the gem you're looking for?
	activesupport requires Ruby version >= 2.7.0. The current ruby version is 2.6.10.210.

Does this mean that the minimum version of ruby is now 2.7.0
