Are there breaking changes involved in moving from Ruby 2.5 to 2.7? cc @kaihoffman @andyjeffries

Hi @alexellis 2.7 implements all methods etc from previous versions, it simply adds new features. 3.0 next year will be the one with potential breaking issues.

themoah commented 4 years ago

@alexellis it's only security fixes and some major GC improvement (alongside JIT). All new features will be released with 3.0.

Let's go for it then.
