About this time last year, I covered Ruby on Rails 5.2 Deprecations and got lots of appreciative feedback. With the upcoming next major update of Ruby on Rails, I’d figure that I would do a new article and make it a tradition.
NOTE: Ruby on Rails 6.0 will require Ruby 2.5.0. So if you’re stuck on an older version of Ruby for whatever reason, you may want to consider holding off on updating your application to 6.0.
I will likely update this article as later betas and release candidates come.
