Ruby 2.7.2 has been released and deprecated warnings will no longer be issued by default

Reprinted from Blog Article.

The other day, Ruby 2.7.2 was released.

• Ruby 2.7.2 release

With this release, The deprecated warning I mentioned the other day is no longer displayed by default. Therefore, in the future, if deprecated features are removed, the application may suddenly stop working. In order to avoid such problems, it is possible to develop safely in the future by "explicitly outputting deprecated warnings" as follows.

• Run Ruby with -w and -W: deprecated
• Add Warning [: deprecated] = true to the code
