Rails has made changes to dump the schema(or structure) of the database when executing the command rails db:migrate:name. The command will also reset the `ActiveRecord::Base` connection after its execution.
Rails used to come with a lot of frameworks by default, when we generate a new application. Now Rails introduced minimal flag to generate an application with only bare minimum frameworks
Rails added web_image_content_types config option to ActiveStorage, which allows an application to add content types instead of letting the images be transformed into the fallback PNG format.
