How to generate article in Middleman v4

Hello guys, I am new to Middleman and Middleman is really awesome but i am having hard time trying to generate https://middlemanapp.com/basics/blogging/#generating-articles

I use the command on that section and It output “Could not find command “article”.”

And then i found this issues on githup https://github.com/middleman/middleman/issues/1708

It seems that the generate command is removed :frowning:
Back to the question, How do i generate article? Are the only way now is by creating it manually?
and writing {year}/{month}/{day}/{title}.html manually? Or are there any new command to generate this.

Thank you

It should be back now, if you upgrade blog to to 4.0.1
