To be clear on this: DataFrames, like most of the Julia ecosystem, follows SemVer. DataFrames 1.0 was released over two years ago (March 2021), and the API has been stable ever since.

Furthermore, Bogumil Kaminski, one of the main developers behind DataFrames, makes sure that the DataFrames tutorials he has created here (https://github.com/bkamins/Julia-DataFrames-Tutorial) are updated on every new release.

Beside the point. Old information on the internet abounds with the old syntax. It's a common hiccup for beginners in Julia. Ie they'd google something, try the syntax it errored out, they google it another way found it was updated try that nope that's outdated now too, etc. So it's worth mentioning.
