My understanding is that the Stable Reference book (Introduction - The Rust Reference) is regularly updated from the Nightly versions of the book
(Introduction - The Rust Reference) whose content can be found as master branch of GitHub - rust-lang/reference: The Rust Reference
That said, what would be the best way to compare the current Stable Rust Reference book versus its content from 6 months ago ? Are there archived versions of past Stable versions of the Reference book or is this only considered a "moving target" and only its last state is available ?
(The reason I ask is because I would like to check what were the latest official adjustments on this official/stable version of the (stable) rust reference book )
Thanks
Eric
