Hello,

does this affect the iteration interface as described in the  
current manual or is this only some internal optimization?

Basically it changes `start`/`next`/`done` to `iterate`. The manual for the master branch already reflects the changes: [https://docs.julialang.org/en/latest/manual/interfaces/](https://docs.julialang.org/en/latest/manual/interfaces/)

The link gives a 404 for me. This one works [https://docs.julialang.org/en/latest/manual/interfaces.html#Interfaces-1](https://docs.julialang.org/en/latest/manual/interfaces.html#Interfaces-1).

For me it’s exactly the opposite 😮

Hmm I can confirm, it is the opposite now. This is weird, anyways both links are out there now.
