I checked the current doc on date formats, I still saw the first format. Given that we are years after the release of 7.0 I'm confused if I need to update my custom dates in a couple of indices:
Someone, please answer. I can't wait weeks for a simple question that some guys didn't follow up in the documentation or misinterpreted during writing the release notes.
The recommendation is that if you were using Y in Joda time to indicate "year of era", you should now use y in Java time. And if you were using y in Joda time to indicate "year", you should now use u.
Nonetheless, because u and y are both valid in Java time, and behave similar for most use cases, I think the documentation is correct, and I will close this issue.
