No, it is not buggy - in this case!. Documentation on-line or official distribution belongs to a release, in this case 3.2.0.
If you want up-to-date docs, you have to build them...
That does not mean the docs can not contain bugs, but not in this case. Here is it is a mismatch between versions.
There is a reason for that: many use the pre-built installers from the official repo. You can not go and document features or fixes that are not in that repo. Period.
