Description:
http://dev.mysql.com/doc/relnotes/mysql/5.7/en/news-5-7-5.html reads:

"
A new function, ANY_VALUE(), is available. Its return value and type are the same as the return value and type of its argument, but the function result is not checked for the ONLY_FULL_GROUP_BY SQL mode. The function does not make a nondeterministic query deterministic, but it can be used to force MySQL to accept queries that it thinks should be rejected with ONLY_FULL_GROUP_BY enabled.
"

This function is not yet described in the function reference.

How to repeat:
see http://dev.mysql.com/doc/relnotes/mysql/5.7/en/news-5-7-5.html

Suggested fix:
Please document ANY_VALUE() in the function reference.

Note that ANY_VALUE is *not* itself an aggregate function. This makes it a bit awkward, since it only means something in combination with GROUP BY.

Perhaps the best place to document this would be in http://dev.mysql.com/doc/refman/5.7/en/group-by-extensions.html since this is a function unique to MySQL which relates exclusively to GROUP BY.
