RLIKE: "." no longer matching new line

In 5.5.36, RLIKE and REGEXP work as they always have:

SELECT 

'cat and

 dog' 

RLIKE 'cat.*dog';

=> 1

In 10.0.10, 

SELECT 

'cat and

 dog' 

RLIKE 'cat.*dog';

=> 0

I consider this to be a critical issue that would cause queries to not function as expected.
