Changes 5.7.16:

Security Notes
--------------
* Incompatible Change: For STANDALONE and WIN builds, the default \ 
secure_file_priv value has changed from the empty string to NULL. This is a \ 
secure-by-default setting because it disables import and export operations. To \ 
permit those operations, set secure_file_priv to the path name of the directory \ 
to use for those operations.
* The linked OpenSSL library for the MySQL Commercial Server has been updated to \ 
version 1.0.1u. For a description of issues fixed in this version, see \ 
http://www.openssl.org/news/vulnerabilities.html.
This change does not affect the Oracle-produced MySQL Community build of MySQL \ 
Server, which uses the yaSSL library instead.

Functionality Added or Changed
------------------------------
* yaSSL was upgraded to version 2.4.2. This upgrade corrects issues with: \ 
Potential AES side channel leaks; DSA padding for unusual sizes; the \ 
SSL_CTX_load_verify_locations() OpenSSL compatibility function failing to handle \ 
long path directory names.
