----------------------+--------------------------------
 Current version of Exim is 4.85. This updates Exim to that version.

 Also, according to the recommendations in #43431 ...

 * mysql5 variant is a stub for mysql51
 * mysql56 variant has been added
 * mariadb variant has been added

 I have tested all variants on OS X 10.9.5 and verified they work fine -
 including mysql4.

 Any reason not to remove the mysql4 variant? Exim only uses this for
 lookups and the mysql5 libraries should be able to search a mysql4 server
 fine (save for the password hashing). I do not have a mysql4 server to
 test with. I could install one but I'm honestly not inclined to.
