+  The default MySQL version has been updated from 5.7 to 8.0.
+
+  If you compile your own ports you may keep 5.7 as the default version by
+  adding the following lines to your /etc/make.conf file:
+
+  #
+  # Keep MySQL 5.7 as default version
+  #
+  DEFAULT_VERSIONS+=mysql=5.7
+
+  If you wish to update to the new default version, you need to first stop any
+  running server instance. Then, you will need to follow these steps, depending
+  on installed packages.
