+  The default ruby version has been updated from 2.7 to 3.0.
+
+  If you compile your own ports you may keep 2.7 as the default version by
+  adding the following lines to your /etc/make.conf file:
+
+  #
+  # Keep ruby 2.7 as default version
+  #
+  DEFAULT_VERSIONS+=ruby=2.7
+
+  If you wish to update to the new default version, you need to first stop any
+  software that uses ruby. Then, you will need to follow these steps, depending
+  upon how you manage your system.
+
+  If you use pkg, simply upgrade:
+  # pkg upgrade
+
+  If you do not use pkg, please check entry 20190420.
+  The description there should also work for this version.
