+  The default ruby version has been updated from 2.2 to 2.3.
+
+  If you compile your own ports you may keep 2.2 as the default version by
+  adding the following lines to your /etc/make.conf file:
+
+  #
+  # Keep ruby 2.2 as default version
+  #
+  DEFAULT_VERSIONS+=ruby=2.2
+
+  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 pkgng, simply upgrade:
+  # pkg upgrade
+
+  If you use portmaster, install new ruby, then rebuild all ports that depend
+  on ruby:
+  # portmaster -o lang/ruby23 lang/ruby22
+  # portmaster -R -r ruby-2.3
+
+  If you use portupgrade, install new ruby, then rebuild all ports that depend
+  on ruby:
+
+  # pkg delete -f ruby portupgrade
+  # make -C /usr/ports/ports-mgmt/portupgrade install clean
+  # pkg set -o lang/ruby22:lang/ruby23
+  # portupgrade -x ruby-2.3.\* -fr lang/ruby23
