+h3. Ubuntu 18.04 Arvados Python packages now depend on python-3.8
+
+Ubuntu 18.04 ships with Python 3.6 as the default version of Python 3. Ubuntu also ships a version of Python 3.8, and the Arvados Python packages (@python3-arvados-cwl-runner@, @python3-arvados-fuse@, @python3-arvados-python-client@, @python3-arvados-user-activity@ and @python3-crunchstat-summary@) now depend on the @python-3.8@ system package.
+
+This means that they are now installed under @/usr/share/python3.8@ (before, the path was @/usr/share/python3@). If you rely on the @python3@ executable from the packages (e.g. to load a virtualenv), you may need to update the path to that executable.
+
+h3. Minimum supported Ruby version is now 2.6
+
+The minimum supported Ruby version is now 2.6.  If you are running Arvados on Debian 10 or Ubuntu 18.04, you may need to switch to using RVM or upgrade your OS.  See "Install Ruby and Bundler":../install/ruby.html for more information.

 h3. Anonymous token changes
 
-The anonymous token configured in @Users.AnonymousUserToken@ must now be 32 characters or longer. This was already the suggestion in the documentation, now it is enforced. The @script/get_anonymous_user_token.rb@ script that was needed to register the anonymous user token in the database has been removed. Registration of the anonymous token is no longer necessary.

The @script/get_anonymous_user_token.rb@ script that was needed to register the anonymous user token in the database has been removed. Registration of the anonymous token is no longer necessary. If the anonymous token in @config.yml@ is specified as a full V2 token, that will now generate a warning - it should be updated to list just the secret (i.e. the part after the last forward slash).
