+h3. Ubuntu 18.04 packages for arvados-api-server and arvados-workbench now conflict with ruby-bundler
+
+Ubuntu 18.04 ships with Bundler version 1.16.1, which is no longer compatible with the Gemfiles in the Arvados packages (made with Bundler 2.2.19). The Ubuntu 18.04 packages for arvados-api-server and arvados-workbench now conflict with the ruby-bundler package to work around this issue. The post-install scripts for arvados-api-server and arvados-workbench install the proper version of Bundler as a gem.

 h3. Removed unused @update_uuid@ endpoint for users.
 
 The @update_uuid@ endpoint was superseded by the "link accounts feature":{{site.baseurl}}/admin/link-accounts.html, so it's no longer available.
