When configuring your Amazon EC2 target in the rPath Management Console, you can now upload the text from a file to complete your key and certificate entries, so you don't have to copy and paste that text. rBuilder reads the file and pastes the contents into the field for you, but does not save the file itself.

rBuilder no longer displays the breadcrumb trail in the workspace title bar, and instead displays only the name of the current appliance or repository. (RBL-5066)

rBuilder administrators now see a message indicating that they do not have permissions when attempting to browse repository contents for appliances and repositories on which they are not a member.

rBuilder can now install and function properly without a fully-qualified domain name, provided it has a static IP address. (RBL-4567, RBL-4899)

NOTE: Though these features have been added starting with this rBuilder release, the API is not yet fully implemented, and some features may change over time.

This includes fixing direct links to appliances that worked in previous versions so that they work in this version. This means you can use a direct URL to open the home page of an appliance (or workspace if you're logged in as a member of its development team) without navigating the web interface to get there.
