This theme http://wordpress.org/extend/themes/twentyeleven is still showing the latest version as 1.4 here. Its info need to be updated. Further, I suggest wordpress.org should have the 'changelog' tab on theme profiles as they exist on plugins profile page, so that anyone can see and find the summary changelog with statement points rather than a complete code trac like http://themes.trac.wordpress.org/changeset?old_path=/twentyeleven/1.4&new_path=/twentyeleven/1.5 . (although detailed code trac link can be provided within changelogs for technical users). It will surely help to keep track of changes for both developers and users for all themes and they can update it if they want.
