 # Release notes
 
 ## 0.7
+* Basic set of user-configurable key bindings.
 * Sidebar: Added a "New Identity" button and a link to "about:help" if there no identities.
 * Faster drawing of certain UI elements: site icon and current heading in the left margin, unfocused input fields, timestamp at the end of the page.
 * History is not updated until a network request finishes.
