From the CHANGES.txt file:

Changes for release 0.8.3

Fixed some weirdness in the display of the orientation option
for when editing radio button and checkbox group definitions.
This should now display consistently.

Removed the is_keyword option as it did not do anything (in Elgg 1.x
metadata is always searchable if you have the right access level).

Fixed the display of checkbox groups (previously these would only
display properly if only one had been selected).

Added a $_friendlytime template variable.

Fixed several problems with the group profile display and added a
"wide tabbed" display for groups that need more room for their profile
information.
