From the beta list post for the newest build:
Found and squashed the issue that was causing unexpected exceptions to be raised when processing certain books, such as GURPS Low-Tech 4e.gdf.
Fixed issue that raised an exception when the last character was closed, but GCA was not closed.
Added an Option to prevent most of the book-processing messages from appearing in the Log.
Added UI for Character Rules options in Options.
Fixed bug that was causing defaulted skills to get point happy.
