About Changing Book Format

Book format is changed in Egaroucid 6.3.0. The new book's filename extension is .egbk2. If you used version 6.2.0 or older and install 6.3.0, Egaroucid automatically translate book format in first execution. Also, you can use old .egbk book in "Book Reference" and "Book merge", but the save format is only new .egbk2.
