- New: Show Password checkbox has been added to the lock dialog.
- New: The notifications are now disabled even if the program is locked. The
notification dialog will be disabled but a large lock icon will be visible to the
user to unlock the program. While locked, any other actions on the notification
dialog are disabled.
- Updated: The WhoIs server was changed to who.is because it has better results for
IPv6 addresses. With the old networktools.nl server, only the IPv4 were resolved
correctly.
