Quicken has announced that they're gradually switching over from QIF
format to a different one. I can still import a QIF file in my quicken
Basic 2005. But don't know which year that will stop. I've notified the
authors of abp and RMRBank about this, but don't know if they'll ever
update their apps to handle the new format.
